About This Tool

Convert WebP images to PNG for maximum compatibility across design tools and 3D pipelines. PNG is lossless and supports transparency, making it ideal for albedo, mask, and UI textures as well as general editing. Everything is processed locally in your browser.

Tips

  • 1PNG is a lossless format, so converting from WebP causes no quality loss.
  • 2Keep alpha maps as PNG so transparency and mask data stay intact for 3D materials.
  • 3Export to PNG before importing into Blender, Unity, or other DCC tools that lack WebP support.
  • 4Expect a larger file than the source WebP, so plan PNG exports for final assets rather than every draft.

About Configuration Options

Output Dimensions

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.

Lock aspect ratio

Defaulton

When enabled in custom size mode, changing width or height automatically scales the other side to match the source image proportions. Disable to set width and height independently.

Format Information

Input format

Extension:

Full Name:
WebP (Google)
Type:
Image
Format:
WebP
Tools:
Photoshop、GIMP、Krita、Paint.NET
Open With:
Image Editor、Windows Photos、Preview (Mac)
Description:
WebP is a modern image format developed by Google, supporting both lossy and lossless compression as well as an alpha channel. Under the same visual quality, file sizes are typically 25-35% smaller than JPEG or PNG, making it a mainstream choice for web performance optimization. WebP browser compatibility is now very mature, but it may still not be supported in older systems and some professional software. When used as a 3D texture or input for image-to-3D conversion, its performance is comparable to PNG; just be aware of compression artifacts in lossy mode.

Notes:

  • Maximum supported resolution: 4096×4096 pixels
  • Transparent backgrounds are supported in lossless mode

Supported Features:

  • Lossy and lossless compression modes
  • Alpha channel transparency in lossless mode
  • Smaller file sizes than legacy formats

Description:
PNG is a lossless raster format with 8-bit alpha transparency, offering sharp edges and no artifacts. It is preferred for converting silhouettes to 3D models, avoiding color banding and producing cleaner meshes than JPEG. The trade-off: larger file sizes than JPEG, no CMYK support. For 3D conversion: use 16-bit grayscale for height maps (up to 4096×4096); transparent backgrounds are auto-detected, so manual masking is unnecessary.

Notes:

  • Maximum supported resolution: 4096×4096 pixels
  • Transparent backgrounds are automatically detected and handled

Supported Features:

  • Lossless compression preserves image quality
  • Alpha channel transparency for precise contour extraction
  • Wide color support (24-bit RGB + 8-bit alpha)

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 texture dimensions, 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

View all FAQs
Q

Why would I convert WebP back to PNG?

A

PNG has wider compatibility across design tools, DCC applications, and many 3D engines that expect PNG texture maps. If a pipeline or older app does not support WebP, converting to PNG keeps the asset usable.

Q

Will I lose any quality?

A

No. The conversion is lossless, so every pixel and the alpha channel are preserved exactly.

Q

Will the PNG file be larger?

A

Usually yes. PNG relies on lossless compression while WebP can use lossy compression, so the PNG version tends to be bigger than the source WebP.

Q

Can I use PNG for 3D model textures?

A

Yes. PNG is a standard format for albedo, normal, roughness, and other texture maps. Convert WebP textures to PNG when your engine, exporter, or DCC tool requires PNG.

Q

What happens if I convert an animated WebP file?

A

Animated WebP cannot be converted to PNG as animation. Only the first frame is extracted and saved as a static PNG. For animation, use GIF or APNG instead.

Q

When is it worth converting WebP to PNG?

A

Convert when a tool or engine does not accept WebP, when the image has transparency or needs further editing, or when you want a lossless intermediate file. Plain photos without alpha rarely benefit from PNG.
