Embed Inserter von Alexander Shibisty

Embed Inserter — paste, drop, and preview anything in your sidebar

Embed Inserter turns your browser's side panel into a fast, distraction-free preview window. Paste a link, paste a snippet of <iframe> embed code, or simply click or drag a file in — Embed Inserter automatically detects what it is and shows the right preview instantly, without ever leaving the page you're on.

Drop in images, videos, audio, PDFs, documents, code and text files, or embed almost any web page or YouTube/Vimeo video as an iframe. Drop several files or links into the same window at once and they become a lightweight slideshow — auto-advancing at a speed you control, with play/pause and manual prev/next/dot navigation.

Key features

Smart auto-detection for images, video, audio, PDFs, documents, code/text files, and iframe embeds — just paste or drop, no need to pick a type
Multi-item slideshows with adjustable auto-advance speed (1–30 seconds), manual navigation, and auto-hiding controls that stay out of your way until you move the mouse
Split view — two independent preview windows (top and bottom) side by side, with a draggable, keyboard-resizable divider
Per-slide editing — swap out or remove a single slide without disturbing the rest
Image zoom and pan (scroll to zoom, drag to pan), remembered per image
Video loop toggle, remembered per video
Works as a resizable sidebar (Firefox)
Picks up right where you left off — reopens with your last inserted content in each window
Light and dark themes, and a fully localized interface in 54 languages, including automatic right-to-left layout for Arabic, Hebrew, and Persian
No practical file-size limit — local files are referenced, not copied into extension storage

Privacy by design

Embed Inserter only ever stores small metadata (item type, filename, and a reference) in local browser storage — never the contents of your files, and nothing is ever sent anywhere. There is no tracking, no analytics, no remote code: everything runs locally, entirely on your device.
