Frequently asked questions
Is there a file-size limit?
Only your device memory — files never leave the browser.
Does resizing reduce quality?
Downscaling uses high-quality smoothing; JPEG re-encoding at 92% keeps artifacts minimal.
Can I upscale?
Yes, but enlargement cannot recover detail — output will be softer.
