Sprite Sheet Editor

Sprite Sheet Editor is a free, browser-based tool for game developers and pixel artists who work with sprite sheets. No downloads, no installs, no account required — just open the page and start working.

Demo: https://sprite-sheet-editor.vercel.app/

Load any PNG or JPG sprite sheet, configure the frame grid to match your layout, and instantly preview your animation at any speed. The built-in pixel editor lets you make per-frame corrections directly in the browser, with a full suite of drawing tools, an advanced color picker, and undo/redo history. When you're done, export a clean, re-packed sprite sheet containing only the frames you need.

Key highlights:

• Drag and drop your sprite sheet directly onto the page to get started
• Set rows, columns, and edge padding to perfectly align the frame grid with your sheet
• Preview animations in real time with adjustable FPS, zoom, pan, and a timeline scrubber
• Edit individual frames with pencil, eraser, flood fill, box select, and eyedropper tools
• Replace or remove any color across a single frame or the entire sheet — great for chroma keying a background out of sprites exported from 3D software
• Export a freshly packed PNG with only your selected frames, in any row layout you choose
• Your entire workspace — image, settings, tool state, and UI layout — is saved automatically so it's right where you left it every time you return
