Free Online Image Compressor

Make photos smaller for your website, WhatsApp or email. Images are compressed on your own device and never uploaded.

Free, no sign-up. Runs in your browser, so nothing you enter or upload is sent to our server.

How It Works

How to Use the Image Compressor

  1. Drop one or more JPG, PNG or WebP images into the box, or click to choose them.
  2. Pick an output format and move the quality slider. 75–80% is a good balance for websites.
  3. Set a maximum width if the photo is larger than it will ever be shown, for example 1920 px.
  4. Check the new size and savings for each image, then download them one by one or all together.

Why It Matters

Large images are the most common reason a website is slow. A photo straight from a phone is often 3–6 MB, while the same picture on a web page only needs 100–300 KB. Compressing it first makes pages load faster, uses less of your visitors' mobile data and helps your Google rankings.

This compressor re-encodes each image in your browser at the quality you choose. For photos, WebP at 75–80% usually gives the smallest file with no difference you can see. PNG is lossless, so use it for logos and screenshots with sharp edges, and resize large PNGs to cut their size.

FAQ

Image Compressor: Questions

Are my images uploaded to a server?
No. Everything happens inside your browser using your own device. Your images never leave your computer or phone, so the tool is safe for private photos and client files.
What quality should I use for website images?
For photos, 75–80% quality is the usual sweet spot. Files are often 60–80% smaller and the difference is not visible on screen. Go lower only for small thumbnails.
Which format gives the smallest file?
WebP is usually 25–35% smaller than JPG at the same visual quality and works in all modern browsers. Use JPG if a platform does not accept WebP, and PNG for logos that need transparency.
Is there a limit on file size or number of images?
There is no fixed limit. Very large images (over about 40 megapixels) may be slow on older phones because the work is done on your device.
