Frequently asked questions

Are ToolNest tools really free?

Yes — every tool on ToolNest is completely free with no hidden limits, watermarks, or sign-up requirements.

Are my files uploaded to a server?

No. All tools run entirely in your browser using JavaScript. Your images, PDFs and data never leave your device, which makes ToolNest one of the most private tool sites available.

Do the tools work on mobile?

Yes — every tool works on Android and iPhone browsers as well as desktop Chrome, Edge, Firefox and Safari.

Is there a file size limit?

There is no artificial limit. Because processing happens on your own device, very large files are only limited by your device memory.
