How it Works
The Bulk Image Compressor uses modern browser canvas and rendering APIs to process your graphics. When you load an image, it is drawn into an in-memory canvas element. The tool then applies mathematical transformations to compress, resize, flip, or rotate the pixels, and outputs the result in your requested format—all happening in real-time right on your computer.
S_{new}
Compressed file size of output images
S_{old}
Original file size of input images
c
Target quality compression ratio (0.0 to 1.0)
Image Compression Formula
S_{new} = S_{old} \times c
- S_{new}: Compressed file size of output images
- S_{old}: Original file size of input images
- c: Target quality compression ratio (0.0 to 1.0)
