Use PDF Diff in the browser for quick PDF text comparison workflows. MKDiff keeps the page focused on practical input, preview, and review steps so you can finish a one-off task without installing a desktop utility.
What does PDF Diff compare?
MKDiff extracts readable text from two PDF files and compares the document content locally. It can find wording changes, but it is not a pixel-perfect layout, font, annotation, or scanned-image comparison.
Compare two PDF files by extracted text.
Review document revisions before sharing.
Check PDF exports without installing a desktop diff tool.
