Quick answer
For example, use Android photos for sharing/archiving: back up, export to the target format and spot-check 2-3 files. Android photos are often JPG/HEIC/WebP, and camera apps vary widely.
Why it matters
Real scenarios expose problems better than abstract specs.
Check the real format, not just the extension.
Step by step
- Back up the original; never overwrite the only copy.
- Confirm the target platform's format, dimensions and size limit.
- Cap the longest side first, then quality; change one variable at a time.
- Compare size and sharpness after compressing, and step back one setting if needed.
- Keep the original until the output is confirmed.
Common mistakes
- Chasing the smallest file and blurring text/edges.
- Converting transparent PNG to JPEG, turning transparency white or black.
- Recompressing the same file and accumulating loss.
- Overwriting the original, so a bad result cannot be undone.
Checklist
- Original backed up.
- Output format/dimensions/size meet the platform.
- Text is readable and transparency is correct.
- Verified in the real page/email/upload field.
- Original kept until confirmed.
Key facts
- Check the real format, not just the extension.
- Some devices support HEIF, which may not work on the web.
