Frequently Asked Questions

Everything you need to know about using PDFToolsHub — supported formats, file sizes, how processing works, privacy and downloads. Each tool page also has its own questions and answers.

General

A free collection of online tools for working with PDF files — converting, merging, splitting, compressing, signing, protecting and more — that you use directly in your web browser.

Yes, it's free, and no — there are no accounts or sign-ups. Open a tool and use it.

Recent versions of Chrome, Edge, Firefox and Safari on Windows, macOS, Linux, Android and iOS. The site adapts to phones, tablets and desktops.

Supported formats

Depending on the tool: JPG (.jpg, .jpeg), PNG (.png), WEBP (.webp) and PDF (.pdf). Each tool page lists exactly which formats it accepts, and files are checked when you add them.

JPG and PNG images. You can also create PDFs from JPG, PNG and WEBP images.

Files are checked by their contents, not just their name. A file is rejected if it's the wrong type for the tool, empty, too large, damaged, or — for most PDF tools — password-protected. The message tells you which.

File size

PDF tools accept files up to 50 MB each, and image tools up to 20 MB per image. The limit is shown on each tool's upload area.

The tools use your device's own processor and memory, so very large files can take longer on older phones and computers. Closing other tabs can help.

Processing

All 22 tools process files entirely in your browser, on your own device. Nothing is sent to our server or to any other service.

No. Everything works in your web browser. Some tools download a processing engine the first time you use them, which is then cached by your browser.

Most tools copy your content exactly. Tools that intentionally change content say so: for example, Compress PDF re-saves photos at a lower resolution, and PDF to JPG saves pages as compressed images.

Privacy

No. Every tool runs in your browser, so your files never leave your device.

No. We never receive your files, so there is nothing for us to store.

No. Passwords you type into Protect PDF or Encrypt PDF are used only in your browser to encrypt the file, and are never sent to us or stored.

No. We don't set cookies or use analytics or advertising. Your light/dark mode choice is saved in your browser's local storage. See the Privacy Policy for details.

Downloading files

It's saved by your browser, usually to your Downloads folder. On iPhone and iPad it's saved to the Files app; on Android, to Downloads.

When a tool creates several files — for example splitting a PDF into parts or converting several pages to images — they're bundled into one ZIP so you can download them together. Most computers and phones open ZIP files directly.

Only while the page is open. Results are kept in your browser, not on our server, so download your file before closing the page or clicking “Start again”.
