Image Compressor
Make photos smaller in KB for uploads and forms by lowering JPEG or WebP quality, with a before/after size.
Your photo stays on your device. Nothing is uploaded.
How it works
The image is re-encoded at the quality you choose. Lower quality gives smaller files. If the result would be bigger than the original, the tool tells you instead of making it worse. PNG screenshots often shrink most as WebP.
Frequently asked questions
How do I get under 100 KB?
Lower the quality and, if needed, resize the image first with the Image Resizer.
