Frequently Asked Questions
Clear, direct answers regarding privacy, performance, and features.
Using streaming FileReader chunks and WebCrypto native browser methods, files are digested at gigabytes per minute without memory bloat.
Yes. Paste the author-provided SHA-256 or MD5 hash into the verification field to confirm file integrity instantly.
Never. The file data is read through browser memory buffers and digested locally on your CPU.
