Convert JPG files directly into JPG in your browser. 100% private WebAssembly processing, no uploads required.
Output format
JPG files are processed locally in your browser. They never leave your device, which makes this safe for sensitive images and screenshots.
After each conversion you see the actual output size and the exact percentage saved — never an estimate. If the optimized file is larger than the original, we say so.
Drop in dozens of JPG files at once, set a quality level, and click Convert All. Each file shows its own progress, status, and result.
A simple slider trades file size against visual fidelity. For most photos 80–85 is a sweet spot; for screenshots 90+ preserves text crispness.
The tool re-encodes your JPG file with a more efficient setting, stripping redundant metadata and applying tighter compression without visibly changing the image. The result is a smaller file with the same content.
No. Files are processed locally in your browser. They are never sent to a server.
Yes. Drag in as many files as you want, click Convert All, then download the results individually or as a single ZIP.
For most photos, 80–85 is a good balance. For screenshots with text, use 90 or higher. PNG and other lossless formats ignore the quality slider.
Yes. The interface is touch-friendly and runs on modern mobile browsers, though very large images may take longer on lower-end devices.
