Prepare a signature for an upload form
Crop unnecessary space with the drag handles, set output dimensions and check the encoded result before downloading. Target-size output uses JPEG and may reduce dimensions to meet the size limit; it does not preserve transparency. Keep the original signature and verify the receiving form’s size, format and dimension requirements.

Frequently asked questions
Can the tool create a legally verified signature?
No. It resizes an image you supply. Very small file limits can reduce dimensions or make fine strokes less legible.
Is my content sent to a server?
No. Processing runs inside your browser. Optional editor recovery saves a draft on this device only. Read the privacy policy.
Will my original file be changed?
No. Downloaded results are separate copies. Open the finished output before sharing it or deleting an original.
