QR & Social

7 free online tools โ€” QR codes, barcodes and social media utilities

Make and read codes, and prepare images for social platforms. The QR generator handles links, text, Wi-Fi access, contact cards and email with PNG and SVG output; the scanner reads codes from your camera or an image without ever auto-opening a link. Barcodes are encoded by hand and verified. For social, resize one image to every platform's format, split a picture into an Instagram grid, or grab a YouTube thumbnail in full resolution.

Codes

  • QR code generator โ€” the general tool, with error-correction and colour options.
  • Wi-Fi QR code โ€” guests join the network with a scan; the password never leaves your browser.
  • vCard QR code โ€” a contact card that saves with a scan, for business cards and badges.
  • QR scanner โ€” camera or image, shows the URL before you decide to open it.
  • Barcode generator โ€” Code 128 and EAN-13 with check digits computed for you.

Social media

The social media image resizer outputs Instagram, Facebook, X, LinkedIn, YouTube, Pinterest and TikTok sizes from one upload, cropping or padding as you choose. The Instagram grid splitter cuts a picture into tiles and names them in posting order โ€” the part everyone gets backwards. The YouTube thumbnail downloader fetches every size straight from YouTube's image servers. The character counter checks a post against every platform's limit.

A note on QR safety

A QR code is just text, usually a URL, and a printed code can lead anywhere. The scanner here never opens a link automatically โ€” it shows you the address first, which is the whole defence against "quishing" stickers on parking meters and menus.
