Compress a JPG Image…
JPG compression is the highest-ROI optimization you can perform on the web. A poorly optimized site serves images several megabytes large when a few hundred kilobytes would be more than enough, which directly hurts your Google rankings (Core Web Vitals), mobile conversion rate, and perceived quality of experience. Smart JPG compression removes information the human eye can't see anyway: extremely subtle hue variations in flat areas, micro-details in deep shadows, redundancy between neighboring pixels. Our algorithm finds the best size-to-fidelity tradeoff for each image, often resulting in a spectacular size reduction — 70 to 90% for a typical photo — for a difference that's invisible on screen. Even better: processing happens entirely in your browser, so your personal, professional, or confidential photos never leave your device, unlike most online services that upload them to their servers.

Everything that deserves a clear answer.
Will compression blur my photos?+
No. We use 'smart lossy' compression. This means we remove information that the human eye cannot perceive. The image remains sharp on screen.
What is the difference between JPG and JPEG?+
There is none. They are two extensions for the same file format. Our tool handles both in the exact same way.
Are my images sent to a server?+
Absolutely not. Everything happens on your computer (Client-Side). This is the most secure way to compress personal or professional photos.
How many images can I compress?+
As many as you want. The tool is unlimited and free.
