About WebP compression

Large WebP file sizes usually result from excessively high quality settings during export, additional metadata overhead such as EXIF and XMP, and suboptimal encoder implementations in export tools.

This tool adjusts encoder quantization based on the Sharp engine to reduce file size with minimal perceptible quality change. Optimized files are approximately 60% to 80% the size of unoptimized files at the same visual quality. Higher quality settings preserve more detail, and multiple repeated compressions cause generational quality loss.

This compression is suitable for performance budget control in web development, and meets email attachment size limits. For already highly compressed WebP source files, compression may result in increased file size rather than reduction.

FAQ about Compress WebP

Will compression affect image quality

Minor perceptible changes will occur. This tool prioritizes preserving core visual details during compression, and reduces size by adjusting quantization to sacrifice information that is not easily detectable by the human eye.

How much size can compression reduce

Unoptimized source files typically achieve a 20% to 40% size reduction. Already highly compressed WebP source files will not see significant size reduction from compression, and may even increase in size.

What is the single file size limit

The maximum single file upload size for this tool is 50MB. Only one file can be processed per conversion. The service is free, output files have no watermarks, and no account registration is required.

Will uploaded files be stored

Your files are not stored. Files are uploaded via HTTPS to the server for conversion, and the server immediately deletes both source and output files after conversion completes. No files are stored.
