4chan image search
Find every archived 4chan post of an exact image. Drop the file below: its MD5 fingerprint is calculated in your browser and looked up on the archives. Nothing is uploaded to this site.
or paste a hash:
What it finds - and what it doesn't
It finds identical files: the same image someone downloaded and reposted. It will not find crops, screenshots or resized versions, because any change produces a different fingerprint. For look-alike images, use a general reverse image search such as Google Lens or Bing Visual Search and add the archive domain to your query.
FAQ
How does 4chan image search work?
Every 4chan image has an MD5 fingerprint, and archives store it with each post. This page computes the fingerprint of your file inside your browser and searches for it on each archive. The image never leaves your device.
Why does my image return no results?
Exact matching only works on the identical file. Screenshots, crops, resizes and re-saved copies all have different fingerprints. Try a general reverse image search such as Google Lens for look-alike images.
Can I search by the MD5 shown on 4chan?
Yes. Paste the base64 MD5 (24 characters, ending in ==) or a 32-character hex MD5 into the hash box.
