Uploading files

You need to be logged in with a verified email to upload.

What you can upload

Formats	PNG, JPEG, GIF, SVG, WebP
Max size	50 MB

The engine detects the real format from the file's content (magic bytes), not its extension — so a mislabeled file (say a PNG renamed .svg) is caught and corrected on upload.

Filenames

• Up to 200 characters.
• Letters, numbers, spaces, and -, _, . — no slashes.
• Can't begin or end with a dot or a space.
• Unique ignoring the extension: you can't have both Logo.png and Logo.svg. Re-uploading the same name replaces the existing file.

SVGs that only carry a viewBox (no width/height) are given sensible dimensions automatically, so they don't render at zero size.

Embedding an uploaded image

Embed a file with the image syntax — just the filename, no File: prefix:

![[Calpheon_skyline.png|thumb|The Calpheon skyline]]

See Images & files for every option (sizing, thumbnails, alignment, link=, galleries). Each file also has a description page at /file/Name showing its metadata, uploader, license, and which pages use it.
