Steps to verify
- Retain the original.
- Label variant purposes.
- Record the chosen output and settings.
How to interpret the result
New exports do not imply preservation of metadata or animation. Keep sources requiring those properties separately.
Deciding what to do next
Browser processing creates new results without uploading the source. Reopen downloads to distinguish old and new copies.
Feature scope
Export a new file at the same dimensions in the browser. Compare JPEG/WebP quality and format; PNG quality behaves differently and the output is not always smaller.
Frequently asked questions
