Developer Tools
Format JSON, encode Base64, generate QR codes, build strong passwords and pick colors. Lightweight browser tools for developers and power users.
What are online developer tools?
Online developer tools are on-device utilities for common programming, design, and technical tasks. From formatting JSON data to generating QR codes and creating strong passwords, these tools handle the repetitive tasks that developers, designers, and technical users encounter daily. Every tool runs on your device with no installation, no account, and no data transmission.
Most popular developer tools
The JSON Formatter validates, formats, and minifies JSON data instantly, making it essential for API debugging and data inspection. The Base64 Encoder and Decoder converts text and files to Base64 strings and back, commonly used in authentication, email encoding, and data URIs. The QR Code Generator creates scannable QR codes for URLs, text, phone numbers, and more. The Password Generator creates cryptographically strong passwords with customizable length and character sets.
Common use cases
Paste a minified or malformed API response into the JSON Formatter to validate its structure and reformat it for readability — a routine task when debugging REST or GraphQL endpoints. Encode an image or binary payload to Base64 for embedding in a CSS data URI or an email MIME part, then decode it back to verify the round-trip was clean. Generate a QR code for a landing page URL and drop the downloaded PNG directly into a print flyer, presentation slide, or product label. Create a strong, random password for a new service account or shared credential using the Password Generator, which relies on the browser's own Web Crypto API — the result is never transmitted anywhere. Sample exact pixel colors from any image in HEX, RGB, or HSL using the Color Palette & Picker when you need to match a design spec without guessing.
How to use these tools
Paste your input, adjust settings if needed, and copy or download your result. Most developer tools produce output instantly as you type. No account required, no watermarks. Tools work across all modern browsers on desktop and mobile.
Privacy and security
All processing happens locally on your device. JSON data, Base64 strings, passwords, and QR code content are never transmitted to any server. This makes PixMidas developer tools safe for sensitive API keys, authentication tokens, and confidential data structures.
Which developer tool do you need?
Use the JSON Formatter to validate and clean API responses. Use the Base64 tool to encode or decode strings. Use the QR Code Generator to create scannable codes for any content. Use the Password Generator to create strong, secure passwords instantly. Use the Hash Generator to compute MD5, SHA-1, SHA-256, or SHA-512 digests for text or files. Use the URL Encoder and Decoder to percent-encode and decode URLs and query strings, or parse a URL into its component parts.
Frequently asked questions
Does the JSON formatter send my data anywhere?
No. JSON parsing and formatting runs entirely on your device using JavaScript's built-in JSON.parse(). Your data is never sent to any server. This makes it safe to paste API responses, config files, and private data for formatting.
What formats does the QR code generator support?
The QR code generator creates codes for plain text, URLs, email addresses, phone numbers, and SMS messages. The output is a PNG image you can download and use in print or digital materials.
How secure are passwords generated by the password generator?
The password generator uses the browser's built-in Web Crypto API (crypto.getRandomValues) for cryptographically secure randomness. Generated passwords are not transmitted anywhere and exist only temporarily in memory.
