Question 1

How does the tool handle variable frame delays in a GIF?

Accepted Answer

Currently, the tool extracts all frames into a uniform sprite sheet. If your original GIF uses variable frame delays, you will need to re-apply those specific timing values within your game engine using the exported JSON coordinate data.

Question 2

Is this the same as a local CLI no-upload converter?

Accepted Answer

No. This page is a browser-local GUI: after the page loads, your GIF is processed on your device in the browser. If you need a terminal or CI workflow, use ImageMagick or FFmpeg locally instead.

Question 3

Which coordinate data format should I choose for Godot?

Accepted Answer

For Godot, start with the PNG sheet. If frames are uniform, slice with SpriteFrames or Sprite2D regions. XML or JSON metadata only helps when your project uses an addon, plugin, or custom GDScript parser.

Question 4

Why do some extracted frames have black backgrounds instead of transparent?

Accepted Answer

This usually occurs if the original GIF was optimized using a specific disposal method without a global color table. Our parser handles most transparency correctly, but highly optimized legacy GIFs might require flattening before upload.

Question 5

What is the max GIF size and frame count this tool can handle?

Accepted Answer

Practical ceiling is around 200MB per GIF or about 500 frames at 1024x1024 resolution — the actual limit depends on your device's available RAM. Chrome typically handles the largest files because of its V8 memory headroom. If the browser tab crashes, pre-crop or trim the GIF before upload.

Question 6

Which game engines can import the exported JSON and PNG?

Accepted Answer

JSON Hash is the safest default for Phaser 3 and common PixiJS TexturePacker-style atlas workflows. CSS output is for web background-position animation. Unity and Godot often use their editor slicing workflows unless a compatible XML/JSON importer is installed.

Question 7

How do I fix texture bleeding on the extracted sprite sheet?

Accepted Answer

Before exporting, raise the Padding value in the parameters panel to 2 pixels (or 4 if you use mipmaps). Bleeding is caused by GPU bilinear sampling pulling color from adjacent frames — padding inserts a transparent buffer. In Unity, also check 'Filter Mode: Point' on the sprite import for pixel-art GIFs.

Question 8

What file formats can I import?

Accepted Answer

This page is optimized for animated GIF input, including GIF87a and GIF89a files. The shared tool tabs on the same interface also accept PNG, JPG, JPEG, WebP, and SVG when you switch back to the image-to-sprite-sheet workflow.

Question 9

What's the max image or sheet size?

Accepted Answer

Plan around ~200MB per source file and a practical output ceiling around 8192x8192 on desktop GPUs or 4096x4096 on many mobile GPUs. The exact limit depends on browser memory and your device's graphics hardware.

Question 10

Does it work offline?

Accepted Answer

Mostly yes. Once the page and JavaScript bundle have loaded, frame extraction and packing run locally in your browser with no server round-trip. If you revisit before the cache is cleared, the tool often works offline for repeat use.

Question 11

Is there a command-line version?

Accepted Answer

No. Sprite Sheet Maker is a browser GUI only — there is no CLI or CI build integration today.

Question 12

Does it support polygon packing or multipack?

Accepted Answer

No. The tool focuses on rectangular sprite sheet workflows, not polygon mesh trimming or automatic multi-atlas output. If you need polygon packing or multipack, use a desktop packer like TexturePacker.

Question 13

Is the tool free for commercial use?

Accepted Answer

Yes. Sprite Sheet Maker is free to use commercially with no account, no watermark, and no per-project license fee.
