Resize images, right in your browser.

Set a width, a height or both in pixels. Leave one blank to keep the proportions. Free, many files at once, and nothing is uploaded.

Runs on your device. Your files never leave this browser.

Try it offline

Open this page once and wait until it says it works offline.
Turn off Wi-Fi and mobile data, or switch on airplane mode.
Reload the page. It still opens and still works, because nothing needs the internet.

Developers: open DevTools → Network before choosing a file. Processing makes no requests. Afterwards the page sends one anonymous count (which tool, how many files) to our own statistics server, never a file or its name, and the page's Content Security Policy blocks every other site.

How to resize an image

Enter the width you want in pixels and leave the height blank, so the photo keeps its shape. Or set the height and leave the width blank.
Set both only when you need an exact size, for example 600 × 600. A photo with a different shape will then be stretched to fit.
Choose your images, then download them one by one or as a zip.

Which size should I use?

Sharing or email: 1080 to 1600 pixels wide looks sharp on phones and keeps files small.
Online forms: use the exact size the form asks for. If it also has a size limit in KB, use the image compressor afterwards, or a ready-made page like compress to 50 KB.

Questions

Are my photos uploaded?

No. Resizing runs inside your browser tab, on your device. "Try it offline" at the top of this page shows how to check.

What format do I get back?

PNG files stay PNG, so transparency is kept. Everything else is saved as a high-quality JPG.

Can I make a photo bigger?

Yes, but enlarging can't add detail that isn't there, so it will look softer.
