Batch File MD5 Calculation FAQ

Does this tool support folders?

Reading folders is not yet supported. Please use a related tool that supports directory reading.

Which browsers are supported?

We recommend the latest versions of Chrome, Edge, and Firefox.

Is the data secure? Is it uploaded to a server?

Files are not uploaded. All processing is done locally in your browser, ensuring your data stays private and secure.

Can it calculate other hashes such as SHA256?

Currently only MD5 is supported. If you need more hash algorithms, keep an eye on future updates.

Will large files cause lag?

Large files take slightly longer to calculate. We recommend processing large files in batches for a smoother experience.
