What is pixel size?

Every digital picture is made of tiny squares called pixels. The pixel size – for example 1200 × 800 px – is the number of pixels across and down. Websites, apps and online forms often ask for an exact pixel size, and a photo straight from a phone camera is usually far bigger (4000 × 3000 px or more).

Common pixel sizes

Instagram post 1080 × 1080 px · story 1080 × 1920 px
Facebook cover 851 × 315 px · YouTube thumbnail 1280 × 720 px
Profile pictures 400 × 400 px
Online form photos often 200 × 230 px – use the Photo & Signature Resizer when the form also sets a KB limit

Pixels, KB and DPI – what is the difference?

Pixels are the picture’s width and height. KB is the file size on disk – to reach a KB limit use Resize Image to KB. DPI only says how big the picture prints on paper; for printing at a set size in cm or inches use Resize Image with the cm or inch option.

Tips

Making a picture smaller in pixels keeps it sharp. Making it much bigger cannot add detail, so it may look soft.
To change the shape (for example a tall photo into a square) without stretching, crop the image first.

Frequently asked questions

How do I change the pixel size of a photo?

Choose your photo, keep Pixels selected, type the new width or height and press Resize. Download the picture at its new size.

Can I change the pixel size without stretching the picture?

Yes. Leave “Keep the shape” on and type only the width or only the height – the other side is worked out for you.

Will changing the pixel size reduce quality?

Making a picture smaller keeps it sharp. Making it much larger than the original can look soft, because no new detail can be added.

Does changing pixels change the KB size?

Yes, fewer pixels means a smaller file. For an exact KB limit, use Resize Image to KB.

Can I resize many photos at once?

Yes. Select several pictures and they are all resized together, then download them one by one or as a ZIP.

Are my photos uploaded?

No. The pictures are resized on your own device and never sent anywhere.
