Mark up contracts, study material and reports with highlights, underlines, strike-outs, freehand drawing, arrows, boxes and sticky notes. Stamps such as APPROVED or DRAFT can be added in one click.
Comments are saved as standard PDF annotations, so colleagues see them in whatever PDF reader they use, and they can reply or remove them.
How to annotate PDF
- Open your PDF.
- Pick a tool on the Comment tab: highlight, underline, note, pen, shape or stamp.
- Mark up the pages and save the annotated PDF.
Private by design
Most online PDF sites upload your file to their server. AK Smarts PDF opens and processes it inside your own browser, on your computer or phone, so salary slips, bank statements, Aadhaar and PAN copies, and contracts never leave your device. It works on Windows, Mac, Android and iPhone, and you can install it like an app to open PDFs with a double-click.
Questions
Will others see my comments?
Yes. Annotations are saved in the standard PDF format, so they show in other PDF readers too.
Can I flatten comments so nobody can remove them?
Yes. Use Flatten PDF after annotating to make the comments part of the page.
Does annotating change the original text?
No. Comments sit on top of the page; the original content stays as it was.
Is AK Smarts PDF safe for confidential files?
Yes. Files are opened and processed on your own computer or phone and are never uploaded to our server. Only e-Sign sends a short fingerprint of the document, never the document itself.
Does Annotate PDF work on my phone?
Yes. AK Smarts PDF works in Chrome, Safari, Edge and Firefox on Android, iPhone, Windows and Mac. You can also install it like an app.
