Private & secure

Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.

The picture behind your link

When someone shares your link on Facebook, LinkedIn, X or Slack, the preview card comes from your page's og:image — and a strong card noticeably lifts click-through. This generator builds one at the exact 1200×630 size, with an auto-wrapping title, a subtitle, an eyebrow badge and a choice of gradient themes.

Download the PNG, host it alongside your site, and point og:image (and twitter:image) at it. The card is drawn on a canvas in your browser, so nothing is uploaded. Need a matching background fill? Try the Gradient Generator.

Frequently asked questions

Your files never leave your device

Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.

No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
