Frequently Asked Questions
No. Data Studio runs entirely in your browser using JavaScript. Your data is read into your device's memory, processed there, and saved straight to your downloads. Nothing is sent over the network, so no one else ever receives a copy.
AnyTool Studio sets no upload limit because nothing is uploaded. The practical limit is your device's available memory, so very large files may be slow on phones or older computers. If Data Studio struggles with a big file, try a smaller one.
Yes. Because your data never leaves your device, confidential contracts, financial records and personal files are not exposed to a third-party server. Everything is cleared from memory when you close the tab.
Yes. Data Studio is 100% free, with no signup, no account and no usage caps.
