Embed widget

Drop Converter.Plus into any website

One <script> tag and a placeholder gives your readers a fully working image converter — no uploads, no API key, no server.

Files never leave the device

Conversions run entirely in the visitor's browser. No data ever touches our servers.

Tiny loader, lazy engines

The loader is a few KB. Heavy decoders (HEIC, JXL, TIFF) load only when needed.

Works on any site

Sandboxed iframe — no CSS collisions with your page, no script conflicts.

Copy-paste snippets

Add the placeholder where you want the widget to appear, then include the loader once per page (anywhere in <body>). Change the data-converter-plus attribute to switch the conversion pair.

Supported attributes

data-converter-plus="heic-to-jpg" — preselects a specific conversion pair. See the snippets above for the full list.
data-converter-plus="any" — generic image converter that accepts any input format and lets the visitor pick an output (JPG, PNG, WebP, AVIF).

The widget auto-adapts to your page's light or dark color scheme via prefers-color-scheme. The loader is pinned at /widget/v1/ so updates never break existing embeds.
