How to use Compress image
- Add the image you want to make smaller.
- Choose a quality level, or type a target size such as 100 KB.
- Press the compress button and compare the before and after previews.
- Download the smaller file once you are happy with how it looks.
Why use this tool
Image compression stores the same picture in fewer bytes. Many websites and government forms limit uploads to a few hundred kilobytes, and smaller images load faster and are easier to email. A good compressor lowers the size a lot while keeping the picture looking almost identical to the eye.
Tips for best results
- For photos, a quality of around 70 to 85 percent is usually the sweet spot.
- If a form says the file must be under a certain size, use the target size option and let the tool find the quality for you.
- Compress the original file, not one that has already been compressed several times.
Frequently asked questions
Why is my compressed file still large?
Very large dimensions are the usual cause. Resize the picture to the size you actually need first, then compress it.
Which format compresses best?
JPG and WebP are best for photos. PNG is lossless, so it stays larger, but it is better for screenshots and graphics with text.
Does it work on my phone?
Yes. Everything runs in your mobile browser and nothing is uploaded.
