How can I convert pdf to png high quality on windows 10?

For command-line users, Poppler's pdftoppm is one of the cleanest batch options. It supports page ranges, DPI settings, and PNG output with the -png option. The default resolution is 150 DPI, but you can raise it with -r.

Example command to convert pdf to png free:

pdftoppm -png -r 300 input.pdf output

This creates files like:

output-1.png
output-2.png
output-3.png

This command-line PDF to PNG converts each PDF page into a separate PNG image. It is especially useful for users who are comfortable with Command Prompt or PowerShell and want a fast, scriptable solution without uploading files to an online converter.

Cons:

1. Not beginner-friendly

pdftoppm is a command-line tool, so users who prefer buttons and menus may find it confusing at first.

2. No visual preview

Unlike other PDF to PNG conversion tool, pdftoppm does not show a preview before conversion. You have to run the command first and then check the PNG output.

3. Large files at high DPI

If you use a high resolution like 300 or 600 DPI, the PNG files can become very large, especially for long PDFs or scanned documents.
