Files never leave your device
Make JPG, PNG, WebP and AVIF images smaller without changing their format. Pick a quality level or a target file size and compare the result with the original before downloading.
How it works
- Choose images or drag them onto the page — several at once is fine.
- Set the quality or the target size in KB and click Compress.
- Compare before and after, then download the files one by one or all together in a ZIP archive.
Frequently asked questions
How much smaller will my images get?
It depends on the image: high-quality photos often shrink by half or more, while files that are already optimized change less.
Does compression change the size in pixels?
No. Width and height stay the same; to make an image smaller in pixels, use the Resize images tool.
Is it free?
Yes. All tools are free, with no sign-up and no watermarks.
Are my files uploaded to a server?
No. Everything runs in your browser, so your files never leave your device.
