AVI to PNG24 Converter
Processing entirely on your device — large files may take a moment.
AVI Video and PNG (24-bit Truecolor) exist for different jobs: AVI is Microsoft’s classic video container from the 90s. Files are large by modern standards but old devices and software still produce them. Convert PNG24 images like any PNG — to JPG for photos, WebP for the web.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
How AVI compares to PNG24
| AVI | PNG24 | |
|---|---|---|
| Compression | Legacy codecs (DivX/Xvid era) | Lossless (DEFLATE) |
| Best for | Reading old archives | Screenshots, logos, sharp graphics |

About the AVI format
AVI (Microsoft, 1992) is one of the oldest video containers still encountered. It has no native understanding of modern features — variable frame rates, modern codecs, subtitles, chapters — and stores everything through a 32-bit indexing system that caps reliable file sizes around 2 GB (OpenDML extensions patched some of this). Most AVIs you meet today are DivX/Xvid-era rips or old capture-card output.
There is no reason to produce AVI today; the realistic task is converting old libraries into MP4, which typically cuts file size by half or more at equal or better quality.
+ Strengths
- ✓Opens in legacy Windows tooling
- ✓Simple structure, decades of player support
! Limitations
- −Obsolete: no modern codecs or features by design
- −Large overhead, ~2 GB practical ceiling
- −Codec zoo inside — playback is guesswork
About the PNG24 format
PNG was created in 1996 as a free, open replacement for the patent-encumbered GIF, and it has been the reference lossless image format ever since. Pixels are compressed with the DEFLATE algorithm (the same one inside ZIP files), which reproduces the original image exactly — bit-for-bit — while supporting full 8-bit or 16-bit alpha transparency. Screenshots, logos, icons, charts and anything with text or sharp edges should live in PNG.
Because it never discards information, PNG files of photographs are several times larger than JPG — that is the price of perfection. Modern PNG encoders add filters per scanline that make screenshots and flat-color graphics compress surprisingly well. PNG also became the base of APNG, the animation extension that browsers play natively.
+ Strengths
- ✓Truly lossless — every pixel survives exactly as it was
- ✓Full alpha transparency with smooth edges, not 1-bit masks
- ✓Open standard, unpatented, with excellent tooling everywhere
- ✓Ideal for text, line art and flat-color graphics — sharp edges stay sharp
! Limitations
- −Photographs become several times larger than JPG
- −Base format has no animation (that is the APNG extension)
- −16-bit or high-resolution PNGs can grow very heavy
Why convert AVI to PNG24?
Converting makes sense where the strengths of PNG24 meet what AVI cannot give you. Truly lossless — every pixel survives exactly as it was Meanwhile Obsolete: no modern codecs or features by design One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this AVI to PNG24 converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting AVI to PNG24?
No — PNG24 is a lossless format, so every pixel of the converted image matches your original AVI file. You can also adjust the quality/size balance before converting when the target format supports compression.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
Does converting AVI to PNG24 re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
