What this image compressor does

It makes image files smaller so your pages load faster, your emails send more easily and your uploads finish quicker. You can reduce the quality slightly, resize large photos, and convert them to WebP, a modern format designed for the web.

Many online compressors upload your photos to a server. This one works inside your browser, so your images stay on your device.

How to use it

Choose your images or drag them onto the box.
Pick a format and maximum width. WebP at 1600 pixels is a good starting point for most websites.
Compare the file sizes, and open the result to check that it still looks good.
Download each image, or all of them together.

Change a setting at any time and the images are compressed again from your originals.

Why image size matters for marketing

Large photos are one of the most common reasons small business websites feel slow, especially on a phone. Often the biggest image on a page is the one that decides how quickly the page seems to load, which Google measures as Largest Contentful Paint. Our guide to Core Web Vitals explains how that works.

A photo straight from a phone can be several megabytes and thousands of pixels wide, yet appear at around 1,200 pixels on your page. Resizing it first often saves more than any quality setting.

Which settings should you choose?

Where the image is used	Suggested width	Format
Full-width website banner	2000 px	WebP
Blog or article image	1200 px	WebP
Product photo in a grid	800 px	WebP
Email or a platform that rejects WebP	1200 px	JPG

These are starting points, not fixed rules. If your layout shows an image at a different size, match that instead, and allow extra width for sharp phone and laptop screens.

Good to know

Compression is usually permanent. Keep your original files, and compress from those rather than from a compressed copy.
Logos and screenshots behave differently. Sharp edges and text can show blur at low quality, so raise the quality for those.
Transparency needs the right format. WebP and PNG can keep a transparent background. JPG can't, so transparent areas turn white.
Photo details are removed. The compressed copy doesn't keep extra data such as camera details or location, which is usually good for privacy. Keep your original if you need that data.
If an image won't get smaller, it's probably well optimised already, so we give you the original rather than a larger file.
