How long do files last on Uguu and what is the maximum upload size?

Updated

Files uploaded to Uguu expire 3 hours after upload, and the maximum upload size is 128 MiB per file. Those two limits come directly from the site's own notice ("Max upload size is 128 MiB & files expire after 3 hours"), so if your file is larger than 128 MiB or needs to stay online longer than 3 hours, Uguu is not the right tool for that job.

The two limits at a glance

Limit Value What it means for you
Maximum upload size 128 MiB A single file above this size cannot be uploaded.
File lifetime 3 hours After 3 hours the file expires and can no longer be accessed.

Both numbers are stated on the Uguu homepage, so they are the current published limits rather than estimates.

What "expires after 3 hours" actually means

Uguu is a temporary file host, not storage. The 3-hour window is the whole point of the service: you upload a file, share the link, and the file disappears on its own.

Practical consequences:

  • The clock starts at upload. The 3 hours is counted from when the file is uploaded, not from when someone first downloads it.
  • After expiry, the link stops working. Once the file is gone, it cannot be retrieved or "renewed" — the only option is to upload it again, which starts a fresh 3-hour window.
  • There is no account to log into. Uguu's description says it works with no account sign-up, so you cannot manage, extend, or recover files from a dashboard. The link is your only handle on the file.

When Uguu fits and when it doesn't

Uguu works well when the file is small and the need is short-lived. For example:

  • Sending a screenshot or a PDF to someone in a chat, where they will open it within the next hour or two.
  • Handing off a music or video clip that is under 128 MiB for a quick review.
  • Sharing a document temporarily without creating an account on a permanent cloud service.

It is a poor fit when:

  • The file is larger than 128 MiB — it simply will not upload.
  • The recipient may not open the link for more than 3 hours — by then the file is gone.
  • You need the file to stay available for days, weeks, or as a permanent archive.

For those cases you need a host with a longer retention window or a larger size cap, or a permanent storage service.

Checking the limits before you rely on them

Limits on free services can change. The authoritative place to confirm the current numbers is the Uguu homepage itself, which displays the max upload size and expiry time. The site also links to an FAQ and a status page, which are worth a look if you are planning to use it for anything time-sensitive.
