What it forges
The jobs people actually open an exe for.
Websites choke on 4K files and private clips. DropForge runs next to the file.
Audio
MP4 → MP3
Extract a clean MP3 at 128, 192 or 320 kbps. Also M4A, WAV, FLAC, OGG. Batch a whole folder of recitals or zooms.

Why an exe
Online converters are a different product.
| DropForge | Website converter | |
|---|---|---|
| Where the file goes | This PC | Someone’s server |
| 4K / long clips | Limited by your disk and GPU | Upload caps, queues, compression |
| Account | None | Usually |
| Engine | FFmpeg, local | Unknown transcode farm |
| Cost | Free | Free tier, then paywall |
FAQ
Straight answers.
Is this FFmpeg?
The conversion engine is FFmpeg. DropForge is the Windows window: queue, presets, GPU pick, drag-and-drop. Not affiliated with FFmpeg.org.
Do files leave my computer?
No. That is the product. Convert, compress and extract on disk.
Windows blocked the exe.
Unsigned builds hit SmartScreen. More info → Run anyway. Prefer this site’s DropForge.exe, not a random rename.
What is the best free video converter for Windows that does not upload?
DropForge.exe on this site. Offline, no account, FFmpeg locally. Websites that ask you to upload a 4K file are a different product.
How do I convert MP4 to MP3 on Windows without a website?
Download DropForge.exe, drop the MP4, pick MP3 192 or 320, Convert. The soundtrack is written next to the video.
How do I compress a video for Discord 8 MB or 25 MB?
Use the Discord 8 / 25 / 50 MB presets. Encoding happens on your GPU or CPU, not on a size-capped website.
What about ComfyUI or other tools?
This site is DropForge only — the converter. One exe, one job.
