How to Rip Textures with CrunchyRip

❗ What is this?

CrunchyRip is a tool for Game Devs & Artists. Use it to extract clean, flat textures from skewed photos of real-world surfaces like signs, brick walls, or murals!

1. Opening Source

Click 📁 "Open Image" to load your texture sheet. Processes are 100% local; your files never leave your browser.

2. Defining a Quad

Click ➕ "New Quad Layer". Click 4 points on the canvas to define the corners. Order matters: TL, TR, BR, BL works best!

3. Perspective

Check the 👁️ Live Preview. The tool calculates the "Natural Aspect Ratio" automatically based on your quad shape.

4. Atlas Workbench

🔨 "Rip to Atlas" sends it to the 🎨 Workbench. Open it to arrange chunks. Use Arrows to nudge or snap.

5. Exporting

Click 💾 "Process & Export" to get your PNG atlas and JSON file, or go for individual files!

6. Project Bundles

Use 💾 "Save Project" to download your workspace as a .json file. Use 📂 "Load Project" to restore all layers, images, and your queue instantly!

📐 About Homography

This tool uses a Homography Algorithm to map skewed coordinates to a 2D plane. By calculating a 3x3 transformation matrix, we "warp" your 3D perspective photo back into a flat, 2D texture.

🔒 Why a Client-Side Texture Ripper?

🕵️ Your Images Stay Private

Server-based image tools upload your files — artwork, reference photos, game assets — to infrastructure you don't control. CrunchyRip processes entirely in your browser. Nothing is ever transmitted. Your assets belong to you alone.

⚡ Instant Processing

No upload round-trip. No server queue. Homography calculations and canvas warping happen the moment you adjust a handle — powered by your own CPU and the HTML5 Canvas API. Results are live and immediate.

🌐 Works Offline

Once the page loads, CrunchyRip works without any internet connection. Rip textures in the field, on a plane, or in a studio with no Wi-Fi. Save your project file and continue anywhere.

📦 Full Workflow, Zero Cost

Layer management, quad selection, live preview, atlas workbench, ZIP export, project save and load — CrunchyRip is a complete texture pipeline with no subscription, no premium tier, and no catch.

💸 Always Free

No accounts. No watermarks. No "export limit reached." CrunchyRip is permanently free for personal use, supported only by non-intrusive display advertising. Rip as many textures as you like.

🔓 Open Tech Stack

Built on the HTML5 Canvas API and a pure JavaScript homography engine. No proprietary SDK, no third-party image processing service. Every pixel transformation is computed locally and is fully auditable in the source.

💡 Tips for Better Texture Rips
1
Place quad points in TL → TR → BR → BL order — CrunchyRip uses this winding order to compute the homography matrix correctly. Mixing up the order produces mirrored or scrambled output. The Live Preview will show the result immediately.
2
Trust the Natural Aspect Ratio — CrunchyRip calculates the true undistorted dimensions of your quad automatically. This prevents the common mistake of manually stretching a ripped texture to "look right" when it's already geometrically correct.
3
Use ECL H in the Atlas Workbench for overlapping textures — when packing multiple rips into a single atlas sheet, leave at least 2px gutter between chunks to prevent texture bleeding when using mipmaps or bilinear filtering in your engine.
4
Save your project often — CrunchyRip autosaves to sessionStorage, but a hard browser crash won't recover that. Use 💾 Save Project regularly when working with many layers to get a portable .json file you can reload at any time.
5
Shoot source photos square-on with good lighting — the closer your photo is to a frontal view with even lighting, the less distortion the homography has to correct and the cleaner the ripped texture will be. Avoid strong shadows crossing the target surface.
6
Use the Global Output Cap to control atlas size — set the W/H cap before ripping to guarantee your textures don't exceed a specific resolution. Useful for keeping mobile game assets under texture size limits (e.g. 1024×1024 for older devices).
❓ Frequently Asked Questions
Yes — completely free with no premium tier, no watermarks, no export limits, and no sign-up required. CrunchyRip is supported by non-intrusive display advertising.
Never. All processing — loading, quad selection, warping, and export — happens locally using JavaScript and the HTML5 Canvas API. Your images do not leave your browser at any point.
A homography is a mathematical transformation that maps one plane to another in 3D space. CrunchyRip calculates a 3×3 transformation matrix from your 4-point quad selection and uses it to "unwarp" the perspective distortion, producing a flat, undistorted texture as if you were looking at the surface head-on.
When you photograph a surface at an angle, the image is distorted — a square tile may appear as a trapezoid. CrunchyRip analyses the geometry of your quad to calculate the true, undistorted width-to-height ratio of the surface, so the exported texture has the correct proportions without manual adjustment.
The Atlas Workbench is a visual layout tool where you can arrange multiple ripped textures onto a single canvas sheet. Drag and resize chunks, use Auto-Pack for automatic arrangement, set a gutter between tiles, and export the entire atlas as a single PNG with an accompanying JSON metadata file.
CrunchyRip exports textures as PNG files — either as individual files (one per quad), or as a single combined atlas PNG with a JSON metadata file describing each tile's position, size, and name. Both modes are available from the Export Mode selector in the right sidebar.
A Project Bundle is a .json file that saves your entire CrunchyRip workspace — source images, quad layers, positions, the export queue, and Atlas Workbench layout. Load it back at any time to resume exactly where you left off. Great for multi-session work on large texture sets.
Yes. Add multiple Quad Layers to the same source image — each defines a different region. Rip each layer to the Atlas queue individually, then open the Atlas Workbench to arrange all rips onto a single output sheet.
Yes. Once the page has fully loaded, all texture ripping, layer management, atlas packing, and export features work without an internet connection. Only the visitor counter and ad units require connectivity.
CrunchyRip works on any modern browser: Chrome 100+, Firefox 100+, Safari 15+, Edge 100+, and Brave. Internet Explorer is not supported. A desktop or laptop is recommended for the best experience with the canvas workspace.
