This guide takes a QuickTime .mov clip that Discord refuses to send and gets it under the upload cap, in your browser — nothing is uploaded to a conversion service. You need the file and a modern browser.
Start from the right diagnosis: MOV is not why your upload was rejected. Discord's File Attachments FAQ lists the file types people send most often, and MOV is on that list by name, alongside JPEG, PDF, MP3 and MP4. Size is the cause you can act on, and it is what this guide addresses — though it is not the only refusal Discord documents. The same FAQ describes NSFW content scanning: "If these settings are enabled and the system detects the image could be NSFW, it will block the upload." That clause is scoped to images and to those settings being on, but a blocked upload is not automatically a size verdict.
Before you start: know which ceiling applies to you
There is no single Discord upload limit, which is where most of the confusion starts. Three things decide your ceiling.
Your account tier. Discord's File Attachments FAQ states it directly: "For non-Nitro subscribers, the maximum file upload is 20MB." The same page adds, "If you need more room regularly, Nitro Basic offers 50MB and Nitro offers up to 500MB."
| Tier | Per-file upload limit |
|---|---|
| Free (non-Nitro) | 20MB |
| Nitro Basic | 50MB |
| Nitro | up to 500MB |
| Nitro Classic (not available for purchase) | 50MB |
Nitro Classic appears only because legacy subscribers still have it: "At this moment, you can only subscribe to Nitro and Nitro Basic. Nitro Classic is not available for purchase."
The server you are posting in. Server Boosts raise the ceiling for everyone in that server at two levels: "50MB Upload Limit for all members (server only)" at Level 2, and "100MB Upload Limit for all members (server only)" at Level 3. Server only means it does nothing in a DM or a group chat. Level 1 does not raise the upload limit at all; Discord's caps table marks it as "Same" as the base tier. Discord also says it is running an experiment that lets some servers "upgrade the file limit to 250MB by purchasing Larger File Uploads (5 Boosts)" — some servers, not a feature you can count on.
How the two combine. Discord's developer reference gives the only official statement on this: "The default limit is 20 MiB for all users, but may be higher for users depending on their Nitro status or by the server's Boost Tier. The attachment_size_limit value provided when working with interactions is calculated as the maximum of these values." Maximum, not sum: a Nitro user in a Level 2 server gets 500MB, and a free user in a Level 3 server gets 100MB.
Two more notes from that page. The limit "applies to each file in a request" — per file, not per message. And the developer docs say 20 MiB where the help center says 20MB; Discord publishes no conversion between the two, so do not try to squeeze into the gap.
One caveat: Discord states at the top of the FAQ that it is "currently experimenting with various file upload size limits" and that "Select users may have the ability to upload larger file sizes." Discord does not say who those users are or when the experiment ends, so check the official documentation for the limit on your own account.
Step 1: Check the file size on disk
Right-click the .mov and read its size in Finder or Explorer. That number — not some post-processing number — is the one Discord compares against your ceiling.
On whether size is checked before or after compression, Discord is explicit: "We've now moved mobile to the same pre-compression check that desktop has always used, so the number you see is the number that counts."
The consequence is stated in the same FAQ: "because we now check file size before compression rather than after, the real-world effect varies by platform. Desktop and iOS users should generally find uploads easier than before. On Android, where source files tend to be larger, you may hit the size limit more often than you did previously, even though the stated number is higher."
So the free limit rose from 10MB to 20MB in August 2026, and some Android users started getting refused more often — not because Android has a lower cap, but because the original file is now what gets measured. The working instruction: make the source file itself smaller before you upload it.
Step 2: Ignore the 10MB you may have found
If you searched this and got 10MB, you were not imagining it. Discord's own Account Caps article still lists "File Sharing Limit 10MB 50MB 500MB", and a Nitro FAQ heading still reads "Q: Why do I need Nitro to upload more than 10MB of files?" The File Attachments FAQ is the more recently updated page and says, verbatim, "As of August 2026, the free upload limit is 20MB (up from 10MB)". Go with 20MB, and check the official documentation before relying on any number here months from now.
Step 3: Convert the MOV to MP4 and re-encode it smaller
Converting the container to MP4 is worth doing on its own merits: Discord's developer docs recommend that apps filtering for video "include .jpg for image uploads and both .mp4 and .mov for video uploads, as some mobile clients rely on those extensions" — an officially acknowledged client difference. Discord's accepted-types list qualifies MP4 by codec — "MP4 (Video encoded with H264, HEVC/H265, or AV1)" — and lists MOV with no codec note at all, so MP4 is simply the better-documented target.
Try it right here
Runs in your browser. Your file is not uploaded anywhere.
This runs inside your browser tab: the file is read from disk, re-encoded locally, and handed back — it never leaves your device. The MOV to MP4 converter is the same tool on its own page.
If the result is still above your ceiling, the bitrate is what to attack: run it through video compression and check the size on disk again before retrying.
Common mistakes
- Renaming
.movto.mp4. This changes zero bytes: whatever the file weighed before the rename, it weighs after. Discord's docs also note that extension filtering in File Upload components and Slash Command Options "only checks the file extension against the filename and does not inspect the file contents" — a name check, not a contents check. - Buying one Boost and expecting more room. Level 1 (2 Boosts) leaves the upload limit where it was; Level 2 (7 Boosts) is the first level that moves it. See Discord server boost upload limit for the full ladder.
- Adding your tier to the server's tier. The official word is "maximum of these values." Nitro plus a Level 2 server is still 500MB.
- Assuming a Boost limit travels with you. "(server only)" is Discord's own parenthesis. The 100MB you get in a Level 3 server does nothing in a DM.
- Expecting Discord to compress it for you on mobile. Discord does document mobile-only upload settings — a "Video Uploads" section where "By selecting the 'Data Saver' option, your videos will upload more quickly and consume less data" — but it does not publish what those settings compress to, and the size check happens before compression regardless.
FAQ
Does Discord support MOV files?
Yes. Discord's File Attachments FAQ lists MOV among "the most common examples" of uploadable file types, and the developer docs put .mov in the video file group alongside .mp4, .qt and .webm. Note that Discord presents its list as common examples rather than a complete whitelist.
What is the file size limit for a MOV on Discord? The same as for any other file: 20MB on a free account, 50MB on Nitro Basic, up to 500MB on Nitro, with a Level 2 or Level 3 server raising it to 50MB or 100MB inside that server. The limit applies per file, not per message.
Can I just rename my .mov file to .mp4 to get around the size limit? No. Renaming does not change the file's size, and size is what gets measured. A genuine MP4 needs the container rewritten — which is what the converter above does.
Why did my MOV upload fine on my laptop but fail from my Android phone? Discord attributes this to the pre-compression check: "On Android, where source files tend to be larger, you may hit the size limit more often than you did previously, even though the stated number is higher." The cap is the same; the file being measured is bigger.
Is there a length limit for videos on Discord? Discord's official documentation does not state one. The published limits are on file size, per file.
Will boosting a server let me post my big MOV in DMs too? No. Both Boost perks are worded "(server only)". For DMs and group chats you are back on your account tier — see why Discord says your file is too large for what to do in that case.
Limits cited from Discord's File Attachments FAQ, Nitro FAQ, Server Boosting FAQ and developer API reference, checked 16 September 2026. Discord has changed the free limit before and is still experimenting — verify against the official documentation before relying on a number.
