Frequently asked questions
Will compression make my image look worse?
A little, at low settings — that is the trade-off for a smaller file. Quality 80 keeps photos looking sharp while cutting the size dramatically. For logos or graphics with text, stay at 90 or above.
Which formats can I compress?
JPG, PNG and WebP. One thing to know: PNG is a lossless format, so the quality slider has the biggest effect on JPG and WebP output.
Is my image uploaded to a server?
No. The compression runs entirely in your browser using your own device’s processing power. Nothing is uploaded, stored or seen by anyone else.
What max width should I pick?
For full-screen photos, 1920 px is plenty. For blog post images, 1280 px or 800 px loads faster and still looks crisp on every screen.
