Cómo usar: Compare PDF
- Drop the original PDF on the left and the changed one on the right.
- Choose word by word (best for contracts) or line by line.
- Read the highlighted differences: added and
removed. - Tick Show only changes to skip the unchanged text.
Spot every edit in a new version
Comparing documents by eye misses small but important changes — a “not” added to a clause, a different date, a number moved. This tool extracts the text of both PDFs and runs a word-level diff, the same method code review tools use, so every insertion and deletion is highlighted. It compares the text; layout, images and formatting changes aren’t shown.
Private by design
Most online PDF services upload your document to their servers. This tool processes the file entirely in your browser with open-source libraries (pdf-lib and PDF.js), so contracts, invoices, bank statements and IDs never leave your device. It works offline once the page has loaded, and there are no file-count limits, watermarks or sign-ups.
Comparing plain text or code instead? Use the Diff Checker. Need the text itself? PDF to Text extracts it.
