How It Works

Step-by-step guide to resize image to 2x4.5 centimeters to exact specifications

Upload Your Image

Drag and drop a JPG, JPEG, PNG, WebP, or HEIC file onto the page, or click to pick one from your camera roll. A photo of a signature on white paper works as well as a portrait.

Check The 2x4.5 cm Frame

The 2x4.5 cm target is already applied, so there are no numbers to enter. If your photo has a different shape, pick a fit mode: Crop, Add Padding, Fill Frame or Stretch image.

Preview And Download

Check the preview, then download your 2x4.5 cm image. The whole job ran in your browser, so nothing was uploaded. Clear the files afterwards if you share the device.

Why Choose Imresizer?

Fast, secure, and completely free image resizing

  • Exact 2x4.5 cm Size

    The 2x4.5 cm size is already applied, so you don't do any unit math. The output is 236x531 pixels at 300 DPI, which matches a 20x45 mm box on a form or a print order sheet.

  • Four Fit Modes

    A 2x4.5 cm frame is tall and narrow, so most photos don't match it. Pick Crop, Add Padding, Fill Frame or Stretch image to decide what happens to the extra width, instead of getting a distorted face.

  • Files Never Leave Your Device

    Everything runs inside your browser and nothing is sent to a server. That matters when the file is a face photo or a signature that you'd rather not hand to an unknown website.

  • Preview Before You Download

    You see the 2x4.5 cm result before you save it. If a face is cut off or the signature looks squeezed, switch the fit mode and check again in seconds.

  • Works On Your Phone

    Pick a photo from your camera roll or a signature you photographed on paper, resize it, and save it back to your phone. No app to install, so you can finish a form from the same device.

  • Quick Even For Big Photos

    A 12-megapixel camera photo is scaled down to 236x531 pixels in a moment, because the work happens on your own device. There's no upload queue and no waiting on a slow connection.

  • Free With No Daily Cap

    No account, no watermark, and no limit on how many images you resize. Come back whenever the next form asks for the same size.

Frequently Asked Questions

Everything you need to know about image resizing

How do I resize an image to 2x4.5 cm?

Upload your photo and the 2x4.5 cm size is already set. Choose a fit mode if the shape differs, check the preview, then download. It runs in your browser, with no software to install and no account needed.

What is 2x4.5 cm in pixels?

At 300 DPI, 2 cm is about 236 pixels and 4.5 cm is about 531 pixels, using pixels = cm / 2.54 x DPI. This page builds the file at 236x531 pixels, so you don't have to convert by hand.

What is 2x4.5 cm in pixels with 200 DPI?

At 200 DPI the same size is about 157x354 pixels. DPI only describes print density, so the centimeter size stays the same. This page always outputs 236x531 pixels, which prints at 2x4.5 cm at 300 DPI.

How many inches and millimeters is 2x4.5 cm?

2x4.5 cm is about 0.79x1.77 inches, or 20x45 mm. If a form or print lab gives the size in another unit, these figures describe the same physical box.

Which fit mode should I use when my photo is not 2x4.5 cm shaped?

Stretch image forces the photo into the frame and distorts it. Crop keeps proportions and cuts off what falls outside. Add Padding keeps the whole image and fills the leftover space with colored bars. Fill Frame scales the image up to cover the frame and trims the overflow. For a face, Crop or Fill Frame avoids a stretched look. For a signature, Add Padding keeps every stroke.

Can I resize a signature to 2x4.5 cm?

Yes. Photograph your signature on plain white paper in good light, upload it, and use Add Padding so none of the strokes get cut off. Check the preview to confirm the signature is still easy to read.

Which form fields ask for a 2x4.5 cm image?

Form makers set their own sizes, and some exam and application forms list a box near 2x4.5 cm for a photo or signature. Always check the exact size and file type printed on your form.

Are my images uploaded to a server?

Nothing is uploaded. Resizing runs entirely inside your browser on your own device, so the photo never touches an external server. It stays private from upload to download.

Is it free to resize an image to 2x4.5 cm?

Every part of it is free, with no account, no trial period, and no watermark on the downloaded file. There's no daily cap either.

Which file formats can I upload and download?

You can upload JPG, JPEG, PNG, WebP or HEIC, including the HEIC files an iPhone saves. The download is a JPG by default, which most forms accept. Read the accepted list on your form before you submit.

My form also has a file size limit. What do I do?

Resize to 2x4.5 cm here first, then use the Resize Image Size in KB page to bring the file under the limit your form states. Doing the size first keeps the file as sharp as the limit allows.

Does this work on a phone?

It runs in any modern mobile browser, so you can choose a photo from your camera roll without installing an app. The finished image saves to your device, ready to attach to the form.
