PDF Sealer

PDF Sealer helps you add seals, stamps and approval marks to PDF files. PDF Sealer supports image and text seals, lets you position and scale seals on specific pages, and saves a new sealed PDF for sharing.

Key features

• Image and text seals — import a stamp image or type text to create a reusable seal.
• Precise placement — move, rotate and resize seals and set opacity before applying.
• Batch processing — apply the same seal to multiple pages or multiple documents.
• Preview and export — review seals before saving and export the sealed PDF for sharing or storage.

How it works

Open a PDF, choose or create a seal, adjust appearance and target pages, then apply the seal. PDF Sealer keeps the original file unchanged and generates a sealed copy so you can retain both versions.

PDF Sealer applies seals locally by default and does not upload documents without explicit permission. Use the app to mark approvals, certify documents, or add visual stamps where needed.
