Tool usage guide
Optimize your WebP images with precision using our quality adjustment tool, designed to help you balance file size and visual fidelity through lossless, lossy, and near-lossless compression settings.
Background
A high-resolution hero image in WebP format is slowing down page load times on a landing page.
Problem
The file size is too large for optimal web performance.
How to use
Upload the image and set the quality to 75 with a compression effort of 6 to maximize size reduction.
quality: 75, effort: 6Outcome
The image file size is significantly reduced while maintaining visual clarity for site visitors.
Background
Need to store a collection of WebP assets without any loss of detail.
Problem
Standard compression settings might introduce artifacts in complex illustrations.
How to use
Enable the 'Lossless Compression' checkbox to ensure the output is identical to the source.
lossless: trueLossless compression reduces file size without losing any image data, while lossy compression discards some data to achieve significantly smaller file sizes.
Higher effort values result in better compression and smaller files, but the processing time required to generate the image will increase.
Yes, you can use the Alpha Channel Quality slider to specifically control the quality of the transparency layer in your WebP file.
Near-lossless compression provides a balance between high visual fidelity and efficient compression, with quality automatically set to a minimum of 85.
You can upload WebP files up to 50MB for processing.
Outcome
A perfectly preserved image file with no quality loss, ready for archival.
