The contract is signed. Internal records want a clear 'APPROVED' stamp on the cover page so anyone opening the file knows its status. A handwritten 'approved' note doesn't communicate as well.
Stamp annotations are the right tool. Flint supports them.
Pick a preset or upload your own
Open annotate PDF, select the stamp tool. Choose from presets: 'Approved', 'Draft', 'Confidential', 'Reviewed', 'Final'. Or upload a custom stamp image (company seal, signature stamp, custom mark). Click on the page where you want it placed. Drag to resize.
Position and rotation
Stamps go anywhere — cover page corner is conventional, but margin or full-page-diagonal works too. Rotate for the classic angled-stamp look. The visible orientation suggests authority: straight stamps look formal; angled stamps look like they were applied with a physical stamp pad.
Apply across multiple pages
For a 'Confidential' stamp on every page, select all pages and apply. Each page gets the same stamp in the same position. Useful for legal documents where every page needs status indication.
When to use a stamp vs a watermark
Stamps are annotations — recipient can see them but they're separate from page content. Watermarks are part of the page content — they print, they survive flattening, they can't be casually removed. For status indication, stamps are usually fine. For protection against alteration, watermark via edit PDF.
FAQ
Can I create a custom stamp?
Yes — upload an image (PNG, JPG) and Flint converts it to a reusable stamp.
Do stamps print?
Yes by default. Toggle 'don't print annotations' to skip.
Are stamps legally binding?
Stamps are visual indicators. Legal authority depends on what the stamp represents (corporate seal, notary stamp). The annotation is decorative; underlying authority is a legal question.
