Annotate PDFs and documents without the back-and-forth
Upload a PDF or document, click anywhere to pin a comment, and send one link. Reviewers add feedback right on the page — no account, no Acrobat, no email attachments.
No credit card · Clients need no account
Mark up a PDF or document and collect feedback in one link
A PDF annotation tool lets you comment directly on a document instead of describing changes in a separate email. Markify renders each page of your PDF in the browser and lets you drop numbered pins exactly where the change belongs.
There is nothing to install and no desktop app required. Share the link and reviewers can read and add comments from any browser without signing up — perfect for proposals, contracts, design proofs and reports.
