THREE SIMPLE STEPS

How to use the PDB Viewer

01

Open the structure

Download a PDB or mmCIF file from a structure database and drop it here, or open the crambin sample.

02

Explore

Switch between cartoon, ball and stick and space-filling, add a surface, and colour by chain, secondary structure, residue or B-factor.

03

Find and measure

Click residues in the sequence to zoom to them, label them, and measure distances, angles and dihedrals between atoms.

PDB Viewer FAQ

Is the PDB viewer free?

Yes, with no account and no limits beyond your device's memory.

Does it download structures from the PDB?

No. Download the file from a structure database yourself and open it here; the viewer reads it in your browser and never uploads it.

How big can the file be?

Typical proteins and complexes open in a second or two. Very large assemblies with hundreds of thousands of atoms work on desktops but can be slow on phones; turn the surface off for those.

Are ligands and waters shown?

Ligands are drawn as ball and stick on top of the cartoon and listed in the panel; waters are hidden from the ligand list and the sequence.
