PDF editing guides
Practical help for adding content to a PDF and checking the finished document.
PDF Canvas is an online PDF editor with tools for adding text, images, visual signatures, drawings and highlights. Choose a guide below, or open the editor to start working on a document.
Add text to a PDF
Place a new text annotation on a page, adjust it and inspect the exported result. Understand the difference between adding text and rewriting existing PDF content.
Add a visual signature
Create a signature-style image from your name and position it on the page. Understand the limits of a visual signature.
Highlight and draw on a PDF
Use pen and highlighter tools to mark a document while keeping the underlying information readable.
Help and export checks
Check a downloaded PDF, investigate common problems and avoid losing your original document.
A useful first test
Start with a non-confidential sample PDF. Make one small change, download the edited document and reopen it in another PDF reader. Confirm the workflow before using it for a document that matters.
What these guides cover
These guides focus on adding content to PDF pages. They do not promise OCR, conversion to Word, rewriting of existing text, secure redaction or certificate-based digital signing. Use only features available in the current editor.
