Frequently asked
Is my image uploaded anywhere?
No — compression runs entirely in your browser using a Web Worker. The image never leaves your device.
What's the largest image it can handle?
No hard cap — very large images (e.g. 20MB+ camera photos) may just take a few seconds longer, limited by your device's own memory.
