Frequently asked questions

Is File Checksum (MD5, SHA-256) free?

Yes. There's no sign-up, no watermark and no usage limit.

Are my files uploaded to a server?

No. File Checksum (MD5, SHA-256) runs entirely in your browser. Your files never leave your device and nothing is stored — close the tab and everything is gone.

Is there a file size limit?

Each file can be up to 200.0 MB, and you can process up to 20 files at once. Because processing uses your device's memory, very large files work best on a computer.

Does it work on my phone?

Yes. It works in modern mobile browsers on Android and iPhone. Heavier jobs (large PDFs, OCR) are faster on a computer.
