JPG Compressor
Compress JPG/JPEG files locally with quality-aware re-encoding. No upload, no watermark, free. Reduce file size 50-80% in seconds.
Recommended export settings
Need to compress JPG files? JPEG (Joint Photographic Experts Group) is the most common image format on the web — universally supported by every browser, phone, social platform, and email client. Despite this universality, JPG files are often poorly encoded and dramatically oversized. Phone cameras default to high quality (90+) to preserve detail; stock photo sites export at maximum quality; image editors like Photoshop default to q100 'for safety'. This JPG compressor re-encodes to a smarter quality setting (default q80) producing dramatically smaller files with no visible quality loss on most screens.
- 1JPG is universal but often poorly encoded at the source — re-compression with smart quality yields 50-80% size reduction with no visible quality loss.
- 2Phone-recorded JPGs easily hit 3-5 MB, blowing past email attachments, WhatsApp Status (100 KB), and Discord free-tier limits. Compression is essential for sharing.
- 3Local processing avoids uploading personal photos, family images, and confidential business content to unknown third-party servers.
- 4Free, no account, no watermark, no daily limit — compress as many JPGs as you need. The tool uses the browser's native Canvas API; there's no server cost to pass on.
- 5JPEG quality 80 is the sweet spot where 95% of viewers can't tell the difference from the source. Quality 90+ is visually lossless but produces files 2-3× larger.
- 6Quality-aware binary search: if you set a target file size (e.g. 500 KB), the engine iterates quality to hit it precisely.

Frequently asked questions
Typically 50-80% size reduction with no visible quality loss at quality 80. Heavily compressed sources (already q50+) won't shrink much further; lightly compressed sources like phone photos, stock photos, and Photoshop exports shrink dramatically — often 70-90% reduction. The exact ratio depends on content: clean photos compress better than noisy low-light shots.
