Compression Results
Init Compressor is an online tool that helps you compress images quickly and in bulk — significantly reducing file size while maintaining the best possible image quality. Images are processed server-side using a high-performance image library with full support for WebP, PNG, JPEG, and AVIF.
Introduction
With Init Compressor, you can easily compress product photos, screenshots, thumbnails, or any type of image to optimize file size before uploading to websites, social media, or cloud storage.
The tool uses the high-speed image processing library libvips (via Sharp), allowing flexible compression settings while maintaining the best balance between image quality and file size.
You only need to:
- Upload images from your device (up to 10 files) or paste image URLs
- Select an output format or keep the original format
- Choose your preferred compression quality

Results appear instantly with compressed image previews, before/after file sizes, percentage savings, and individual download buttons.
