FAQ  MediaWiki to JPEG Converter

Why is the image sometimes very wide or very tall?

The canvas size is calculated from the content of each cell, so many columns or long text can create a wide image. Try reducing font size, padding, or the number of columns to keep dimensions manageable.

Can I change the font family used in the image?

The converter currently uses a standard Arial, sans-serif stack for compatibility. You can post-process the image in an editor if you need a different typeface, or adapt the code if you are integrating this logic into your own project.

Why does copy to clipboard sometimes fail?

Image clipboard access depends on browser support and permissions. If copying fails, your browser may not support writing images to the clipboard from the web page. In that case, use the Download button and paste the saved file manually.

Is JPEG the only supported format?

This tool focuses on JPEG output for good compatibility with presentations, documents, and social media. If you need PNG or WebP, you can convert the downloaded JPEG using another image tool, or adapt the canvas export code in your own implementation.

Will the output be retina/high-DPI aware?

The generated image uses the canvas size in CSS pixels. On high-DPI displays it will still look sharp in most presentation and document workflows, but if you need extra resolution you can scale up font size and padding to generate a larger image.
