Discord allows free users to upload files up to 25MB (previously 8MB). Most email providers limit attachments to 20MB or 25MB. However, even a short 1080p or 4K recording from OBS, GeForce Experience, or an iPhone easily exceeds 100MB to 500MB. Here is how to compress videos to exact file sizes on Windows without quality degradation.
Why Online Converters Are Risky and Inconvenient
Many users turn to free web-based video compressors. While they seem easy at first, they pose serious drawbacks:
- Privacy Risks: Uploading personal video clips, gaming footage with private voice chat, or confidential work recordings to third-party web servers exposes your data.
- Slow Upload Speeds: Uploading a 500MB video on standard home Wi-Fi can take 5 to 15 minutes before compression even starts.
- Hidden Limits & Watermarks: Most online tools insert ugly watermarks or throttle output resolution to 720p unless you buy monthly subscriptions.
The Smart Solution: Target Size Compression with fTool Media Converter
Rather than guessing bitrates in complex video editing suites like Premiere or HandBrake, fTool Media Converter includes intelligent Target File Size calculation. You specify the desired output size (e.g. 24.5 MB), and the software automatically calculates optimal 2-pass bitrate curves to fit precisely within the limit while maximizing visual clarity.
Drag & Drop Your Source Video
Launch fTool Media Converter and drop any MP4, MOV, MKV, AVI, or WebM file into the application window.
Select the "Target Size: 25 MB (Discord)" Preset
In the compression settings panel, choose the Discord 25MB preset (or enter any custom value, such as 10MB or 8MB). The app automatically adjusts video/audio bitrate allocation.
Export Locally in Seconds
Click Start Conversion. The video is compressed locally utilizing your PC's hardware acceleration in seconds with 0% data uploaded to the internet.
Tip: Safety Margin for Discord
When compressing for Discord's 25MB limit, fTool Media Converter defaults to 24.5MB to ensure safe transmission through Discord's API without hitting accidental file size rejections.
