Compress Image Online
Big images slow down websites, fill up your storage, and fail to send in emails. This tool shrinks JPG, PNG, and WebP files so they are much smaller, and in most cases you will not see any difference in quality.
Drop your image in, pick a level, and download the lighter version. It takes a few seconds. If you run a website, smaller images mean faster pages, which is good for visitors and good for search results too.

Frequently Asked Questions
Does compressing an image reduce its quality?
A little, but usually not in a way you can see. The tool removes extra data that your eyes do not notice. If you pick a very high compression level, the image can start to look soft or blocky.
How much smaller will my image get?
It depends on the image. Photos often shrink a lot, sometimes by more than half. Images that are already compressed will shrink less.
What is the best format for a small file size?
WebP usually gives the smallest file for the same quality. JPG is good for photos and PNG is good for graphics with sharp edges or a clear background.
Is it safe to compress my photos here?
Yes. The work happens in your browser, so your photos are not sent to a server.
Will the image size in pixels change?
No. Compression lowers the file size, not the width and height. If you also want fewer pixels, use the Resize Image tool.
Is this image compressor free?
Yes, it is free to use and there is no watermark.
Lossy vs Lossless Compression
There are two ways to make an image smaller. Lossy compression removes small details that most people cannot see. This gives a big drop in size. JPG and WebP use this method.
Lossless compression keeps every pixel the same and only rearranges the data to save space. The file gets smaller, but not by as much. PNG uses this method.
For photos, lossy compression is almost always the better choice. For logos, icons, and screenshots with text, keep the quality high so the edges stay sharp. A good rule is to compress until the file is small, then zoom in and check that it still looks clean.
Who Uses an Image Compressor?
- Website owners speed up pages by using lighter images.
- Online store sellers upload many product photos without slowing down the shop.
- Bloggers keep posts fast even with lots of pictures.
- Students and office workers fit photos under the size limit on forms and portals.
- Anyone sending email who needs attachments to go through.
