Image Compressor
Compress JPEG, PNG and WebP images into JPEG or WebP with adjustable quality, file-size comparison and local processing.
Choose your image
Select a PNG, JPEG, or WebP file. You’ll see the original and edited image here.
Adjust the image
Set the size, format, or other options you need.
How to use Image Compressor
- Choose a supported image; its dimensions remain unchanged.
- Select WebP or JPEG and adjust quality from 1 to 100.
- Compare the before and after byte counts, inspect the preview, and download the result.
Reduce transfer size with an explicit quality setting
This tool re-encodes a still image at its original dimensions. WebP and JPEG use lossy compression here, so compare fine detail, gradients and text before publishing. The quality number is an encoder hint, not a percentage of preserved visual information. Results vary with the image and browser encoder.
When compression makes a file larger
Already optimized images can grow after re-encoding. The result reports actual byte sizes and warns when no saving occurred. Lower the quality or resize a very large source instead. JPEG uses a white background for transparent pixels; choose WebP to keep transparency. Animated images and source metadata are not preserved.
Can it guarantee a particular KB target?
No. This tool exposes encoder quality and reports actual sizes. Exact file size depends on image content, dimensions and browser encoding.
Is input uploaded?
Processing takes place in your browser. This tool does not send your input or selected files to a conversion API.
