Image Compressor
Compress JPG, PNG or WebP images with adjustable quality and optional resizing before download.
Your images stay in your browser. Files are never uploaded to a server.
Re-encoding through Canvas removes embedded metadata. PNG export is lossless, so the quality control applies only to JPG and WebP.

How image compression works
JPG and WebP reduce file size by discarding visual detail that is difficult to notice. Lower quality produces a smaller file. PNG is lossless: re-encoding can remove metadata but its quality is not controlled by a slider.
Choosing a format
- JPG: photographs and complex imagery without transparency.
- PNG: logos, screenshots and transparent graphics.
- WebP: modern web delivery with strong compression and transparency support.
FAQ
Does resizing preserve the aspect ratio?
Yes. Maximum dimensions constrain the image without stretching it.
Are metadata and location removed?
Canvas creates a new image from pixels, so EXIF and location metadata are not copied to the output.
