Think of the photograph as identity data with a visual presentation layer. The picture must remain recognisable while the technical delivery matches the receiving system.
Work from hard limits to soft judgments
File size and dimensions can usually be checked numerically. Face position, lighting and background need a visual review against the official examples.
Keep a copy of the version that failed
When troubleshooting, do not overwrite the previous file immediately. A simple filename such as passport-original.jpg, passport-size-fixed.jpg and passport-upload-version.jpg makes the workflow auditable and prevents accidental loss of the original.
Do not let the editor hide the problem
Zoom in and inspect the exported image itself. A crop boundary, background halo or compression artefact can disappear in a small preview and become obvious after upload or print.
What can quietly go wrong
An exported image can change during resizing, compression or printing even when the preview looked fine. Inspect the saved output itself before submitting it.
Practical detail to carry forward
When you are done, open the final file once more from disk rather than from the editor. That confirms the exported file—not just the preview—contains the intended crop and dimensions.
