Steps to verify
- Generate the file with conversion.
- Reopen the download.
- Check destination format recognition.
How to interpret the result
URLTO creates output in the browser and checks requested type against actual MIME. It does not mark unsupported conversion successful by renaming.
Deciding what to do next
Confusing old and new downloads can lead to the wrong upload. Check output name, content and format together.
Feature scope
Re-encode supported PNG, JPEG and WebP in the browser. JPEG fills transparency with white; review actual output support without assuming original metadata or animation is retained.
