About the S3M format
S3M is ScreamTracker 3's module format — the 1994 standard that carried PC demo music past the AdLib's FM chip into sampled instruments, with PCM samples, FM instruments or both in one file. Half the classic DOS game soundtracks you remember were S3Ms.
Conversion renders the module through the tracker engine to MP3 or WAV — the FM-vs-sample mix is resolved exactly the way the composer intended, frozen into a universally playable waveform.
+ Strengths
- ✓FM + PCM hybrid instruments
- ✓Iconic DOS-era game soundtracks
- ✓Well-specified, stable format
! Limitations
- −Pattern limits of 1994
- −FM playback differs across engines
- −Adlib-specific quirks may differ
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

Is this S3M 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 S3M to PNG24?
No — PNG24 is a lossless format, so every pixel of the converted image matches your original S3M file. You can also adjust the quality/size balance before converting when the target format supports compression.
Are tags like title and artist preserved?
Tag handling varies between target formats and this conversion focuses on the audio itself. For archival copies where tags matter, keep the original file; the converted copy is for playback and sharing.
Can I convert a whole folder of S3M files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
