How much can I reduce an image file size?

Typical results are 40–80% size reduction depending on the original image and quality setting. JPG images with a quality of 80% often look nearly identical to the original.

Will compressed images look different?

At quality settings of 75–85%, compressed images look nearly identical to the original. Below 60%, some artifacts may become visible on close inspection.

Does compressing change the image dimensions?

No. The compressor only reduces the file size. The pixel dimensions (width and height) remain the same.

Which image format compresses best?

WebP typically achieves the best compression at a given quality level, followed by JPG. PNG compression is lossless and results in larger files.
