How to Use Image Compressor — Step-by-Step Guide

Step-by-step instructions

When is this useful?

Useful when a photo is too large to upload, a website image is slowing a page down, or you need a smaller copy for sharing.

Select a JPG, PNG or WebP image. Start with the original file when possible so you always have a clean copy to return to.

Look at the image before compression and note its dimensions and visual details, especially small text or fine edges.

Use the available compression control to balance file size and image quality. For photographs, a moderate reduction is often a good starting point.

Check the compressed preview at a useful viewing size. Look for blurry text, blocky areas, banding or obvious loss of detail.

When the result looks good, download it and keep the original separately. Rename the output if it is going into a website or project.

Compress a copy rather than overwriting your original.
For web images, reduce unnecessary dimensions as well as quality when the tool provides that option.
Compare file size and appearance together; the smallest file is not always the best file.

What image formats can I compress?

The SmartToolz Image Compressor supports JPG, PNG and WebP according to the tool description.

Should I use maximum compression?

Not automatically. Choose the strongest reduction that still preserves the details your image needs.

Why can two images with the same dimensions have different file sizes?

Compression, image content, metadata and the original encoding can all affect file size.
