Key Takeaways
- 1.Email is the most restrictive. Most providers cap at 20-25MB. If you need to email a video, you almost certainly need to compress it first.
- 2.Discord Free (10MB) is a common pain point. Most users hit this limit regularly. Our Discord video compressor and Discord audio compressor are built specifically for this.
- 3.Telegram and WhatsApp are the most generous messaging apps at 2GB each. Signal is relatively restrictive at 100MB.
- 4.Social media platforms vary wildly. YouTube allows 256GB while X (Twitter) images are capped at 5MB. Always check the specific platform before uploading.
- 5.Compressing before uploading saves time and data. Even when a platform allows large files, a compressed video uploads faster and uses less bandwidth for viewers.
Frequently Asked Questions
Which email provider has the largest attachment limit?
Most major email providers allow 25MB attachments (Gmail, Yahoo, iCloud Mail, ProtonMail). For larger files, use cloud storage links or compress your files with our free video compressor or image compressor.
What is Discord's file upload limit?
Discord Free allows 10MB uploads. Discord Nitro Basic raises this to 50MB, and Discord Nitro allows up to 500MB per file. Use our Discord video compressor to fit files under the free limit.
How can I send files that exceed the platform limit?
You have two options: compress the file to fit within the limit using our free video compressor, audio compressor, or image compressor, or use a file sharing service like Google Drive or WeTransfer and share a link.
What is the largest file I can send on WhatsApp?
WhatsApp allows document files up to 2GB. However, media sent through the camera or gallery may be automatically compressed by WhatsApp. For the best quality, compress manually with our WhatsApp video compressor before sending.
Do these limits apply to all file types?
Most platforms apply the same size limit regardless of file type. However, some platforms restrict certain formats -- email providers may block executable files, and social media platforms typically only accept specific image and video formats.
How often do platform limits change?
Platform file size limits change occasionally, usually increasing over time. We update this page regularly to reflect the latest limits. Discord, WhatsApp, and Telegram have all increased their limits in recent years.
