Frequently asked questions
How do I annotate a PDF?
Add your PDF, type your note, choose a colour and position, optionally add a highlight behind it, and apply it to the first page or every page. Download the annotated PDF when you're done.
Can I highlight text in a PDF?
You can place a coloured highlight box with your note at a chosen position. For redacting or hiding content instead, use the Redact PDF tool.
Will the annotation be permanent?
The note is drawn into the PDF, so it stays with the file wherever it's opened — it isn't a removable comment layer.
Is my PDF uploaded?
No. Annotation happens entirely in your browser, so your file never leaves your device.
