About signature uploads
Application forms usually want a signature as a small, wide image — 140 × 60 pixels is the most commonly specified box — and under 10 to 20 KB. Both numbers are easy once the image is mostly signature and not paper.
The trick is cropping before resizing. A photo of a whole sheet of paper, squeezed into 140 × 60, leaves the signature as a few unreadable strokes. Crop tightly around the ink first, then resize, and the signature fills the box properly.
Signatures compress extremely well because they're mostly flat white with thin dark lines. Once the dimensions are right, reaching 20 KB is straightforward with no visible loss.

Questions, answered
My signature looks faint after resizing — why?
Thin pen strokes lose weight at small sizes. Sign with a thicker pen, crop close so the signature fills the frame, and photograph it in even light with no shadow.
Should it be JPG or PNG?
Follow the form. JPG is the usual requirement; PNG keeps the lines crisper but produces a larger file, which matters at a 20 KB cap.
Can I remove the paper background?
For a plain white sheet, the transparent background tool can lift the white away — though most forms expect a plain white background rather than transparency.
Are my photos uploaded?
No. Resizing happens in your browser, so ID photos and documents never leave your device.
