Export diagrams and charts from a PDF as PNG
Charts, technical drawings and diagrams have thin lines and flat colours. Saved as JPG they pick up fuzzy edges and smudges around text. PNG is lossless, so lines and labels stay crisp.
PDF to PNG renders the pages you choose as PNG images in your browser, ready to paste into a report, a wiki or a slide.
When you paste a chart into another document, check the licence or permission for the original PDF, particularly for published reports. Inside your own organisation, exporting diagrams as PNG is a reliable way to reuse them in wikis, tickets and slide decks without retyping labels or redrawing shapes, and the lossless format means repeated editing does not gradually degrade the image.
Step by step
- Open PDF to PNG and add the PDF that contains the chart.
- Select the page with the diagram.
- Choose a high resolution if the image will be shown large or printed.
- Convert, download, and crop to the chart in any image editor.
Tips
- Use PNG for graphics and text, JPG for photographs.
- PNG files are larger than JPG; that is the cost of keeping every pixel.
- If the file is too big for a website, convert it to WebP afterwards.
Questions
- Does PNG have a transparent background?
- The page is rendered as it appears in the PDF, normally with its white page background.
- Can I export several pages at once?
- Yes. Select multiple pages and download them together as a ZIP.
- Why choose PNG over JPG here?
- PNG is lossless, so thin lines and small labels stay sharp.
