Website thumbnail downloader

Collect every image a pasted page declares, from Open Graph and Twitter cards to favicons and JSON-LD, with real dimensions and failed fetches listed with reasons.

This tool is in beta

Page source

Only have a link? Open the page, view its source, and copy from <head> to </head>.

Paste the head or the whole page, up to 512 KB.

Paste the page source, then press Read the page.

What you get is what the page declares: every lane this tool reads is listed, including the ones that fail, with the reason. Formats and pixel sizes come from the file bytes, never from the file name or the declared size, so a mislabeled image shows the mismatch. Logos and icons are often trademarks, and a publicly reachable image is not automatically yours to redistribute: download only what you own or have permission to use. Hosts that refuse browser requests cannot be read here, and that refusal is reported rather than worked around.

Read options

Optional; resolves relative image addresses
Off: list what the page declares, nothing leaves this tab.

What leaves your browser

With fetching on, your browser requests each declared image and the page's own manifest, straight from their hosts. With it off, nothing leaves this tab. This page leaves your browser only when you press the button; never on load, never in the background. Nothing is sent anywhere else. Google Analytics still measures the visit to this page, and it never receives what you run through this tool.

Runs on this device. Nothing is uploaded.
