Image Compressor
Shrink JPG, PNG and WebP images without uploading them.
100% private: your image is processed inside your browser and is never uploaded to any server.
About the Image Compressor
The Image Compressor reduces the file size of your photos and graphics by re-encoding them at a quality you control. Lower the quality slider to squeeze JPG or WebP files down dramatically while keeping them sharp enough for the web. Smaller images load faster, save bandwidth and improve your page speed scores. Crucially, the whole process happens inside your browser — your image is never sent to a server.
How to use it
- Select an image from your device.
- Pick JPG or WebP and drag the quality slider until the size looks right.
- Download the compressed image with one click.
Frequently asked questions
Is my image uploaded anywhere?
No. The image is read and re-encoded locally using the HTML canvas. It never leaves your browser, so it is completely private.
JPG or WebP — which is smaller?
WebP usually produces smaller files than JPG at the same visual quality, but JPG has wider compatibility with older software.
Why is there no reduction sometimes?
If the original is already heavily compressed, re-encoding at high quality can match or exceed its size. Lower the quality to save more.
