Frequently asked questions
Are these document tools free to use?
Yes. Every document tool on AT USE is free with no account required. You can process your files directly in the browser without signing up or installing software.
What file types do the document tools support?
The upcoming document tools focus on PDF — the most common document format for merging, splitting, compressing, and converting. Support for Word, ODT, and other formats is planned in future tools.
Are my documents uploaded to a server?
Where technically possible, files are processed locally in your browser so they never leave your device. When server processing is required, uploaded files are deleted automatically after your session.
Is there a file size limit for document tools?
Each tool documents its own size limit. As a general guide, standard office PDFs under 20 MB are handled without issue. Very large print-ready or engineering files may have lower caps.
