About converting JWC to PNG
JWC is the drawing format of the DOS-era Jw_cad (JW_CAD), the predecessor of the Windows Jw_cad still popular in Japan. Many Japanese architectural drawings from the 1990s survive only as .jwc files, and virtually no current CAD software opens them. zumen-gate reads JWC in beta (lines, circles, arcs, ellipses, text, points).
PNG lets you drop the drawing into slides, reports, chat, or email as a regular image.
All conversions run through a single engine with a common intermediate representation. Every conversion produces a loss report tallying which entities were converted as-is and which were approximated or dropped — so you can trust the output, or know exactly why not.
FAQ
JWC → PNG conversion — frequently asked questions
Will my drawing break when converting JWC to PNG?
The conversion is a deterministic, structural translation through a common intermediate representation. After every conversion you get a loss report listing exactly which entities were converted, approximated, or dropped — so you can verify the result on the spot.
Is there a limit on conversions or downloads?
No. Conversions and downloads are unlimited, and no account is required. The only limit is 10MB per file.
What happens to the files I upload?
Transfers and storage are encrypted, and your drawings are never sold or shared with third parties. On the free tier, uploads are used to improve the service and train our AI models, so please avoid uploading confidential drawings.
