PDF24 Compare PDF
PDF24 Compare PDF compares two versions of a PDF and marks text that has changed, been added, or been removed. Readers can view the documents side by side, as an overlay, or with a slider. The comparison runs directly in a browser without installation, and PDF24 says the files are not uploaded to its servers. Google Drive is listed as a file-selection option. Use is free, with no registration or time restrictions. PDF24 says transfers are SSL secured and server files are automatically deleted after one hour. For offline processing, PDF24 Creator keeps files on the local PC, but it can only be installed on Windows; Linux and Mac are not supported. PDF24 Tools can be installed from a browser on Android or iPhone and iPad, though it is not distributed through Google Play or the App Store. PDF24 says its online tools are available to companies free of charge and without restriction, and a data-processing agreement can be requested.
