PDF Editor FAQ

Is my PDF uploaded to any server while editing?

No. All rendering, editing, and flattening happens entirely inside your web browser using WebAssembly and client-side JavaScript. Your confidential files never leave your computer.

Can I edit existing text in the PDF document?

You can add new text boxes, cover content with shapes or whiteout, and highlight or draw over existing text. True reflowable inline text editing is not supported as standard PDFs store text as fixed glyph positions.

How do I add my signature to a document?

Click the 'Signature' tool button, draw your signature on the interactive signature pad, and click 'Add Signature'. You can then move and resize the signature anywhere on your document.

Is there a limit on how many pages I can edit?

There are no arbitrary page limits. Because processing runs in your local browser memory, documents with 50-100 pages work smoothly on modern devices.
