Frequently asked questions
Is my image uploaded to a server?
No. Compression runs 100% in your browser using the Canvas API. Your file never leaves your device.
Will compression reduce quality?
JPEG and WebP are lossy formats, so lower quality numbers mean smaller files with slightly less detail. PNG stays lossless but still gets optimized. The before/after sizes are shown so you can decide.
Is there a file size limit?
Only your device memory limits it. Large photos are handled locally, so even 20–30 MB images work.
Can I convert PNG to JPG?
Yes — choose JPG or WebP as the output format to convert while compressing.
