How to Edit PDF
This editor runs entirely client-side: your PDF is never sent to a server. PDF.js renders each page onto a canvas so you have a visual working surface, and a transparent overlay canvas on top captures your edits — text boxes, rectangles, lines, image stamps, and highlighter marks — as you place them.
Each tool you select (text, rectangle, line, image, or highlight) behaves like a distinct drawing mode: clicking and dragging on the page draws the shape live with adjustable fill color, opacity, border color, and border width, all previewed instantly on the overlay before you save.
When you save, PDF-lib loads the original PDF bytes and draws every one of your added elements directly onto the corresponding page at the correct coordinates, then re-saves the file — the edits become a permanent part of the PDF's page content, not a removable annotation layer.
Safe & Secure
Your files are uploaded over an encrypted (SSL) connection. We don't store, read, or share the contents of your files — they're processed to generate your result and are not retained on our servers afterward.
Who Uses Edit PDF?
- Fixing a typo or updating a date directly in a PDF without going back to the original source file.
- Adding a text box, comment, or annotation to a PDF before sending it back to a colleague.
- Making a small correction to a form or document that only exists as a PDF.
Limitations to Avoid
- Trying to make extensive layout changes directly in a PDF rather than in the original source document (Word, InDesign, etc.) — PDF editing is best for small, targeted changes, not a full redesign.
- Not saving/downloading the edited version before closing the tab — always confirm the edited file downloaded successfully.
Tips for Best Results
- For substantial content changes, it's often faster to convert to Word, edit there, and convert back to PDF rather than editing the PDF directly.
- Match the font and size of surrounding text when adding new text so the edit blends in cleanly.
Privacy Commitment
We respect your privacy. All files are processed securely and are never sold, shared, or used for anything beyond generating your result.
