How to use Image Compressor

Why use Image Compressor
- Faster websites: smaller images load faster, which helps visitors and search engines.
- Easier sharing: many email services, forms and apps limit file size.
- Saves space on your phone and computer.
- Private: your photo stays on your device.
How image compression works
JPG and WebP use lossy compression. They store a slightly simplified version of the picture, and a lower quality setting simplifies it more. That is why the file gets smaller. At moderate settings the change is hard to notice, and the preview lets you check before you download.
PNG uses lossless compression, which keeps every pixel but usually makes larger files for photos. That is why this tool saves a JPG as a JPG, and saves other images, such as a PNG, as a WebP.
Need an exact file size?
If a form asks for a photo under a certain size, use one of our target-size tools: Compress Image to 50KB, Compress Image to 100KB or Compress Image to 200KB. They find the best quality that still fits under the limit for you.
Tips for best results
- Start around 80% quality and lower it until you can see a difference in the preview.
- Photos usually compress better than screenshots or graphics with sharp text.
- Making the picture smaller in pixels also reduces file size. Try the Image Resizer first for very large photos.
- Keep your original file in case you need the full quality later.
Frequently asked questions
Will compression reduce the quality of my image?
A little, depending on the quality you choose. At moderate settings the difference is usually hard to see, and the preview lets you check before you download.
Why did my file get bigger?
Files that are already well optimized can grow slightly when they are saved again. If that happens, try a lower quality setting or keep your original.
What format will my compressed image be?
A JPG stays a JPG. Other images, such as PNG files, are saved as WebP. If you need a different format, use one of the converters.
Why does it say my browser can't create that format?
Some browsers, especially older versions of Safari, cannot create WebP files. Try a current version of Chrome, Edge or Firefox, or compress a JPG instead.
Is this tool free?
Yes. It is free to use and needs no account or registration.
Are my images uploaded to a server?
No. Processing happens inside your browser, so your image never leaves your device.
What image formats are supported?
JPG, PNG and WebP are supported, up to 25 MB. Other formats work if your browser can open them.
Can I use this tool on mobile?
Yes. It works in modern mobile browsers, though very large files may be slow on older phones.
