Takes any long URL and generates a compact, shareable short link. Uses cloud-based processing. Short links resolve through managed providers with automatic failover — free, paced ~10 links/min per address.
Generates real scannable barcodes in UPC-A, EAN-13, Code 128, and Code 39 — JsBarcode encoders with guard patterns, checksums, and start/stop codes, rendered to SVG. Input never leaves your device — everything runs locally in your browser.
Generates random integers within a user-defined min-max range with optional unique and sorted output. Uses the browser random number generator — fine for games, raffles, and sampling, not for security secrets. Input never leaves your device — everything runs locally in your browser.
Scan hundreds of URLs for status codes, redirect chains, and dead pages with CSV export for audits. SEOs check 500 links before a migration — server-side checks with auto-paced backend (~15/min per address).
Crawls any website and generates a standards-compliant XML sitemap. Static-link crawl plus sitemap.xml seeding — JavaScript-rendered links (React, Next.js, Vue) may be missed. Detects broken links and provides SEO health insights.
Click-to-chat link generator (wa.me), group invite link generator, QR code creator for quick connections, chat text formatter (bold, italic, strikethrough), and status text templates.
Enter a phone number (with country code) and a message. The tool generates a wa.me link that opens WhatsApp directly with the message pre-filled.
Yes. Generate QR codes for phone numbers, group invites, or click-to-chat links. Scan with any phone camera to open WhatsApp directly.
No. The analyzer works on text you paste locally. It counts messages per sender, per day, and per hour, plus media and link tallies — it does not do sentiment analysis or word counts, and never touches your WhatsApp account.
Fixed 280px canvas at error-correction level H with margin 2; an optional center logo is drawn at 20% of the size (about 56px at 280px) over the background color. Example: the 280px code encodes https://wa.me/<number>?text=<encoded> for one-tap chat open.
No. All generation and analysis happens locally in your browser. No WhatsApp data is transmitted.
