Compress an image to an exact size
To compress an image, drop it here and pick a quality, or type the size your form asks for, like 50 KB or 100 KB. It's free, and the image is never uploaded.

Compressing images, answered
How do I make a photo exactly 50 KB?
Switch to Target size and enter 50 KB. ImgKit tries quality levels until the file lands just under your number, and shows the quality it used.
What if quality alone can't reach my size?
The image is scaled down step by step until it fits, and the new dimensions are shown on the file. If a form also requires exact dimensions, resize to those first.
Will the photo look bad?
Below roughly 20 KB you'll see some softness. Use Compare on any finished file to check it against the original before you download.
Why did a file come back the same size?
Some images are already well compressed. With the Auto format, ImgKit keeps the original rather than hand you a bigger file.
Is there a limit on how many I can do?
No limit, no signup, no watermark. Your device does the work, and several files download together as a ZIP.
Which is better: lowering quality or reducing dimensions?
Quality first, because it keeps the picture the same size on screen. Dimensions are the stronger lever though — halving the width and height removes three quarters of the pixels — so for a tight limit like 20 KB, resize first and compress after.
Does compressing remove the location data?
Yes. The image is re-encoded from its pixels, so EXIF — including GPS — isn't carried over. If you only want to strip metadata and leave the image untouched, use the EXIF remover instead, which edits the file without re-encoding.
Why does the same size look fine on one photo and poor on another?
Detail is expensive to store. A portrait against a plain wall compresses far harder than a photo of foliage, a crowd or fine text, because there's less variation to encode. Busy images need either more kilobytes or fewer pixels.
