Free online TGA to WEBM converter

A TGA still image needs to become a timed video when a website, editor, or playback device accepts WEBM but not TGA. Converting a single image creates a video that holds that picture; converting a numbered image sequence can produce moving footage.

What the TGA format is

TGA (Truevision Targa) is a raster image format used for textures, rendered images, and graphics that may include transparency. Programs such as Blender, GIMP, and Adobe Photoshop can create or export TGA files. A TGA file is normally a still image, so it has no built-in frame rate or playback duration.

What the WEBM format is

WEBM is a media container commonly used for web video. It can contain video encoded with VP8, VP9, or AV1, and audio encoded with Opus or Vorbis. It is useful for browser playback and compact sharing; converting a still TGA requires choosing how long the image appears, while an image sequence also requires a frame rate.

How to convert TGA to WEBM

Online on 101convert.com

1. Open the TGA-to-WEBM converter on 101convert.com and upload one or more TGA files. The page shows the per-file size limit.
2. Set show each picture for to choose how long each picture appears.
3. Start the conversion and download the converted WEBM file or files.

Offline with FFmpeg

FFmpeg is free, open-source software available for Windows, macOS, and Linux. For one still image, set the desired duration in seconds in -t:

ffmpeg -loop 1 -framerate 30 -i input.tga -t 5 -c:v libvpx-vp9 -pix_fmt yuv420p -an output.webm

This example holds input.tga for five seconds and encodes a 30 fps video. For a numbered sequence such as frame0000.tga, frame0001.tga, and so on, use:

ffmpeg -framerate 24 -i frame%04d.tga -c:v libvpx-vp9 -pix_fmt yuv420p -an output.webm

Change 24 to the intended frame rate. Keep the sequence numbering consistent and start at 0000, or add FFmpeg's -start_number option to match the first file.

Quality and compatibility

The example commands use yuv420p, a widely compatible pixel format that discards TGA transparency. VP9 can carry alpha, but playback support varies; use an alpha-capable encoding workflow only when the target player supports it. With yuv420p, image width and height should be even; pad odd dimensions or adjust them before encoding. A still-image conversion cannot create motion that is not present in the source.
