Convert PNG to WEBP via Java
Transform PNG into WEBP using native Java APIs without needing any image editor or 3rd-party libraries.
How to Convert PNG to WEBP Using Java
Converting file formats may seem like a routine task encountered by graphic designers. Yet, underestimating its significance would be a mistake. The evaluation of your work might depend on how swiftly and effectively you tackle this task. Typically, original images need conversion into formats better suited for printing or online publication. If the original image originates from a graphic editor, it might be in vector format. In this scenario, it must be rasterized and converted to a raster format for publishing purposes. You have the choice to save the image in an uncompressed format for optimal quality or convert it to a lossless compressed format to reduce file size. In certain contexts, like web publishing, you can opt for lossy compressed formats. Specially designed algorithms for image data compression permit a significant reduction in file size while preserving acceptable image quality. This facilitates fast image file downloads from the internet. In order to convert PNG to WEBP, we’ll use Aspose.Imaging for Java API which is a feature-rich, powerful and easy to use image manipulation and conversion API for Java platform. You can download its latest version directly from Maven and install it within your Maven-based project by adding the following configurations to the pom.xml.
<repository> <id>AsposeJavaAPI</id> <name>Aspose Java API</name> <url>https://repository.aspose.com/repo/</url> </repository>
<dependency> <groupId>com.aspose</groupId> <artifactId>aspose-imaging</artifactId> <version>version of aspose-imaging API</version> <classifier>jdk16</classifier> </dependency>
Steps to Convert PNG to WEBP via Java
Developers can easily load & convert PNG files to WEBP in just a few lines of code.
- Load PNG file with Image.load method
- Create & set the instance of required subclass of ImageOptionsBase (e.g. BmpOptions, PngOptions, etc.)
- Call the Image.save method
- Pass file path with WEBP extension & object of ImageOptionsBase class
Before running the conversion example code, make sure that you have the following prerequisites:
- JDK 1.6 or higher is installed.

PNG What is PNG File Format
PNG, Portable Network Graphics, refers to a type of raster image file format that use loseless compression. This file format was created as a replacement of Graphics Interchange Format (GIF) and has no copyright limitations. However, PNG file format does not support animations. PNG file format supports loseless image compression that makes it popular among its users. With the passage of time, PNG has evolved as one of the mostly used image file format. Almost all Operating Systems have support for opening PNG files. For example, Microsoft Windows viewer has the capability to open PNG files as the OS has by default the support available as part of installation.Read More | PNG
WEBP What is WEBP File Format
WebP, introduced by Google, is a modern raster web image file format that is based on lossless and lossy compression. It provides same image quality while considerably reducing the image size. Since most of the web pages use images as effective representation of data, the use of WebP images in web pages results in faster loading of web pages. As per Google, WebP lossless images are 26% smaller in size compared to PNGs, while WebP lossy images are 25-34% smaller than comparable JPEG images. Images are compared based on the Structural Similarity (SSIM) index between WebP and other image file formats. WebP is a sister project of WebM multimedia container format.Read More | WEBP
