EnglishWhat Is Iconer? A Free Icon Library and Customization App
Updated
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.

How to use it
- Search or browse for the icon you need, using the license, type, and tag filters to narrow results.
- Open the icon in the app to see its editable attributes.
- Adjust the attributes the library supports — for example, increase stroke width or switch between round and sharp corners.
- 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.
