What is HiCompress?
HiCompress is a free browser-based toolkit for everyday image and PDF jobs. Its focus is quick, batch-friendly processing: compressing, converting, resizing, cropping and removing backgrounds, plus a set of PDF utilities such as merging, splitting and extracting images. Nothing is installed and, per the site, no registration is required.
What it actually does
The toolset falls into a few clear groups:
- Compression: JPG, PNG, WEBP and GIF, with lossy and lossless options, plus target-size tools such as compressing to 50KB or 100KB.
- Conversion: PNG, JPG, WEBP, HEIC, BMP, TIFF and camera RAW formats (CR2, CR3, NEF, ARW, ORF, PEF, RAF) to JPG, with bulk conversion.
- Resizing and editing: resize, crop, DPI changes and a batch background remover.
- PDF tools: JPG to PDF, merge, split, delete pages, PDF to JPG, and image extraction from PDFs.
The site describes itself as having 50+ tools, with claims of reducing file size by up to 80% (or 90% for the general image compressor) and GIF compression of roughly 30–50%.
Who it suits
It fits people who need a fast result without software: someone preparing photos for a job application portal that caps uploads at 100KB, a small seller resizing product shots for a marketplace, or an office worker merging scanned pages into one PDF. Because it handles HEIC and RAW, it is also handy for iPhone and camera users who just need a JPG.
The trade-offs are the usual ones for free online converters. Target-size compression means the site decides how much quality to sacrifice, so keep originals. Uploading confidential documents, IDs or client material to any web service is a judgement call — check the privacy terms before doing so. And browser tools are less precise than desktop editors when you need exact colour, metadata or print-ready output.
A practical next step
Start with the single task you have: if a form rejects your file, use the compress-to-50KB or 100KB tool; if a site won't accept HEIC or RAW, use the converter. Compare the result at 100% zoom before deleting the original. For heavier or more private work, desktop alternatives include ImageMagick for scripted conversion and compression, and GIMP for hands-on editing.
How do I compress images to a specific file size like 50KB or 100KB without losing quality?
You can compress to a target size like 50KB or 100KB, but "without losing quality" is not fully achievable — any size reduction removes some data. What you can do is hit the target while keeping quality loss invisible at normal viewing sizes. HiCompress offers dedicated tools for this: its page lists "Compress image to 50KB" and "Compress image to 100KB," both described as handling JPG, PNG and WEBP in bulk HiCompress. That is the fastest route if you just need files under a form or upload limit.
A practical workflow
- Start from the largest original you have. Re-compressing an already-compressed file stacks artifacts. If possible, export a fresh JPEG from your editor at high quality first.
- Resize before you compress. File size scales roughly with pixel count. A 4000px-wide photo will fight you at 100KB; a 1600px-wide version will not. HiCompress includes a separate Resize Image tool if you need it HiCompress.
- Compress to the target. Use the 50KB or 100KB tool for a hard ceiling, or the general JPG/PNG/WEBP compressors when you only want a sensible reduction.
- Check at 100% zoom. Look at edges, text and smooth gradients (skies, skin) — that is where compression shows first.
Choosing the right target
| Situation | Sensible approach |
|---|---|
| Web page images | Aim for visual quality, not a fixed KB; 100–200KB is usually plenty for a hero image |
| Email attachment or upload form with a hard limit | Use the 50KB/100KB tool and accept mild softening |
| Screenshots, logos, line art | PNG or WEBP lossless often beats JPEG at the same size |
| Photos for print | Do not target 50KB; keep the file large |
Format trade-offs
- JPG — best size-to-quality ratio for photographs, but no transparency and it blurs sharp text.
- PNG — keeps transparency and crisp edges; often much larger for photos.
- WEBP — usually the best of both, and HiCompress supports lossy and lossless WEBP compression HiCompress.
If you are working with iPhone photos, note that HEIC files can be converted to JPG first, and RAW formats (CR2, NEF, ARW and others) can also be converted HiCompress.
A concrete example: a 3MB phone photo resized to 1600px wide and compressed to 100KB will look clean on a laptop screen and in a phone gallery. The same photo pushed to 50KB will still be acceptable for a form upload but may show slight blockiness in dark areas.
For a second opinion on format choices and compression settings, MDN Web Docs has plain-language guidance on image formats and quality settings.
Can I use HiCompress to convert HEIC or RAW files from my camera or iPhone to JPG?
Yes. HiCompress lists both an HEIC-to-JPG converter and a RAW converter among its image tools, and both are described as batch operations, so you can queue multiple files rather than converting one at a time.
What each converter handles
| Your source file | HiCompress tool | Typical origin |
|---|---|---|
| HEIC / HEIF | HEIC to JPG | iPhone or iPad photos |
| CR2, CR3, NEF, ARW, ORF, PEF, RAF, RAW | RAW Convert | Canon, Nikon, Sony, Olympus, Pentax, Fujifilm cameras |
Both paths output JPG. RAW conversion is the more demanding case: RAW files are much larger than HEIC files, so a batch of several hundred shots will take noticeably longer to upload and process than a comparable set of phone photos.
Practical things to weigh
- Upload time is the real cost. Conversion itself is quick; moving large camera files over a home connection is not. A card full of RAW files is better split into smaller batches.
- JPG is a one-way choice for editing. Converting RAW to JPG discards the extra tonal latitude that RAW gives you in a photo editor. If you plan heavy exposure or white-balance correction, edit the RAW first and convert a copy to JPG for sharing.
- HEIC conversion is mostly about compatibility. The usual reason to convert iPhone photos is that a website, printer or older program will not open HEIC. Here the conversion is straightforward and loses little for everyday viewing.
- Check the result at full size. Open one converted file and zoom in before processing the whole batch, particularly with fine detail or high-ISO shots.
A sensible workflow
Sort your files first: send the keepers to the converter and leave the rejects on the card. Convert in batches of a few dozen, download each batch before starting the next, and keep your originals untouched so you can re-convert at different settings later.
If you also need to shrink the resulting JPGs, HiCompress has a compressor and a resize tool in the same toolkit, plus PDF tools such as JPG-to-PDF if the images are destined for a document. For a second opinion on format support, CloudConvert and ImageMagick cover similar ground, the latter as downloadable software rather than a browser tool.
How do I remove the background from multiple images at once with HiCompress?
Use HiCompress's AI Remove Background tool, which the site describes as a batch background remover: you upload multiple images, the tool removes the background from each, and you download the results. You do not need to install anything or create an account, according to the page.
A practical workflow
- Open the AI Remove Background tool under Image Tools.
- Upload your images in one batch rather than one at a time.
- Let the tool process them and review the cutouts, since edges around hair, fur or semi-transparent objects are where automatic removal usually struggles.
- Download the transparent-background results and place them on the new background in your design tool.
What to check before committing
- Edge quality: Busy or low-contrast backgrounds are harder than plain studio backdrops. Test one image first if your batch is large.
- Batch size: Very large batches can be slow or hit upload limits, so splitting into smaller groups is a sensible fallback.
- Output format: Transparent results are normally PNG or WEBP; JPG does not preserve transparency, so avoid it for cutouts.
- Rights and privacy: For client or personal photos, check whether you are comfortable uploading them to a free web service.
Alternatives worth knowing
If you need desktop-level control, GIMP handles background removal manually with layer masks. For a browser-based editor with more retouching control, Photopea is a common choice. remove.bg is a dedicated background remover, and Canva includes a background remover in its design workflow.
For most quick jobs — product photos, profile pictures, slides — HiCompress's batch tool is the fastest route. For a handful of tricky images, expect to clean up edges afterwards in an editor.
What PDF tools does HiCompress offer for merging, splitting, or converting PDFs?
HiCompress offers a small PDF toolkit alongside its image tools. Its PDF features cover three common jobs: converting images into PDFs, splitting or merging existing PDF files, and converting PDF pages back into images.
PDF tools listed on the site
| Tool | What it does | Typical use |
|---|---|---|
| JPG to PDF | Combines JPG, PNG, WEBP, or BMP files into a PDF, with adjustable orientation and margins | Turning photos, scans, or screenshots into one shareable document |
| Split PDF | Separates one page or a whole set of pages into independent PDF files | Isolating a signed page or a single chapter from a long document |
| Merge PDF | Combines or joins multiple files into one PDF | Assembling reports, receipts, or scanned batches |
| Delete Pages | Removes selected pages from a PDF | Dropping blank, duplicate, or outdated pages |
| PDF to JPG | Converts PDF pages into JPG, PNG, or WEBP images | Previewing pages or reusing them in slides and web pages |
| Extract Images | Pulls all embedded images out of a PDF | Recovering photos or graphics from a designed document |
The site also lists a Compress PDF tool for reducing PDF file size, and states that no installation or registration is required.
How to choose between them
- If your source material is images, start with JPG to PDF and set orientation and margins before generating the file.
- If one large document needs to become several smaller ones, use Split PDF; if the opposite is true, use Merge PDF.
- If you only need to fix a few unwanted pages, Delete Pages is less disruptive than splitting and rejoining.
- If you need editable or web-friendly visuals from a PDF, use PDF to JPG or Extract Images instead of converting the whole file.
A practical next step: for a scanned contract, run JPG to PDF to assemble the pages, then Compress PDF to bring the file down before emailing it. For a report where you only need one section, Split PDF followed by Delete Pages on the extracted part is usually faster than rebuilding the document.
Is HiCompress really free to use, and do I need to register or install anything?
HiCompress presents itself as free to use, with no installation or registration required. Its own pages describe an online toolkit for compressing images, converting formats, editing photos and handling PDFs, and the wording throughout is "free" rather than "free trial" or "freemium": the compressor, converter, DPI changer, resizer, cropper and PDF tools are all listed as available tools, and the site says there are "50+ tools to convert, compress, and edit images for free."
What "free" likely means in practice
- No account wall for basic tasks. The description explicitly says "no installation or registration required" for compressing a PDF, and the same pattern applies across the image tools. So for a one-off job, you can open the page, upload a file, process it and download the result.
- Browser-based, so nothing to install. Everything runs in the web app. There is no desktop program to download, which matters if you are on a locked-down work laptop or a phone.
- Batch processing is part of the free offer. The site advertises batch compression and conversion, so free use is not limited to one file at a time.
- Free does not automatically mean unlimited. The page evidence does not state file-size caps, daily limits, or whether large batches are throttled. Treat "free" as "no payment and no signup mentioned" rather than "no constraints whatsoever."
A realistic scenario
Say you have a folder of phone photos in HEIC and a scanned PDF that is too large to email. You open HiCompress, convert the HEIC files to JPG, compress the PDF, download the results, and close the tab. No account, no software, no cost. That is the core use case the site is built around.
The trade-off to keep in mind
Uploading files to any online tool means your data leaves your device and is processed on someone else's server. For holiday photos that is usually fine; for contracts, ID documents or client material, check the site's privacy and file-deletion terms first, or use offline software instead. The other consideration is that a free, ad-supported web tool can change its limits or add paid tiers later, so avoid building a workflow that depends on it staying identical.
Next step
Test it with one non-sensitive file before committing a whole batch: upload, process, download, and confirm the output quality is acceptable. If the result is good and the file is not confidential, batch the rest. If you need guaranteed confidentiality or very large volumes, an installed tool such as ImageMagick or GIMP keeps everything on your own machine.
