About Edit PDF

Pixenith's PDF Editor is a browser-based workspace for marking up any PDF. Upload your file, use the toolbar to add text, yellow highlights, rectangles, ovals, freehand ink and stamp images on any page, then download the edited PDF.

The editor includes page thumbnails, zoom controls, undo/redo, and object selection — everything you need for contracts, forms, review markup and quick fixes without desktop software.

Frequently asked questions

Is this a full Acrobat-style editor?
Pixenith's editor covers visual annotation — text, highlights, shapes, freehand draw and image stamps on any page. For watermarks, page numbers, digital signatures, or form filling, use our dedicated tools in the Edit category.
Can I edit existing PDF text?
This editor adds overlays on top of the page. Changing the original embedded text requires converting to Word (PDF to Word) and back, or a desktop PDF suite.
What coordinate system do you use?
Standard PDF: origin at bottom-left, units in points (72 pt = 1 inch). A US Letter page is 612 x 792 points.
Can the overlay be transparent / semi-transparent?
Current endpoint draws solid Helvetica text and full-opacity images. For semi-transparent watermark stamps, use the dedicated Watermark PDF tool.
Is there a limit on number of edits per call?
Practical limit ~500 edits per call. Beyond that, contact us about the batch API for the Business plan.
