Frequently Asked Questions
How do I reduce image size to 50kb?
Upload your image, then drag the "Quality" slider down until the "Compressed Size" indicator shows ~50kb. If the file is still too big, use the "Resize" slider to make the image dimensions smaller.
Does reducing size ruin quality?
Not necessarily. Reducing quality to 70-80% is usually invisible to the human eye but can cut file size by 50%. However, going below 30% might make the image look pixelated.
Can I convert PNG to JPG?
Yes! If you upload a PNG but want a smaller file, the browser might automatically convert it to a heavy compression format if you choose a low quality setting, or you can screenshot the result.
