Why bank KYC systems restrict signature size
Banks store millions of customer records. KYC (Know Your Customer) regulations require signature images to be stored alongside identity documents — and banks enforce strict file size limits, typically 10–50 KB, to keep document databases manageable and efficient for back-office review systems.
The size limits also ensure digital signatures display correctly within standard form field dimensions. A large signature file does not display more legibly in a form — it just wastes storage and slows down the customer onboarding database.

Tips for bank signature uploads
- White background, dark ink — bank portals display signatures on white form fields. Dark blue or black ink on white paper gives the cleanest result.
- Crop tightly — remove excess white space around your signature. Tight cropping keeps the signature large and legible even at small file sizes.
- 300×80 pixels is a common requirement — many bank forms specify exactly these dimensions. Use the tool's width and height fields to set them precisely.
- JPG for size control — for very small targets like 10–20 KB, JPG gives more reliable file size control than PNG.
