Uploads and media

Most upload failures come down to one of three things: the file is too big, you’re out of storage, or your session has expired.

Per-file size limits

Section titled “Per-file size limits”

The largest single file you can upload depends on your plan:

Plan Max file size Total storage
Starter 20 MB 1 GB
Booster 50 MB 10 GB
Collector 100 MB 100 GB

An oversized file is rejected before the upload starts, with a message telling you it exceeds your plan’s per-file limit.

Some places in the app apply their own smaller caps regardless of plan:

  • Images placed on a board — 12 MB
  • Images added through image pickers (covers, avatars, and similar) — 15 MB
  • Images pasted or dropped into text editors (wiki pages and other rich text) — 5 MB

If an image is over one of these caps, resize or compress it first — for covers and tokens, anything above these sizes gains you nothing visually.

Out of storage

Section titled “Out of storage”

Everything you upload counts against your plan’s total storage. Check where you stand under Settings → Billing → Storage & usage. To free space, delete assets you no longer use from your asset library, or upgrade your plan.

Supported formats

Section titled “Supported formats”
  • Images: common web formats — JPG, PNG, GIF, WebP, SVG.
  • Audio: MP3, OGG, WAV, M4A, AAC, FLAC, WebM. Anything else is rejected with an “Unsupported audio type” message.

Upload fails with no clear reason

Section titled “Upload fails with no clear reason”
  • Sign out and back in. Uploads need a valid session; an expired one fails the upload even though the page still looks signed in.
  • Check your connection — large files on flaky Wi-Fi are the classic silent failure. Retry on a stable network.
  • Try a smaller test file. If a 100 KB image works, the original file’s size or format is the problem.

Playback problems

Section titled “Playback problems”
  • Audio won’t play: browsers differ in which codecs they ship — a file that plays in Chrome may not in Safari. MP3 is the safest format across every browser. Re-encode stubborn files to MP3 and re-upload.
  • Image won’t display: refresh the page first. If it’s broken everywhere, check the file still exists in your asset library and re-upload if needed.
