About Reduce Image Resolution
Reducing image resolution means lowering the pixel count of a photo, for example from 4000x3000 down to 1920x1080. Set the width and height you need below, and the tool keeps the aspect ratio so your photo does not stretch. Upload up to 10 photos at once and download the resized files in seconds.
Image resolution is the number of pixels a photo contains, written as width x height, such as 1920x1080. More pixels means more color data, so a higher-resolution photo carries more detail and a bigger file. Cut the pixel count and both the detail and the file size drop with it.
Lowering resolution and compressing a file solve different problems. Resolution reduction removes pixels, so a 4000x3000 photo resized to 1920x1080 has fewer dots to store and often drops from 8MB to near 2MB. Compression keeps every pixel in place and re-encodes the color data at lower quality instead, which is how that same photo can shrink to 500KB without its dimensions changing. Pick resolution for an exact pixel request, and compression for a KB limit. Need just a KB number? Our image size reducer targets an exact kilobyte count instead.
Already know the exact pixel number your form wants? Our resize image to exact pixels tool sets width and height the same way.
Your photo is deleted from our server automatically. This tool resizes images on our end, so your file travels over an encrypted HTTPS connection first. We process it, hand back your download, and remove the original from our server within 20 minutes. There is nothing left for you to delete yourself.
Does reducing resolution reduce quality? Yes. Lowering resolution removes pixels permanently, so fine detail is gone for good. Keep a copy of your original file if you need the full-size version later.
