How to Fix “Cannot resize GIF” Error in Discord?
A “Cannot resize GIF” error in Discord stops the upload process for GIF files that don’t meet the platform’s strict emoji rules. The error means Discord’s resizing and compression system can’t process the GIF to fit its limits for custom emoji.

The most common cause is a file size over 256 KB, with high resolution (above 128×128 px) and certain frame counts also stopping resizing. This happens even if the GIF looks small but has more frames or needs more compression than allowed.
1. Resize GIFs for Discord
Resizing GIFs is straightforward. There are plenty of third-party tools that can reduce the size of your media files, including GIFs. In this guide, we’ll use the EZGIF website to make your GIF meet Discord’s emoji requirements.
The site can optimize a GIF to reduce file size with minimal quality loss, which helps when you don’t want to lower the resolution right away. This is useful if you want to keep the original look of the GIF you’re sending.
However, optimization alone may not be enough, especially if your GIF is much larger than 256 KB. Normally, Discord lets users upload files up to 8 MB. But for a GIF emoji on a Discord server, the file must be 256 KB or less.
To resize your GIF for emojis and fix the error, follow these steps:
- First, open the EZGIF website on your browser by clicking here.
- There, click on the Choose File button and select your GIF.
Uploading GIF - Click Upload.
- Use the Compression level slider to adjust the amount of compression. This directly affects the GIF’s file size. If your GIF is quite large, choose a higher compression level.
Changing Compression Level - Finally, click the Optimize GIF option.
- Make sure the final size of the GIF is lower than 256 KB.
- After that, click the Save button.
Downloading Optimized GIF - Try uploading the saved GIF to Discord to see if the issue is resolved.
- If the error persists, use the Resize tool instead and set the GIF’s dimensions to 128×128.
- Once you do that, the error message should go away.
