How to resize an image

  1. Add images

    Select or drop your images.

  2. Set the size

    Pixels, percent or cm/inches at a DPI. Or pick a preset.

  3. Download

    Get your resized images.

Everyday uses

  • Passport-size photos – 3.5 × 4.5 cm at 300 DPI for applications.
  • Form photos and signatures – exact pixel sizes asked by portals.
  • Social media – banners and profile pictures at the right size.
  • Printing – set the print size in cm or inches.

Good to know

Choose “Keep aspect ratio” to avoid stretching. When resizing to cm or inches the DPI decides the pixel size: 300 DPI is standard for print.

Need the file under a size in KB too? Tick “Limit the file size (KB)”: the image is saved as JPG at the highest quality that fits. For a minimum and maximum KB, use Resize image in KB.

Private by design. Resize Image works inside your browser. Your file is processed on your device and is not uploaded to our server.

Limits to know before you start

  • Enlarging cannot add detail, so big increases look soft.
  • If the new shape differs from the photo, choose crop, white border or stretch; stretching distorts faces.
  • The KB limit saves the image as JPG, so transparent areas become white. For a KB range (minimum and maximum), use Resize image in KB.

If something goes wrong

A picture will not open. The file may be damaged or in a format your browser cannot read. Convert it to JPG with Convert Image, or take a screenshot of it, and try again.

The photo looks stretched. Tick “Keep aspect ratio”, or choose Crop to fill or Fit with white border.

Resize Image – questions

How do I resize an image in cm?

Choose “cm”, enter width and height and a DPI (300 for print), then press Resize images.

Can I resize many images at once?

Yes. The same settings apply to every image.

Will enlarging make it blurry?

Enlarging can’t add detail, so big increases look soft.

Can I resize an image to a size in KB here?

Yes. Tick “Limit the file size (KB)” and enter the maximum. The image is saved as JPG at the highest quality under that size. For a range like 20–50 KB, use Resize image in KB.
