Image Converter API

healthy 4,255 Subscribers

Convert, resize and optimize images between JPEG, PNG, WebP, AVIF, GIF and TIFF — powered by sharp / libvips. Convert a single image to another format with control over quality and dimensions, resize with selectable fit modes, optimize (re-encode) for smaller files with a reported byte saving, and read full image metadata (format, dimensions, channels, alpha, animation, density). Send an image by public URL, base64 or a raw binary request body and receive the result as base64 JSON or, with raw=1, the raw image bytes. Only public http/https URLs are accepted and private or internal hosts are blocked. Pure server-side processing (no third-party upstream). Ideal for upload pipelines, CDNs and thumbnails, WebP/AVIF modernisation and bandwidth optimisation.

Placeholder API

A fast, fully-local SVG generator for mockups and UIs: placeholder images (a sized rectangle with centered text and automatic contrast), initials avatars (with a deterministic colour derived from the name, in a circle or square), and identicon-style symmetric patterns generated deterministically from any seed. Every endpoint returns the JSON envelope or, with raw=1, the raw SVG so the URL can be used directly as an image source. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for prototypes, dashboards, user avatars, empty states and design systems.

Image API

Inspect image metadata (dimensions, format, size, colour space, transparency) and resize or convert images between JPEG, PNG, WebP and AVIF straight from a URL. Perfect for thumbnails, format optimisation and on-the-fly image transforms.

QR Code API

Generate QR codes on demand as a base64 PNG, an SVG, or a raw embeddable image. Customise size, quiet-zone margin, error-correction level and foreground/background colors. Encode URLs, text, Wi-Fi, vCards and more.

YAML API

Convert, validate and tidy YAML through a fast, fully-local API. Turn YAML into JSON (including multi-document streams) or JSON into clean YAML with optional key sorting and custom indentation, validate a document and get the exact line and column of any syntax error with a context snippet, or reformat and normalize existing YAML. Inputs can be sent as a raw text/plain body, a JSON field or a query parameter; outputs are tidy JSON. Pure server-side compute with no third-party upstream, so responses are instant and the service is always available. Ideal for DevOps and CI/CD, configuration and infrastructure-as-code tooling, no-code platforms, editors and data pipelines.
