Upload a clear signature on a light background. The cutoff identifies non-white ink and finds its outer bounding rectangle, excluding empty margins.

How it works

Upload a clear signature on a light background. The cutoff identifies non-white ink and finds its outer bounding rectangle, excluding empty margins.

Choose the right inputs

The trimmed rectangle is fitted into the requested pixel canvas with white padding. Proportions remain intact rather than stretching a short signature vertically.

Understand the output

JPEG quality is searched against the maximum byte limit while keeping the exact output dimensions. If no acceptable encoding fits, the operation requests a smaller canvas or a larger limit.

Use the result carefully

The maximum uses decimal kilobytes, with one KB equal to 1000 bytes. Always compare the exported file with the target form’s exact dimension and size rules.

Trims near-white outer margins and fits the ink without distortion. A strict byte limit may require smaller dimensions.
A 300 × 100 output requested under 20 KB retains those dimensions and downloads only if its JPG is at most 20,000 bytes.
