How can I compare two PDF files for differences?
You can use our free Compare PDF tool. Simply upload the original and modified PDF files, and the tool will display them side-by-side. You can then scroll through both documents simultaneously to visually spot changes, text differences, or layout shifts.
Is there a way to compare PDF files for free?
Yes, this Compare PDF tool is 100% free. It runs entirely in your browser using JavaScript, meaning you don't need to pay for software like Adobe Acrobat Pro to perform basic visual comparisons.
Is my PDF data safe when using this comparison tool?
Absolutely. Since the tool processes files locally in your browser using PDF.js, your files are never uploaded to any external server. Your data remains private and secure on your device.
