Supports JPG, PNG, WebP, AVIF. 100% Browser-based processing, absolutely secure.
Compress JPG, PNG, WebP, and AVIF images to around 50KB in your browser. Set a target size, preview results, and download optimized files.
50KB upload workflow
- The compressor opens in target size mode with 50KB selected.
- Use JPG, WebP, or AVIF output for best chance of meeting strict 50KB limits.
- Reduce max width and height if a very large photo cannot reach the target cleanly.
Specific Target Size
Precise control. Enter your desired KB size (e.g., 50KB), and the algorithm automatically adjusts quality to match.
Batch Processing
Drag and drop dozens of images at once. Once processed, download all images as a single ZIP archive.
AVIF / WebP
Export next-gen formats. AVIF reduces size by 50%-80% compared to JPG at the same quality.
Private by design — images are processed locally in your browser whenever the tool supports client-side processing, so your files do not leave your device.
