Convert a MOL file to PNG or SVG
Free, no sign-up. It runs in your browser on Athanor’s own engine, and your structures never leave your device.
MOL file
PNG and SVG
The result appears here, with a picture of every structure.
How to do it
Open a .mol file or paste its text.
Press Convert. Athanor draws it in the ACS Document 1996 style.
Download the PNG, or the SVG for a picture that stays sharp at any size.
A publication drawing, not a screenshot
Athanor draws the structure with ACS Document 1996 settings: the bond length, line width and Arial labels journals ask for. The SVG keeps every line as a vector, so it scales for a poster or a slide without blurring; the PNG is ready for documents and chats.
What a conversion keeps
Athanor’s engine was checked on 1,222 structures from its own library, each sent from SMILES to a MOL file and back, and compared by RDKit with stereochemistry included: 1,212 came back as exactly the same molecule, with every R/S and E/Z label. The ten that did not show the three gaps the engine still has: a radical (as in nitric oxide or TEMPO) is not yet written into MOL files; the E/Z of a double bond inside a very large ring can be lost; and a metal sandwich compound such as ferrocene is written with multi-center bonds, which some programs read differently. The converter reads every MOL file it writes back again and marks any structure that does not come back the same.
