Signature Resize

Trim the blank paper, fit the signature in a small box, and keep the JPG under the KB cap the form asks for.

Signature uploads

What does this change?

Blank edges around the ink are cut away. The signature is then centered on a white background at 140×60, 200×80, or 300×120 pixels, and saved as JPG under 10, 20, 30, or 50 KB. Trim only keeps the cropped signature at its own size and only shrinks it if the KB cap needs it.

Why is the background white?

JPG cannot store transparency. A white sheet is what most exam and government forms expect, and it stays much smaller than a PNG of the same signature.

The form wants a photo under 20KB, not a signature.

Use Resize Image to 20KB for a portrait or ID photo. This page is for a handwritten signature.
