Send Large MP4 Video Files Without Quality Loss
MP4 is the universal standard for video, but modern 1080p and 4K recordings quickly reach 500 MB to 3 GB — far beyond Gmail and Outlook's 25 MB attachment ceiling. LimeShare lets you transfer full-resolution MP4s with client-side zero-knowledge encryption.
Up to 500 files or folders · Client-side AES-256-GCM encryption · Zero accounts required

Why standard email fails for MP4 Video
Email gateways enforce a strict 20–25 MB total MIME message limit. Base64 encoding inflates binary files by 33 %, meaning an MP4 file larger than 18 MB will immediately bounce with an 'attachment size exceeded' error.
Best practices for sending MP4 Video
- Keep H.264/H.265 video and audio streams uncompressed inside the MP4 container for perfect playback.
- Use 'Burn after first download' if sharing confidential draft edits or unreleased footage.
- Add an Argon2id password to prevent unauthorized viewing even if the link is forwarded.
Frequently asked questions
Will LimeShare compress or re-encode my MP4 file?
No. Unlike YouTube, WhatsApp, or Google Drive, LimeShare never touches or re-encodes your video. Your MP4 is encrypted client-side and delivered byte-for-byte in original bitstream quality.
Can the recipient play the MP4 directly in their browser?
Yes. LimeShare includes an in-memory zero-knowledge media preview player. Recipients can stream and preview MP4s under 256 MB directly in RAM before saving.
How fast is the MP4 upload and download?
Uploads stream in parallel 8–64 MB chunks directly to high-speed encrypted edge storage with zero egress limits, saturating your full broadband connection.
