Why people trust it

Your files never leave your device

Most online PDF sites upload your files to their servers. Here, everything happens inside your browser, so contracts, IDs and other sensitive documents stay private.

Fast and unlimited

No waiting for uploads or downloads, so even large files are quick. There are no limits on file count or daily usage.

Original quality

Merging, splitting, rotating and organizing copy the original page data instead of re-rendering it, so text and images keep their quality.

Works everywhere

Windows, macOS, Android or iPhone — all you need is a modern browser. Nothing to install.

Frequently asked questions

Is it really free?

Yes. Every feature is free, with no watermarks and no usage limits. The site is supported by the ads shown on the page.

Are my files stored on a server?

No. Your PDF files are never sent to a server. All processing happens in your browser, and the data disappears from memory when you close the page.

Does it work on phones?

Yes. It works in modern mobile browsers such as Chrome, Safari and Samsung Internet. For very large files (hundreds of MB), a computer with more memory is recommended.

Does it work on a slow connection?

Yes. Because nothing is uploaded, speed depends on your device, not your connection. The tools download a small program (about 1-2 MB) the first time you use them.
