  • Download the resized picture

Resize an Image and Change Its Width and Height

Type the exact width and height you want in pixels and this free image resizer rebuilds your picture at that size. Use it to make a picture bigger, scale a photo down to fit a page, or simply make a picture the right size for a form that is asking for exact photo dimensions. Leave Keep Aspect Ratio ticked and the second box fills itself in, so the image never comes out stretched.

How to Resize an Image

  1. Click the upload area above or drag and drop your image (up to 7 MB).
  2. Enter a new width or height in pixels. With Keep Aspect Ratio on, the other value follows automatically.
  3. Untick Keep Aspect Ratio only if you deliberately want to squash or stretch the picture to fixed dimensions.
  4. Download the resized image.

Width, Height and Aspect Ratio

Every picture has a ratio between its width and height. A photo that is 4000 × 3000 has a 4:3 shape; force it into a 1000 × 1000 square and everything in it gets visibly squeezed. That is the single most common thing people get wrong when they resize a picture, and it is why the aspect lock is on by default here. Set one dimension, let the tool work out the other, and the image keeps its proportions.

If you genuinely need a square or a fixed banner size, resize with the ratio locked first and then crop to the shape you want. Cropping trims the edges instead of distorting what is inside.

Sizes That Usually Work

  • Full-width website image – around 1600–1920 px wide
  • Blog post or article image – around 800–1200 px wide
  • Email attachment or newsletter – around 1000–1600 px wide
  • Thumbnail or profile picture – 200–500 px square
  • Printing – keep the original size; printing needs more pixels, not fewer

When You Might Need This

  • A job application or government form that caps the photo at a set number of pixels
  • Product photos for a shop listing that all need to be the same size
  • A profile picture that has to be square and a specific size
  • Scaling a phone photo down before putting it on a website
  • Making a batch of holiday photos smaller so they fit on a memory stick
  • Preparing an image to a size a print shop has asked for

Key Features

  • Exact pixel dimensions – type the numbers rather than dragging a slider
  • Aspect ratio lock – resize without stretching or squashing
  • Bigger or smaller – scale a picture down, or enlarge it
  • Smooth resampling – bicubic filtering keeps edges clean rather than jagged
  • Private – files are deleted automatically within one hour, and nothing is watermarked

Supported Formats and Limits

Upload JPG/JPEG, PNG, WebP, GIF, BMP or TIFF, up to 7 MB. You can resize to anything up to 8000 × 8000 pixels, with a total of 50 megapixels. A transparent background stays transparent.

Frequently Asked Questions

Resizing changes the dimensions — how many pixels wide and tall the picture is. Compressing changes the file size in KB or MB while the picture stays the same dimensions. If a site says your image is too many pixels wide, resize it. If it says the file is too many MB, compress it. For a photo straight off a phone that is too big in both senses, resize first and then compress.

Because the width and height you entered do not match the original proportions. Forcing a 4:3 photo into a square squeezes everything horizontally. Tick Keep Aspect Ratio and enter only one dimension — the other is calculated for you, and the picture keeps its shape. If you need an exact square, resize with the ratio locked and then crop.

Only up to a point. Enlarging cannot invent detail that was never captured, so this tool stretches the pixels it has using bicubic resampling — fine for a modest increase, soft and mushy if you double or triple the size. For a real enlargement, use our AI Image Upscaler, which reconstructs detail instead of stretching it.

Usually yes, as a side effect. Fewer pixels means fewer bytes, and halving both width and height typically cuts the file to roughly a quarter. If the file is still too large afterwards, run it through Compress Image as a second step.

For most pages, 1600–1920 pixels wide covers a full-width banner, and 800–1200 pixels is plenty for an image inside an article. Anything much larger is downloaded by every visitor and then shrunk by the browser, which slows the page down for no visible benefit.

No. A PNG comes back as a PNG, a JPG as a JPG. To change the format, use Convert Image instead.

You can upload one image up to 7 MB and resize to any dimension up to 8000 × 8000 pixels, with a combined limit of 50 megapixels. If your file is over 7 MB, shrink it first with Compress Image.
