About this tool
Two modes. Pick a quality level yourself, or enter a target size in KB and the tool binary-searches for the highest quality that fits under it, shrinking dimensions only when quality alone isn't enough. That second mode is built for upload forms with strict size limits.
Compress one photo or a whole batch with the same settings; multiple results download as a zip. Your images are processed by your own browser and never leave your device.
How it works
- Drop one or more images, they stay on your device.
- Pick your options and convert.
- Download the result; multiple files arrive as a single zip.
