Convert PDF to PNG 2026 — Free Online

Convert PDF pages to PNG. The page opens on PNG at 2× scale, which keeps text edges crisp — PNG is lossless, so a diagram or a page of text comes out exactly as it was drawn.

Why PNG for text and diagrams

PNG stores pixels exactly. Nothing is approximated, so a black letter on a white background has a clean edge rather than the faint grey fringe JPEG leaves behind. For anything that will be read, zoomed into, or pasted into a document, that difference is visible.

The cost is size. A page of text as PNG is often several times larger than the same page as JPG, because lossless compression cannot do much with the fine detail of rendered type. For a handful of pages this rarely matters; for two hundred it does.

PNG also keeps transparency, so a page with a transparent background can be composited over something else rather than arriving on a white rectangle.

  • Lossless — no artefacts around text or line art
  • Larger files than JPG, sometimes several times
  • Keeps an alpha channel, so transparency survives

Scale is what decides sharpness

A PDF page has no resolution of its own — it is drawn from instructions, and the scale you choose is what turns it into pixels. 1× produces an image matching the page's nominal size, roughly 72 DPI. 2× is about 144 DPI and is the default. 3× is around 216 DPI and is worth it when the output will be printed or zoomed.

Higher scale means proportionally more pixels, so a 3× image is around nine times the area of a 1× one. Choose it deliberately rather than by default, especially with many pages.

What comes out

One PNG per page, at the scale you chose, in the same order as the document. Select pages before converting if you only want some.

Text in the images is a picture of text — it cannot be searched or copied. If you need the words rather than the pages, the image-to-text tool runs OCR and is the right route.

Frequently Asked Questions

Why is my PNG so much larger than a JPG would be?

PNG is lossless, so nothing is approximated. Rendered text is fine detail that lossless compression cannot reduce much, which is why the same page can be several times larger.

What DPI do I get?

It depends on the scale. 1× is roughly 72 DPI, 2× about 144, and 3× around 216. A PDF page has no resolution of its own until it is rendered.

Does PNG keep transparency?

Yes. PNG has an alpha channel, so a page with a transparent background stays transparent rather than being filled with white.

Can I search the text in the output images?

No — the text becomes a picture of text. Run the images through the image-to-text tool if you need the words back.

Should I use 3× scale?

Only when the result will be printed or zoomed into. A 3× image has about nine times the pixels of a 1× one, which adds up quickly across many pages.
