Why do transparent AVIF images look black when converted to JPG in some tools?

Because JPEG lacks an alpha channel, unhandled transparent pixels often default to black (#000000). Doczing paints a clean white background (#FFFFFF) before drawing the image, preventing black silhouettes.

What is the recommended JPEG quality setting?

A setting between 85% and 92% provides near-lossless visual quality while keeping file size modest for web or social sharing.

Can I convert photos taken on my Android or iPhone?

Yes. Modern mobile browsers support AVIF decoding natively, allowing you to convert photos directly from your phone gallery.

Does this tool save a copy of my converted files?

No. Converted files are held solely in temporary browser memory and are deleted automatically when you refresh or close the page.
