Lossy vs Lossless Compression for Visa Application Forms
Image compression comes in two flavours. Visa portals commonly list strict size and dimension rules for photos and scans, so check the exact numbers on the form you are using.
Recommended settings for visa application forms
| 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 visa application forms, lossy is the practical choice. Save lossless formats for graphics where every pixel edge matters.
