Frequently Asked Questions
Are these tools really free?
Yes. Every tool on TinySandy is free to use, with no sign-up and no usage counter.
Are my files uploaded to a server?
Almost every tool runs entirely in your browser, so your files and text never leave your device. A few document conversions (Word, Excel, PowerPoint and PDF to or from Office formats) can optionally use a Python server on this site for better layout. That option is shown only when it is available, it is off by default, and each page tells you exactly what happens. See the Privacy Policy.
Do I need an account?
No. There is no registration or login. The “Recently used” and “Saved” lists are stored only in your own browser.
Why does a tool say its result is basic or approximate?
Some conversions, for example PDF to Word, cannot be done perfectly in a browser. Those pages say clearly what is preserved and what is not, so you can decide whether the result is good enough.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox and Safari. Some tools, such as image tools, rely on the Canvas API and the File API, which all of these support.
How can I request a new tool or report a problem?
Use the contact page or the “Suggest a Tool” box in the footer.
