What is YouTube Thumbnail Downloader?

The YouTube Thumbnail Downloader reads a public video ID, checks the official default, medium, high, standard, and maxres thumbnail URLs, and downloads an available JPEG without downloading the video itself.

How to download YouTube thumbnails in every available size

Paste a public YouTube video URL or ID, check the five official thumbnail variants, and download only the sizes that the video actually provides.

The five official thumbnail variants

YouTube exposes default (120×90), medium (320×180), high (480×360), standard (640×480), and maxres (normally 1280×720) variants. Standard and maxres are optional, so the tool checks them instead of showing a broken download.

A 4K video does not have a 4K thumbnail

The official maximum-resolution thumbnail is normally 1280×720 even when the uploaded video is 2160p. The tool labels that image as maxres rather than making a misleading 4K claim.

Supported links and safe downloads

Regular watch URLs, youtu.be links, Shorts, Live links, embed URLs, privacy-enhanced embeds, and bare 11-character IDs are accepted. The server validates the ID and fetches only a fixed YouTube image host.

Public metadata, requested only for this lookup

The pasted URL is sent to the ProntoUso server for one request, then public metadata and images are read from YouTube. Nothing is stored. Preview images are delivered through this site's same-origin image route, and copyright still belongs to the relevant owner.

Frequently Asked Questions

Why is maxres unavailable for some videos?

YouTube only creates that variant for some videos, usually when the source and thumbnail support HD output. The tool verifies availability before enabling its download button.

Can I download a 4K YouTube thumbnail?

Not through the official thumbnail variants: maxres is normally 1280×720. A 4K video resolution does not mean YouTube publishes a 3840×2160 thumbnail.

Can I reuse someone else's thumbnail?

Only when you have the necessary permission or another valid legal basis. Download availability does not grant copyright or reuse rights.
