1. JSON Formatter
Pasting a minified API response to read it is one of the most common developer tasks. Our JSON Formatter turns a single line of dense JSON into a properly indented, colour-coded structure in one paste. No copying to an IDE or writing a one-off script needed.
2. JWT Decoder
Debugging authentication issues often means checking what's actually inside a token. Our JWT Decoder shows you the header, payload, and all claims — including the issued-at and expiry timestamps — without needing to write decoding code.
3. JSON Diff
When something breaks after a deployment and you suspect a configuration change, our JSON Diff tool shows every added, removed, and changed value between two JSON documents. It's structure-aware, so key reordering doesn't produce false positives the way a plain text diff would.
4. JSONPath Tester
Extracting specific values from a complex nested API response normally means writing code, running it, tweaking, and repeating. Our JSONPath Tester lets you write and test path expressions interactively against real data without touching a code editor.
5. JSON Schema Generator
Documenting an API response by writing a schema by hand is tedious and error-prone. Paste a real example response into our Schema Generator and get a complete, accurate schema in seconds.
6. JSON to TypeScript
When you're consuming a new API in a TypeScript project, our JSON to TypeScript tool generates matching interfaces from a sample response. A task that used to take several minutes now takes seconds.
7. Image Converter
Before a deploy, converting assets to WebP or AVIF makes a measurable difference to page load time. Our Image Converter handles the most common format conversions in the browser with a quality slider for fine control.
8. PDF to Text
When you need the text content of a PDF document without copying it page by page, our PDF to Text tool extracts everything in one step — useful for feeding document content into other tools or processes.
9. Base64 Encoder
Constructing a Basic Auth header, embedding a small image as a data URL, or decoding a token segment are all common one-off tasks. Our Base64 tool handles encode and decode instantly without any setup.
10. JSON Generator
Creating realistic test data by hand is slow and the results are usually too uniform to catch edge cases. Our JSON Generator creates realistic mock records with names, emails, UUIDs, dates, and more — as many as you need, immediately.
Frequently Asked Questions
- Are all these tools completely free?
- Yes — every tool on BeYourTools is free with no account required and no usage limits. All processing happens in your browser and nothing is uploaded to any server.
- Do these tools work on mobile?
- Yes. All tools are fully responsive and work on phones and tablets. Some tools with complex interfaces are easier to use on a larger screen, but nothing is restricted to desktop.
- How are these tools different from running code locally?
- They require no setup, no dependencies, and no environment configuration. For one-off tasks during development, opening a browser tab is faster than writing a script, running it, and cleaning up.
