Comparing Two PDFs Side by Side
Add both files
Drop the original into the first box and the new version into the second, or click either box to browse. Both are read in your browser, so nothing is uploaded.
Run the comparison
Press Compare. Each page is rendered from both files and lined up, and a difference view marks the changed areas so they stand out at a glance.
Step through the pages
Use the summary to see how many pages changed, then move page by page. File A, File B, and the differences sit next to each other so you can confirm every change.
What the Difference View Shows
The comparison is visual: it lines up the two files page by page and highlights where the pixels differ. That catches any change you can see, not just edited words.
| Change | How it shows up |
|---|---|
| Edited or added text | The changed area is tinted red in the difference view |
| Moved images or blocks | Both the old and new positions are marked as different |
| A page added or removed | Flagged as present in only one file, with the page counts shown |
| Pages that match | Left plain, so your eye goes straight to what changed |
| Formatting or colour shifts | Picked up too, since the check is visual rather than text-only |
When a Visual Compare Is the Right Tool
Confirming nothing changed
A file came back marked as unchanged. Line it up against your copy to be certain, instead of trusting the label.
Spotting a moved figure
Contracts, quotes, and statements can hide a single edited number. The red highlight lands right on it.
Reviewing a design or form
Layout, stamps, and images are all checked, so a shifted logo or a nudged field is caught, not just text.
When to use text compare instead
If you need each inserted and deleted word named as a list, a text-level compare fits better than a visual one.
