Making a clean PDF look like a desk scan (for picky upload portals)

When a government or bank portal rejects 'too perfect' PDFs and wants something that looks scanned.

Some upload portals flag digitally-born PDFs as 'unsupported.' Same content, different rejection. Scan Studio adds paper grain, slight rotation, and edge wear so the file reads like it came off a flatbed.

Don't overcook it

Heavy aging looks fake on a two-page bank letter. Light grain + micro rotation is enough for most portals. Preview at 100% zoom — if text looks muddy, reduce the effect.

Export PDF if the portal requires PDF; PNG for image-only forms
Match page size to the original (A4 vs Letter)
Keep an unmodified copy for your records

Everything processes locally, which matters when the source document has account numbers you would not email to a stranger.
