Frequently Asked Questions
Does this upload my files?
No. All processing happens locally in your browser for full privacy. Your PDFs never leave your device.
What differences can it detect?
The tool can detect text, layout, image, and metadata-level changes. It highlights visual differences between pages and compares document properties.
Can it compare scanned image PDFs?
Yes, but text comparison requires OCR (coming soon). Visual comparison works for image-based PDFs.
What's the file limit?
Up to 50MB per file, with a combined limit of 500 pages. Larger files may take longer to process.
Is it reliable for design files?
It highlights visual changes, ignoring small rendering shifts. For precise pixel-level comparison, consider using specialized design tools.
Can I compare encrypted PDFs?
No, encrypted or password-protected PDFs are not supported. Please unlock your PDFs before comparing.
How accurate is the comparison?
The tool provides high accuracy for text and metadata comparison. Visual comparison highlights significant changes but may miss subtle differences.
What browsers are supported?
Modern browsers with JavaScript enabled (Chrome, Firefox, Safari, Edge). The tool uses client-side processing, so it works offline after initial load.
