Common mistakes to avoid
- A 1:1 or 3:4 photo — GDS strictly requires the 4:5 ratio
- A file outside 30–100 KB; both too small and too large are rejected
- Uploading a typed or digital signature instead of a pen-and-paper one
Pro tips
- Target 50–80 KB for the photo — inside both the floor and ceiling
- Certificates go in as separate 720×1024 JPGs under 200 KB, one per document
- Keep file names simple with no special characters — the portal is picky
