# Toolsly

> Free Online Tools for Images, PDFs, Videos, Audio & Payments.

Toolsly is a free, no-signup collection of 311+ online tools — file converters, encoders, decoders, calculators, lookups, generators. Every tool runs entirely in the user's browser (no upload to a server) unless the tool description says otherwise. Each tool has its own page at `https://toolsly.tools/{slug}` and a machine-readable manifest at `https://toolsly.tools/{slug}/tool.json`.

For LLM agents: a JSON catalog of every tool with input/output schemas and example payloads is available at `https://toolsly.tools/tools.json`. Each per-tool page also embeds JSON-LD with `potentialAction` describing how to invoke the tool. A REST/MCP execution API is planned — for now, tools execute client-side via the web UI at the tool's URL.

## Discovery endpoints

- [`/tools.json`](https://toolsly.tools/tools.json) — JSON catalog of every tool with full schemas
- [`/sitemap.xml`](https://toolsly.tools/sitemap.xml) — every URL on the site
- [`/{slug}/tool.json`](https://toolsly.tools/png-to-jpg/tool.json) — per-tool machine-readable manifest (replace `png-to-jpg` with any slug)
- [`/category/{id}`](https://toolsly.tools/category/image) — category index (image, document, audio, video, text, diagram, color, dev, calc, payment)
