## About

PDF SealBox offers browser-based tools for adding visible stamps and cross-page seals, page numbers and watermarks, converting images to PDF, splitting PDFs, and exporting PDF pages as images. Choose pages and settings, preview the result, then download a separate file. The browser tools process files locally when supported, and the source file is not overwritten. A visible stamp is not a certificate-based digital signature or proof of signer identity.

## Use cases

- Add a visible review mark or seal to selected PDF pages
- Place one seal across adjacent pages in a document run
- Add page numbers or watermarks to selected pages
- Combine scanned images into a multi-page PDF
- Split a PDF or export selected pages as images

## FAQ

### How do I combine several photos into one PDF?

Add the supported photos in the Images to PDF tool, arrange them in reading order, set the page options and export one document.

### Can these tools edit existing PDF text?

No. The tools cover conversion, splitting and visible marks, but they do not rewrite paragraphs or change embedded fonts.
