Frequently asked questions

What is CalcDepo FileUtils?

A set of 518 small file tools for everyday jobs: resize and convert images, merge and split PDFs, create and extract ZIP archives, hash files, and clean up text. Each tool runs in your browser.

Are my files uploaded anywhere?

No. Files are processed on your device and are never sent to our servers. The one exception is that PDF and ZIP tools load their helper libraries from a content delivery network the first time they run. See the disclaimer for details.

How do I find a tool?

Move through the slides with the arrows, the dots, or the arrow keys. Each slide is one category. You can also type in the search box at the top, for example “pdf” or “resize”, or use the Categories menu. For the full list, open All tools.

How do I run a tool?

Click a tool, then drop your files into the box or click it to choose them. Change any settings you need, press Run tool, and download each result. If a tool produces several files, you can download them all as one ZIP.

What is the file size limit?

Each file can be up to 10 MB. Larger files are skipped, and the message tells you which ones.

Does it work on my keyboard and screen reader?

Yes. Use the Left and Right arrows, Page Up and Page Down, Home, and End to move between slides. Press Escape to close a tool window. Buttons and tool cards can be reached with Tab.

Is the output guaranteed to be correct?

No guarantee is given. Keep a copy of your original file and check important output before you rely on it. The disclaimer explains this in full.
