Cara kerja

Tools like Draftable and Adobe charge for good PDF comparison, and PDF24 uploads your files. This compares two PDFs visually in your browser — neither file leaves your device.

1
You drop in two PDFs
An "original" (A) and a "changed" (B). Both are rendered locally with pdf.js.
2
Each page is rendered to an image
The matching page from each document is drawn to a canvas at the same scale, in your browser.
3
You choose how to compare
Side by side, an onion-skin overlay with an opacity slider, or a pixel-difference view that highlights changed areas in red and reports the percentage changed.
4
You page through the documents
Step through every page; pages that exist in only one file are flagged.

Contracts and drafts are sensitive, and most comparison tools upload them. Here everything is rendered and compared on your device — ideal for reviewing revised agreements, statements, and documents privately.
