Never. PDF Tool Mate processes everything directly in your browser. Your files never leave your device. We have no servers that receive or store your documents. Once you close the tab, every trace is gone.

All tools are built with JavaScript that runs locally in your browser. When you select a file, it is read by your browser and processed on your own computer. No data is sent over the internet. You can even disconnect your wifi and the tools still work!

We use cookies to support Google AdSense, which helps us keep the tools free. Here's the breakdown:

• Essential cookies: Required for basic site functionality.
• Google AdSense cookies: Used to personalize ads, measure their performance, and prevent fraud. These are non-essential and you can opt out via your Google Ad Settings.
• No tracking cookies: We do not use analytics cookies, tracking pixels, or fingerprinting tools. We do not sell or share your data.

By using our site, you consent to the use of cookies for ad personalization as described in our Privacy Policy.

Absolutely. Because your files never leave your computer, there is zero risk of interception, data leaks, or unauthorized access. We recommend PDF Tool Mate specifically for sensitive documents that should never be uploaded to a server.

Currently we provide four powerful tools:

• Merge PDF – combine multiple PDFs
• Split PDF – extract pages or split into files
• Delete PDF pages – remove unwanted pages
• Images to PDF – convert JPG, PNG, WEBP to PDF

More tools (compress, PDF to images, watermark) are coming soon. All will follow the same zero-upload principle.

No artificial limits—the only constraint is your device's memory (RAM). For very large files (thousands of pages), performance may depend on your computer. But we don't cap file size or charge for bigger files.

No. Everything works in your browser (Chrome, Firefox, Edge, Safari). No downloads, no plugins, no signups. Just open the site and use the tools.

Yes! The site is fully responsive and works on smartphones and tablets. The tools run in your mobile browser with the same privacy guarantees.

Yes, forever free. We don't charge, and we don't have "premium" plans. We believe basic PDF utilities should be accessible to everyone without hidden costs or subscriptions. We support the site through privacy-respecting ads (Google AdSense) and donations.

We use Google AdSense to display non-intrusive ads. This allows us to keep the tools free. AdSense uses cookies to personalize ads and measure performance. We also accept donations. We never sell user data or upload documents. Our business model aligns with our privacy promise.

We have a transparent, human-readable Privacy Policy. In short: we never see your files. We use cookies for AdSense (with your consent). You can manage your ad preferences via Google Ad Settings.

Yes. We comply with GDPR and CCPA by being transparent about the cookies used for AdSense. While we don't use a popup banner (for now), we provide clear information here and in our Privacy Policy, and we respect "Do Not Track" signals. You can opt out of personalized ads via Google Ad Settings.

First, try a smaller file to see if it's a memory issue. Refresh the page and try again. If problems persist, switch to a modern browser (Chrome, Edge, or Firefox) and ensure JavaScript is enabled. Because everything runs locally, performance depends on your device.

Our tools preserve the original PDF structure and quality. However, some PDFs contain complex forms or fonts that may render differently in browsers. Try downloading the result and opening it in a PDF reader (like Adobe Acrobat) to see the final version.

Currently, our tools do not support encrypted or password-protected PDFs. You'll need to remove the password first (using a tool that you trust). Because we never see your password, we cannot unlock files for you.
