Some older Indian portals, especially for signatures, thumb impressions and small ID photos, still allow only 10 KB or ranges like 4–12 KB or 5–10 KB. Railway, postal and some state recruitment forms have used limits like these. At 10 KB there’s no room for wasted pixels, so the trick is the right size more than the right quality.
| Image | Size that fits comfortably |
|---|---|
| Signature (black on white) | 140 × 60 to 300 × 100 px |
| Face photo | Around 100 × 120 to 160 × 200 px |
| Thumb impression | Around 150 × 150 px |
| Full phone photo | No: it must be made much smaller |
For very large or noisy images, even the smallest sensible version might be over 10 KB. The studio tells you the smallest size it could reach rather than handing you a broken file. Crop more tightly, or type a smaller size in the optional exact pixels boxes under KB size, then try again.
Everything runs in your browser, so ID documents never leave your device.
Portals differ: some count 1 KB as 1,000 bytes, others as 1,024. A file of 10,100 bytes passes the second rule but fails the first. We always aim for 10,000 bytes or less, so the file passes either way. The badge shows the exact number of bytes, so you can compare it with what the form says before you upload.
Yes, by making it smaller in pixels and using efficient JPG compression. A passport-size face photo or a signature fits easily.
Signatures stay crisp. Photos look fine at small sizes like 100×120 px, which is what 10 KB portals expect.
We aim just under 10 KB, which is inside that range for normal photos and signatures.
Some portals count it that way. We use 10,000 bytes, which is stricter, so the file passes both.
