Free Online JPG Compressor Tool

JPG compression reduces file size by removing redundant image data and using lossy compression algorithms. Our tool uses the HTML5 Canvas API to re-encode your image at your specified quality level, reducing file size while preserving visual quality as much as possible.

For web use, we recommend a quality setting between 70-85%. This provides an excellent balance between file size and visual quality. At 80% quality, most images are visually indistinguishable from the original while being significantly smaller in file size.
