Frequently asked questions
Is PDFToolz really free?
Yes. Every tool is free, with no daily quotas, watermarks or account required. Processing happens on your device; practical file-size limits depend on your browser and available memory.
Are my PDF files uploaded to a server?
No. All processing runs locally in your browser using WebAssembly and JavaScript. Your documents never leave your device, which also means there is nothing for us to store, scan or leak.
Do I need to install any software?
No installation is needed. PDFToolz works in any modern browser — Chrome, Firefox, Safari or Edge — on Windows, macOS, Linux, iOS and Android.
Can I merge, split and compress PDFs offline?
Once a tool page has loaded, the actual processing happens on your device, so a dropped connection mid-task is not a problem. Loading a page for the first time still requires an internet connection.
Is it safe to unlock or password-protect a PDF here?
Yes. Passwords you type and the files you protect or unlock are handled entirely in your browser using AES encryption via qpdf compiled to WebAssembly. Neither the file nor the password is ever transmitted.
What is the maximum file size?
PDFToolz does not impose a server upload limit because files stay on your device. The practical limit depends on your browser, available memory and the complexity of the PDF.
