Resize to 5×5 cm — runs in your browser

When you're preparing an image for print, pixels are awkward — you think in centimetres. This tool lets you type the width and height directly in cm and converts to pixels at 300 DPI behind the scenes.

The resize runs in your browser, so your image is sized for print without being uploaded.

How to use Resize Image in Centimetres

Using Resize Image in Centimetres takes only a few seconds and just four simple steps — no sign-up, no software, and nothing to learn:

  1. Upload the image: Add the photo you want to resize for print.
  2. Enter cm: Type the width and height you need in centimetres.
  3. Resize: The tool converts cm to pixels at 300 DPI and scales the image.
  4. Download: Save the print-sized image.

What you can do with Resize Image in Centimetres

Resize Image in Centimetres is built to do one job well, and gives you everything you need to get it exactly right:

Centimetre input. Type real print dimensions instead of calculating pixels.

300 DPI conversion. Handles the cm-to-pixel maths automatically for sharp prints.

Switch units anytime. Flip between cm, mm, inches, and pixels as needed.

Free and private. Resized in your browser with no watermark.

Think in print sizes, not pixels

Photo labs and forms quote sizes in centimetres. Entering cm directly here removes the error-prone step of converting to pixels yourself before you print.

Whether you need it once or every day, Resize Image in Centimetres keeps the process quick and predictable. Because it focuses on a single task, there are no crowded menus to wade through — you open the page, set what you need, and get your result. That simplicity is exactly why a dedicated image tool beats a heavyweight editor for a job like this.

Everything runs in your browser

Unlike most online tools, Resize Image in Centimetres never uploads your image to a server. The moment you choose a file, it is processed right here in your web browser using your own device's power. Nothing is sent over the internet, nothing is stored, and nothing is shared with anyone.

That gives you two real advantages. First, it is private: sensitive documents, ID photos and personal files never leave your computer or phone. Second, it is fast — there is no slow upload or download round-trip, so even large files are handled almost instantly. And it is completely free, with no watermark added to your result and no account required.

Tips for the best results

  • Start from the highest-quality original you have — the better the input, the better the result from Resize Image in Centimetres.
  • Check the exact requirement — size, dimensions, or format — before you begin, so you only need to do it once.
  • Centimetre input: Type real print dimensions instead of calculating pixels.
  • 300 DPI conversion: Handles the cm-to-pixel maths automatically for sharp prints.
  • Everything is repeatable — if the result isn't quite right, just adjust the settings and run it again. Nothing is uploaded, so you can try as many times as you like.
