Web & Social Media Tools

Build QR codes in the browser: URL, text, mailto, tel:, SMS (sms:), WhatsApp (wa.me), geo: coordinates, Wi‑Fi join strings, or vCard 3.0. Pick size 128–1024 px, error correction L–H, colors; copy payload, copy PNG, or download PNG/SVG. Tabbed UI with icons; custom strings via Text — no upload.

Render linear barcodes in the browser: CODE128, CODE39, EAN-13 (12 digits), EAN-8 (7), UPC (11), ITF14, MSI, pharmacode, or codabar. Tune bar width, height, human-readable caption, font size, line/background colors, and quiet margin; live canvas preview with debounce. Download barcode.png or barcode.svg, or copy the image — no upload.

Create short links that open on this site at /s/{code} and redirect to your destination. POST the long URL with optional custom alias (letters, digits, _ and -) and expiry (never, 1, 7, or 30 days). Copy the public short URL, scan an on-page QR, and view click counts plus recent referrers via stats lookup.

Capture public http(s) pages on the server: viewport presets (desktop, laptop, tablet, mobile) or custom width/height, 1× or 2× device scale, full-page vs viewport, PNG/JPG/PDF output, and 0–3 s post-load delay. POST to the screenshot API, preview images in the page, download or copy when supported — typically a few seconds; requires headless browser support on the backend.

Strip HTML to plain text or wrap plain text as HTML in the browser: HTML→Text with DOMParser, optional preserved line breaks, links as Markdown [label](url), and collapsed blank lines; Text→HTML with <p> blocks, optional <br>, auto-linked https URLs, entity escaping, copy/download .txt or .html, and optional sandboxed preview.

Turn HTML <table> markup into an .xlsx workbook: paste HTML, fetch a public https page via server proxy, or upload .html/.htm (2 MB). Detect multiple tables with colspan/rowspan handling, toggle headers and separate vs combined sheets, then export tables.xlsx locally in the browser.

Batch-check up to 50 http(s) links: paste one URL per line or extract unique URLs from pasted text/HTML, POST to the link-check API, and see OK, redirect, broken, or timeout with status code, response time, and final URL. Filter and sort the table, export link-check-results.csv in the browser, or re-run checks on broken/timeout URLs only.

Free on-page and technical SEO check for one URL at a time — meta tags, headings, images, links, Open Graph, JSON-LD, and more. We do not include backlinks, keyword rankings, or full-site crawls (those need separate databases). URL mode: server HTML fetch + in-browser audit; optional PageSpeed from Google (capped per browser per day). Paste HTML: 100% in your browser.
