OCR text search

OCR text search

Scans every page (including scanned/image-only pages with no selectable text) so you can search for a word or phrase.

PDF to Word

PDF to Word

Extracts the real text where the PDF has it, and runs OCR automatically on scanned/image-only pages. Works best for simple, single-column documents — complex layouts, tables, and multi-column text won't be preserved exactly.

PDF to PowerPoint

PDF to PowerPoint

Each page becomes one slide, rendered as a full-page image — layout, fonts, and graphics come out exactly as they look in the PDF. Runs entirely in your browser.

How to add a watermark to a PDF online

  1. Choose the PDF you want to watermark.
  2. Type your watermark text and adjust the opacity — the preview updates live on page 1.
  3. Click Apply & download to save the watermarked PDF — instantly, right in your browser tab.

Why watermark PDFs with VitePDF

Frequently asked questions

Is it safe to watermark PDFs on this site?

Yes — your file never leaves your device. VitePDF runs entirely in your browser tab; nothing is sent to a server.

Can I control how visible the watermark is?

Yes — the opacity slider lets you make it subtle or bold, and the live preview shows the result before you download.

Is there a file size or page limit?

No artificial limit — the only constraint is your own device's memory and processing power.
