Free Online Texture Resizer & Converter
Resize textures to power-of-two sizes for 3D engines, convert between PNG, JPG, and WebP — all in your browser with no uploads.
Supported Operations
Everything you need to prepare textures for game engines, WebGL, and AR/VR.
Resize to any resolution
Use preset power-of-two sizes (128–4096 px) or enter a custom width and height. Lock aspect ratio to avoid distortion.
Format conversion
Convert between PNG, JPEG, and WebP. Choose JPEG or WebP for smaller file sizes, PNG for lossless with transparency.
Quality control
Adjust JPEG/WebP compression quality from 10% to 100%. Lower values trade quality for significantly smaller files.
Batch-ready workflow
Process one texture at a time with instant results. No account, no queue, no waiting.
Why Use This Tool
Fully private
Canvas API processing runs locally. Your textures never touch a server.
Instant conversion
Even 4K textures process in under a second on modern hardware.
Works everywhere
Any modern browser on desktop or mobile — no Photoshop or plugins required.
Frequently Asked Questions
Why do 3D engines need power-of-two textures?
Most GPUs handle textures most efficiently when dimensions are powers of two (128, 256, 512, 1024, 2048, 4096). Non-power-of-two textures may disable mipmapping, increase memory usage, or cause rendering artifacts in engines like Unity and Unreal.
What formats can I convert to?
You can export to PNG (lossless, supports transparency), JPEG (lossy, smallest file size), and WebP (modern format with great compression and quality). WebP is ideal for web delivery.
Does resizing up (upscaling) improve quality?
No. Upscaling adds pixels by interpolation but cannot recover lost detail. Always start from the highest resolution source you have.
Is there a maximum file size?
There is no hard limit. Large images (4K+) may take a second or two to process depending on your device. All processing runs locally in your browser.
Does my file get uploaded?
No. All resizing and conversion runs locally via the browser Canvas API. Your image data never leaves your device.
