How does Compare PDF work?

See which lines were added or removed between two versions. Add your files above, adjust anything you want to change, and press the button. The result downloads straight to your device.

Are my files uploaded anywhere?

No. This tool runs entirely in your browser. Your files are read into memory, processed on your device, and discarded when you close the tab.

Do I need an account?

No. Every tool on FileTools360 works without signing up, and there is no watermark on the output.

What is the file size limit?

200 MB per file. Since everything runs locally, your device's available memory is the real constraint.
