Frequently asked questions
How much can I shrink an image without it looking bad?
It depends on the source, but most photos hold up well down to 60-70% quality. Below that, compression artifacts (blockiness, colour banding) become noticeable, especially around sharp edges and text.
Does this work for PNG as well as JPG?
Yes — both are supported, though PNG (lossless) generally compresses less than JPG since it's designed not to lose quality.
Is Compress Image free to use?
Yes — Compress Image is completely free with no limits, no watermarks and no sign-up. It runs in your browser, so there is nothing to pay for.
Are my files uploaded or stored anywhere?
No. This tool does all its work locally in your browser using your own device's power. Your files never leave your device and we never see them.
Do I need to install anything or create an account?
No installation and no account needed. Compress Image works on any modern browser — Windows, Mac, Linux, Android and iPhone.
How do I use Compress Image?
Open the tool, add your file (or paste your content), adjust any options, then press “Compress image”. Your result is ready to download in seconds.
