WebP is widely used for images on modern websites, but the format alone does not determine whether a particular file is small enough for its purpose. A photograph may have more pixels than a page needs, or its saved quality may be higher than necessary for the size at which it will be displayed. The WebP Compressor helps you adjust output quality, resize the image width when needed, and see how the result compares with the original.
Rather than applying one setting to every image, you can work from the intended use. A large hero photograph, a small article thumbnail, and a compact illustration may need different combinations of dimensions and quality. The preview and file-size summary help you assess those choices before saving the output.
The editor provides a quality slider from 10% to 100%, with 80% as the starting value. Changing this setting affects how the browser encodes the WebP output. Lower values can reduce file size, although they may also make fine details or subtle color transitions less faithful to the source.
The lowest value is not automatically the best choice. A photograph used at a large size may need more detail than a small thumbnail. If an image contains fine textures, lettering, or product details, inspect those areas as you test different quality values. The best setting is the one that meets your size needs while keeping the image suitable for its intended display.
The target-width field accepts values from 50 to 8,000 pixels. Enter 0 to keep the original width, or choose another value to scale the image while preserving its aspect ratio.
Resizing can make a meaningful difference when the source is larger than the layout requires. For example, a photo intended to appear in a narrow content column may not need its full original width. The editor also allows upscaling, but increasing dimensions does not recover missing detail and can produce a larger file. For optimization, match the dimensions to the intended display area whenever possible.
After you change the quality or width, the summary shows the new file size and the percentage saved or added compared with the original. These figures give you a practical way to compare the outcome instead of guessing based on the slider position alone.
If the dimensions remain unchanged and the generated file is not smaller, the tool can keep the original rather than replace it with a larger version. If you resize the image, however, the result is evaluated based on the generated file. A good result should have suitable dimensions, acceptable visual quality, and a file size that meets your needs.
If you want to keep the WebP format, adjusting quality and dimensions is a sensible starting point. If you need to switch to another format, use the Image Format Converter. For a wider selection of supported image types, the Image Compressor may be more convenient. When dimensions are the main concern, the Image Resizer offers a more direct route.
Does a lower quality setting always make the file smaller?
Not in every case. The final size depends on the image and the encoding result. The tool checks the generated size, and when the dimensions are unchanged it can retain the original if the output is not smaller.
What quality setting should I use?
The tool starts at 80% and allows values from 10% to 100%. The right setting depends on the image, the intended display size, and how much fine detail needs to remain visible. Compare the preview rather than applying the same value to every image.
Can I resize a WebP image while compressing it?
Yes. You can specify a target width between 50 and 8,000 pixels while preserving the aspect ratio, or enter 0 to retain the original width.
Why is the output sometimes larger?
Some encoding settings or dimension changes can result in a larger file. When the dimensions remain unchanged and the new file is not smaller, the tool can keep the original. If you have resized the image, check the actual new dimensions and file size to decide whether the result is suitable.
