Compress JPG
Compress JPG without uploading it
Drop a JPG and pick a quality level (1-100%) and optionally cap the width. This page re-encodes it on a canvas at the quality you choose. No library, no server, no upload - the image is read on this page and is never uploaded. Honest limits: JPEG re-encoding is lossy, quality below 50% leaves visible artifacts, and capping the width shrinks the file far more than quality alone.
- JPEG re-encoding is lossy - compressing an already-compressed JPG adds another layer of quality loss each time.
- Quality 70 to 85% suits photos; 95%+ grows the file for almost no visible gain; below 50% leaves blocky artifacts.
- Capping the width shrinks the JPG far more than nudging quality down - use it when the file must be small.
- Photos with heavy detail (foliage, text, noise) compress worse than smooth images.
- JPEG has no transparency - any transparent pixels are painted onto a white background.
- Animated GIF or WebP files keep only the first frame in the output.
- 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 quality and compress again.
- The output is always re-encoded as JPEG regardless of the source format - this tool is for shrinking JPGs.
