Compare Two PDF Documents Side by Side
Upload the original and the revised PDF. The tool renders both documents and highlights every visual difference between them. See exactly what changed - added text, deleted paragraphs, moved images, formatting changes. Color-coded overlays make differences impossible to miss.
Spot Changes Between Document Versions
Reviewing a revised contract, updated report, or new version of a design? Compare both versions instantly instead of reading page by page. The tool catches changes in text, images, tables, headers, footers, and layout. Step through each difference one by one or review them all at once.
Compare PDF Files Without Uploading
Both documents stay on your device. The entire comparison runs in your browser - no server processing, no temporary copies stored remotely. Compare confidential contracts, legal revisions, financial reports, and sensitive documents with complete privacy.
Visual Comparison Catches Everything
The comparison is visual - it catches any change that affects how the page looks. Text edits, font changes, image swaps, spacing adjustments, moved elements. Even subtle changes like a single comma or a slightly repositioned logo are highlighted. Nothing slips through.
