How to use this tool
- Select up to 10 images from your device.
- Choose JPG or WebP and a target size in KB, then process the images.
- Compare the original and result, check the actual size, and download each image.
How it works
Reduce JPG, PNG or WebP images to a target file size. Compare the result and download JPG or WebP, processed privately in your browser.
The browser redraws each image and tries several quality levels. If needed, it also reduces the pixel dimensions. A bounded search aims for the requested size; it is not a lossless optimizer. One KB in this tool is 1024 bytes.
What to keep in mind
A target size is not guaranteed. JPG uses a white background for transparent pixels. Large images may be reduced; animations and original metadata are not preserved. Inputs are limited to 20 MB each, 50 MB total, 10 files, 24 megapixels and 8192 pixels per side. Check important details such as small text before use.
Frequently asked questions
Can I compress an image below 100 KB?
Set the target to 100 KB. The tool adjusts quality and, if necessary, dimensions. It shows the actual file size and warns if the target cannot be reached.
Will quality change?
Yes. JPG and WebP encoding can remove fine detail, and smaller dimensions remove pixels. Compare the previews before downloading.
Can I keep a transparent background?
Choose WebP. JPG cannot store transparency and uses white in its place.
Are my photos uploaded?
No. Images are read and processed in your browser. Only an explicit download saves the result to your device.
