Image Compressor – Compress JPG, PNG & WebP Online
Compress JPG, PNG and WebP images in your browser. Choose quality or a target size, optionally resize dimensions, and compare the real before-and-after file size.
Reduce image file size with a quality setting or a target-size goal, and optionally reduce pixel dimensions when that is the most effective way to meet an upload limit.
How it works
Output size depends on source dimensions, image format and compression quality.
Example
Lower JPEG quality usually produces a smaller file, with more visible compression at very low settings.
How to use
- Choose a JPG, PNG or WebP image.
- Select quality mode or enter a target file size.
- Optionally reduce the longest image dimension while preserving aspect ratio.
- Compress the image, compare the measured output and download only after reviewing it.
