How to compress images online
Big image files slow down websites, eat up phone storage and make emails harder to send. Our free image compressor shrinks JPG, PNG and WebP files down to a fraction of their original size — usually 60–80% smaller — while keeping the photo looking the same to your eye.
To compress an image, just drop it onto the area above (or tap "Choose Files"). Pick a quality level — 80% is a great default — and we'll process every file instantly in your browser. You'll see the original vs. compressed file size for each photo, then download them one at a time or all together in a ZIP.
Why compress images?
- Faster websites. Smaller images load quicker and rank better on Google.
- Email-friendly. Many inboxes reject attachments over 10 MB — compression fixes that.
- Save storage. Free up space on your phone, laptop or cloud drive.
- Cheaper bandwidth. Less data used when sharing or hosting images.
Is it really private?
Yes. The compressor runs entirely in your browser using the Canvas API. Your photos are never sent to our servers — they don't leave your device. You can even disconnect from the internet after the page loads, and it will still work.
