Frequently Asked Questions

Are my PDF files uploaded to your server?
No. All PDF processing happens entirely in your browser using WebAssembly and JavaScript. Your files never leave your computer. We don't have servers that receive or store your documents — there is nothing to upload to.
Is PDF Toolbox really free?
Yes, all tools are completely free with no daily limits. We may introduce a Pro tier in the future with advanced features like batch processing and OCR, but the core tools will always remain free.
What's the maximum file size?
We recommend files up to 100 MB for optimal performance. Since processing happens in your browser, larger files depend on your device's memory and processing power.
Can I use PDF Toolbox on mobile?
Yes! PDF Toolbox works on any modern browser — desktop, tablet, or mobile. Chrome, Safari, Firefox, and Edge are all supported.
How do you compare to SmallPDF or iLovePDF?
Unlike those services, PDF Toolbox does not upload your files to a server. This means: (1) your documents are completely private, (2) there are no upload/download wait times, and (3) no daily usage limits.
