JPG is a "lossy" format. For chemical structures with sharp lines and text labels, PNG is often better than JPG because it preserves hard edges without artifacts. If your converter allows it, choose PNG instead of JPG for line art. Common Problems and Troubleshooting 1. "My JPG looks blurry or unreadable." Fix: Increase the DPI setting during export. Never take a screenshot of a small CDX file and enlarge it. Always export directly at high resolution. 2. "The background is black/transparent, but I need white." Fix: In ChemDraw, go to Object > Apply Color Scheme > Black on White before exporting. In online converters, look for a "Background" checkbox. 3. "My CDX file contains multiple pages/objects." Fix: Most converters only capture the first page or the active selection. In ChemDraw, group all objects ( Ctrl+G ), then export. 4. "I need to preserve chemical metadata." Warning: JPG does not store chemical structure metadata (like SMILES or InChI keys). If you need the chemical data, keep the original CDX file and export a JPG copy . CDX vs. CDXML: What's the Difference? You might also see CDXML files. This is the XML-based version of CDX. Most CDX converters also handle CDXML. If a tool says "CDX to JPG," it will likely accept .cdxml files as well. If not, simply rename .cdxml to .cdx (often works) or open it in ChemDraw and re-save as .cdx . Conclusion: Which Method Should You Choose? Let's summarize: | Your Situation | Recommended Method | |

Use cairosvg (Python library) combined with openbabel or a virtual print driver. However, the most reliable batch method is using ChemDraw's built-in batch converter (available in ChemOffice Professional) or a Virtual PDF Printer set to JPG output. Common Problems and Troubleshooting 1

Converting CDX to JPG is not difficult, but doing it correctly ensures your chemical structures look professional, whether on a poster, a website, or in a journal article.
