Free online TGA to AVI converter

A video editor or playback system that accepts AVI but not still-image TGA files requires the image to be rendered as video frames. Converting a TGA sequence also lets you set how long each image appears in the resulting video.

What the TGA format is

TGA (Truevision Targa) is a raster-image format used for rendered frames, game textures, and graphics that need an alpha channel. Graphics programs such as Adobe Photoshop and GIMP can open it; 3D software such as Blender can produce TGA renders. A TGA file is a still image, not a video.

What the AVI format is

AVI (Audio Video Interleave) is a Microsoft multimedia container that can hold video and audio streams. It is supported by many older editing and playback tools, but compatibility depends on the codec inside the file. AVI can contain compressed video or large uncompressed video; the extension alone does not determine quality or file size.

How to convert TGA to AVI

Online on 101convert.com

1. Upload the TGA image or images to the converter on this page. Multiple files can be converted in one batch; the page shows the per-file size limit.
2. Set show each picture for to choose how long each image appears.
3. Start the conversion, then download the AVI file.

Offline with desktop software

FFmpeg is a free, open-source command-line program for Windows, macOS, and Linux. For one still image, run:

ffmpeg -loop 1 -i image.tga -t 5 -r 30 -c:v mjpeg -q:v 2 output.avi

This creates a five-second AVI at 30 frames per second; change image.tga, the duration after -t, and the output filename as needed. For a numbered sequence such as frame_0001.tga, frame_0002.tga, run:

ffmpeg -framerate 30 -start_number 1 -i frame_%04d.tga -c:v mjpeg -q:v 2 output.avi

Change the frame rate or filename pattern to match the sequence. The frames should have matching dimensions and consecutive numbering.

Quality and compatibility

A still image must be assigned a duration to become video; a sequence’s frame rate determines its playback speed. Video encoding can discard TGA transparency, and the chosen AVI codec affects playback support and file size. The MJPEG commands above use lossy compression; keep the original TGA files if you need the uncompressed image data.
