Reduce Image Size in kb
Reduce image size in KB
Drop an image and pick any target from 5 to 8192 KB. This page re-encodes it on a canvas as JPEG until it fits - quality drops first, then pixels scale down. No library, no server, no upload - the image is read on this page and is never uploaded. Honest limits: compression is lossy, very small targets cost visible detail, and if even the lowest quality cannot reach the target the closest result is returned and labeled as such.
- Pick a target that matches where the image will be used - 50 KB for forms, 200 KB for web pages, 1 MB for sharing.
- Compression re-encodes the image as JPEG - some quality loss is unavoidable when shrinking a file this way.
- The tool lowers quality first, then scales the pixels down - both steps trade detail for a smaller file.
- If even the lowest quality cannot reach the target, the closest result is returned and labeled honestly instead of claiming success.
- Photos with heavy detail (foliage, text, noise) compress worse than smooth images at the same target.
- PNG transparency is painted white because JPEG has no alpha channel.
- Animated GIF or WebP files keep only the first frame in the download.
- HEIC needs a browser HEIC codec - Safari 17+ and iOS can decode it; Chrome and Firefox usually cannot.
- The image is read on this page and never uploaded - compression runs entirely in this browser tab.
- Your original file is not modified - the download is always a new JPEG file.
- Check the result before downloading - if it looks too rough, raise the target and compress again.
