Frequently Asked Questions
Does my data leave the browser?
Processing stays in your browser. Nothing is uploaded to ToolWorld servers.
Is MD5 secure?
MD5 is for checksums only — not integrity against attackers.
Large files?
The whole file is read into memory; very large files may strain the browser.
