PNG to JPG: prepare a screenshot for a photo-oriented upload form

Use PNG to JPG to prepare a screenshot for a photo-oriented upload form. Start with the original file rather than a copy that has already been exported several times. The aim is a usable working version for the receiving application, with the source still available for a meaningful comparison.

How to use PNG to JPG

1. Select one PNG file in the image field.
2. Enter quality from 1 to 100, then submit the form.
3. Inspect the preview, download the result, and test it in the destination application.

A source-to-destination example

Try a help-center screenshot containing dark text on white. Compare letter edges after export and open the file in the upload form before replacing the original.

What needs verification

Check small lettering and any transparent edges against the original. A format change cannot restore detail missing from the source. The implementation requests image/jpg rather than image/jpeg. A browser may therefore return PNG data despite the .jpg filename. Verify the actual format. JPEG also cannot retain transparent pixels.

Common questions

Should I use an existing screenshot or take a new one?

Start with the clearest original available. Exporting cannot correct unreadable labels or clipped edges.

Is the JPG filename enough for an upload?

No. Confirm the MIME type or open the result in an editor, since the current encoder request may produce PNG.
