Cover art downloader
Pull the artwork off a public song page, then re-render it at the size and file format you actually need — thumbnails for a list, 1600px for a upload, WebP for the web.
Cover art
A public song page works, and so does a direct link to the image file. Everything is fetched through this site's own proxy, then redrawn locally on a canvas.
Mixed song links and image links are fine. Duplicates are dropped before anything is fetched.
How it works
The tool never re-hosts anything. It asks this site's proxy for the bytes of one image, draws them into an offscreen canvas at the size you picked, and asks the browser to encode that canvas as JPEG, PNG or WebP. The file that lands in your downloads folder was produced on your machine, from pixels your browser already had.
- Original keeps the exact pixel dimensions that came back from the server — no resampling at all.
- 1600 / 1200 / 800 / 500 / 256 scale the longest edge to that number and keep aspect ratio, so square covers stay square.
- JPEG is encoded at high quality over a white backdrop, which matters if the source has transparency. PNG is lossless and keeps alpha. WebP is usually the smallest of the three at comparable quality.
Batch mode runs the same pipeline in a loop and collects the results into a ZIP built in memory with JSZip. Failures do not stop the run — a link that cannot be resolved is marked in the list and the remaining covers still make it into the archive.
Practical notes
- Upscaling past the source resolution is possible but pointless — a 500px cover asked to become 1600px just gets soft. Check the Source stat before you pick a size.
- For streaming-platform uploads, 1600px JPEG is the safe default. For a site or a docs page, 800px WebP is usually a tenth of the weight.
- Only cover art from pages you have the right to use should be re-published. The tool is for your own songs, review material and archival copies.
- If a link resolves but the preview stays blank, the server likely returned an HTML error page instead of an image. Open the link directly to confirm it is public.
FAQ
Can I give it a song page link instead of the image?
Yes. Song links are resolved first: the page is read through the proxy, the cover URL is pulled out of its metadata, and that image is fetched. A direct image link skips that step entirely.
Why is my JPEG bigger than the original file?
Because it is a re-encode, not a copy. The source may have been compressed harder than the browser's encoder does. Pick Original plus PNG only when you want fidelity; pick WebP when you want the smallest file.
Does batch mode have a limit?
No hard limit, but the whole ZIP is assembled in memory, so a few dozen covers at 1600px is a sensible ceiling on a typical laptop. Split larger jobs into runs.
Is the image uploaded anywhere?
No. The proxy fetches the bytes and hands them straight to your browser; resizing, encoding and zipping all happen in the page. Nothing is stored server-side.
