The 20MB Upload Upgrade: Why Discord Just Doubled the Free Tier File Limit

The 20MB Upload Upgrade: Why Discord Just Doubled the Free Tier File Limit

Your screenshot folder just got a lot less annoying.

Discord has doubled its default file upload limit from 10MB to 20MB. You no longer need Nitro to send a larger photo, a longer clip or a chunkier PDF.

This article covers the Discord 20MB upload limit in full. That includes who benefits, what developers need to know about bots and webhooks, and a mobile catch that could trip people up.

🔥 Main Story: Discord's 20MB Upload Limit Replaces the Old 10MB Cap

Discord's developer changelog confirms the change in its September 3, 2026 entry. The default file upload limit rose from 10 MiB to 20 MiB for users, bots, webhooks and interaction responses.

Consumer coverage described the same change in plain terms. PCGamesN reported that non Nitro users can send photos, videos, PDFs, music files and other attachments up to 20MB.

The key fact: the limit doubled for everyone on the default tier, and the change reaches past people into bots and webhooks.

🎮 What Happened

The developer side landed first in Discord's docs. The entry is short and technical, and it points readers to the documentation on file uploads.

Wider coverage followed through the month. A TechJournal explainer from September 29 says the API documentation lists a 20 MiB default, with higher limits possible through Nitro or server Boosts.

📤 Upload flow: 📁 You pick a file → 📏 Discord checks the original size → ✅ Under 20MB, it sends → ⛔ Over 20MB, it fails → 🗜️ Shrink it and try again

🧠 Why It Matters

File size has been a quiet pain point for years. A short gameplay clip, a high resolution screenshot or a scanned document could all blow past the old cap.

Doubling the limit fixes many of those cases without a subscription. For communities, it means fewer links to outside hosting sites and fewer files squeezed until they look bad.

⚠️ Important: Discord's docs say MiB, while consumer pages say MB. The numbers are close, but not identical, so read the exact unit if you build around the limit.

⚡ Key Details

🔍 Deeper Breakdown

What Changed for Developers

Developers get the most interesting part of the update. The changelog lists bots, webhooks and interaction responses alongside regular users, so an app can attach larger files to its own messages.

That matters for bots that post images, exports or logs. It also matters for slash command replies that return files.

One caution comes from history. An earlier GitHub issue shows a previous limit increase that worked for users, bots and interaction webhooks, but initially failed for regular webhooks with a 413 error. Test your own webhooks rather than assume.

The Mobile Catch

Reports describe a change on phones. The mobile app used to compress a file first and then check whether the result fit under the cap.

Now the original file size is what counts. Discord's own support page, as relayed by Rozetked, says the company will keep experimenting with free attachment size, so the number could change.

In practice, a large phone video that once squeaked through after compression could now be rejected. The fix is to shrink or re export it before sending.

MiB Versus MB

The changelog says 20 MiB. A MiB is 1,048,576 bytes, so 20 MiB is 20,971,520 bytes.

Consumer pages round that to 20MB. For most uploads the difference is invisible, but a file sitting right at the edge could behave differently than you expect.

💡 Note: If an upload fails, check the original file size first, especially on a phone, before trying again.

What We Know

• Confirmed: the default limit is now 20 MiB, and it covers users, bots, webhooks and interaction responses.
• Reported: free users can send up to 20MB, Nitro tiers still go higher, and mobile now checks original size.
• Not confirmed: how Boost tier limits compare after the change, and whether Discord will adjust the free limit again.

What Could Happen Next

This section is speculation. Discord's support page reportedly says it is still experimenting, so the limit could move up or down.

Nitro tiers could also be adjusted to keep their gap over the free tier. None of that has been announced.

📊 Quick Comparison

💡 Creator Note

For server owners, bot developers and creators, the bigger limit is useful but worth testing. Here are a few ways to use it.

• Post higher quality screenshots and short clips in your server.
• Let your bot attach larger exports, such as logs or reports.
• Test your webhooks with a file between 10 and 20 MiB.
• Tell members to shrink large phone videos before uploading.

🚨 What Happens Next

• Watch Discord's support pages for updates to the free limit.
• Watch for Boost tier numbers to be clarified.
• Watch your bot logs for upload errors after you raise file sizes.
• Watch the October changelog for any follow up.

Limit rises → Users upload more → Mobile edge cases appear → Discord adjusts

Final Takeaway

This is a small number with a big effect. Doubling the default limit removes a daily annoyance for free users, and it quietly makes bots and webhooks more capable too.

The details matter, though. The unit is MiB, the mobile check now looks at the original file, and Discord has said it is still experimenting.

The best upgrade is the one you notice only when a file that used to fail finally goes through.
