About MassPDF
MassPDF is a browser-based PDF editor for everyday document changes. It is built for people who need to add text, highlight details, place shapes or images, save drafts, and download an edited PDF without installing desktop software.
What the editor is for
The editor is designed for practical visual changes: completing simple forms, marking study material, adding review notes, labeling documents, and preparing a clean copy for personal, school, or work use.
Free access
MassPDF is currently free to use. Signed-in users can edit documents, save drafts, and download edited PDFs directly.
Privacy-minded workflow
PDF files can contain sensitive information, so MassPDF keeps privacy and account state visible in the product. Users should only upload documents they have the right to process and can read the privacy policy before saving drafts or using account features.
