Frequently asked questions

How do I compress an image?

Choose a JPG, PNG or WebP image, drag the quality slider until the size and look are right, then click Download. You see the original and compressed size live as you adjust.

How do I reduce the size of a photo to a specific KB?

Lower the quality slider and watch the compressed size update in real time. Stop when it reaches your target, for example under 100 KB or 1 MB, then download.

Which formats can I compress, JPG, PNG or WebP?

All three. You can compress JPG/JPEG, PNG and WebP, and optionally re-encode to WebP for the smallest size at the same visual quality.

Will compressing reduce image quality?

Slightly, depending on the slider. Around 70 to 80% quality usually looks identical to the original while being much smaller, ideal for websites and email.

Are my images uploaded to a server?

No. Everything happens in your browser, so your images never leave your device, safe and private.

Is the image compressor free?

Yes, free with no sign-up and no watermark.
