Alternative

What is a free alternative to PDF24 that does not upload my files?

Short answer

For everyday jobs like merging, splitting and compressing PDFs, browser-based tools that process the file on your own device are a free alternative to PDF24's online tools. PDF24 is genuinely free too, but its online tools state that files are processed in the cloud on its servers and deleted afterwards, while a client-side tool never uploads the document at all.

The honest comparison

PDF24 deserves credit: its online tools are free to use. The structural difference is where the work happens. PDF24's own pages say files are processed in the cloud on its servers and are deleted after a short period. That is a reasonable policy, but it still means your document travels to and briefly exists on someone else's infrastructure. Fully client-side tools do the merge, split or compression inside your browser, so there is no upload, no server copy and nothing to delete.

When each approach fits

If the document is public or trivial, a server-side tool is fine. If it is a contract, a bank statement, an ID scan or anything covered by a confidentiality clause, the no-upload route is the safer default because the file simply never leaves your machine. The browser tools here need no installation and no account, and cover merging, splitting and compressing directly.
