Compare the text of two PDF files and get a line-by-line report of the differences.
Two versions, one comma moved. I will find that comma.— Poulpi
First file (A)
Second file (B)
The comparison is based on the actual text of the documents. Scanned PDFs must first go through OCR.
The ability to compare two PDFs lets you spot at a glance what changed between two versions of the same document, without rereading every line by hand. That matters when a contract comes back signed or annotated: instead of guessing what moved, you see exactly which clauses were edited. To compare PDF versions this way removes nasty surprises and makes every review safer.
The situations are varied: proofread a revised report to check a colleague's corrections, verify an amended quote before signing, review an updated policy, or confirm that a returned document still matches the original. In each case, surfacing the differences turns a slow manual read into a quick, reliable check.
The tool runs a line-by-line text comparison between the two files. Each line is marked as identical, removed or added, giving you a clear PDF diff with no jargon. You follow the logic of the changes much like a track-changes view, right inside your browser.
One honest limit: the comparison relies on real text. If one of your PDFs is a scanned document (an image), run it through the ocr tool first to extract its text, otherwise no difference can be detected. To go further, the pdf-to-word tool turns a PDF into an editable document, and merge combines several files into one. On privacy, everything works with no sign-up and your files are deleted automatically after processing: they are never stored or reused.

Upload the first PDF then the second, and click "Compare". You get a text report marking each line as identical (=), removed (-) or added (+).
The comparison is based on the actual text of the documents. It therefore works on digital PDFs; scanned PDFs (images) must first go through text recognition (OCR).
The tool compares the text of both documents line by line and highlights the differences. It focuses on the textual content rather than on layout or images.
Not directly, because a scan is an image with no usable text layer. Run the documents through character recognition (OCR) first to obtain comparable text.
