Why use this tool: Compare two PDFs side by side

Open two documents and review their pages side by side with synchronised navigation.

Private browser processing

The tool uses the editor and keeps the document on your device. You do not have to wait for an upload or trust a cloud service with the file contents.

Review before download

Review the result before downloading and continue using text, signature, image and page organization tools. Changes are written only when you choose to export a new PDF.

Original and compatibility

Keep a copy of the original when working with important documents. Complex PDFs can contain embedded fonts, layers or restrictions that depend on the software used to create them.

Long and complex documents

Multi-page documents use progressive thumbnails and an automatic mode for large files. Pages do not have to be rendered all at once, which reduces memory use and interface delays. Actual performance depends on the device, file size and graphical complexity of the PDF.

Check before sharing

Before exporting, review the pages and every element you added. The downloaded file is a new copy, which preserves the original and lets you compare the result. For legal or administrative documents, always confirm the required signature type, document requirements and PDF compatibility expected by the recipient.
