Frequently asked questions
Is PDFSwift really free?
Yes. Every tool on PDFSwift is free, with no file-size limits, no watermarks, and no account required.
Are my PDFs uploaded to your servers?
No. PDFSwift processes everything in your browser using WebAssembly. Your documents never leave your device.
Does it work offline?
After the first page load, most tools work offline. The only exception is OCR, which downloads a recognition engine on first use (then it's cached for offline use).
Which browsers are supported?
Any modern browser with WebAssembly support — Chrome, Edge, Firefox, Safari, and Brave on both desktop and mobile.
Is there a file-size limit?
There is no hard limit, but very large PDFs may be slow on older devices because all the work happens locally. On modern laptops, PDFs up to a few hundred MB work comfortably.
