All Utility tools

Encode, decode, hash, convert timestamps, and handle everyday Android-adjacent tasks.

Encode/Decode

Convert text with base64, hex and URL encoding in either direction.

Hash

Compute MD5 and SHA hashes of any text or file you drop in.

Epoch

Convert Unix timestamps to readable dates and back again.

Converters

Convert px, dp and sp, classify DPI buckets, and compute PPI.

Quick conversions without the noise

These are the utilities you use a dozen times a day and never want to think hard about: decoding a base64 blob, URL-encoding a query string, hashing a file to verify it, turning a Unix timestamp into a real date, or converting pixels to dp. Each one updates as you type and keeps the math out of your way.

Everything runs locally in your browser, so the text and files you process are never uploaded. Install the site as a Progressive Web App and these converters stay a tap away, online or off.
