About Our Utility Tools

ZIPs, metadata, and the odd jobs nothing else covers

The Drawer of Useful Odd Jobs

This category collects the tasks that do not fit anywhere else but come up constantly. Someone sends a RAR or 7z archive and nothing on your machine opens it: the ZIP File Converter repacks it as a normal ZIP. A batch of files needs to travel securely: the Password Protected ZIP builds an encrypted archive. A photo might have GPS coordinates buried in it: the Metadata Viewer shows you before you post. A script needs the real channel ID behind a YouTube handle, or an old phone number spelled as a word needs decoding: there are tools for both.

Two Kinds of Tools, Stated Plainly

Most of this category processes files, and those tools run entirely in your browser: archives are built, converted, and encrypted on your device with JavaScript and WebAssembly, and metadata is read from local bytes. The YouTube Channel ID Finder is the exception because a lookup has to ask YouTube a question; the text you type is forwarded to the official API and nothing more. Each tool's page spells out which model it uses, because a privacy claim is only worth something when it is specific.

Frequently Asked Questions

Are the ZIP tools really encrypting in my browser? Yes. The Password Protected ZIP tool builds the archive and applies AES encryption with JavaScript on your device, and the ZIP File Converter unpacks RAR, 7z, and TAR variants with a WebAssembly engine the same way. Your files and your password never leave the machine.
Which of these tools contact a server, and which do not? The file tools, meaning both ZIP tools and the File Metadata Viewer, run entirely on your device with nothing transmitted. The YouTube Channel ID Finder is a lookup, so the handle or URL you type is sent through our server to the YouTube API and only that text travels. The Phone Keypad Converter is pure local JavaScript.
What can the File Metadata Viewer tell me? For any file: the real detected type, size, and dates. For photos it reads the full EXIF record, including camera model, settings, and GPS coordinates when present, which makes it the quick way to check whether a photo reveals your location before you share it.
Why would I need a YouTube channel ID instead of the handle? APIs, RSS feeds, embed configurations, and many third-party services want the underlying channel ID that starts with UC, not the friendly @handle. The finder resolves handles, custom URLs, and even video links to that ID.
Are these utilities free with no catch? Yes, free with no limits, watermarks, or accounts, the same as every tool on the site. The odd jobs deserve decent tools too.
