What is Edit PDF?

Edit PDF lets you add text, highlights and freehand drawings directly onto any PDF page. All editing happens in your browser — your file never leaves your device. Annotate contracts, mark up documents, or add notes and then download the finished PDF.

How It Works

Upload a PDF and choose a tool: Text to click and type anywhere on the page, Highlight to drag and mark passages, or Draw for freehand pen annotations. Switch between pages using the thumbnail strip. When you are happy, click Save & Download to get the annotated PDF.

How to Use

  1. 1

    Upload your PDF

    Drop your PDF file onto the upload zone. Pages load as an editable canvas in your browser.

  2. 2

    Select a tool

    Choose from the toolbar: add text, highlight, draw, insert shapes, white-out content, or add images.

  3. 3

    Make your edits

    Click anywhere on the page to add or modify content. Drag elements to reposition them. Use undo to correct mistakes.

  4. 4

    Apply changes

    Edits are applied non-destructively as an overlay layer on top of the original PDF content.

  5. 5

    Download

    Click "Download Edited PDF" to save the modified document to your device.

Why Choose This Tool

Three Annotation Modes

Switch between Text, Highlight, and Freehand Draw modes to cover the full range of common PDF markup needs.

Multi-Page Navigation

A thumbnail strip lets you jump between pages and annotate each one independently within the same session.

Undo Per Annotation

Remove the last annotation step by step with the Undo button, rather than losing all your work and starting over.

Drawings as Embedded Images

Freehand drawings are rasterized to transparent PNG and embedded in the PDF page, ensuring consistent appearance in all readers.

No Content Alteration

Annotations are added as an overlay layer — the original text, images, and layout of the PDF are never modified.

Fully Private

All annotation processing happens locally in your browser — your document is never uploaded to any server.
