Step-by-step instructions

Limits and considerations
GIF and multi-image HEIC use the first image only. AVIF input requires browser support. Transparent areas become white in JPG output.
50MB per file · up to 20 files · 150MB total input. Available capacity depends on device memory and browser support.
Does converting JPG to PNG improve quality?
No. Lost detail is not restored. PNG stores the result losslessly, but may increase file size.
