AVI to GIF Converter

What happens when you convert AVI to GIF

• Sound is dropped, because GIF cannot carry audio.
• Frames are sampled at 12 per second and scaled to 480 pixels wide by default, then mapped to a 256-colour palette built from the clip itself.
• Keep clips short: a GIF of more than about 10 seconds is usually several megabytes.

How to convert AVI to GIF online

1. Press "Choose AVI files" and select one or more files, or drag them onto the box. You can add files of any size your device can hold in memory.
2. Adjust the settings if you need to: resolution and quality control the size of the result. The defaults suit most people.
3. Press "Convert to GIF". The first audio or video conversion downloads the converter engine, about 32 MB, which your browser then keeps for next time.
4. Save each GIF with its download button. Close the tab and every trace of the files is gone from memory.

Why convert AVI to GIF?

AVI files usually come from older camcorders, digital cameras and legacy video libraries. People convert them to GIF because a GIF loops silently in any chat app, email or forum post without a play button.

In short, AVI is good at what it was made for, and GIF is the more practical choice when the file has to open, upload or print somewhere else. AVI does not play in browsers; plays in VLC and Windows players, while GIF opens and animates in every browser.

How to convert AVI to GIF on Windows, Mac, iPhone and Android

On Windows

Open this page in Chrome, Edge or Firefox, drag your AVI files in from File Explorer, and press Convert. Each GIF is saved to your Downloads folder. If you prefer a desktop program, VLC can also convert AVI to GIF: choose Media, then Convert / Save.

On a Mac

Safari, Chrome and Firefox all work. Drag the AVI files from Finder onto the drop zone and the GIF files land in Downloads.

On iPhone and iPad

Open the page in Safari and tap Choose AVI files. You can pick from Photos or from the Files app. The converted GIF appears in Files, in the Downloads folder; to put it in your photo library, open it there, tap Share and choose Save Image.

On Android

Open the page in Chrome, tap Choose AVI files and pick them from Files or your gallery. The GIF is saved to the Download folder, where any file manager can find it. Keep the screen on while a long video converts, because Android may pause a tab in the background.

Best settings for AVI to GIF

Width and frame rate decide the size of a GIF far more than anything else. 480 pixels at 12 frames per second is a good balance for reaction clips; 320 pixels suits chat apps with small previews; 640 pixels at 15 frames per second looks smooth but grows quickly.

Every extra second adds frames, so trim the source to the moment you need before converting. A 3 second clip at the default settings is usually well under 2 MB.

AVI vs GIF: the differences

About AVI and GIF files

What is an AVI file?

AVI dates from Windows 3.1 and predates the codecs most people use today. It is still readable by almost every desktop editor, which is why some older software asks for it.

What is a GIF file?

GIF stores each frame with a palette of at most 256 colours, so photos turn grainy and animations get large fast. Transparency is on or off per pixel, with no soft edges.

AVI to GIF not working? Common problems

• The conversion is slow. Audio and container changes take seconds, but re-encoding video runs on your own processor. Lower the resolution to 720p, close other tabs, and keep the device plugged in.
• The tab stops or reloads on a very large file. Browsers limit how much memory one tab can use, around 2 GB and less on phones. Split long recordings or convert them on a computer.
• The GIF will not play on an old device. Try the other formats offered for AVI, or choose 720p, which older players handle more reliably.

Convert AVI to GIF with ffmpeg

This converter runs ffmpeg inside your browser. If you would rather use the ffmpeg command line on your own computer, this command produces an equivalent GIF with the same kind of settings:

ffmpeg -i input.avi -vf "fps=12,scale=480:-2:flags=lanczos,split[a][b];[a]palettegen[p];[b][p]paletteuse" -loop 0 output.gif

Replace input.avi with the name of your file. For a whole folder of AVI files, run the command in a loop, or drop them all on the converter above, which processes them one after another.
