Image Compressor

Shrink JPG, PNG, or WebP file size with an adjustable quality slider.

Your files stay on your device — nothing is uploaded

Drop an image here, or click to browse

Your file is processed locally and never uploaded.

Big photo files slow down websites, blow past email attachment limits, and eat up storage. This compressor re-encodes a JPG or WebP at whatever quality level you choose, showing the before/after file size live, so you can find the sweet spot between size and quality yourself — entirely in your browser.

How to use the image compressor tool

  1. 1

    Upload a photo

    Drop in a JPG, PNG, or WebP image.

  2. 2

    Adjust the quality slider

    Drag it lower to shrink the file further — the preview and file size update live.

  3. 3

    Download

    Save the compressed image once you're happy with the size/quality trade-off.

Frequently asked questions
