Select imagesFrequently Asked Questions
Is the image compressor really free?
Yes. The Image Compressor is completely free with no sign-up, no subscription and no hidden limits.
Are my images uploaded to a server?
No. All compression runs locally in your browser using the Canvas API. Your images never leave your device.
Which formats are supported?
JPG, JPEG, PNG and WebP images can all be compressed.
How does PNG compression work?
PNG is a lossless format, so the quality slider re-encodes the image through canvas and proportionally reduces dimensions to genuinely shrink the file size.
Can I compress multiple images at once?
Yes. Upload several images and compress them all with the same quality setting, then download each one or download them all together.
