What is an Image Compressor?
An image compressor reduces the file size of your images without sacrificing visible quality. Smaller images load faster, save bandwidth, and improve your website speed and SEO rankings.

What Compression Ratio Can I Expect?
With the Smart format and Balanced quality, most photos compress by 50-70%. Screenshots and graphics with flat colors often compress even more. The quality slider lets you trade a little detail for much smaller files.
Are My Images Uploaded Anywhere?
No. Every pixel is processed locally in your browser using the Canvas API. Your images never leave your device, so you can safely compress personal or confidential photos.
