Frequently asked questions
Common problems and fixes
- My signature or drawing looks faint
Why: thin pen input or fast strokes produce low-contrast ink on small canvases.
Fix: draw larger than needed, use a thicker stroke, or type a signature and pick a heavier font style.
- My changes seem to have disappeared
Why: the original file was opened instead of the new download — the tool never modifies your original on disk.
Fix: look for the freshly downloaded file and use that as your new version.
- Added text does not match the document font
Why: embedded subset fonts cannot always be reproduced, so the closest standard font is offered.
Fix: pick the nearest match from the font options, or accept a slight typeface difference.
