Large images slow down websites, fill up storage and are a pain to email. The good news: you can dramatically shrink image file sizes while keeping them looking great. Here is how.
Why image size matters
Images are usually the heaviest part of a web page. Smaller images mean faster loading, better search rankings and happier visitors. For sharing, smaller files upload quicker and slip under email attachment limits.
How to compress an image
- Open the free Image Compressor.
- Choose your JPG or PNG image.
- Drag the quality slider to balance size and clarity.
- Download the compressed image.
If you also need to change the dimensions, the Image Resizer lets you set an exact width and height while keeping the proportions correct.
Compression tips
For photos, a quality setting around 70–80% usually removes most of the file size with no visible loss. For graphics with sharp edges or text, keep quality higher. Always preview before downloading. Need the image as code for a website? Try the Image to Base64 tool.
Frequently asked questions
Will compressing reduce quality? A small amount of data is removed, but at sensible settings the difference is invisible to the eye while the file gets much smaller.
Are my photos uploaded? No. Compression happens entirely in your browser, so your images stay private.
