How to Annotate a PDF Free Online (No Account, No Acrobat)
Add comments, text boxes, and notes to a PDF online for free — no account, no Adobe subscription. Works on any device and browser.
Adobe Acrobat's online annotation requires a paid account after the free tier runs out. FixMyPDF's annotation tool is completely free with no account — add comments and text notes to any PDF in your browser, on any device.
How to Add Comments to a PDF Online
Go to fixmypdf.in/tools/add-comments. Upload your PDF. Click or tap anywhere on a page to add a comment box. Type your note. Repeat for other locations. Click "Download PDF" when done. No account required.
Types of Annotations Available
Our tool supports text comment boxes (positioned anywhere on the page), which are the most universally compatible annotation type. Comments appear in the PDF's standard annotation layer, visible in Adobe Acrobat, Preview on Mac, Chrome's PDF viewer, and all modern PDF readers.
No Account — No Usage Limits
You can annotate as many PDFs as you need without creating an account. There's no "5 free annotations" limit or daily cap. The processing happens in your browser, so there's no server load for us to limit.
Who Can See Annotations
PDF annotations (comments) are visible to anyone who opens the annotated file in a PDF reader that supports them — which includes all major readers. If you want to send a version without annotations (e.g., the clean final version), use our remove annotations tool to strip them before sharing.
Privacy for Annotated Documents
Your PDF content and your annotation text are processed entirely in your browser. A document you're annotating for legal review, a marked-up contract, or commented academic paper never reaches FixMyPDF's servers.
Works Across All Devices
The annotation tool is accessible from any device with a modern browser. On mobile (iPhone, Android), tap to place comments and use the on-screen keyboard to type. On desktop (Mac, Windows), use mouse clicks to position comments precisely.
After Annotating
Annotated PDFs can be flattened to make comments permanent (useful before printing), compressed if the file grew large, or password-protected before sharing for review.
