How do I convert PDF pages to PNG images?

Load the PDF, leave the page field empty for every page or enter something like 1,3,5-10, choose a resolution in DPI, then convert. Each page is rendered in your browser and saved as a lossless PNG — one page downloads as a single image and several pages download as a ZIP. The PDF itself is never uploaded.

About the PDF to PNG Converter

Use this PDF to PNG converter to export document pages as crisp, lossless images for slides, websites, annotations, or image editing. Convert every page or enter a page range, choose the output resolution in DPI, and keep a transparent background when the source supports it. The PDF is rendered locally in your browser and is not uploaded.

  • Export a chart, diagram, or selected document page as a sharp PNG for a presentation or report.
  • Convert every page of a short PDF into images for a website, content system, or annotation workflow.
  • Create lossless page images for editing when JPG compression artifacts would make small text less clear.

Why choose PNG instead of JPG for PDF pages?

Because PNG is lossless, and PDF pages are mostly text and line art — exactly the content JPEG compression handles worst. JPEG artefacts cluster around high-contrast edges, so small type picks up a grey halo and thin rules turn fuzzy. PNG stores the rendered page pixel for pixel, which is what you want for documentation screenshots, figures going into slides, or page images you intend to annotate or crop afterwards.

What DPI should you choose for PDF pages?

DPI decides how many pixels each inch of the page becomes, which sets both sharpness and file size. The default of 150 DPI renders a Letter page at 1275 × 1650 pixels, comfortable on screen and in slides. Choose 300 DPI when the image will be printed or when small print has to stay legible after cropping, and 72 or 96 DPI for quick previews and web thumbnails. Each step up multiplies the pixel count, so 300 DPI produces four times the data of 150.

When does the transparent background option help?

Only when the PDF page itself has no painted background. By default the renderer fills the page white before drawing, which is what you want for ordinary documents. Turn transparency on when you are lifting a logo, diagram, or signature off a page so it can be composited onto a coloured slide or another document without a white rectangle around it. Pages that do paint their own background will still come out opaque.

Are my files uploaded when converting PDF to PNG?

No. Rendering is done by a PDF engine running inside this tab, so no page image and no copy of the document is transmitted. That is the difference that matters when the PDF is a contract, a payslip, or an unreleased design: an upload-based converter has to hold your document long enough to rasterise it, and this one never receives it in the first place.

Need the images in another format afterwards — ICO, Base64, or format cleanup? Unheic, a sibling site, converts images free in your browser.

Frequently Asked Questions

Can I choose which PDF pages become PNG files?
Yes. Leave the Pages field empty to convert the full document, or enter selections such as 1,3,5-8 to export only those pages. One selected page downloads as a PNG; multiple pages download together as a ZIP.
What DPI should I use for PDF to PNG conversion?
Use 150 DPI for a practical balance of detail and image size. Choose 300 DPI for print work or pages with small text, or drop to 72 or 96 DPI when a smaller web image matters more.
Does PDF to PNG preserve a transparent background?
Enable Transparent background when you do not want the renderer to add white behind the page. Visible white artwork already contained in the PDF remains visible.
Is my PDF uploaded to create the PNG images?
No. Each page is rendered inside your browser, so the source PDF remains on your device during conversion.
