## Tools

- [Accessibility Audit Report Generator](https://elysiatools.com/en/tools/accessibility-audit-report-generator): Audit HTML or a URL for common WCAG issues and export a structured PDF report grouped by severity
- [API Request Code Snippet Generator](https://elysiatools.com/en/tools/api-request-code-snippet-generator): Generate cURL and common language code snippets from a request URL, method, headers, query parameters, and body
- [Batch URL Validator](https://elysiatools.com/en/tools/batch-url-validator): Validate multiple URLs at once with format checking and security analysis
- [Bulk URL/Link Extractor](https://elysiatools.com/en/tools/bulk-url-extractor): Extract all HTTP/HTTPS links from text with deduplication and export options
- [Color Palette Extractor from Image URL](https://elysiatools.com/en/tools/color-palette-extractor-from-image-url): Fetch a remote image URL, extract dominant colors, export code-ready palette files, and review contrast ratios
- [Data URI Generator](https://elysiatools.com/en/tools/data-uri-generator): Convert files into Data URIs (Base64 or percent-encoded) for inlining images, fonts, and assets directly into HTML, CSS, or Markdown
- [Domain Extractor](https://elysiatools.com/en/tools/domain-extractor): Extract domain names from URLs. Supports various extraction options including subdomains and path analysis.
- [Heading Hierarchy Auditor](https://elysiatools.com/en/tools/heading-hierarchy-auditor): Audit heading structure from a live URL or pasted HTML, then flag skipped levels, multiple h1 usage, style-only heading abuse, and title metadata drift
- [Image Source Extractor](https://elysiatools.com/en/tools/image-source-extractor): Extract image URLs (src attributes) from HTML source code. Supports lazy-loaded images and srcset attributes.
- [JSONPath REPL Playground](https://elysiatools.com/en/tools/jsonpath-repl-playground): An interactive JSONPath REPL that runs multi-step query pipelines against any JSON. Write one JSONPath expression per line (e.g. $..book\[?(@.price<10)\] then $\[0:5\]) and see each step's matches with counts, paths, and values — plus a shareable URL that encodes your data and pipeline. Supports recursive descent ($..), wildcards (\[*\]), filters (\[?(@.price<10)\]), slices (\[0:5:2\]), and negative indices.
- [PDF Link Annotator](https://elysiatools.com/en/tools/pdf-link-annotator): Automatically convert URLs and chapter references into clickable external/internal links
- [PKCE Code Verifier & Challenge Generator](https://elysiatools.com/en/tools/pkce-code-verifier-generator): Generate, validate and verify OAuth2 / OIDC PKCE (RFC 7636) code_verifier and S256 code_challenge pairs. Three modes: (1) generate a fresh verifier + challenge from cryptographically secure random bytes at 256/384/512/768-bit entropy, (2) audit a verifier you already have against the RFC — length (43–128), charset \[A-Za-z0-9-._~\] and ≥256-bit entropy, and (3) verify a verifier/challenge pair by recomputing BASE64URL(SHA256(verifier)). Optionally build the full authorization-request URL and token-exchange body. Complements the generic nonce-generator (which only emits a verifier+challenge pair) with RFC-compliance auditing and pair verification.
- [Punycode Decoder](https://elysiatools.com/en/tools/punycode-decoder): Decode Punycode (ASCII) domain names to international domain names (IDN)
- [Punycode Encoder](https://elysiatools.com/en/tools/punycode-encoder): Encode international domain names (IDN) to ASCII (Punycode)
