Before you convert
Check transparency, edge sharpness, colors, orientation, and whether the output opens in the app or upload form you plan to use. Keep the original HTM file until the converted PGM file has been reviewed successfully.
Common upload errors this can fix

HTM vs PGM
HTM is commonly used for web pages, browser-readable documents, and structured text exports. PGM is commonly used for general file conversion workflows.

Conversion checklist
After converting, open the PGM file before deleting the original HTM. Check file size, readability, playback or preview behavior, and whether the converted file works in the exact app, website, or device where you plan to use it.
