Check the stated requirement
Note the maximum file size, accepted formats, and minimum dimensions before editing. Identity documents and receipts need readable text; application photos may have a required aspect ratio or pixel size.
Resize before compressing heavily
Camera photos are much larger than most email and form previews require. Reducing width and height can cut file size substantially. Then lower WebP or JPG quality gradually until the result fits the limit.
Verify the downloaded file
Open the finished image and zoom into names, numbers, signatures, or facial details. Confirm its extension is accepted and leave some margin below the upload limit because systems can calculate size differently. Keep the original until submission succeeds.
