Merge HTML Files and Export to Images in Python

Combine HTML documents and render the resulting slides as PNG images with a cross-platform Python API

Merge HTML Files and Export to Images Using Aspose.Slides

Aspose.Slides for Python via .NET lets you import multiple HTML documents into one Presentation and render the resulting slides as images. Use SlideCollection.add_from_html to import each HTML stream, then call Slide.get_image and save each resulting IImage with ImageFormat.PNG.

Merge HTML Files to PNG Images in Python

Create a Presentation, import the source HTML files in order, and render each generated Slide as a separate PNG image.

Python code for merging HTML files and exporting the slides as PNG imageshtml_file_paths = ["first.html", "second.html"]

with slides.Presentation() as presentation:
    presentation.slides.remove_at(0)

    for file_path in html_file_paths:
        with open(file_path, "rb") as html_stream:
            presentation.slides.add_from_html(html_stream)

    for slide in presentation.slides:
        file_path = f"merged_slide_{slide.slide_number}.png"
        with slide.get_image(1, 1) as slide_image:
            slide_image.save(file_path, slides.ImageFormat.PNG)
