What it does
Free browser-based tools for developers: Base64, URL, HTML, JSON encoding; AES, RSA, DES encryption; JWT decoder; code formatter. No install or login needed.
Free browser-based tools for encoding, decoding, encryption, and code formatting. All tools run entirely in your browser; nothing you enter is sent to a server. Four tools for the encoding and decoding tasks that come up constantly in web development and API work; all client-side, all free. Convert text, JSON, and binary to and from Base64. Supports both standard Base64 and the URL-safe Base64URL variant used in JWTs and OAuth tokens. Handles padding correctly. Encode special characters to HTML entities ( < , & , " , etc.) to prevent XSS, or decode entities back to readable text. Percent-encode URL components and query parameters, or decode encoded strings back. Handles spaces,…from devtoolsstack.com

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years.

Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
