The best animation format for transparent backgrounds on mobile. Export as MOV, WebM, or HEVC with full alpha channel — optimized for MP4 conversion, overlay, and compositing.
Full Platform Support
Three formats ensure transparent video works on every device, browser, and professional editing tool.
WebM (VP9)
VP9 codec with alpha channel support
HEVC (H.265)

Frequently Asked Questions
What is the best animation format for transparent background on mobile apps?
For cross-platform mobile apps, use WebM (VP9) for Android/Chrome and HEVC with alpha channel for iOS/Safari. Masko exports both formats automatically so your transparent background animations work on every device.
How do I convert MP4 to transparent animation for mobile apps?
Standard MP4 (H.264) does not support transparency. You need to use formats with alpha channel support: WebM (VP9), HEVC (H.265), or MOV with HEVC alpha. Masko generates animations with transparent backgrounds natively — no conversion needed.
Can I export transparent background MOV files for overlay use?
Yes. Masko exports MOV files with HEVC alpha channel, which is the standard format for transparent video overlays in Final Cut Pro, After Effects, DaVinci Resolve, and OBS Studio.
What is alpha channel video and why does it matter?
Alpha channel is a fourth channel (alongside red, green, blue) that stores transparency data for each pixel. It allows your animation to overlay on any background without a colored box. Masko exports all animations with full alpha channel support.
How do I optimize transparent animations for mobile app performance?
Use WebM for Android (smaller file size, hardware-decoded on modern devices) and HEVC for iOS (native hardware acceleration). Keep animations under 5 seconds and use the HTML5 video element with the source tag pattern for cross-browser support.
