Compare PDF

Upload two versions of a document and instantly see which lines were added, removed, or changed between them.

Everything happens in your browser — neither PDF is uploaded anywhere. This compares extracted text line-by-line, so purely visual/formatting-only changes may not be detected.

About comparing PDFs

How does this detect differences?

Text is extracted from both PDFs and compared line by line — lines only in PDF A are shown as removed, lines only in PDF B are shown as added.

Will this catch layout or formatting changes?

Only text content differences are detected — purely visual changes like font, color, or spacing shifts with identical text won't show up as a difference.

Are my files uploaded anywhere?

No — comparison happens entirely in your browser. Neither PDF ever leaves your device.
