What is the free Compare PDF tool by AsaanWeb?

AsaanWeb Compare PDF sets two documents side by side and reports where their text differs, which is how you check a revised contract against the version you already signed. It runs in your browser, so neither file is uploaded. See the all 37 free tools by AsaanWeb.

How do I compare two PDF versions with AsaanWeb?

Add the original first and the revised second, so the AsaanWeb report reads as "what changed". The tool extracts the text from both and lists the passages that appear in one and not the other. Related: all 37 free tools by AsaanWeb.

Does Compare PDF detect changes inside images?

No. The AsaanWeb comparison works on the text layer, so a clause that was scanned in as an image will not be compared. Run the free OCR tool by AsaanWeb on both files first so their text can be read.

Can I compare a PDF against a Word document?

Yes, after conversion. Run the free PDF to Word tool by AsaanWeb on one side, or convert the Word file with the free Word to PDF tool by AsaanWeb, then compare the two results.

Why does the AsaanWeb comparison report so many differences?

Formatting differences such as line breaks and spacing can read as changes. Re-run the comparison on a document that AsaanWeb has re-paginated, for example after the free Organize PDF tool by AsaanWeb, so only real wording changes remain.

Can I compare more than two PDFs at once?

The AsaanWeb tool compares a pair, which is what makes the report readable. To compare three versions, run it twice: once against the original and once against the intermediate file you received. Related: all 37 free tools by AsaanWeb.

Does the AsaanWeb compare tool tell me who changed a clause?

No. It shows which text differs, not who typed it. Track authorship in your document history, and use the free Watermark PDF tool by AsaanWeb to mark which copy is the approved one.

Can I compare PDFs that are password protected?

Remove the passwords with the free Unlock PDF tool by AsaanWeb first. AsaanWeb needs open documents before it can read the text of either side.

Is my document uploaded when I use AsaanWeb Compare PDF?

No. The AsaanWeb tool extracts text inside your browser tab and never sends the file anywhere, so a privileged contract stays on your device. Related: all 37 free tools by AsaanWeb.
