Builds and uploads

Upload limits and file types

Limits are enforced twice — in the browser and again in the upload worker — and the two do not agree for media. This page is the authoritative table.

Size ceilings

CategoryClient (browser)Worker (authoritative)
game-build5 GiB5 GiB
game-web5 GiB total for the folder, 5 GiB per file5 GiB per file — no folder total
app-file5 GiB5 GiB
app-media5 GiB250 MiB
Important: The media mismatch is the one to know: a 400 MB trailer passes the browser check and is rejected by the worker with File is too large for this upload category. Keep media under 250 MB. Separately, the 2 MB icon and 15 MB feature-graphic figures are guidance written in Studio's labels, not transport limits.

Plans do not change the ceiling

FREE_MAX_FILE_SIZE and STARTER_MAX_FILE_SIZE are both 5 GiB, so the plan check in the uploader is currently inert: a paid plan buys no extra headroom on a single file. Studio's own comment still describes "1 GB free / 5 GB Starter", and a dashboard error reads File is larger than your … upload limit. — but the enforced number is 5 GiB either way.

Note: Do not size a release to 1 GB to stay on a free tier. That tier no longer exists in the code, and nothing enforces it.

Allowed extensions

For builds, app files and web zips the allowlist is:

  • Media slots are narrower: PNG, JPEG, WebP, MP4 — anything else returns App media must be an image or MP4 video.
  • Web-game folders skip the allowlist entirely and are checked only against the denylist, so .css, .svg, .ttf, .woff2 and .unityweb are accepted.
  • Double extensions such as .js.br and .data.gz are reduced to the final extension before the test.
  • File names are normalised with NFKD, every character outside [\w.-] becomes _, and names are truncated hard at 140 characters.
.apk  .aab  .zip  .html  .js  .wasm  .data  .json  .png  .jpg  .jpeg  .webp  .mp4
Watch out: The MIME table in the uploader knows about 30 more types — .gif, .svg, .ico, .webm, .mp3, .otf — that the build allowlist will reject. Do not infer from "it picked a content type" that the file is uploadable.

The denylist

These are refused everywhere, in every category, including inside a web-game folder:

  • The message is Blocked file type: <ext> in the browser and Blocked file extension: <ext> in the worker; for folder contents, Blocked file type in web game folder: <ext>.
  • .exe and .msi are blocked, which is why a Windows build must travel as a .zip — see Windows builds.
  • .ipa and .xapk are blocked, so there is no iOS route and no sideload-bundle route.
  • .rar is blocked: always use .zip.
.php  .exe  .sh  .bat  .cmd  .ps1  .msi  .dmg  .jar  .com  .scr  .vbs  .app  .xapk  .ipa  .rar

Web-game folder rules

The folder picker enforces three extra checks on top of extension rules:

CheckMessage
The picker expects an exported web build, not a stray fileChoose your exported web game folder.
index.html must be in the folderWeb game folder must include index.html.
No path may escape the folder rootWeb game contains an unsafe file path.
Cumulative size must remain under 5 GiBWeb game is too large (X). Max 5.00 GB.
Note: Sub-folders are preserved in the object key, so a Unity or Godot export with Build/ and TemplateData/ directories lands intact. The served root is storage.appsinity.com/public/games/{gameId}/web/{version}/.

Frequently asked questions

Why did my 1.2 GB game fail when the label said 1 GB free?

It should not have: 5 GiB is enforced in both layers today. The failure text quotes a plan ceiling that no longer exists in code, so read the byte count in the message, not the sentence.

Is there a per-project storage quota?

None is enforced in the upload path. The only ceilings are per file and, in the browser only, per web-game folder.

Can I upload a .zip of .apk files?

Technically yes, and it is a mistake — the store's download chain looks for a package, not an archive, and nothing will unpack it for an Android player.
