Why compress WEBP images?
WEBP is already a compact format, but images from phones and design tools can still weigh a few megabytes. This free compressor re-encodes your WEBP with a simple quality slider, so you can trim the file until it loads instantly — with a live preview of exactly what you will get.
Smaller WEBP files mean faster websites, quicker uploads and less storage. Lowering the quality value by 10–20% is usually invisible to the eye while cutting the file size dramatically.
Your file is processed on your device and never uploaded. Try Compress to 100KB or Compress to 50KB.

Frequently Asked Questions
How does image compression work?
Compression makes a file smaller by removing data the eye barely notices. JPG and WEBP use lossy compression that discards fine detail in exchange for much smaller files; PNG is lossless, so it keeps everything and stays larger.
What is the best format for a small file size?
For photos, JPG gives the best quality per kilobyte. WEBP is even smaller and supported by every modern browser. PNG is only efficient for graphics with flat colors or transparency.
What is a WEBP image?
WEBP is Google's modern image format. It produces noticeably smaller files than JPG at the same quality, which makes websites load faster. It is supported by all modern browsers.
Why compress a WEBP?
Even WEBP files from phones and design tools can be a few MB. Compressing makes them load faster, upload quicker and take less storage.
Will I lose quality?
WEBP uses smart compression, so lowering the quality setting usually still looks great. The preview lets you see exactly what you get before downloading.
Is WEBP supported everywhere?
Modern Chrome, Edge, Firefox and Safari all support WEBP. If you need maximum compatibility, convert to JPG instead.
