Convert PDF to PNG
Convert selected PDF pages to lossless PNG images for free. Preview pages, choose 150–300 DPI, and download privately—no upload, login or watermark.
Private by design: your PDF and PNG pages stay in this browser. DraftFort never receives the file.
Convert selected PDF pages to lossless PNG images
PNG is useful when a portal, presentation, design tool or publishing workflow needs a sharp image instead of a PDF. It uses lossless image encoding, which helps preserve crisp edges in text, diagrams, screenshots and line art without the block or halo artifacts that lower-quality JPEG compression can introduce.
DraftFort opens the PDF and renders the pages you select entirely in your
browser. A one-page selection downloads as a .png file. Multiple selected
pages are packaged in a ZIP with the original PDF page number in each filename.
The source file is not uploaded or changed.
How to convert PDF to PNG
- Choose a PDF. Drop the document into the tool or browse on your device.
- Check the previews. All pages start selected; clear and choose again if you only need certain pages.
- Keep PNG selected. You can switch to JPG from the same interface when a smaller photographic file matters more than lossless edges.
- Choose a resolution. Use 150 DPI for lighter screen images, 200 DPI for the recommended balance, or 300 DPI for detailed output.
- Download. Save one PNG directly or several numbered PNGs in one ZIP.
Pages are processed sequentially to limit peak memory use. Large PDFs and 300 DPI output may still work better on a computer than a phone.
PDF-to-PNG resolution guide
| Intended use | Resolution | Expected result |
|---|---|---|
| Messages, previews and ordinary screens | 150 DPI | Smaller dimensions and file size |
| Slides, forms and everyday document reuse | 200 DPI | Recommended clarity/size balance |
| Detailed diagrams, fine text or printing | 300 DPI | Most pixels, largest files and memory use |
DPI controls how many pixels are created from the PDF page. PNG itself is lossless, but it cannot recreate detail that was missing from a low-resolution scan. Increasing DPI on a blurry scan produces more pixels, not new source detail.
PNG or JPG: which output should you use?
Choose PNG for text-heavy pages, diagrams, UI screenshots, logos and line art where sharp edges matter. Choose JPG for photographic pages or when a smaller file is more important than lossless encoding. The PDF to JPG converter provides adjustable JPEG quality for that trade-off.
PNG files are often larger because they preserve pixel data without lossy JPEG compression. Neither format keeps selectable text or PDF-specific structure. Both are pictures of the rendered page.
What the conversion preserves—and what it flattens
The PNG should visually match the ordinary white-background page at the chosen resolution. It does not extract the original images stored inside the PDF; it renders the complete page, including text and graphics, into one pixel image.
PDF links, form controls, comments, layers, bookmarks, attachments, digital signatures and accessibility structure do not become interactive PNG features. Keep the original PDF as the authoritative copy, especially when searchability, verification or accessibility matters.
Private browser-based rendering
After you choose the file, DraftFort loads its PDF renderer, draws selected pages to browser canvases, encodes PNG bytes locally and passes them to the browser download system. There is no DraftFort document-processing endpoint in this workflow.

Frequently asked questions
How do I convert a PDF page to PNG?
Add the PDF, preview and select the pages you need, choose 150, 200 or 300 DPI, confirm PNG as the output format, and download. One selected page downloads directly; several pages download in a ZIP.
Does DraftFort upload my PDF?
No. PDF.js opens the document and your browser renders and encodes each selected page locally. DraftFort does not receive or store the PDF or PNG files.
Is PNG lossless?
PNG encoding is lossless, so it does not add JPEG-style compression artifacts. The PDF page is still rasterized into pixels at the selected resolution, so the PNG is not a replacement for the original vector PDF.
Can I convert only one page?
Yes. Clear the selection, choose the page you need, and download it as one numbered PNG. You can also select any combination of pages for a ZIP archive.
Which DPI should I choose?
Use 150 DPI for smaller screen images, 200 DPI for a balanced default, or 300 DPI for fine text, diagrams and print-oriented reuse. Higher DPI needs more memory and creates larger files.
Does the PNG have a transparent background?
No. DraftFort renders each complete PDF page on a white background so it matches normal document viewing. It does not attempt to infer or remove the page background.
Will PDF text stay selectable in the PNG?
No. PNG is an image format. Text, links, form fields, accessibility tags and other PDF features become pixels or are not carried into the image. Keep the original PDF when those features matter.
Can it open a password-protected PDF?
No. The converter does not bypass encryption. If you are authorized to use the file, remove protection through the document owner's approved method before converting.
