What Is Uguu? A Free Temporary File Hosting Service

Uguu is a free, no-account temporary file hosting service at uguu.se. You drop or paste a file into the page, get a link, and share it. Two limits define how you can use it: the maximum upload size is 128 MiB, and files expire after 3 hours. If your file fits those bounds and you only need a short-lived link, Uguu works without sign-up, ads, or tracking. If you need longer retention or larger files, it is the wrong tool.

How Uguu works

The service is deliberately minimal. There is no dashboard, no file manager, and no account to configure.

1. Open uguu.se. The page presents a drop area with the prompt "Drop or paste file(s)."
2. Add your file by dragging it onto the page or pasting it from your clipboard.
3. Upload and copy the link. Uguu returns a URL you can send to anyone.
4. Share it within the window. The recipient must download the file before the 3-hour expiry.

The expected result is a direct link to the file, not a gallery or preview page. Once 3 hours pass, the file is gone and the link stops working — there is no recovery.

Key characteristics

The donation options matter for context: Uguu states that hosting costs are not free and that donations keep the service alive, ad-free, and fast. That is a sustainability model, not a paywall — nothing on the page indicates a paid tier or a login requirement.

When to use it — and when not to

Good fits:

• Sending a file to someone in a chat or email where a permanent link is unnecessary or unwanted.
• Quick handoffs of a screenshot, PDF, or audio clip under 128 MiB.
• Situations where you do not want to create an account or leave a persistent copy online.

Poor fits:

• Anything you need available tomorrow — the 3-hour expiry is absolute.
• Files above 128 MiB.
• Material you need to manage, delete, or re-download later; there is no account interface for that.
• Sensitive files where you need control over deletion timing. The file disappears on schedule, but you cannot remove it early through a dashboard.

Practical notes

• Plan around the clock, not the calendar. Three hours is short. If the recipient is in a different time zone or may not check messages promptly, confirm they can download before you rely on the link.
• Re-upload rather than re-share. If a link expires, the only fix is uploading the file again and sending a new URL.
• Check the size before uploading. A 128 MiB cap rules out most full-length video files and many RAW photo sets. Compress or split first if you are near the limit.
• There is an API and an FAQ. The site links to both, plus a status page and a GitHub repository, which is useful if you want to automate uploads or check whether the service is currently up.

Uguu is best understood as a disposable link generator: fast, anonymous, and temporary by design. Use it when "temporary" is exactly what you want.
