PDF tools that never upload your file
Compress, merge, split, sign and convert PDFs in your browser. Docmint processes every file on your own device, so it never reaches a server: ours or anyone else's.
Where your file goes
Most online PDF tools
- 1. Your file is uploaded to the provider's servers.
- 2. It is processed on their servers.
- 3. You download the result; the provider deletes the file later, by its own policy.
Docmint
- 1. Your browser reads the file from your device.
- 2. It is processed on your device, by code running in the page.
- 3. You save the result. No copy ever reached us, so there is nothing to delete.
Check it yourself: open your browser's developer tools, go to the Network tab and run any tool. No request carries your file to a server.
When it matters
Work or school devices
Some organisations block or discourage uploading documents to third-party sites. A tool that keeps the file local avoids the question.
Slow or metered connections
Nothing is uploaded or downloaded from a server, so a 50 MB PDF does not cost 100 MB of data or minutes of waiting.
Files you'd rather keep to yourself
Bank statements, payslips, IDs and tax forms stay on your device while you compress or combine them.
Tools that never upload your file
Every Docmint tool works this way; these are the ones people use most for this. See all Docmint tools.
Questions
How can a PDF tool work without uploading?
Modern browsers can run full PDF libraries (JavaScript and WebAssembly). The page loads that code once, then your file is read and processed on your device, the same way a desktop app would.
Does anything leave my device?
The file never does. Docmint counts how many runs you use each day and, only if you accept analytics, which pages and tools you use. File names and contents are never included. If you use the AI assistant, only the words you type are sent to it, never the file.
How do I check?
Open your browser's developer tools, go to the Network tab and run a tool. You will see the page's own code and the run count, but no request carrying your file.
Is it free?
Yes: 3 free runs a day without an account, 10 with a free account. Pro removes the daily limit.
