HTML to PDF
Paste or drop HTML and export a clean, print-ready PDF in your browser. Live sandboxed preview renders your markup exactly as-is with inline CSS, then one click paginates it to A4 or US Letter. Nothing is uploaded and no external assets are fetched.
PDF to HTML
Turn a PDF into clean, semantic HTML you can paste into a page, a CMS or an email. pdf.js reads each page's text and rebuilds reading-order paragraphs in per-page sections, 100% in your browser, nothing uploaded. Honest about layout: it recovers text structure, not pixel-perfect design.
HTML Formatter
Beautify or minify HTML in your browser: reindent messy markup, wrap long lines, fix nesting readability, and collapse to production-ready output. Works on full pages and fragments. Nothing is uploaded.
HTML Minifier
Minify HTML in your browser, collapse whitespace, strip comments and shrink page weight while safely preserving pre, textarea, script and style content. Nothing is uploaded.
Markdown Preview
Write GitHub-Flavoured Markdown and see a live, sanitised HTML preview side-by-side, with a formatting toolbar, tables, task lists, and copy-as-HTML. Nothing is uploaded.
Meta Tag Generator
Generate perfect SEO meta tags, Open Graph and Twitter Card markup with a live Google snippet and social-card preview, copy the ready-to-paste <head> code, 100% in your browser.
Meta Tag Analyzer
Paste a page's HTML to audit its title, description, canonical, robots, Open Graph and Twitter Card tags: with a length score, missing/duplicate checks and a live search & social preview, 100% in your browser.
Twitter Card Generator
Generate Twitter Card meta tags for X with a live card preview. Pick summary or large image, set the title, description, image and @handles, then copy the ready-to-paste twitter:* markup. 100% in your browser.
HTML Sitemap Generator
Turn a list of URLs into a clean, nested HTML sitemap page, a linkable <ul> tree grouped by path that you can paste straight into any site. Boosts internal linking and navigation. 100% in your browser.
HTML Validator
Paste HTML and instantly check well-formedness plus on-page SEO (title, meta description, lang, image alt text and heading order) with a live outline. 100% in your browser.
Meta Tag Validator
Paste your page's HTML and validate its meta tags against SEO best practices: title and description length, canonical, robots, viewport, charset, Open Graph and Twitter completeness: as a graded pass/fail checklist, 100% in your browser.
Heading Checker
Paste your HTML to see the full H1–H6 outline as a tree and catch structural problems (missing H1, multiple H1s, skipped levels and empty headings) with a plain-English fix for each. 100% in your browser.
SVG to HTML
Convert SVG to ready-to-paste HTML in your browser: a clean inline <svg> block, or a self-contained <img> with a data-URI src. Live preview, copy and download, nothing uploaded.
RTF Viewer
Open and read.rtf (Rich Text Format) files right in your browser. Drop or paste an RTF document and see its formatted text (bold, italic, underline and paragraphs) then export clean HTML or plain text. Nothing is uploaded.
JS Rendering Checker
See your page the way AI crawlers see it: without JavaScript. Fetch the raw HTML, count the words that survive, detect client-rendering framework markers, and diff against the rendered DOM to list exactly which content is invisible to GPTBot, ClaudeBot and PerplexityBot.
