How It Works
1. Upload PDF
Select any PDF file. It loads instantly in your browser.
2. Annotate
Use highlight or underline tools. Choose colors and draw on the document.
3. Save
Download your annotated PDF. Annotations are embedded permanently.
Need this in a production workflow?
Move from one-off browser work to larger files, background jobs, API automation, and PDF audio when the document flow grows.
Built for larger private PDFs
Most cloud PDF tools need uploads, accounts, or free-tier caps for large files. ExactPDF processes files locally in your browser, supports PDFs up to 150 MB on this tool surface, and never adds a watermark or daily quota.
