Developer Utilities for Everyday Coding Tasks
Converting between binary, hex, and octal by hand? Let these tools do it instantly. Sort lines, remove empty rows, encode/decode data — everything developers and analysts need to clean and transform raw data fast.
In software development, small details consume time. Generating UUIDs, Base64 encoding, or cleaning JSON are tasks you now do in a second. Local tools made by developers for developers.
Atbash Cipher
Encode and decode text using the Atbash cipher that reverses the alphabet.
Base Converter (2-64)
Convert numbers between any base from 2 to 64.
Base32 Encoder/Decoder
Encode text to Base32 or decode Base32 back to text using RFC 4648.
Binary ↔ String Converter
Convert between binary code and plain text.
Text ↔ Decimal Converter
Convert between decimal code and plain text.
Empty Line Remover
Remove all empty or blank lines from text.
Generate Fake Test Data
Generate realistic mock data for testing with multiple schemas and export formats.
Hex ↔ String Converter
Convert between hexadecimal and plain text.
Convert Image to Base64
Convert images to Base64 with multiple output formats: data URI, CSS, HTML, and Markdown.
Convert JSON to CSV
Transform JSON data into CSV format with nested object flattening and table preview.
Line Sorter
Sort lines of text alphabetically, numerically, by length, etc.
Generate Markdown Tables
Create markdown tables with an interactive grid editor, column alignment, and CSV import.
Text ↔ Octal Converter
Convert between octal code and plain text.
ROT13/ROT47 Encoder
Apply ROT13 or ROT47 cipher to encode and decode text instantly.
Pick a utility
UUID generators, Base64 encoders, hash calculators, JSON formatters: each tool does one thing well. Scroll through the list or use the search bar on the homepage to jump to the exact utility you need.
Provide your input
Paste the string, file content, or raw bytes. Most tools auto-detect encoding where possible. If the input is invalid the tool will tell you immediately rather than producing garbage output.
Get your result instantly
Processing is synchronous and local. Even hashing large strings takes milliseconds because the Web Crypto API is hardware-accelerated on most modern browsers. The output appears right below the input.
Integrate into your workflow
Copy the result into your terminal, your code editor, or your CI/CD config. These tools are designed to replace those random Stack Overflow one-liners you keep bookmarking. They are always here; they always work the same way.
Full-Stack Developers in Daily Workflows
Generating a UUID for a database seed, encoding an image to Base64 for an email template, hashing a string to verify an API signature: these micro-tasks pop up constantly. Having them all in one place, locally, with no rate limits, means you stop context-switching to random websites.
DevOps Engineers Debugging Pipelines
When a CI/CD job fails because of a malformed environment variable or an incorrect encoding, you need a quick way to decode, re-encode, or hash the value to match what the pipeline expects. These tools do that in seconds.
Security Auditors Verifying Hashes
Checking that a file hash matches the one published by a vendor is a basic security practice. Our hash calculator supports SHA-256, SHA-512, and other algorithms. Drop the file, compare the output, move on.

Yes; all of them, with no sign-up and no rate limits.
Everything processes locally in your browser. We do not log inputs, outputs, or any metadata about your usage. Your code stays on your machine.
MD5, SHA-1, SHA-256, and SHA-512. All are computed using the Web Crypto API, which is hardware-accelerated on most devices. For security purposes, prefer SHA-256 or SHA-512; MD5 and SHA-1 are provided for legacy compatibility.
The UUID generator creates one UUID at a time. Click the generate button repeatedly or use the bulk mode if available. Each UUID is a Version 4 random UUID generated with cryptographic randomness.
Yes. The interfaces are responsive and work on phones and tablets. Some tools with large input areas are more comfortable on a desktop, but they function correctly on any screen size.
Yes. The Base64 encoder accepts both text input and file uploads. For files, it reads the binary content and produces the Base64 string. Be aware that Base64 encoding increases the data size by approximately 33%.
Yes. The hex-encoded output matches what you would get from sha256sum, md5sum, or similar CLI tools. You can use our tool to verify hashes generated elsewhere or vice versa.
