Show HN: NoUploadTools – Free Tools that don't upload your files
nouploadtools.com
What is NoUploadTools?
Most online converters and utilities make you upload files to remote servers — meaning your documents, photos, IDs, contracts, or private notes are sent to a third party you don’t control. NoUploadTools takes a different approach:
Everything runs in your browser, so your files never leave your device. nouploadtools.com
No uploads, no server processing, and no cloud storage. nouploadtools.com
Tools can even work offline once loaded. nouploadtools.com
Designed for privacy-aware users — freelancers, legal/professional workflows, students, or anyone wary of uploading sensitive data. nouploadtools.com
