Laby Skin Studio vs Nova Skin

Laby Skin Studio is a browser editor for building Minecraft skins pixel by pixel, with a rotating 3D model and a flat 2D texture view that remain synchronized. You can start with Steve or Alex, upload a skin PNG, or select one from the Laby library and combine body parts from different skins. Editing layers can be reordered, hidden, renamed, and adjusted for opacity and blend modes. Drawing options include brushes with different shapes and sizes, fill modes, auto-tone shading, a clone stamp, lasso and magic wand selections, and symmetry. Filters include grayscale, colorize, brightness, contrast, saturation, hue shift, posterize, outline, and gradients with dithering. The editor switches between classic Steve and slim Alex models. It saves work, including layers, in the page URL and exports a 64×64 PNG for Minecraft: Java Edition. Its touch-optimized layout supports phones and tablets, using one finger to paint and two to rotate or zoom. It is free, with no account needed.

Nova Skin is a browser-based tool for creating and editing Minecraft skins. You can paint on a 3D model, letting you see the skin on a character as you work. It supports the Slim (Alex) model and can load a skin by username. The model can also be posed and animated, adding ways to view a skin beyond a static preview. The listed workflow stays in a browser: open Nova Skin, load a skin by username if needed, then paint on the 3D model and use its posing or animation features. Nova Skin is free to use, and a free plan is listed. It runs on Browser; no other platform is specified.
