    Frequently asked questions

    Does the image format change?

    No: a JPG stays a JPG and a PNG stays a PNG, only the colours are converted to greyscale.

    Are my files uploaded to a server?

    No. Processing happens entirely in your browser, on your device. No file is uploaded or stored. You can check: once the page has loaded, disconnect from the internet and the tool still works.

    Is there a file size or number limit?

    No. Since nothing goes through our servers, there is no quota. The only limit is your device's memory: a computer handles very large files more easily than a phone.

    Is it really free?

    Yes. No sign-up, no watermark added to your documents and no usage limit.
