How to Compress Images for the Web

Resize first when the image is much larger than its display area

Compression changes how the image is encoded, while resizing changes the number of pixels. If a photo will only display at a modest size, reducing oversized dimensions first often makes a larger difference than lowering quality alone.

• Use the Image Resizer for a sensible maximum width before compression.
• Avoid enlarging a small source image; resizing up cannot create missing detail.
• Keep the aspect ratio locked unless you intentionally need a different shape.

Choose quality by looking at the image, not a magic percentage

There is no single quality setting that is right for every image. Begin with a balanced setting, inspect the result, and lower it gradually only if you need a smaller file. Product details, faces, gradients, and text usually deserve a closer check.

Use the before-and-after file size as your decision point

The compressor shows the original and resulting size after processing. That real result is more useful than promising a fixed percentage because savings depend on the original format, subject, dimensions, and chosen quality.

1. Add JPG, PNG, or WebP files to the Image Compressor.
2. Adjust quality if needed and process the files locally in your browser.
3. Review the resulting size and image appearance before you publish it.
