Edit PDF
Add text, images, shapes or freehand annotations to a PDF document.
What is Edit PDF Document?
Add text, shapes, highlights, drawings, and images on top of a PDF. Each page is composited into a new PDF. Free, no watermarks, and fully in-browser.
When should you use it?
This tool is useful when you need to add, change, or clean up visible content inside a PDF while staying in your browser.
How Edit PDF Document handles your file
Pages are rendered to a canvas in your browser, your annotations are drawn on top, and the composite is written into a new PDF. Nothing is uploaded.
Your device's own CPU does the work, so there is no upload wait and no server-side copy of your document to retain.
Good to know before you convert
- Annotations are composited onto a rendered image of each page, so the output PDF is image-based. Its text is not selectable or searchable.
- You cannot reflow, re-word, or delete existing text — editing is additive, layered on top of the page.
- Because pages are rasterised, output file size grows with the number of pages edited.
How to use Edit PDF Document
Drag your PDF document into the editor.
Use the toolbar to add text, shapes, freehand drawings, highlights, or images.
Click 'Apply Changes' to composite the annotations and download the edited PDF.

Frequently Asked Questions
Is the editor really free with no watermarks?
Yes. PdfPix adds no branding, watermarks, or stamps to your output.
Can I type text directly on the PDF?
Yes. Choose the text tool, click where the text should appear, and start typing. The text is drawn onto the page as an overlay.
Will the edited PDF still have selectable text?
No, and this matters for some workflows. PdfPix composites your annotations onto a rendered image of each page, so the exported PDF is image-based and its text can no longer be selected, searched, or copied. If you need to keep a live text layer, annotate in a tool that preserves the original content stream.
Are my files uploaded when editing?
No. The editor runs entirely in your browser and your document never leaves your device.
