FAQ

Does this reduce image dimensions too?

No — only compression quality changes. Width and height stay the same. Use Image Resizer for dimensions.

Does PNG actually get smaller?

PNGs are re-encoded as JPEG for maximum size reduction, since PNG's lossless format can't shrink much through quality alone. If you need to keep transparency, this isn't the right tool.

How do I compress an image to a specific size, like under 200KB?

There's no target-size input — instead, lower the quality slider and check the resulting file size shown after compression, adjusting until it's under your target. Most photos reach under 200KB comfortably around 50–70% quality.

Does this work on Mac, Windows, or my phone?

Yes — it runs in any modern browser on Mac, Windows, Chromebook, iPhone, or Android. No app or software to install.
