Why image size makes or breaks your site speed

Images are usually the heaviest thing on a web page, and slow pages lose visitors and rankings. Compressing your images — reducing their file size without a visible drop in quality — is one of the fastest ways to speed up a website. This tool does it entirely in your browser using canvas, so your images are never uploaded anywhere. Drop one in, dial the quality, and download a much smaller file.

How to use the image compressor

Choose an image from your computer or phone.
Adjust the quality slider — 70 to 80 percent usually looks identical at a fraction of the size.
Pick a format. WebP gives the smallest modern files; JPG is universally supported.
Optionally cap the width so huge photos are scaled down to a web-friendly size.
Download your compressed image and upload it to your site.

Too Many Images To Compress By Hand?

Compressing images one at a time is fine for a few — but on a real website with hundreds of images, you want it automatic. We can manage this for you: we install automatic image optimization on your WordPress site so every image is compressed and converted to next-gen formats on upload, keeping your site fast without you lifting a finger.

Common Questions

Image Compressor FAQ

Does compressing an image reduce its quality?

Lossy compression removes detail the eye barely notices, so at 70 to 80 percent quality most images look identical while the file size drops dramatically. You can preview the result here and adjust the slider until you find the best balance of size and quality for your image.

Are my images uploaded anywhere?

No. This compressor runs entirely in your browser using HTML canvas. Your image never leaves your device, which makes it both private and instant — there is no upload or download wait.

What is WebP and should I use it?

WebP is a modern image format that produces smaller files than JPG or PNG at the same quality, and it is supported by all current browsers. It is an excellent choice for website images. Use JPG only if you need to support very old software.

How much should I compress images for my website?

Aim to get most web images well under 200 KB, and scale them down so they are no wider than they will actually display. For a site full of images, automatic optimization that compresses everything on upload is the reliable approach — which is something we can set up and manage for you.
