Why convert CHM to PNG?
CHM is Microsoft Compiled HTML Help, the format used for help files shipped with Windows software. The image shows a topic page from the help file, with its headings, paragraphs, lists and tables laid out as a document page.
PNG keeps every pixel exactly as rendered, so text, thin lines and flat colours stay crisp, and transparency is preserved.
Frequently Asked Questions
How do I convert CHM to PNG?
Drop your CHM file above and press Convert. Our servers unpack the compiled help archive, take a topic page from it and render it. The result is saved as a lossless PNG, ready to download.
What does the PNG from a CHM help file contain?
The help file is unpacked and a topic page from it is rendered, showing its headings, paragraphs, lists and tables.
Can a CHM file from older Windows software still be turned into PNG?
Yes. The compiled help archive is unpacked on our servers, so help files from any era of Windows software can be read and rendered.
What happens when a CHM file fills several PNG pages?
Each page is rendered at 144 dpi and saved as its own PNG image, named page-1, page-2 and so on, and they download together as one ZIP. A single page downloads as one PNG file.
Why is PNG a good fit for a CHM conversion?
PNG is lossless: the image keeps every rendered pixel with no compression artefacts, which keeps small text, table lines and drawings perfectly sharp.
Is my .chm file kept private?
Your file is uploaded over an encrypted connection, converted on our servers and deleted automatically within 24 hours. We never read, share or keep your files, and no account is needed.
