PDF — every page becomes an image
What this page helps you do
Export PDF pages as PNG images for diagrams, screenshots or compositing where crisp rendered edges matter. The transparent-background option lets unpainted page areas remain transparent when the PDF content permits it.
How to use the result
Choose the pages and DPI, set the background option, and export. Test transparency against the background where the PNG will be placed, rather than judging it only in a white image viewer.
Before you rely on it
- Confirm the actual pixel dimensions and any reduced-DPI notice for oversized pages.
- Inspect text edges, white objects and transparent regions in the destination layout.
Limit to keep in mind: PNG is lossless for the rendered pixels, but rendering still converts vector content into a fixed-resolution image. Painted white areas stay white, and selectable PDF text is not retained.
Choose PNG for the rendered pixels you need
PNG is useful for text, diagrams and line art when JPEG artifacts would be distracting. It also supports a transparent background. Select the format required by the destination and compare the resulting size with its limit.
The export has fixed pixel dimensions. Rendering at a higher resolution can describe vector detail more closely, but enlarging a low-resolution scan does not create missing detail.
Distinguish an empty background from white content
The transparent setting applies to parts of the page where the PDF paints nothing. A white rectangle behind a diagram or white pixels inside a scanned image are still part of the content and remain in the PNG.
Place a sample export on its intended background before using a complete batch. Choose white explicitly when the receiving application needs an opaque image.
Keep resolution and file size proportionate
Use the displayed pixel dimensions to judge whether a resolution suits the job. More pixels require more memory and can produce much larger PNGs, particularly for noisy scans and photographs.
Inspect page edges and fine type in the saved output and read any reduced-resolution notice. Choose JPG when its smaller photographic output meets the need; choose PNG when transparency or avoiding another lossy encoding step matters.
Review an extracted graphic at its final size
A full-page export can be cropped to a diagram or logo in an image editor. Crop after checking the resolution needed for the graphic's final placement, rather than enlarging a tiny crop later.
This conversion prepares page images. It does not perform OCR, repair the source or preserve the original PDF's selectable text in the PNG.

Frequently asked questions
- Does the transparent option remove white objects?
- No. It keeps unpainted page areas transparent. White shapes or pixels already present in the PDF remain white, so check the image on the background where it will be used.
- What does lossless mean here?
- PNG compresses the rendered pixels without an additional lossy encoding step. The PDF page has still been rendered at a finite resolution, so the PNG is not a vector replacement and cannot recover missing scan detail.
- Why can a PNG be much larger than a JPG?
- Photographic texture, scan noise and shading can be expensive to store losslessly. Flat colours may compress well. The difference depends on the page and resolution; there is no fixed JPG-to-PNG size ratio.
- Can I export a diagram without the full document?
- Select its page, export at a suitable resolution and crop the PNG in an image editor. A transparent background can help with placement, but it does not remove content painted into the PDF.
- Can I select particular pages?
- Enter a range, such as 1-3, 7, to avoid exporting pages you do not need. Leave the range blank to process the whole document within the stated limits.
- Will transparency work in every application?
- Receiving applications handle transparency differently. Test the PNG where you plan to use it, and choose a white background here when an opaque image is required.
- Is the PDF uploaded?
- The browser renders and encodes its pages locally. Keep the source and compare the downloaded images before sharing or printing them.
