Everything you need to know
Traditional image compressors upload your files to a server, process them, and send them back. That means waiting, bandwidth costs, and privacy risk. This tool decodes, resizes, and re-encodes images instantly — with zero upload and it works offline after page load.
For web photos: aim for 70–80% quality — that typically cuts file size in half with no visible difference. For hero banners: 80–85% quality and resize to the max display width (usually 1920px). For thumbnails and avatars: 60–70% quality, resize to 2× the display size for retina screens. For screenshots with text: keep quality higher (85–90%) or convert to PNG for crispness.
JPG is best for photographs — small file sizes, no transparency. PNG is best for graphics, logos, and screenshots with transparency or sharp edges — larger but lossless. WebP beats both by 25–35% on average, and is supported by every modern browser. If you're building a modern website, WebP should be your default output format.
Because everything runs on your device, the tool works fully offline after the first visit. There are no rate limits, no account requirements, and no data retention. Files are held in memory only and released the moment you close the tab. This also means compression speed is limited by your device — a modern laptop handles 50 images per minute; phones are slower but still usable for small batches.
