Catbox vs Yoink: Which Public File Host Fits Your Links?
Catbox and Yoink both offer anonymous uploads and direct public file links without signup. The real differences are documented retention, account-level file management, and tooling: Catbox publishes a retention policy and a ShareX/API workflow, while Yoink offers a minimal presign-then-PUT flow with no retention promise and no remote deletion.

What they share
Both services let you upload a file in the browser without creating an account and hand you back a direct file URL with no landing page or interstitial. Neither service should be treated as controlled storage for essential business files.
Both also offer optional accounts. On Yoink, Google sign-in attributes uploads to your user ID, but links stay public either way. On Catbox, an account gives you a userhash used for account-level file operations through its API.
Where the difference matters
Retention is the biggest gap. Per its FAQ, Catbox removes anonymous uploads after two years of inactivity or no hits, while account-associated uploads are intended to be permanent subject to its terms and removal policies. That is a documented policy you can read and plan around, not a guarantee. Yoink makes no retention or expiry promise at all, so treat every Yoink link as potentially temporary and keep your original.
Tooling is the second gap. Catbox's tools page documents a ShareX configuration and API file operations using a userhash, so it slots into existing screenshot and upload workflows. Yoink's flow is a presigned URL valid for 900 seconds followed by a single PUT, with a declared size limit of 5 GiB in an API-level check, not a verified operational maximum. There is no public list or delete API and no self-service remote deletion; your Recent Uploads list lives in this browser's localStorage, and clearing it does not remove stored files. See the API docs for the upload flow.
File integrity: the Catbox FAQ states files are served unchanged, with no EXIF stripping or compression, which is a documented policy. On the Yoink side, small synthetic PNG, PDF, ZIP, and MP4 samples uploaded on 14 September 2026 round-tripped with matching SHA256 checksums and MIME types. That is a sample result, not universal proof for all files, so verify integrity yourself if byte-exact delivery matters.
One Catbox caveat: it requires prior approval for commercial-service hotlinking or CDN-style use, which includes ads or otherwise monetized sites. Creators distributing their own creations are fine, but check the FAQ before embedding files in a commercial product.
Which fits
Catbox fits if you want a published retention policy, ShareX integration, and account-level API file management. Yoink fits if you want a one-off public direct link through a simple presign-then-PUT flow, accepting that there is no retention promise, no self-service deletion, and no cross-device library. For business-critical CDN assets or private documents, use dedicated controlled storage instead of either.
