Common questions
Why crop before resizing?
Blank margins reduce the visible signature area and waste file size. Cropping first improves alignment and compression.
Will cropping reduce quality?
No. Cropping removes unused image area without redrawing the handwriting.
Can I crop on mobile?
Yes. The crop editor supports touch controls.
