Is the sprite sheet cutter free?
Yes. Slicing, review, portable JSON, Godot 4, and Unity exports all run locally in the browser with no credits and no upload.

Sprites in a side-scrolling level
Check how animation poses, foreground obstacles, and background contrast support the action.

Compare the character's proportions, colors, and action silhouettes with the world around it.

A practical example
Slice the downloadable eight-frame sheet
Use a concrete input, inspect the output, and check the current limits before choosing your next step.
Example input
Use the transparent 128 × 64 demo PNG below. It contains four columns and two rows of 32 × 32 cells, with no margin or spacing.
What to check
- Download the demo, choose it in the slicer, and set 4 columns and 2 rows. Leave outer margin and spacing at 0.
- Confirm that the overlay surrounds each entire character. Preview the frame order and adjust the shared ground pivot if your animation requires it.
- Export PNG frames or an atlas package. Check frame dimensions, names, timing, and pivots before importing into your project.
Expected output
This source grid contains eight 32 × 32 cells. With trimming disabled, each exported frame keeps that canvas size; enabling trimming changes the visible bounds.
Current limits
A grid slices the existing artwork; it does not create missing poses. Godot SpriteFrames stores animation timing, while the exporter keeps pivot information as metadata for your own placement checks.

01 / WHY IT WORKS
Made for production, not just previews.
Review before export
Preview timing, reorder frames, repair pixels, and set a precise shared pivot.
Engine import packages
Pack trimmed frames with padding and export portable JSON, Godot 4, or Unity files.
From source to clearly labeled output.
Drop a sheet
Choose a PNG, WebP, or JPG sprite sheet.
Review the animation
Confirm the grid, play the result, repair or reorder frames, and set the ground pivot.
Export to your engine
Download individual frames, an atlas and metadata, or a Godot 4 or Unity package.
03 / FAQ
Clear terms before you build.
Does this upload my sprite sheet?
No. Slicing happens locally in your browser and does not use generation credits.
Can it preserve transparency?
Yes. PNG and WebP transparency is preserved in each exported PNG frame.
What if my sheet has padding?
Set the outer margin and spacing in whole pixels. The live overlay shows the exact cells before anything is sliced.
Do I need an account to export?
No. The complete local pipeline—including portable, Godot 4, and Unity ZIP exports—is free and does not use credits.
