Why convert PDF to PNG?
The PDF is sealed — you can read it but you can't easily extract its contents. PDF-to-PNG breaks that seal, giving you each page as a standalone image you can use wherever you like.
The most common use case: someone sends you a PDF and you need one of its images, charts, or slides somewhere else. You can't screenshot it cleanly across all systems. You can't paste it into an app that doesn't accept PDFs. But if you convert the page to PNG, you can drop it into Canva, Figma, Instagram, PowerPoint, or any tool without friction.
This is also how designers extract presentation slides, book covers, and infographics from PDFs — the resulting PNG can go anywhere a raster image can go.
What you get: one PNG per page. A 10-page PDF produces 10 PNGs, numbered in order. We render at 150 DPI by default, which is sharp and web-ready. Pro users get up to 300 DPI — suitable for print-quality output.
Common reasons to convert PDF to PNG:
- ›Extracting a slide, chart, or diagram from a presentation PDF
- ›Getting a shareable image from a PDF you received
- ›Creating a thumbnail or preview image from the first page of a document
- ›Using a PDF cover or poster design as a social media image or email header
Quality & file size: PDF to PNG
Quality here is entirely a resolution decision. Each PDF page is rendered (rasterised) to a PNG at a fixed DPI — 150 by default, which is crisp on screen and web-ready, or up to 300 for Pro, which is print-sharp. The higher the DPI, the more detail and the larger the file: a text-heavy page might be 100–300 KB at 150 DPI and 2–4× that at 300 DPI.
One thing to understand: rasterising is a one-way step. Vector text and shapes in the PDF become a flat grid of pixels, so the PNG looks identical at 100% but won't stay razor-sharp if you scale it up later — pick a DPI high enough for your largest intended use. PDF pages render onto a white background by default (PDF image output has no alpha channel), so the PNG won't be transparent unless you need it and the page allows it. For a page that's essentially one photo, converting to JPG instead gives a much smaller file.
