Manually downloading one thumbnail at a time is fine for one video, painful for 20. Paste a list of YouTube URLs (one per line or comma-separated) and we fetch every thumbnail, optionally convert to PNG/WebP, and bundle them as a single ZIP. Great for research, content audits, or archiving a creator's catalog.
When to use this
Use for: competitor channel audits (download all thumbs from a competitor's top 20 videos), archiving your own thumbs from 5-10 of your videos, building a swipe file of high-CTR thumbnails by niche, sourcing reference images for an A/B test redesign.
Frequently Asked Questions
What's the per-batch limit?
20 video URLs per batch in the free version. Higher batches fetch many thumbnails in parallel and can hit browser memory ceilings, so we cap at 20 for reliability. For larger sets, run multiple batches sequentially.
Can I get thumbnails by channel ID instead of URL?
Not yet - that needs the YouTube Data API which requires an API key. We deliberately don't depend on the API to keep the tool zero-config. Use the channel's video list manually and paste the URLs of the videos you care about.
