You can avoid some ingestion and transcoding problems of your creative media by following these tips for their file names:
Avoid using these special characters:
/\?#[]{}<>@!$&'"()*+,;=%, and space.If you must include these special characters, make sure they are properly URL-encoded so that they can be inserted in a URL. For example, a space should be percent-encoded as
%20. For specifications on encoding, see RFC 3986 URI Generic Syntax.Keep file names short. This ensures that the URLs that refer to them won’t be too long.
Before production you can catch unexpected parsing failures or validation errors by testing your URLs and companion creative trackers with these validators: W3C Link Checker, URL Validator - utils.com.
For example, this file name could cause a malformed request to Triton ad servers:
Blork Forever Footwear [Autumn 2026].mp3
You can rename the file by replacing the spaces with underscores and removing the square brackets. This also makes the file name shorter:
Blork_Forever_Footwear_Autumn_2026.mp3
