How to compress an image
Choose one or more images, pick a quality level and press Compress images. Download files individually or grab the whole batch as one ZIP.
Compress Image
Reduce image file size quickly. Processing happens locally in your browser, so your images do not need to be uploaded to our server.

JPEG, PNG and WebP supported
First adjust quality, then reduce resolution if necessary. The target size is best effort.
JPG and WebP use quality-based compression. PNG uses local color quantization for real size reduction. If the result would be larger than the original, the original file is kept instead.

No server upload
The current compressor works with browser canvas APIs. Your image pixels stay on your device while the tool runs.
Target a file size
Enter a target such as 200 KB to let the tool search for a smaller result automatically. Leave it blank to use the quality control only.
