Why convert CHM to HEIC?
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.
HEIC uses High Efficiency Image Coding, the format iPhones and iPads save photos in, so the image is compact while staying sharp.
Frequently Asked Questions
How do I convert CHM to HEIC?
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 HEIC image, ready to download.
What does the HEIC 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 HEIC?
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 HEIC pages?
Each page is rendered at 144 dpi and saved as its own HEIC image, named page-1, page-2 and so on, and they download together as one ZIP. A single page downloads as one HEIC file.
How compact is the HEIC made from a CHM file?
HEIC uses High Efficiency Image Coding, which typically needs about half the space of a JPG of similar quality, so even detailed pages stay small.
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.
