How this image compressor works

Your image is loaded into your browser and re-encoded using the quality and format you choose. Lowering the quality slider reduces file size by allowing more compression artifacts; switching to WebP often gives a smaller file than JPEG at the same visual quality. PNG is lossless, so its size depends mainly on the image content rather than the quality slider.

Tips for choosing settings

Will compressing reduce image dimensions?

No — this tool keeps the original width and height and only changes how the pixel data is encoded. If you also need to resize the image, do that first in an image editor, then compress the resized version here.

Do you store or see my image?

No. The image is processed entirely in your browser using the HTML canvas API and is never uploaded anywhere.
