Questions and answers

Compress Image FAQ

Can I compress an image to a specific size in KB or MB?

Yes. Choose Target size, move the slider or enter an exact value, then select KB or MB. ResizeImg aims for that maximum while preserving as much quality as practical.

Does image compression reduce quality?

Lossy JPG and WebP compression can remove some detail. Start near 82% and lower it gradually until the file is small enough while still looking clean.

Are images uploaded to a server?

No. ResizeImg performs the compression in your browser, so your selected image stays on your device.
