The signature clean-up is on: it makes grey paper white and the ink dark, without tracing or redrawing anything. Bindery then writes the JPG at exactly 140 × 60 pixels at the best quality under 20 KB — and because a small, mostly white picture is often under 10 KB, it brings the file up to the minimum with an empty comment block, leaving the picture unchanged. Change the numbers if your form states others. Nothing is uploaded.
How it works
- Sign on white paper, photograph it and choose the photo — the signature rule is already chosen
- Frame the signature so it fills the box
- Make the JPG and download it
Questions people ask
Why was my signature file too small before?
A 140 × 60 picture that is mostly white compresses to a few kilobytes, below the 10 KB many forms require. Bindery keeps the best quality and adds an empty comment block inside the JPG until it reaches the minimum — the form sees a larger file with exactly the same picture.
Should I sign in blue or black ink?
Follow your form’s instructions; many ask for black or dark blue. The clean-up makes the paper white and the ink dark gray to black, whatever colour you used.
Is my signature uploaded anywhere?
No. The clean-up, resizing and size search run in your browser tab, and the signature never leaves your device.
