Discord's upload limits
As of 2026, Discord's documented limits are 20 MB per file on the free tier, 50 MB with Nitro Basic, and 500 MB on full Nitro. Because Discord can change or gradually roll out upload limits, check the limit shown for your own account before choosing a target size.
Compress once, share everywhere
Rather than paying for Nitro just to post a clip, set QuickCompress's target size to your server's actual limit and let it work out the encoding settings. Because compression runs locally with Apple Silicon hardware acceleration, you're not waiting on an upload to a browser tool first. Drop the file in, get the smaller one back, and post it.
