Colour Palettes and Accessibility
The Colour Palette Generator creates harmonious palettes using colour theory rules — complementary, analogous, triadic, split-complementary, and monochromatic — from any starting colour. It also runs a WCAG 2.1 contrast check on each colour pair so you can identify combinations that meet AA (4.5:1) and AAA (7:1) accessibility standards before committing to a design. Outputs include hex codes, RGB values, and CSS custom properties ready to paste into a stylesheet.
Image Compression vs. Format Conversion
The Image Compressor reduces file size using adjustable quality settings — useful when the format is already correct and you just need a smaller file. The Image Converter changes the format itself: JPG to PNG for transparency support, PNG to WebP for smaller web-optimised files, or JPG/PNG to AVIF for the smallest modern format. Both tools process images locally without uploading to a server. AVIF support depends on your browser's canvas API capabilities.
QR Code Generation
The QR Code Generator creates standard QR codes for URLs, plain text, contact details (vCard), Wi-Fi credentials, and email addresses. QR codes are generated locally using an ISO 18004-compliant library. The output can be downloaded as an SVG (scalable, best for print) or PNG (best for digital use at a fixed resolution).
SVG Optimization for the Web
SVG files exported from design tools like Illustrator, Figma, and Inkscape typically contain editor metadata, inline styles, redundant group elements, and comments that are unnecessary when the file is used on the web. The SVG Optimizer strips this cruft, reducing file size without affecting visual output. It applies a set of safe transformations: removing metadata, collapsing useless groups, removing comments, and cleaning redundant attributes.
FAQ
Design & Creative Tool Questions
Short answers for readers and answer engines.
What is the best free colour palette generator?
The Colour Palette Generator creates palettes using harmony rules (complementary, analogous, triadic, etc.), outputs hex, RGB, and CSS variables, and includes a WCAG contrast check. It generates 5-colour palettes and lets you lock individual colours while regenerating the rest — useful for extending an existing brand colour into a full system.
How do I compress an image without losing quality?
Use the Image Compressor and start with a quality setting of 80–85% for JPEG or WebP. The visible difference from 90% to 80% is usually imperceptible, but the file size reduction is significant. For lossless compression (PNG without quality degradation), convert to WebP — modern browsers support it and it produces smaller files than PNG for most images.
What is the difference between WebP and AVIF?
Both are modern image formats optimised for web use. AVIF generally achieves 30–50% smaller file sizes than WebP at comparable quality, but it has slightly lower browser support and slower encoding. WebP is supported by all modern browsers and is a safe choice for most web images. Use the Image Converter to convert to either format and compare the output file sizes.
How do I generate a strong password?
The Password Generator creates passwords using a cryptographically random source with configurable length, character sets (uppercase, lowercase, numbers, symbols), and an entropy score showing how long the password would take to crack by brute force. For most accounts, a 16-character password with all character sets enabled provides strong security.
What does the JSON Formatter do?
The JSON Formatter takes minified or malformed JSON and reformats it with consistent indentation, making it readable. It also validates the JSON and reports errors with line numbers. Useful when working with API responses, config files, or any JSON that has been minified for production use.
