How to use Compress Image

  1. Choose or drag one or more images into the upload area.

  2. Set the quality, maximum width and output format. WebP usually gives the smallest result.

  3. Check the size saved, then download the results one by one or all at once.

Why image size affects speed and SEO

Images are often the heaviest part of a page. Oversized images slow loading, especially on mobile networks, and affect Largest Contentful Paint (LCP), one of the Core Web Vitals metrics Google looks at.

The two most effective steps: match the image width to the size it is displayed at (don’t upload a 4,000-pixel photo for an 800-pixel slot), then compress at a quality of 70–85, which is usually hard to tell apart from the original.

JPG, PNG or WebP?

JPG suits photos. PNG suits sharp graphics or images with a transparent background, but its files tend to be large. WebP handles both at a smaller size and is supported by all modern browsers, which is why it is the default in this tool.

Questions about Compress Image

Is my image uploaded to a server?

No. Compression runs entirely in your browser, so personal photos and documents never leave your device.

What quality do you recommend?

Start at 80. Lower it slowly until artifacts start to show, then raise it a little. For the web, 70–85 is usually enough.

Why is a PNG result sometimes larger than the original?

PNG is lossless, so it has no quality setting. For photos, choose WebP or JPEG. This tool tells you when the result is larger, and you can still keep the original file.

Does a PNG’s transparent background disappear?

If you convert to JPEG, transparent areas turn white. WebP and PNG keep the transparency.

Is location data (EXIF) carried over?

No. The image is redrawn when it is compressed, so metadata such as GPS location is not saved in the result.
