Output Dimensions
Set the output width and height. Square presets (e.g. 1024×1024) suit texture workflows; use custom with optional aspect-ratio lock to keep source proportions. Format-conversion pages default to the source size.

About This Tool
Convert PNG to WebP for smaller downloads in websites and browser-based 3D viewers. WebP supports efficient compression and transparency, ideal for UI overlays and material maps on the web. Adjust quality to balance size and fidelity. All processing is done locally in your browser.
Tips
- 1WebP with transparency is often 25–35% smaller than PNG
- 2Great for web 3D viewers and glTF-related image workflows
- 3Transparent PNG converts to WebP with alpha preserved

How to Use
1
Import Image File
Drop a PNG, JPEG, WebP, BMP, or KTX2 texture/image file. KTX2 inputs are automatically decoded to PNG for conversion.
2
Configure Conversion Parameters
Choose output format when available (PNG, JPEG, WebP, KTX2), set target dimensions for texture size, and adjust quality. For KTX2, pick ETC1S or UASTC.
3
Convert and Download
Click Convert to process the image or texture. The file downloads automatically in your chosen format — ready for web, design, or 3D pipelines.
Frequently Asked Questions
About this tool
Q
What is WebP and why convert from PNG?
A
WebP is a modern format with strong compression versus PNG. Converting PNG to WebP can cut size by 25–80% while keeping quality and transparency — useful for web pages and online 3D texture delivery.
Q
Is WebP transparency preserved?
A
Yes. WebP supports alpha transparency just like PNG. Transparent areas are preserved in the output.
Q
What's the difference between lossy and lossless WebP?
A
Lossless WebP preserves the exact image data like PNG. Lossy WebP achieves smaller files by discarding some visual information, controlled by the quality slider.
Q
Is WebP widely supported?
A
Yes. WebP is supported by all modern browsers including Chrome, Firefox, Safari, and Edge. It's the recommended format for web images.
Q
Is WebP used in 3D pipelines?
A
Yes, especially for web and runtime delivery where download size matters. Some DCC tools and engines still prefer PNG or KTX2 for authoring and GPU textures — convert as your target pipeline requires.
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.
