How to use the svga maker
- Sign in with Google, or with your VoltKit account. Your remaining conversions for today and this month appear above the form.
- Choose an MP4, MOV, WebM or GIF within the size shown. Short clips on a plain background key out most cleanly.
- Choose the frame rate, output width and the background colour to remove, or keep the clip's own transparency. Then create your SVGA.
- Download the finished file from Your generations. Conversions keep going on the server if you close the page, and stay in your history.

- Background keying: detect automatically, black, white, green or blue, or keep the source's transparency
- Exports SVGA 2.0 files whose frames keep a full alpha channel
- Conversion history and downloads whenever you come back
SVGA animations in mobile and live apps
An SVGA file holds the frames of an animation as images, with their timing, and an SVGA player library plays it on top of whatever is on screen. Live-streaming and social apps use it for virtual gifts, VIP badges, entrance effects and stickers.
Every frame keeps a full alpha channel, so glows and soft edges sit cleanly over video and interface, which a GIF, with its on-or-off transparency, cannot do. Open-source players exist for Android (SVGAPlayer-Android), iOS (SVGAPlayer-iOS), Flutter (svgaplayer_flutter) and the web (SVGAPlayer-Web).
- Transparency: a GIF is on or off per pixel; an SVGA keeps full alpha, for soft edges and glows.
- Plays in: a GIF plays in anything that shows images; an SVGA plays in Apps with an SVGA player.
What happens to your clip
The conversion runs on VoltKit's SVGA service. These are its stages, in order.
- Frames: the clip is decoded at the frame rate you chose and scaled to your width.
- Background keyed: the colour you picked, or the one detected, becomes transparent.
- Trimmed: each frame is cropped to its content, and identical frames are stored once.
- Packed: the frames go into palette images inside one SVGA 2.0 file.
Settings and output
Pick the background your clip was made on: that colour is the one that becomes transparent.
- Input: MP4, MOV, WebM or GIF
- Maximum size: 20 MB by default per file
- Frame rate: 12, 15, 20, 24 or 30 fps
- Output width: 240, 300, 400, 500 or 640 px
- Background: detect automatically, black, white, green or blue, or keep the source's transparency
- Output: an .svga file (SVGA 2.0) whose frames keep a full alpha channel
Free, with daily and monthly limits
SVGA Maker is free for every signed-in account. By default each account can start 20 conversions a day and 100 a month, with files up to 20 MB; the form shows your current limits and what is left. A conversion that fails does not count against your limits.
Unlike most VoltKit tools, SVGA Maker does not run in your browser: the clip is uploaded to VoltKit's conversion service, and only your account can see its history and download its files. The upload is deleted about 48 hours after it was last used. Avoid uploading private or sensitive footage.
