Got Questions?

Here is everything you need to know about bulk compression.

Because processing happens directly in your browser using local RAM, we recommend compressing batches of up to 50 images at a time (or less if the original files are extremely large, like 10MB+ each) to prevent your browser from freezing.
You can choose between WebP (best for web optimization), JPEG (best for universal compatibility), PNG (for lossless/transparency), and AVIF (next-gen ultra-high compression).
Absolutely. The entire conversion process utilizes HTML5 canvas technology to process the images directly inside your web browser. Your images are never uploaded to a server, making this tool 100% private and secure.
Yes, WebP is universally supported across all modern web browsers, including Chrome, Safari, Firefox, Edge, and mobile browsers. It has become the gold standard for web image optimization.
