Image Compression FAQ
Why does PNG export as WebP here?
WebP usually delivers smaller files than PNG while preserving strong visual quality, so this tool converts PNG to WebP for better compression.
Does this route upload the image?
No. The current compression flow runs in your browser and keeps the file on your device during processing.

The current single-file limit on this public compressor is 20MB.
