How to Compare PDFs

Select Both Files: Drag and drop your original PDF into the left box and the revised PDF into the right box. The comparison will start automatically.
Visual Pixel Comparison: This tool doesn't just check text; it creates a visual snapshot of each page and compares them pixel by pixel. This method finds all changes, including moved images, formatting tweaks, and text edits.
Review the Differences: The results are shown in a side-by-side view with synchronized scrolling. Pages with changes will be highlighted in red. Use the "Show Differences" toggle to see the changes more clearly and the "Prev/Next" buttons to jump between them.
Download & Reset: You can download a `.zip` archive containing images of all pages where differences were found. Click "Start Over" to compare new files.
