pdf to png without quality loss

When a browser encodes a canvas to PNG, it always uses lossless compression — there's no lossy PNG encoding mode available through the standard browser APIs this tool uses. This means every PNG this tool exports is a pixel-for-pixel accurate capture of how the PDF page was rendered, with zero risk of compression artifacts, regardless of how detailed or text-heavy the page is.

This is different from JPG, where quality loss is a deliberate trade-off controlled by a slider — lower settings produce smaller files at the cost of visible artifacts, especially around sharp edges like text characters or thin diagram lines. With PNG, that trade-off simply doesn't exist: there's no slider because there's nothing to adjust, and no setting you could pick wrong that would introduce artifacts.

The only real cost of this guarantee is file size. Lossless compression can't shrink a detailed page as aggressively as lossy JPG compression can, so a PNG export of a busy, colorful page can end up considerably larger than a similar-looking JPG. For text documents and line-art diagrams, the size difference is usually much smaller, since those compress well even losslessly.

If you've had a bad experience with a JPG export looking blurry or artifact-heavy at a low quality setting, PNG export from this tool is the direct fix — there's no equivalent quality setting to get wrong, since the format itself guarantees the result matches the source render exactly.
