    Frequently asked questions

    Is this tool free?

    Yes. There are no limits, watermarks or accounts.

    Are my images uploaded?

    No. Compression happens in your browser using the Canvas API, so files stay on your device.

    Will the image lose quality?

    JPEG is lossy, but at quality 70 to 85 most photos look the same to the eye while shrinking a lot.

    Compressing PNG files

    PNG is lossless, so the main way to shrink it is to reduce dimensions or switch formats. Keep PNG for logos, icons and screenshots with sharp text. For photographs saved as PNG, switching the output to JPEG or WebP usually cuts the size by 70 percent or more.
