Add Comments to a PDF on Windows
Windows has no built-in way to leave a proper comment on a PDF. The Edge reader can highlight and scribble, but if you want a tidy, attributed note box on a specific spot, you are usually pushed toward Acrobat or another install, which is a lot for a few remarks. FixTools handles it in the browser. Open the tool in Edge or Chrome, upload the PDF, and the first page loads into a live preview. Type each comment, set the page and an author name, and click exactly where the box should sit. Process the file and a clean annotated PDF downloads to your PC. The comments are rendered into the page on the server, so the file is uploaded over an encrypted connection and deleted automatically once your download is ready. On a work laptop where you cannot install software, this is often the quickest way to mark up a document at all.

Adding comments on a locked-down work PC
Corporate Windows machines often block software installs, so reaching for Acrobat or a desktop annotator simply is not an option. That leaves people copying remarks into an email or printing the document to scribble on it, both of which lose the connection between the note and the place it refers to.
Because FixTools runs as a web page, it works inside the browser that IT already allows. You upload the PDF, place your comments on the exact spots, and download the marked-up file, with no admin rights and nothing installed. The upload is encrypted and the file is deleted after processing, which also keeps it friendly to handling documents on a managed device.
How to use this tool
Open the tool in Edge or Chrome, upload the PDF, type a comment, and click where it belongs on the preview. Process and the annotated file downloads to your PC.

Real-world examples
Common situations where this approach makes a real difference:
No admin rights
An employee on a locked-down laptop cannot install Acrobat but can annotate the PDF in Edge.
Edge reader is not enough
Someone wants tidy, attributed comment boxes rather than the freehand scribbles the built-in reader offers.
Shared office PC
A worker on a shared machine adds notes online rather than installing software others would inherit.
Fast turnaround
A reviewer marks up a report in the browser and returns it before a same-day deadline.
Pro tips
Get better results with these expert suggestions:
Maximize the window
A full-screen browser makes the preview larger, so placing a comment on a small form field is easier.
Drag from File Explorer
Drag the PDF straight from a File Explorer window onto the upload area instead of browsing for it.
Pin the tab
Pin the tool tab in Edge or Chrome so it is ready the next time a document needs comments.
Compress large results
If the annotated PDF is heavy, run it through the PDF Compressor before attaching it to email.
