Why image size matters for your website
Large images are one of the most common causes of slow-loading pages. Every visitor has to download the full file before they can see it, and that adds up fast on a page with several photos.
Compressing images reduces file size — often dramatically — with little to no visible quality loss at normal viewing sizes, which means faster page loads without redesigning anything.
Which format should you choose?
- ✓WebP — usually the best choice. Strong compression, supports transparency, and is well supported by modern browsers.
- ✓JPEG — good for photos, widely compatible, but doesn't support transparency.
- ⚠PNG — best kept for images that need transparency and can't use WebP. Re-encoding through a browser rarely shrinks PNG files much, since PNG compression is lossless by design.
Frequently asked questions
Is my image uploaded anywhere?
No — everything happens in your browser using the Canvas API. Your image is never sent to our servers.
What quality setting should I use?
Around 75-85% is a common sweet spot for photos — a good balance between file size and visible quality. Lower it further if the file size still matters more than quality for your use case.
Will this resize the image dimensions too?
Only if you enable "Resize to max width" — otherwise the image keeps its original dimensions and only the file size is reduced through compression.
