Image Compressor
This free image compressor tool re-encodes your photo to WebP or JPEG at the quality you choose, cutting the file size while keeping it looking good. Drop or paste an image and it processes entirely on your device, so nothing is uploaded.
How to use Image Compressor
- 1 Drop an image on the box, click to browse, or paste one with Ctrl/Cmd V.
- 2 Choose an output format — WebP for the smallest file, or JPEG.
- 3 Drag the Quality slider (10-100%) to trade size against sharpness.
- 4 Click Compress, then download the result and compare it to the original size.
Frequently asked questions
Is my image uploaded to a server?
No. The image is decoded and re-encoded locally in your browser using a canvas. It never leaves your device, so private photos and screenshots stay private.
Should I pick WebP or JPEG?
WebP usually produces a noticeably smaller file at the same quality and is widely supported. Choose JPEG if you need maximum compatibility with older software.
How much should I lower the quality?
Around 75% is a good balance for photos. Lower it further for bigger savings, or raise it toward 100% if you start seeing blur or blockiness.
Does compressing change the image dimensions?
No. This tool re-encodes at the same resolution to reduce file size; it doesn't resize the picture.
