Shrink AVI videos in seconds, right in your browser — no upload, no signup.
AVI Compressor shrinks the file size of .avi videos using modern video technology in place of AVI's older, less efficient encoding — so old, oversized files shrink much further, while the file stays an .avi that still opens in the same players. A quality slider lets you trade a bit of sharpness for a smaller file, so you decide how far to push it. Everything happens right here in your browser — your device does the work instead of a server, so your footage is never uploaded anywhere.
Drag and drop your .avi files, or click to browse. You can add several at once.
Use the slider or a quick preset, then click Compress. A progress bar shows you how it's going — everything happens on your device, so it can take a few minutes for a longer clip.
Save each file individually, or download every compressed file at once as a .zip.
Your videos are processed locally and never leave your device.
Works straight in your browser — no software, no account, no email.
