Lossy vs Lossless Compression for Passport Photo Uploads
Image compression comes in two flavours. Online photo uploads for official documents usually state a maximum file size and pixel range, and files outside it get rejected.
Recommended settings for passport photo uploads
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 600 px on the long edge |
| Quality | 70 |
| File size | 100 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Lossy vs Lossless Compression
Lossless compression, as in PNG, keeps every pixel exactly and saves modest space. Lossy compression, as in JPEG and WebP, discards detail the eye barely notices and saves far more.
For photographs used for passport photo uploads, lossy is the practical choice. Save lossless formats for graphics where every pixel edge matters.
