All tools

The complete list of BapTools online tools. Everything is free, runs in your browser and requires no account.

Choosing the right tool

Before you start, work out what kind of data you are dealing with. This shortlist should narrow it down:

  • Generating something: QR codes, random numbers, strong passwords, URL slugs.
  • Shrinking a file: images for the web, PDFs for email or uploads.
  • Checking data before you send it: email addresses, URLs and JSON.
  • Converting a format: Base64, HEX to RGB, units of measurement.
  • Quick arithmetic: percentages, discounts, tips.

Why does this run in your browser?

Every BapTools tool processes your data with JavaScript on your own device. Nothing is uploaded, so upload speed and server capacity never come into it, and you can keep working while offline.
