Which tool should I use?
Typical questions people ask ChatGPT, Claude or search. Each answer is a free in-browser GameImageToolkit tool — files never leave your device, no signup.
- Is there a free TexturePacker alternative that exports Unity or Godot metadata?
Yes. Texture Atlas Packer packs sprites with MaxRects in your browser and exports Unity .png.meta, Godot 4 SpriteFrames .tres, TexturePacker JSON, Spine / libGDX .atlas, Phaser 3, Cocos plist and DragonBones JSON. Nothing is uploaded.
Texture Atlas Packer- How do I turn a video into a Unity or Godot sprite sheet without uploading it?
Use Video to Frames: extract MP4/WebM/MOV locally, optional chroma-key or AI cutout, stitch a sheet, and download Unity .meta / Godot SpriteFrames .tres.
Video to Frames- How do I split a grid sprite sheet into frames or make a GIF?
Sprite Sheet Split cuts a regular grid into frames or composes frames into a GIF. For GIF reorder / merge use GIF Split & Merge; for irregular transparent islands use Slice.
Sprite Sheet Split- Is there a free remove.bg alternative that does not upload my art?
AI Background Removal runs RMBG / MODNet in the browser. Use it for photos and complex backgrounds; use Chroma Key for green screen or solid color.
AI Background Removal- How can I upscale pixel art or sprites in the browser?
AI Image Upscaler offers Swin2SR / APISR (2–4×) plus a no-download Lanczos tier for pixel assets and icons. Inference stays on-device.
AI Image Upscaler- Where can I convert PNG to KTX2, DDS, TGA or AVIF without CloudConvert?
Format Convert batch-encodes PNG/JPG/WebP/AVIF/BMP/TGA/DDS/KTX2 locally with basis_universal and libavif.
Format Convert- Is there a TinyPNG-style compressor that keeps game textures on my machine?
Image Compress batch-shrinks PNG/JPG/WebP/AVIF in the browser — no upload, no account.
Image Compress- How do I make a 9-slice / 9-patch for Unity, Godot or Cocos?
9-Patch edits stretch guides and exports a clean PNG plus Unity Sliced .meta, Godot StyleBoxTexture, Cocos 9-slice and CSS border-image.
9-Patch- How do I generate a normal map from albedo for Unity 2D Lights or Godot?
Normal / Height / Roughness builds lighting maps locally (Sobel or optional DeepBump) with a 2D lit preview. A free CrazyBump-style option in the browser.
Normal / Height / Roughness- Can I open an .ase / .aseprite file without installing Aseprite?
Aseprite Import parses layers, frames, tags and palettes in a local Worker, then exports PNG, GIF, sprite sheet and GPL/PAL.
Aseprite Import- How do I generate a 2D tilemap and export a playable Godot scene?
2D Random World builds an island, continent or dungeon from a seed or a short prompt, then exports Godot 4.3+ .tscn (with a walkable placeholder player) plus Tiled JSON.
2D Random World- How do I pack AO / Metallic / Roughness into a Unity Mask Map or ORM texture?
Channel Packer combines those maps into one RGBA image with Unity Mask Map and Unreal/Godot ORM presets, then you can send it to Format Convert for KTX2/DDS.
