About This Tool

Convert WebP to JPG/JPEG for maximum compatibility across devices, software, and 3D tools that prefer JPEG base-color maps. JPG uses lossy compression ideal for photos and complex images. JPG does not support transparency. All processing is done locally in your browser.

Tips

  • 1Use JPG for photos and opaque color maps, not for crisp UI elements
  • 2Transparent areas in WebP will render as white in the JPG
  • 3Adjust quality to balance texture pack size against visual fidelity

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.

Lossy compression quality for JPEG and WebP. Higher values yield better quality but larger files.

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:
JPG (JPEG) is the most universal lossy photo format, standardized by the JPEG committee in 1992, offering a good balance between quality and file size, and supported by virtually every device and software. It is ideal for photographs, screenshots, and web images. The downside of JPG is that compression introduces block artifacts and it does not support transparency, causing edges and text to blur. For image-to-3D conversion, JPG suits photographic height maps, but for contour-based conversion, PNG is recommended for clean edges; artifacts at the boundary between dark backgrounds and subject may affect the quality of the generated mesh.

Notes:

  • Maximum supported resolution: 4096×4096 pixels
  • Lossy compression may introduce artifacts on sharp edges

Supported Features:

  • Efficient lossy compression for photos
  • Broad compatibility across all platforms and editing tools
  • 24-bit RGB color support

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

When should I choose JPG over WebP?

A

When you need maximum compatibility: JPG opens in virtually every device, editor, printer, and 3D pipeline, while WebP support is inconsistent in older software. If compatibility is not a concern, WebP is usually the more efficient format.

Q

My WebP was saved losslessly, will the JPG keep that quality?

A

No. JPG always uses lossy compression, so the output is re-encoded and cannot be pixel-identical to a lossless WebP. Use the quality slider to balance fidelity against file size.

Q

Will the JPG output work for printing?

A

Yes. JPG is the standard format for photo printing and sharing, accepted by print services and photo labs. Use a high quality setting (90 or above) to keep the output suitable for print.

Q

Will the file be smaller?

A

At comparable quality settings, JPG files are typically similar in size to WebP. The exact size depends on the image content and the quality setting you choose.

Q

Is JPG suitable for 3D textures?

A

Yes for opaque color or albedo maps where file size matters. Prefer PNG or WebP when you need alpha (opacity, masks) or lossless detail for normal maps.

Q

Will JPG cause banding in smooth gradients?

A

At lower quality settings, JPG can show slight banding or blocking in very smooth gradients. Keeping quality at 85 or higher minimizes this; lossless formats like PNG or WebP avoid it entirely.
