Resize a photo to 3.5 × 4.5 cm

3.5 × 4.5 cm is the photo size many application forms ask for. At 200 DPI that's 276 × 354 pixels. We crop your photo from the centre to that shape and compress it to your KB limit.

Compress your photo

Photo

Size limit

We keep the file just under the limit, counting 1 KB as 1,000 bytes, so it passes on every portal.

More options: exact pixel size, DPI

We crop from the centre to match this shape, so faces never get stretched.

It changes the label inside the file, not the pixels.

We check the size against your limit before you download. Nothing is uploaded.

Getting it right

  • Files have pixels, not centimetres: forms convert with DPI (dots per inch). At 200 DPI, 3.5 × 4.5 cm is 276 × 354 px. At 300 DPI it's 413 × 531 px.
  • If your form says 300 DPI, open More options and enter 413 × 531 and DPI 300.
  • Keep your face in the middle of the picture: the crop is taken from the centre.
  • Use a plain, light background and even light on your face.

Exams that ask for this

These pages have the official size and rules already set:

How it works

  1. Choose your photo. A JPG, PNG or WebP from your phone or computer.
  2. Type the limit from your form. If it says “between 20 KB and 50 KB”, enter 20 and 50.
  3. Download. You get a JPG that fits, usually within a second or two.

Your photo never leaves your device

The compression runs inside your browser. Your photo is not uploaded to any server, so nobody else can see it. That matters for ID photos and signatures. See how to check it yourself.

Tips for application forms

  • Copy the numbers exactly as the form states them. Forms reject a file that is even 1 KB over the limit.
  • If the form gives a pixel size, such as 350 × 450, open More options and enter it.
  • If the form mentions 300 DPI, enter 300 in the DPI box. It changes a label inside the file, not the photo.
  • For a very small limit, crop the photo close to the face or signature first. Less background leaves more detail for what matters.

Questions

Will my photo lose quality?

Some, as with any compression. We test several combinations of pixel size and quality and keep the one that looks best while staying under your limit.

Why is the file a little under my limit?

We aim for 95–100% of the limit, so the file is never over it. A form will accept 48 KB when the limit is 50 KB.

My form needs at least 20 KB. Can you make a file bigger?

Yes. Enter the minimum in the first box. If the photo is too small, we raise the quality first. If it is still under, we add harmless padding inside the file. The photo looks exactly the same.

What does the exact pixel size option do?

It resizes the photo to those pixels. If the shape is different, we crop from the centre so nothing gets stretched.

Which files can I use?

JPG, PNG and WebP. The result is always a JPG, which every form accepts.

Is it free?

Yes. There is no sign-up and no watermark.
