iconer.app

Iconer aggregates 20+ open-source icon libraries in one place, so you can browse, compare, and customize icons from Feather, Ionic, Heroicons, Tabler, Material, and many others without visiting each source separately. The libraries differ mainly by icon count, license (MIT, Apache 2.0, ISC, CC BY 4.0, or Unlicense), and style (line, solid, sharp, round). If you need a specific license for commercial use or a particular visual style, use the table below to pick the right library before you start editing.

Full library list with counts, categories, and licenses

The table below reflects what Iconer lists on its site. Icon counts and category counts are as shown; licenses are the ones each library ships with.

| Library | Icons | Categories | License | Styles | |---|---|---|---|---|---| | Feather Icons | 286 | 30 | MIT | line | | Ionic Icons | 1193 | 34 | MIT | line, sharp, solid, round | | Heroicons | 448 | 26 | MIT | line, solid | | Tabler Icons | 1520 | 36 | MIT | line | | Cssgg Icons | 704 | 31 | MIT | line, sharp, round | | Eva Icons | 401 | 29 | MIT | line, solid, round | | Bootstrap Icons | 1668 | 45 | MIT | line, solid, round | | Iconpark Icons | 2437 | 30 | Apache 2.0 | line | | Material Icons | 2946 | 30 | Apache 2.0 | line, solid, sharp | | Remix Icons | 2213 | 36 | Apache 2.0 | line, solid, sharp, round | | Bytesize Icons | 101 | 26 | MIT | line | | Ikonate Icons | 327 | 35 | MIT | line | | Iconoir Icons | 1007 | 32 | MIT | line | | Basil Icons | 473 | 27 | CC BY 4.0 | line, solid, round | | Boxicons | 1578 | 41 | MIT | line, solid, round, sharp | | Teeny Icons | 1055 | 35 | MIT | line, solid, sharp, round | | Phosphor Icons | 2094 | 34 | MIT | line, solid, round | | Lineawesome Icons | 1393 | 39 | MIT | line, sharp | | Radix Icons | 333 | 25 | MIT | line, solid, round | | Mono icons | 180 | 27 | MIT | line, round | | Lucide icons | 541 | 34 | ISC | line | | Systemui Icons | 420 | 32 | Unlicense | line | | Basicons | 225 | 21 | MIT | line | | Jam Icons | 940 | 34 | MIT | line |

How to choose a library for your project

The right pick depends on three things: license, style consistency, and icon count.

• License first. If you need maximum freedom with no attribution, MIT, ISC, and Unlicense libraries are the simplest. Apache 2.0 (Iconpark, Material, Remix) also permits commercial use but includes a notice requirement. CC BY 4.0 (Basil) requires attribution.
• Style consistency. Mixing a line-only library like Feather with a solid-and-sharp set like Material will look inconsistent. Pick one library per project, or one style variant across libraries.
• Coverage. For broad UI needs, Bootstrap Icons (1668 icons, 45 categories) and Material Icons (2946 icons) cover the most ground. For a minimal, uniform look, Feather (286) or Mono (180) keep things tight.

Quick picks by use case

• Minimal line UI: Feather, Lucide, Iconoir, Mono
• Large general-purpose set: Material, Iconpark, Remix, Phosphor
• Multi-style flexibility (line/solid/sharp/round): Remix, Boxicons, Teeny, Ionic
• Framework-aligned: Heroicons (Tailwind-style), Bootstrap Icons, Radix
• No-attribution, permissive: Systemui (Unlicense), Lucide (ISC), any MIT set

What you can do with a library once you pick one

Iconer lets you search, remix, and download royalty-free icons in SVG, PNG, HTML, JSX, and more. After choosing a library, you can edit attributes (such as stroke width, linecap, and linejoin where supported) and copy or export in your preferred format. The customization options vary by library — for example, Bytesize exposes stroke width, linecap, and linejoin, while Feather exposes stroke width and round.

If you are unsure which library fits, start with the style filter (line, solid, sharp, round) and the license filter, then sort by popularity. That narrows the list to a handful of candidates you can preview side by side.

Iconer supports exporting icons in SVG, PNG, HTML, and JSX, plus "more" formats according to the site's own description. The right choice depends on where the icon will live: SVG for scalable web use, PNG for raster needs, JSX for React components, and HTML for direct markup embedding. Export is done by copying or downloading from the app after you customize an icon.

Supported export formats at a glance

Iconer's homepage states you can "Search, remix and download royalty free icons for any project in SVG, PNG, HTML, JSX and more," so treat this list as the confirmed set and expect additional formats beyond it.

How to export an icon

1. Find an icon — search or browse by library, category, or tag.
2. Customize it — adjust attributes such as stroke width, and for some libraries round, sharp, solid, or line style. The available controls depend on the source library (for example, Feather Icons exposes stroke width and round; Material Icons exposes solid and sharp).
3. Choose your format — pick SVG, PNG, HTML, or JSX depending on your target.
4. Copy or download — the site describes the process as "copy and export effortlessly," so either copy the code/output or download the file.

The expected result is a ready-to-use icon asset in the format you selected, with your customizations applied.

Choosing the right format

• Use SVG when the icon must stay crisp at any size or you want to style it with CSS. This is the default choice for most web and app work.
• Use PNG when your destination can't handle vectors — for example, pasting into a slide deck or a tool that only accepts images.
• Use JSX when you're building a React interface and want the icon as a component rather than an image file.
• Use HTML when you want to drop the icon directly into a page's markup without a separate asset file.

What to check before exporting

• License — Iconer aggregates libraries under different licenses, including MIT, Apache 2.0, ISC, CC BY 4.0, and Unlicense. The license travels with the icon, so confirm it fits your project before shipping.
• Library-specific attributes — not every library supports every style toggle. If a control you expect is missing, the source library likely doesn't offer it.
• Source style — libraries are tagged as line, solid, sharp, or round. Pick a library whose base style matches your design so you customize less.

If you only need one takeaway: default to SVG for anything on the web, switch to PNG for raster-only destinations, and use JSX or HTML when you want the icon inline in code.

Iconer lets you edit icon attributes — such as stroke width, corner style, and line caps — directly in the browser before you copy or export. Open any icon library in the app, select an icon, and adjust the controls shown for that library; the preview updates immediately. The exact options depend on the library, because each one exposes only the attributes its source files support.

What you can customize

Iconer groups its libraries by the kind of source they use, and the editable attributes follow from that:

• Stroke width — available on line-style libraries such as Feather, Tabler, Lucide, Iconoir, and Phosphor.
• Corner and join style — round, sharp, or solid variants appear on libraries like Ionic, Heroicons, Bootstrap, Boxicons, and Teeny.
• Line caps and joins — Bytesize exposes linecap and linejoin in addition to stroke width.
• Style variants — some libraries ship multiple weights or fills (line, solid, sharp, round) that you switch between rather than edit numerically.

Not every control appears on every icon. A solid-only set has no stroke width to change, and a library that ships a single style won't offer a variant toggle.

Step-by-step

1. Open a library. From the Iconer home view, pick a set — for example Feather Icons (286 icons, MIT), Tabler Icons (1,520 icons, MIT), or Material Icons (2,946 icons, Apache 2.0).
2. Find an icon. Use search, or filter by category (Animals, Apps, Brand, Communications, Devices, Food, Graphics, People, Real World, UI) and tag. You can also filter by license and type, and sort by popularity.
3. Select it. The icon opens in the app view, where the editable attributes for that library are listed.
4. Adjust the attributes. Change stroke width, or toggle round/sharp/solid, depending on what the library exposes. The preview reflects each change as you make it.
5. Copy or export. Once the icon looks right, copy it or download it in your chosen format (SVG, PNG, HTML, JSX, and others).

Expected result: you get an icon file or snippet matching the attributes you set, without editing the source by hand.

Choosing a library for the attributes you need

Licenses vary across the catalog: most libraries are MIT, Iconpark/Material/Remix are Apache 2.0, Basil is CC BY 4.0, Lucide is ISC, and Systemui is Unlicense. Check the license shown on the library before you ship an icon, since the terms differ.

Common snags

• A control you expected isn't there. The attribute isn't part of that library's source. Switch to a library that exposes it, or accept the fixed style.
• The icon looks different after export. Some formats rasterize at a fixed size; export SVG or JSX if you need the edited attributes preserved as vectors.
• You can't find a matching icon. Widen the search by clearing tag filters, or try a larger set like Material or Iconpark.

Iconer's customization is attribute-level editing on top of existing libraries, not a from-scratch drawing tool — so the fastest path is usually to pick the library whose editable attributes already match the look you want, then fine-tune from there.

Iconer is a free icon platform that lets you search, customize, and download royalty-free icons from multiple open-source libraries in formats including SVG, PNG, HTML, and JSX. It suits developers, designers, and anyone who needs consistent icons for a project and wants to adjust attributes like stroke width or corner rounding before exporting. All icon sets listed on the site carry open licenses (mostly MIT, with some Apache 2.0, ISC, CC BY 4.0, and Unlicense), so you can use them commercially as long as you follow each library's terms.

What you can do on Iconer

The site organizes its catalog around a single search-and-edit workflow:

• Search and filter — browse by license, type, or tag, and sort by popularity.
• Pick from many libraries — each library shows its icon count, category count, license, and available styles.
• Customize attributes — depending on the library, you can adjust stroke width, linecap, linejoin, and round or sharp corners.
• Export in multiple formats — download or copy icons as SVG, PNG, HTML, JSX, and more.

The homepage groups icons into categories such as Animals, Apps, Brand, Communications, Devices, Food, Graphics, People, Real World, and UI.

Icon libraries available

Iconer aggregates a large number of open-source sets. The table below lists the libraries shown on the site with their icon counts, licenses, and supported styles.

How to use it

1. Search or browse for the icon you need, using the license, type, and tag filters to narrow results.
2. Open the icon in the app to see its editable attributes.
3. Adjust the attributes the library supports — for example, increase stroke width or switch between round and sharp corners.
4. Copy or export the result in your target format (SVG, PNG, HTML, JSX, or another listed option).

The exact controls depend on the library, since not every set exposes the same attributes.

Choosing a library

Use these dimensions to decide:

• License fit — MIT and Apache 2.0 sets are permissive and common for commercial work; check CC BY 4.0 (Basil) for attribution requirements, and Unlicense (Systemui) for public-domain-style terms.
• Style match — pick a set whose available styles (line, solid, sharp, round) match your design system.
• Coverage — larger sets like Material (2,946), Iconpark (2,437), and Remix (2,213) give more icons per style; smaller sets like Bytesize (101) or Mono (180) are easier to keep consistent.
• Editability — if you need to tweak stroke width or corner rounding, choose a library that lists those attributes.

Key things to know

• Iconer itself is a customization and export layer; the underlying icons come from third-party open-source libraries, so the license of the specific library applies to your use.
• The site describes its icons as royalty-free, but "royalty-free" here reflects the open licenses listed per library — always confirm the license shown for the set you pick.
• Format support (SVG, PNG, HTML, JSX, and more) means you can drop icons directly into web, app, or design workflows without converting manually.

Iconer hosts icon libraries under several open-source licenses, and the license is shown on each library's card. According to the site's library listing, the licenses in use are MIT, Apache 2.0, CC BY 4.0, ISC, and Unlicense. The license is set per library, not per icon, so the same site can contain libraries with different terms. Before you use an icon, check the license label on the library you took it from.

Licenses seen on Iconer

The library counts on Iconer range from small sets (Bytesize, 101 icons) to large ones (Material Icons, 2,946 icons), so license choice can matter depending on which library fits your design.

How to check the license for a specific icon

1. Open the Iconer app and browse or search for an icon.
2. Find the library card or library detail for the set the icon belongs to (for example, "Tabler Icons" or "Material Icons").
3. Read the License field on that card. Iconer displays it alongside the icon count, category count, and source style.
4. If you need the full legal text, follow the license name to its official page (for example, MIT, Apache 2.0, CC BY 4.0, ISC, or Unlicense).

The license is attached to the library, so switching from a MIT library to an Apache 2.0 or CC BY 4.0 library changes your obligations even though the icons are in the same app.

What this means for your project

• MIT, ISC, and Unlicense libraries are the most permissive on Iconer. They are generally safe for commercial and closed-source projects, provided you keep the required notice where the license asks for it.
• Apache 2.0 libraries (Iconpark, Material Icons, Remix Icons) are also permissive but include a patent grant and notice requirements, which some teams prefer for that reason.
• CC BY 4.0 (Basil) requires attribution. If you cannot or do not want to credit the source, this library is a poorer fit than the MIT sets.
• Attribution is not uniform. MIT and ISC typically require the copyright notice and license text to be included; CC BY 4.0 requires credit to the creator. Check the specific library rather than assuming all "free" icons work the same way.

Common pitfalls

• Assuming one license covers the whole site. Iconer mixes MIT, Apache 2.0, CC BY 4.0, ISC, and Unlicense libraries, so a blanket assumption is wrong.
• Treating "free" as "no conditions." CC BY 4.0 in particular carries an attribution condition that MIT-style licenses handle differently.
• Losing track after export. Iconer lets you copy and export in SVG, PNG, HTML, JSX, and more. Once an icon leaves the app, the license label does not travel with it, so record the source library and license in your project notes.
• Forgetting modified icons. If you remix or edit attributes, the original license still applies to the derivative in most cases.

If your project has strict licensing rules, start by filtering to MIT or Unlicense libraries, then confirm the license field on each library card before exporting.
