- Target KB Feature: Need an image exactly under 50KB or 100KB for an official form? Just type your target size, and our smart algorithm will hit it.
- Next-Gen Formats: Seamlessly convert legacy JPG and PNG files into modern WebP or AVIF formats for maximum SEO and performance benefits.
- Batch Processing: Drag and drop up to 20 images at once. Compress them simultaneously and download them in a neat ZIP file.
How to Compress an Image Without Losing Quality?
Our tool utilizes a smart binary search algorithm for compression. When you upload an image, you can use the interactive Before/After slider to see the results in real-time. By gently adjusting the quality slider, or stripping unnecessary metadata (EXIF/Location data), you can reduce a photo's file size by up to 80% while keeping it visually indistinguishable from the original HD version.
