Compress image
Reduce image file size without uploading anything. Set a quality level or a target size in KB and download the result.
How compression works
The image is re-encoded at a lower quality. With a target size, the tool tries several quality levels and, if needed, scales the image down slightly.
PNG files
PNG is lossless, so quality settings do not shrink it. Choose JPG or WebP for photos to get much smaller files.
Compress image FAQ
How does the image compressor work?
It re-encodes your image as JPG or WebP with a lower quality and, if needed, smaller dimensions. You can set a quality level or a target size in KB and the tool searches for the best fit.
Can I compress to an exact size like 100 KB?
Yes. Enter a target size and the tool tries quality levels, then shrinks the dimensions slightly if the quality alone is not enough.
Are my images uploaded?
No. Compression happens in your browser and nothing is sent to a server.
Why did my PNG become a JPG?
PNG is lossless and cannot be compressed by lowering quality. Choosing JPG or WebP gives much smaller files for photos.
Will small file sizes hurt my site?
Smaller images load faster, which helps user experience and SEO. Keep an eye on quality for important images and compare the preview.
