Chemix can save your diagrams in various image formats.
Here's the brief summary:
- If you are posting to Twitter or social media, choose JPG as they have a white background. PNGs will look bad.
- PowerPoint on Windows may not support SVGs well. Choose JPG, or PNG if you need transparency
Most versatile image format. It can be used in variety of documents, PDFs, Google Docs, presentations, uploaded to Dropbox, Google Drive as well as shared over email. Since the image will have a white background, it is best for documents or presentations with a white background.
Chemix will export your image to JPG at highest possible zoom level which results in a high-resolution image.
Another versatile image format, recommended over JPG if you need transparency, e.g. if your document or presentation has a background that is not white or you plan to add other images. Images exported in PNG can be used in variety of documents, PDFs, Google Docs, presentations, uploaded to Dropbox, Google Drive as well as shared over email.
Chemix will export your image to PNG at highest possible zoom level which results in a high-resolution image.

Unlike PNG, which is a raster format, SVG is a vector format. Instead of storing colour values for individual pixels, SVG stores the points and curves that make up the image. Therefore, SVG images can be scaled indefinitely, without loss of detail. For Chemix diagrams, this also usually results in SVG files being smaller.
However, SVG files are not universally supported and depending on where you plan to use your diagram, it may not display correctly. Text may also appear differently depending on where it's opened.
