Question 4

Are my files safe?

Accepted Answer

Absolutely. All files are processed 100% in your browser using client-side JavaScript. Your files are never uploaded to our servers or any third-party service. Once you close the tab, all data is gone.

Question 5

Does ToolMasterApp collect my data?

Accepted Answer

We do not collect, store, or sell any user data. We use minimal analytics (page views) to improve the experience, but we never track what files you process or what tools you use.

Question 6

Is it safe to process sensitive documents?

Accepted Answer

Yes. Since all processing happens locally in your browser, it is safe to process confidential contracts, personal information, medical records, or any sensitive content.

Question 7

What types of tools are available?

Accepted Answer

ToolMasterApp offers 60+ tools across categories: Image Tools (compress, resize, convert, watermark), PDF Tools (merge, split, compress, protect), Text Tools (formatter, diff, word counter), Developer Tools (JSON formatter, regex tester, JWT decoder, API tester), and more.

Question 8

What file formats are supported?

Accepted Answer

We support all major formats including JPEG, PNG, WebP, AVIF, SVG, GIF for images; PDF, DOCX for documents; JSON, CSV, XML for data; and many more depending on the tool.

Question 9

Is there a file size limit?

Accepted Answer

Since processing happens in your browser, limits depend on your device's memory. Most tools handle files up to 50-100MB without issues. For very large files, we recommend processing in batches.

Question 10

Can I use tools on my phone?

Accepted Answer

Yes! All tools are fully responsive and optimized for mobile and tablet devices. The interface adapts to your screen size for the best experience.

Question 11

What browsers are supported?

ToolMasterApp works on all modern browsers: Chrome, Firefox, Safari, Edge, Brave, and Opera. We recommend using the latest version for the best performance.

Question 12

Do I need an internet connection?

Accepted Answer

An internet connection is needed to load the website initially. However, since processing happens locally, most tools continue to work even if your connection drops mid-use.

Question 13

Why is client-side processing better?

Accepted Answer

Client-side processing means your files never leave your device, ensuring 100% privacy. It's also faster since there's no upload/download time, and it works offline after the page loads.
