The tool runs on your device, so the largest file it can handle depends on your device's and browser's memory. Very large files can take longer on phones.
Frequently asked questions
Are the files uploaded?
No. Comparison runs in your browser on your own device, and neither file is sent to any server.
What's the difference between text and visual comparison?
Text comparison reads the words in both files and shows what was added or removed. Visual comparison overlays the pages and shows any difference in appearance, even when the text didn't change.
My files are scans. Will comparison work?
Visual comparison works because it compares appearance. Text comparison needs real text, so run both files through OCR PDF first.
Does it work with Arabic text?
Yes. We read Arabic in its correct order before comparing. If one file uses a font without proper character information, false differences may appear, and visual comparison is more reliable.
Can I compare files with a different number of pages?
Yes. Text comparison handles added or removed passages even when page counts change; visual comparison matches each page with its counterpart.
Is it free?
Yes. You can compare files for free without creating an account.
