Files

Host a file, get a link that never changes

Files lives in the same workspace that delivers your images. Put files into a collection, make the collection public, and every file in it gets a permanent link you can paste anywhere — a deck, a press kit, a product image, a download.

Collections and links

• A collection is a folder. It is created restricted: nothing in it is served until you make it public.
• A public collection gives every file in it a link of the form https://files.cdn.mn/f/<file-id>. Anyone who has the link can open the file — treat an open link like a published URL.
• The link is the file’s id, not its name. Rename the file or move it to another collection and the link keeps working.
• Making a collection restricted again stops every link in it on the next request — typically within seconds, always within minutes. The dashboard shows a file as “still being removed” until its link has stopped.

Uploading

Open Files in your workspace, open a collection, and drop files in or choose them. Uploads run one after another and each file is checked before it is stored:

• Size: up to 25 MB per file, on every plan.
• Types: JPEG, PNG, WebP, AVIF and GIF images; PDF; Word, Excel and PowerPoint (the modern .docx/.xlsx/.pptx formats) and OpenDocument files; zip archives.
• Decided by content, not by name. What a file is gets read from its bytes. A renamed HTML file or executable is refused, and a PDF with junk in front of it is refused as well.
• Not accepted yet: SVG (it can carry script), the legacy Office formats (.doc/.xls/.ppt, which can carry macros), and plain text or CSV. Convert an SVG to PNG or WebP; save a legacy Office file in its modern format.

Files are served with headers that tell browsers exactly what they are and never to guess, and documents that are not images or PDFs are offered as downloads rather than opened in the page.

Storage per plan

Each plan includes a fixed amount of file storage. When the workspace reaches it, uploads pause until you delete something or move to a larger plan; existing files keep serving. Deleting a file frees its space right away.

Early-stage startups get a paid plan free for a year through the startup programme, file storage included. The Files overview is the shorter, non-technical version of this page.

Deleting

Delete a file from its collection, or delete an empty collection. A deleted file’s link stops on the next request and the bytes are removed from storage within minutes. There is no trash: keep your own copy of anything you may need again.

Agents

An AI agent can do the same through the MCP server with the files:read, files:write and files:publish scopes: list collections and files, create a collection, upload a file (as base64, up to 8 MB per call), and make a collection public or restricted. Publishing is a sensitive action — it waits for your approval on the workspace’s Agents page unless you granted the agent autonomy for it. See the agent guide.

What is next

Gated sharing is in development: share links that ask the recipient to verify an email and accept your agreement before they see the files, expiry and revoke per link, and a log of who opened what. Until then, keep confidential material in a restricted collection.
