Common questions

Frequently Asked Questions

Q
Are my files uploaded to 365tools servers?
A
No. Every tool processes your files entirely within your web browser using JavaScript. Your files never leave your device and are never transmitted to any server.
Q
Is 365tools.net really free?
A
Yes, completely free. No subscription, no credits, no usage caps, and no account required. All tools are free to use without any restrictions.
Q
What browsers are supported?
A
All modern browsers — Chrome, Firefox, Safari, Edge, and their mobile equivalents. We recommend keeping your browser up to date for the best experience and widest format support.
Q
Is there a file size limit?
A
There is no server-imposed limit. The practical limit depends on your device's available memory. Most modern computers can comfortably handle files up to several hundred megabytes.
Q
Can I use 365tools for medical or sensitive files?
A
Yes. Our DICOM converter processes files entirely in your browser and strips patient metadata (PHI) before exporting. No medical data ever reaches our servers.
Q
How is 365tools different from Smallpdf, ILovePDF, or Convertio?

Those services upload your files to their servers. 365tools processes everything locally in your browser — no uploads, no fees, and no rate limits.
