Convert .html file to image [closed]

Question

I am looking for any utility that will faithfully convert a .html file to an image format -- preferable png or jpeg. I have Googled for hours and downloaded a dozen or so free trials but nothing seems to do the job. Adobe Acrobat Pro almost worked but it is determined to shrink table cells to fit on a page rather than shrinking the whole table.

Any advice is appreciated.

Regards.

Answer 1

I am using wkhtmltoimage.

It is a fast command line tool which uses the webkit library to render any website. There are two versions one to generate pdfs and one to generate images.

wkhtmltoimage works with Windows, Linux and Mac.
