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.
