About Photo Size Reducer

Plenty of forms, portals and email systems turn a photo away because it is a few kilobytes over a limit. The message is short, the deadline is not, and the usual advice is to install something or upload your picture to a stranger's server. This site exists to make that problem quicker to solve.

How it works

You choose a picture and type the size you need, in KB or MB. The tool opens the picture inside your browser, saves it as a JPG at a series of quality levels, and keeps the best one that fits. If even a low quality is too big, it reduces the width and height in small steps and searches again. You see the final size and a preview before you download.

Because all of this happens on your own device, the photo is never sent to us. There is no account to make and no watermark on the result.

What it does not do

It changes file size, not the exact pixel dimensions, background colour or framing that a particular portal may ask for. It saves JPG files only. On the website it handles one picture at a time. And it cannot promise that a third party will accept a file, because those services apply their own checks. The size pages explain these limits in more detail, for example the page on passport photos.

The Android app

The same idea is available as a free to download Android app. It can compress several photos in one go and works without an internet connection. The free version has a daily limit and shows ads, and there is an optional paid plan that removes them.
