How to use the Image Compressor
- Drop your images into the box (or click to choose them).
- Adjust the quality slider — 70–80% keeps images looking sharp.
- Optionally pick WebP for the smallest files or set a max width.
- Download each image or click “Download all”.
About this tool
Large images slow down websites, fill up email attachments and get rejected by upload forms. This free image compressor re-encodes your photos with smart quality settings so they become much smaller while looking almost identical.
Everything happens inside your browser using the HTML5 canvas, so your photos are never uploaded to any server. That makes it fast and completely private — ideal for personal photos, ID scans and product images.
Tips for the best results
- For websites, a width of 1600–1920px is usually enough.
- WebP files are 25–35% smaller than JPG at the same quality and work in every modern browser.
- PNG screenshots with text compress best when converted to WebP.
Frequently asked questions
Is this image compressor free?
Yes. It is 100% free with no limits, watermarks or sign-up.
Are my images uploaded?
No. Compression runs locally in your browser, so your files never leave your device.
How much smaller will my images get?
Typical photos shrink by 50–80%. Images that are already heavily compressed may shrink less.
Will compression reduce quality?
At 70–80% quality the difference is usually invisible to the eye. You can raise the slider for maximum quality.
