Convert PDF to PNG Online
Convert PDF pages to PNG images online — free and without any sign-up.
Select conversion type:
PNG is the format of choice when image quality and sharpness matter more than file size. Unlike JPG, which uses lossy compression that subtly degrades image quality, PNG uses lossless compression. This makes PNG the right choice when converting PDF pages that contain sharp text, technical diagrams, line drawings, charts, or any content where crisp edges are important. PNG also supports full transparency, which means pages with transparent backgrounds will convert correctly without being filled with a background colour. Dockitt converts your PDF pages to PNG directly in your browser using PDF.js.
How to use
- Click 'Choose PDF' and select the PDF file you want to convert to PNG images.
- Click 'Convert to PNG' and wait while each page is rendered at full quality.
- Download the PNG images. Each page becomes a separate lossless PNG file.
FAQ
When should I use PDF to PNG instead of PDF to JPG?
Use PNG when your PDF contains sharp text, technical drawings, charts, logos, or any content with hard edges and solid colours. PNG is lossless, meaning every pixel is preserved exactly as rendered. Use JPG when your PDF is mostly photographic content and you need smaller file sizes. The visual difference is most noticeable on text and line art, where JPG compression can create subtle blurring around edges.
Does PNG support transparency?
Yes. PNG fully supports alpha channel transparency. If your PDF pages have transparent backgrounds, the PNG output will preserve that transparency correctly. This is one of the main advantages of PNG over JPG for certain types of content, particularly graphics and designs that need to be placed on different backgrounds.
The PNG files are very large. Is this normal?
PNG lossless compression produces larger files than JPG, especially for pages with complex colour content or large dimensions. This is a natural trade-off for the higher quality. If file size is a concern and the content does not require transparency or pixel-perfect sharpness, consider using the PDF to JPG conversion instead for a smaller output size.
Will each page become a separate PNG file?
Yes. Each page of the PDF is exported as an individual PNG image. A 5-page PDF produces 5 separate PNG files. There is currently no option to combine all pages into a single image file.
Can I use the PNG images in presentations or documents?
Yes. PNG is one of the most universally supported image formats. You can insert the resulting images into Microsoft Word, PowerPoint, Google Docs, Google Slides, Keynote, Figma, or any other application that accepts images. The images will display at full quality in any of these applications.
Is the conversion done in my browser or on a server?
The PDF to PNG conversion is handled entirely in your browser using PDF.js. Your file is not uploaded to any server and stays on your device throughout the process. This makes it faster for most files and means your document content is never transmitted over the internet.
