The tool this page covers is ImgNovo, a browser-based image compressor. Put simply, it compresses JPG, PNG and WebP images, converts between those formats and downloads the results as a zip, all without uploading them, and the way it does so is this: it decodes each image in the browser, re-encodes it at the quality level you choose and reports the size before and after, so the compression runs on your own machine and the file never leaves it. Everything stated here applies to that tool and the values it handles, and to nothing else.
In day-to-day use the tool works only from the images you drag in, and it is usually opened for things like shrinking photos before attaching them to an email. None of that reaches us, so none of it can be stored.
General information only
Nothing on imgnovo.com is professional advice. What ImgNovo produces is an estimate of a calculation rather than a measured fact, published for general information and education.
General-purpose tools
The tools here return a fast, general answer. Where a ImgNovo result carries a consequence — something that gets built from, filed, or paid — check it independently first.
No warranty
For ImgNovo specifically, the operative assumption is that your input fits the case the tool is built for. It decodes each image in the browser, re-encodes it at the quality level you choose and reports the size before and after, so the compression runs on your own machine and the file never leaves it. Outside that — and wherever rounding, unit handling or browser behavior intrudes — the Site offers no warranty of any kind; we take care over the method, but the result is what it is.
Third-party links
External links are offered for reference only. We neither control nor vouch for outside content or its accuracy.
Adverts and sponsorship
The Site is funded by advertising. No advertiser has any say over a result, and no ad should be read as an endorsement.
Checking before you act
Make sure any result suits your own situation before you act on it. If you think something is wrong, the contact page is the quickest way to let us know.
