Don't guess how your image looks. Compare the uncompressed original and the compressed version side-by-side in real-time with an interactive slider and up to 4x zoom magnification.
Batch Processing & ZIP
Drop dozens of images at once. Apply uniform compression or target a maximum file size in KB. Export all optimized assets in a single, neat `.zip` bundle with one click.
Frequently Asked Questions
Everything you need to know about JPEG compression and privacy.
Will my image quality suffer during compression?
JPEG is a lossy compression format, but quality levels between 75% and 90% typically strip imperceptible high-frequency noise while slashing file sizes by 60% to 85%. You can inspect the fidelity directly using the split slider.
Are my photos uploaded to any server?
Never. All canvas rendering, color sampling, and file packaging occur inside your browser using the HTML5 Canvas API and WebAssembly. Your photos never leave your device.
How does the "Target File Size" feature work?
When you enter a target size (e.g. 250 KB), an intelligent binary search runs up to 5 quick compression passes to find the exact quality setting that matches your quota while retaining maximal clarity.
Can I convert PNG or WebP images to JPG?
Yes! You can drop PNG and WebP files into the compressor, and SqueezeJPG will composite them onto a clean canvas and export them as lightweight, web-optimized JPEGs or WebPs.
Does SqueezeJPG work on iPhone and Android?
Absolutely. SqueezeJPG is fully optimized for iOS Safari (iPhone / iPad) and Android Chrome. You can compress photos directly from your Camera Roll or Gallery, and save them straight back to your device without uploading anything.
