Drop images in and the tool re-encodes each one in your browser — adjust the quality slider, cap the maximum width/height, or set a target size in KB and let it find the right quality automatically. JPG and WebP compress the most; PNG benefits most from resizing or switching format.

Frequently asked questions
Which formats can I compress?
JPG/JPEG, PNG, and WebP. You can also switch the output format (e.g. PNG to WebP) for a much smaller file.
Is Image Compressor free?
Yes — Image Compressor is free with no account, no watermark, and no file-count limit.
Are my files uploaded?
No. The compression runs entirely in your browser with the Canvas API. Your files never leave your device.
Will quality drop?
You control it. A higher quality setting keeps the file closer to the original; a lower setting makes it smaller. Preview the output size before you download.
