Edit PDF Online Free — PrivaTools

TL;DR: Upload a PDF and click anywhere on the page to add text, highlights, white-out boxes, or rectangles — then download the edited version.

Edit PDF online for free — modify text, images, and content directly inside your PDF. Add new text blocks, replace images, and make changes without converting to Word first. Full-featured PDF editor with no watermarks.

Like the rest of the 179-tool PrivaTools suite, Edit PDF is MIT-licensed and self-hostable. The public demo deletes your file as soon as the response leaves the server — verifiable in the open-source codebase on GitHub.

How to Edit PDF with PrivaTools

  1. Drop your PDF — Upload a PDF up to 500 MB. The editor renders each page in a scrolling canvas ready for annotation. No account required.
  2. Choose an annotation tool — Pick text box, highlighter, freehand pen, rectangle, circle, line, or arrow from the toolbar. Set color, opacity, and font size before drawing.
  3. Add your annotations — Click on the page to drop text, drag to draw shapes, or hold-and-drag for freehand strokes. Move, resize, or delete any annotation before saving.
  4. Download the edited PDF — Click Save. Annotations are flattened into the document so they appear identically in Adobe Reader, Preview, Chrome, and every mobile reader.

Frequently Asked Questions

Can I edit the existing text in a PDF?

The editor supports adding new text, shapes, highlights, and freehand drawings on top of the page. Direct editing of existing text glyphs requires re-authoring the document because PDF stores text as positioned glyphs, not as flowing paragraphs.

Are my annotations permanent?

Yes. When you save, annotations are flattened into the PDF so they appear identically in every viewer (Adobe Reader, Preview, Chrome, mobile readers) and cannot be removed by toggling annotation visibility.

What annotation types are available?

Text boxes, freehand pen, highlighter, rectangles, circles, lines, and arrows. You can set color, opacity, line thickness, and font size for each. Move and resize freely before saving.

Is it safe to edit a confidential PDF here?

Yes. The PDF is held in temp memory inside an isolated Docker container only for the duration of your edit session — both input and output are unlinked the moment your download begins. No copy is kept on disk, in logs, or in backups. The editor code is open source under MIT for verification.

What's the file size limit?

500 MB per file with no daily or monthly quota. There is no page-count cap; very long PDFs render page-by-page as you scroll.

Do I need an account or sign-up?

No. No account, no email, no sign-up. The editor loads directly in your browser; the privacy guarantees come from the architecture, not from a user profile.

How is this different from Adobe Acrobat or PDFescape?

Free with no daily limit (PDFescape caps free use at 10 MB / 100 pages, Adobe requires a paid subscription for full editing), no account required, and the entire editor is open source so you can self-host it. We don't store your file or send it to any third-party API.
