Frequently Asked Questions
How does browser compression work without uploading files?
We use the browser HTML5 Canvas API and WebAssembly compression algorithms. Your computer processor does all the work locally.
Which format offers the best compression?
WebP generally produces 30% to 50% smaller files than standard JPG and PNG with identical visual quality.
How much smaller will my image get?
It depends on the original. Photos usually shrink a lot with no visible change, because the tool removes data the eye does not notice.
Will compression damage my image?
No. The tool re-encodes the picture intelligently and previews the result, so you can compare before downloading.
