FAQ
Which format should I choose?
WebP for websites (small and widely supported), JPG for sharing and printing, PNG for graphics with sharp edges or transparency, AVIF for the smallest files in modern browsers.
Are my photos uploaded?
No. Every image is decoded and re-encoded inside your browser; nothing is sent to a server.
Is there a file or batch limit?
No limits are imposed. Very large photos (over 50 megapixels) are scaled down to stay within browser memory.
