Output Format
Defaultwebp
Choose the output format. PNG is lossless with transparency; JPEG is lossy without transparency; WebP is lossy with transparency; KTX2 is GPU-compressed texture.

About This Tool
Convert between PNG, JPEG, WebP and KTX2 formats. Resize images to any dimensions, adjust output quality, and compress textures to GPU-friendly KTX2 optimized for 3D engines and games. Everything runs locally in your browser — nothing is uploaded to a server.
Tips
- 1KTX2 dramatically reduces texture size for 3D and game engines
- 2ETC1S mode gives the smallest files; UASTC gives higher quality
- 3JPEG does not support transparency — transparent areas become white
- 4Resize fields are linked by aspect ratio by default

Output Dimensions
Set the width and height of the output image. Defaults to maintaining aspect ratio — changing one value auto-scales the other.

Frequently Asked Questions
About this tool
Q
What is KTX2 and why use it?
A
KTX2 is a GPU-compressed texture container using Basis Universal. Textures stay compressed on the GPU, saving memory and bandwidth — essential for 3D engines and games. This tool can encode PNG/JPEG/WebP to KTX2 and decode KTX2 back to PNG.
Q
What's the difference between ETC1S and UASTC?
A
ETC1S is a block-compressed mode producing the smallest files at the cost of some quality. UASTC is a near-lossless mode with higher quality but larger files. Use ETC1S for most cases, UASTC when quality matters most.
Q
Why does my JPEG lose transparency?
A
JPEG does not support alpha transparency. When converting to JPEG, transparent pixels are filled with white. Use PNG or WebP to preserve transparency.
Q
Is my image uploaded anywhere?
A
No. Conversion, resizing and KTX2 encoding/decoding all happen locally in your browser. Nothing is sent to a server.
General questions
Q
Is Any3D completely free?
A
Yes, Any3D's core features are free to use forever. We provide format conversion, model optimization, and online preview at no cost, with no registration required.
Q
Are my files uploaded to your servers?
A
No. Files you select are processed only in your browser on this device—they never leave your device and are never sent to our servers. We don't store any user files; after processing, related data in browser memory is released.
Q
Do I need to install software?
A
No installation required. Any3D is entirely browser-based—just open the webpage to use all features. It works on Windows, Mac, Linux, and other major operating systems.
Q
Is there a file size limit?
A
The processing capacity depends on your device performance and the model's vertex count and texture complexity, rather than file size alone. We impose no file size limit, but when a model exceeds what your device can handle, the page may lag or even crash.
