How to Prepare a Flawless 15 KB Signature
Sign on Pure White Paper with Dark Ink
Use a black gel or ballpoint pen on plain, unlined printer paper. Ruled lines or yellow paper degrade compression and look muddy at 15 KB.
Take Photo in Direct Overhead Light
Avoid casting hand shadows over the signature. Good illumination makes the background pure white, which compresses to almost zero bytes.
Crop Tightly Around the Signature Bounds
Crop out 90% of the blank border. Leave only 2–3 millimeters around the signature strokes before uploading to the resizer.
