Convert Large Videos Without File Size Limits

Hit a paywall trying to convert a large video? Convertio stops at 100MB, EZGif at 200MB, Kapwing at 250MB on the free tier. These limits exist because their servers pay for every byte. AVMint processes files inside your browser, so the only limit is your device's RAM.

1

Open AVMint Compress or Convert

Visit the AVMint compress or convert tool. The page is small (<1MB) and loads ffmpeg-core on demand. No account, no plan selection.

2

Drop your large video

Drag in a file of any size — 500MB, 2GB, even larger. The file is mapped into ffmpeg.wasm's virtual filesystem in chunks, so you don't load the entire video into a single buffer.

3

Process and download

Pick your target size or format and click the action button. Processing takes longer for big files (it's running on your CPU, not a server farm), but it will finish — and you won't be asked to upgrade halfway through.

Tip

For very large files (>2GB), use a desktop browser rather than mobile. Desktop Chrome and Firefox give WebAssembly access to up to 4GB of memory per tab on 64-bit systems.

FAQ

Is there really no upper limit?

The practical limit is your available RAM. A 4GB video on an 8GB laptop will likely succeed; the same file on a 4GB Chromebook may not. There's no artificial cap imposed by AVMint.

Will my browser crash on a huge file?

If the file exceeds available memory, the tab may run out of memory. Close other tabs first, or pre-trim the video using AVMint's Trim tool (which uses copy mode and is nearly instant).
