The complete PDF toolkit

OpenPDF gives you every PDF tool you need in one place. Merge multiple PDF files into a single document, split large PDFs into smaller parts, compress PDFs to reduce file size, convert images to PDF or PDF pages to images, remove unwanted pages, and rotate pages to the correct orientation.

Unlike most online PDF tools, OpenPDF processes everything client-side using WebAssembly and JavaScript. Your files never leave your device — they are never uploaded to any server. This means faster processing, complete privacy, and the ability to work offline.

OpenPDF is completely free with no file size limits, no daily usage caps, and no watermarks. It works on any modern browser including Chrome, Firefox, Safari, and Edge on desktop and mobile devices. No installation or account required.

Frequently asked questions

Is OpenPDF really free?

Absolutely. All processing happens in your browser using JavaScript. Your files are never uploaded to any server. We have no access to your documents.

What file size limits apply?

There are no server-side limits since everything runs locally. Performance depends on your device, but most PDFs under 100 MB process quickly.

Does it work on mobile?

Do I need to create an account?

No. OpenPDF requires no sign-up, no login, and no personal information. Just open a tool and start working.
