By ImgHeal · Updated
Check full filenames and actual file type when a converted or downloaded image has a confusing suffix such as photo.jpg.png.

Show the complete filename
Use your operating system's normal file-information controls to view extensions and the reported type. A shortened display can hide the final suffix. Record the actual name before changing it. Similar icons or a sender's label are not enough to establish which decoder an upload service will need.
Distinguish naming from encoding
Open the image in a suitable viewer and check whether its contents match the final extension. A valid PNG named with an extra JPG segment may simply have an awkward name. A webpage or unsupported file remains that content regardless of its suffix. Do not rename a file as a substitute for an actual conversion.
Create a clear working copy
If necessary, export through software that supports the source format and save a simply named upload copy. Verify dimensions and appearance afterward. Keep the original and its original name in the source records. A clean filename should make selection easier while preserving the relationship to the exact file used for restoration.
Check before finishing
- The full final suffix is visible.
- The actual content type is understood.
- Any export is verified and traceable.
