If you've ever needed to upload a large image or game file, commonly used by organizers to collect match result proof from participants, you would have been out of luck. The default 250KB size limit restricts you to small images, or forces you to find another host for your files.
Now, for tournaments hosted by Challonge Premier subscribers, the file attachment size limit has been increased to 25MB! Think of it this way: if you can attach your file to an email, then you can upload it to Challonge!
Large file attachments are just one of many Challonge Premier features. Upgrade Now!
