Sprite Editor

Sprite Editor is a pixel art sprite and animation editor that works only in your browser.
No installation required—you can start creating pixel art right away.

You can choose canvas sizes from 16/32/48/64/128 px, and freely change them even while editing.
It supports animations with up to 4 layers and up to 8 frames, with playback preview available at 1–30 fps.

Colors can be selected from the NES 64-color palette, and a color picker is also available for specifying custom colors.
It also includes a feature to make the currently selected color transparent.

For editing features, it supports rotation at any angle, flipping, rectangular selection, copy, cut, and paste.
The paste function also allows you to import images copied from other applications.
Additionally, it supports up to 50 levels of Undo/Redo, so you can edit with confidence while experimenting.

When you log in with your Google account, your work is automatically saved.
Saved works can be reopened anytime from the list panel on the left sidebar, duplicated, or exported as sprite sheets.

Even without logging in, you can use all editing features and PNG export.
Please feel free to try it out first.
