Frequently Asked Questions
Everything you need to know about formats, browser privacy, and file handling.
What is the difference between a PDF watermark and a PDF stamp?▼
A watermark is typically a large, diagonal, semi-transparent text or logo displayed across the entire page body. A stamp is a localized, opaque mark placed in a specific corner or margin (like 'PAID', 'APPROVED', an official notary seal, or a signature).
Can I add standard business stamps like 'APPROVED', 'PAID', or 'VOID'?▼
Yes. Our tool provides a library of pre-designed corporate stamps including 'PAID', 'APPROVED', 'REVISED', 'DRAFT', 'CONFIDENTIAL', and 'VOID' in standard red, blue, and green border styles.
How do I upload and apply custom signature or company seal stamps?▼
Click 'Upload Custom Stamp' to upload a transparent PNG or SVG of your handwritten signature, corporate seal, or official rubber stamp, and position it directly onto your document.
Can I specify the exact page number and coordinates (X, Y position) for the stamp?▼
Yes. You can visually drag and position the stamp on any page thumbnail or enter precise millimeter/pixel coordinates to place the stamp exactly above the signature line.
Can I resize, rotate, and adjust the transparency of my stamp?▼
Yes. Interactive bounding boxes let you scale the stamp proportionally, rotate it to mimic a genuine rubber stamp impression, and adjust opacity to blend naturally with document ink.
Will a stamped PDF be legally recognized for contracts and invoices?▼
In most jurisdictions, visual rubber stamps and signature marks serve as valid commercial consent and invoice processing markers. For legal filings requiring cryptographic non-repudiation, apply a digital certificate afterward.
Can I stamp multiple pages or batch stamp multiple documents?▼
Yes. You can choose to apply the stamp to 'Current Page Only', 'All Pages', or a defined custom page range (like 'Page 1 and Page 12').
What image formats are supported for custom stamps (PNG, SVG, JPG)?▼
We support transparent PNGs (recommended for clean rubber stamp borders), scalable vector SVGs, and standard JPGs. Transparent PNG ensures no white box obscures text behind the stamp.
Does stamping flatten the document or can the stamp be selected?▼
You can choose to leave the stamp as an editable PDF annotation or permanently flatten it into the page graphics layer using our Flatten tool to prevent modification.
Are stamped files stored on your server after processing?▼
No. Your documents and uploaded stamp graphics are deleted permanently from server memory as soon as you finish downloading the stamped document.
