Try the image compressor

Three simple steps

1

Upload your image

Drop in a photo or graphic up to 16 MB.

2

Set the quality

Slide toward a smaller file or toward best quality. 70 is a sensible balance for most photos.

3

Download the smaller file

Run it and save a lighter image that still looks right on screen.

Make images small enough for the web and email

A photo straight from a phone or camera can be several megabytes. That is fine to keep, but far too heavy for a web page, a newsletter or a messaging app. Compression rewrites the image data so the file is dramatically smaller while the picture still looks right to the eye.

How much quality should you keep?

img.now gives you a single quality slider so you stay in control:

Best (around 85) - Almost indistinguishable from the original, good for portfolios and print previews.
Balanced (around 70) - The web standard; big savings, no obvious loss.
Small (around 45) - Maximum savings for thumbnails and backgrounds where size matters more than fine detail.

Photographs and screenshots respond differently, so the live result lets you judge the trade-off for your specific image rather than guessing.

Compress as part of a pipeline

For the lightest possible file, first resize to the dimensions you actually display at, then compress. If you also need a different format, the converter can turn the result into WebP, which is smaller again than JPG at the same quality. Every compressed image is saved in your img.now workspace so you can grab it whenever you publish.

Want a different file type as well? The file converters turn your image into PNG, JPG, WebP, AVIF and more.

Questions about the image compressor

How much smaller will my file get?

It depends on the image, but photographs commonly drop by 60-90% with little visible change. Detailed or noisy images compress less; flat graphics and screenshots compress a lot.

Does compressing lose quality?

Compression trades a little detail for a much smaller file. At a quality of 70-85 the difference is hard to see at normal viewing size, which is why it is the standard for the web. Lower settings shrink more but start to show artefacts.

What is the difference between compressing and resizing?

Compressing keeps the same pixel dimensions and reduces the file size by encoding more efficiently. Resizing changes the dimensions. For the smallest possible file, resize to the dimensions you actually need, then compress.

Why compress images at all?

Smaller images load faster, use less data, rank better for Core Web Vitals, and slip under email and upload size limits. A heavy page full of uncompressed photos is the most common cause of slow load times.
