Are my files uploaded to a server?

No. This conversion runs inside your browser using your own device’s processing power, and the file is not uploaded. Once a tool has been used once (video, text recognition and background removal download their engine from this site the first time), it keeps working when your connection drops.

Why are my PNG files so large?

PNG stores every pixel exactly, with no lossy compression. For photographic pages that gets big quickly — convert to JPG instead if size matters more than perfect fidelity.

Do PNGs keep transparency?

PDF pages are rendered on a white background, so the exported images are opaque.

Every page becomes a PNG image — lossless, so text edges and thin lines stay perfectly crisp with none of the fuzziness JPG introduces around high-contrast detail.

PNG is the right choice when the page is text, a diagram, a chart or a screenshot. If the page is mainly photographic, JPG produces a much smaller file — compare both if fine detail matters.

Supported formats and limits

Input: PDF (any version)
Output: One PNG per page
Why PNG over JPG: Sharper text and line art, no compression artefacts
Transparency: None — pages are drawn on white, as a PDF reader shows them
Where it runs: In your browser; nothing uploaded

Not for: Small file sizes — PNG is lossless and much larger than JPG for the same page; choose PDF to JPG if size matters.

What PNG keeps, and what it does not

PNG stores every pixel exactly as it was drawn. The edges of letters, thin table rules and the flat colours of a chart come out without the blur that JPG compression adds, and the image does not change if it is saved again later. For that reason there is no quality setting: the slider disappears when PNG is chosen.

The images are not transparent. Each page is first filled with white and then drawn on top, the way a PDF reader shows it, so any area the PDF leaves empty comes out white.

How large the files get

The size of a PNG depends on how much detail the page holds. A page of black text on white compresses well. A page with photographs, or a scanned page, which is itself a photograph, makes a PNG much larger than the same page saved as JPG. Size also grows with resolution: each step in the Resolution menu enlarges both sides of the image, so Print (216 dots per inch) holds more than twice the pixels of High (144).

For scanned documents, choose JPG instead; the format buttons sit at the top of the same tool. If finished PNGs are too large to send, /compress-image can reduce the number of colours in each one while keeping them as PNG, which works well for pages of text and diagrams.

When PNG is the better choice

Choose PNG when the page will be worked on afterwards: pasting a table or chart into a slide, cropping a diagram, or reading the words back out with /image-to-text, where clean letter edges help recognition. It is also the safer choice for pages with small print, fine lines or coloured text on a coloured background.

The resolution settings, file names, zip and page limits work exactly as on /pdf-to-jpg, where they are explained. To turn PNG images back into a PDF, use /png-to-pdf.
