QBMFX Highlight, draw and annotate PDF
Mark a document with visible highlights, rectangles or drawing strokes before sharing it with a colleague or customer. Choose the target pages and annotation style, then inspect the color, opacity and placement. These marks help explain a review or print correction while preserving the source document as a separate original. Book centers, freelancers and developers can use this free local workspace without a login or paid conversion API. Keep the original and inspect the downloaded result.
Choose your files and review the settings.
Keep originals and inspect the result before printing. File changes clear previous downloads. Heavy image and OCR work can take longer on a phone.
Using Highlight, draw and annotate PDF
- Choose a PDF and select the pages to mark.

Behind the result
The tool draws additional page artwork using normalized positions and the selected color, opacity and stroke width.
Free tools for everyday work
Book centers, photocopy shops, freelancers and developers can use this workspace without a paid plan or account. Files are processed locally. Prepare website resources from offline setup before disconnecting; Urdu/OCR also needs the separate pack above.

Answers and practical details
Highlight and redaction
A highlight or opaque rectangle can leave the original text extractable. Choose the separate redaction workflow when content must be removed.
Price and accounts
This website workflow is free without a login, subscription or paid conversion tier. Your browser supplies the processing memory and CPU.
Local file handling
Selected documents and generated results are processed on your device. QBMFX does not upload them to a conversion server or save them in a customer database. Hosting, advertising and opening external links are separate network activity.
Offline preparation
Prepare the supported website resources while connected, wait for the ready status and test the workflow before disconnecting. OCR, advanced PDF processing or fonts can need an additional local resource pack. Browser cleanup can remove saved resources.
Installed app availability
The Microsoft Store app and Edge package currently contain the original four tools. Website additions require a separate installed-package release and do not update those packages automatically.
