JPG, PNG, WebP · up to 30 files at once · stays in your browser
Lower = smaller file. 75 is a safe default for photos.
Resizing the longest edge often shrinks files dramatically.
How to compress images for free
Three steps — all inside your browser, nothing to install or sign up for.
Drop your pictures
Drag up to 30 images into the upload area, or tap to pick them from your device. JPEG, PNG, WebP and AVIF are all accepted. Or press ⌘V (Ctrl+V on Windows and Linux) to paste an image from the clipboard.
Set the quality
The default quality of 75 cuts most photos by 60–80% with no visible difference. Move the slider and check the live preview. Optionally cap the longest edge to resize at the same time.
Download — free, no watermark
Compare original and result with the before/after slider, then save files one by one or all at once. No watermark is added, no account is required, and you can come back as many times as you want.
Why this compressor is free
- No server costs
- Compression runs on your device using the browser's Canvas API — there is no upload, no cloud processing, and no per-image cost for us to pass on.
- No account wall
- Nothing is stored, so there is nothing to tie to a user account. Drop a picture, download the result, done.
- No watermark or branding
- The output is your picture and nothing else. No 'compressed with…' badge, no corner logo, no metadata injection.
- No file-size cap
- Because the file never leaves your device, there is no upload limit. A 50 MB camera original works the same as a 500 KB thumbnail.
- No daily limit
- Compress one picture or a hundred — there is no quota, no countdown, and no 'upgrade to continue' prompt.
- Works offline
- Once the page has loaded, the compressor keeps working even if you disconnect. Airplane mode, spotty Wi-Fi — it does not matter.
Frequently asked questions
- Is this image compressor really free?
- Yes. There is no paid tier, no daily limit, and no watermark. The tool runs entirely in your browser using the Canvas API, so there is no server-side cost to recoup.
- Do I need to create an account?
- No. There is no signup, no login, and no email required. Open the page, drop your pictures, and download the results.
- Are my pictures uploaded to a server?
- No. Every file is decoded, re-encoded, and downloaded entirely inside your browser. Your pictures never leave your device, and the tool keeps working if you go offline after the page has loaded.
- Is there a file-size limit?
- No. Because the file never leaves your device, there is no upload cap. The only limit is your device's available memory — in practice, even 50 MB originals process fine on a modern phone or laptop.
- Will compressing add a watermark?
- No. The output is your image and nothing else — no watermark, no logo, no metadata injection.
- How much smaller will my image get?
- A typical phone photo at the default quality of 75 shrinks by 60–90%. The exact figure depends on image content, resolution, and how heavily it was compressed before. The output size is shown live for every file.
- Can I compress multiple images at once?
- Yes. Drop up to 30 files at a time — each is compressed at your chosen quality. Use the Download All button to save every result.
- What formats are supported?
- JPEG, PNG, WebP and AVIF on input. Output is JPEG by default, or you can switch to WebP for an extra 25–35% saving at the same quality.
A compressor that costs nothing — here is why
Most "free" image compressors upload your picture to a server, process it there, and either watermark the result, cap you at five files a day, or gate the best quality behind a paywall. That model exists because server processing costs real money per image.
This tool takes a different approach. It runs entirely on the HTML5 Canvas API inside your browser: the picture is decoded, drawn to an off-screen canvas, and re-encoded at the quality you chose — all on your own device. No upload, no queue, no per-image cost.
That is why there is no paywall, no watermark, and no daily limit. There is nothing to meter.
Need a specific file-size target? Compress image to 100 KB finds the highest quality that fits. Want a format-specific tool? Compress JPEG gives you a live quality table for JPG.
Your files never leave your browser
Compression runs locally with the Canvas API. We do not store, upload, or analyse your pictures. The tool keeps working even if you disconnect from the internet after the page loads.
