Format and Converter Selection

Select formats for conversion

Select “from” and “to” file formats in the “Convert from/to” boxes, in either order. Typing where indicated filters the options (case insensitive); for example, typing “can” or “NON” reduces the number of options to one: “can: Canonical SMILES.”

When converting multiple files with, say, extension cif within an archive (e.g., ZIP), select "cif: Crystallographic Information File."

If you change your mind about a conversion, click the “Reset” button.

When both formats have been selected, converters able to carry out this conversion appear in the “Conversion options” box below along with an indication of conversion quality (many conversions not yet tested) and whether or not the converter is supported on this site.

Note for mobile users: On phone and tablet browsers, the format selection will only update after you finish typing. In order to see the matching formats, you will then have to tap the selection box, which will bring up a list of the matching formats which you can select from.

Select a converter

Selecting a converter displays information about it, along with a link to a relevant website. Selecting a supported converter affords the opportunity to carry out a conversion on this site. Clicking on the “Yes” button takes us to the “Conversion” page. If a file format has not been found, or if there are no converters capable of carrying out a required conversion, please click on “Report Missing Format/Conversion” in the navigation bar.

Note for mobile users: On phone and tablet browsers, you will need to tap the select box to see a list of the available converters, which you will then be able to select from.
