How to use the Image Resizer

  1. Choose files, drop them on the page, or paste an image with Ctrl+V (⌘V on a Mac).
  2. In the New size card, pick a preset, or choose Resize by Pixels, Percentage or Print size and fill in the numbers.
  3. If the shape changes, choose how to fit it: Crop to fill, Fit with padding or Stretch. Select Apply changes if the image is already showing.
  4. Select Download, or Download all (ZIP) when you resized several images.

Three ways to say how big

The New size card starts with Resize by, and the choice depends on what you were told to deliver.

Pixels is for websites, forms and apps that name an exact size. Type a width, a height or both. Lock aspect ratio is on by default, so typing one side fills in the other and the picture keeps its shape. Switch it off when you need an exact width and height that don't match the original.

Percentage is for "make it smaller" without doing math. Slide or type a value from 1 to 400, or use the 25%, 50% and 75% buttons.

Print size is for paper. Enter a width and height in inches or centimeters, plus the DPI (it starts at 300). The tool shows the result in pixels, for example 4 x 6 in at 300 DPI is 1,200 x 1,800 px. DPI is saved in JPG and PNG files, but it doesn't change how many pixels the image has, and screens ignore it.

Making an image bigger can't add detail that was never there. A small photo stretched to a large size will look soft, so start from the largest original you have.

When the new shape is different: crop, pad or stretch

If you ask for a shape that doesn't match the original, such as a wide photo going into a square, the image has to give somewhere. The Fit control decides how.

  • Crop to fill covers the whole new frame and trims the edges that don't fit. It crops around the center, and you can choose what stays in view from an image's own settings.
  • Fit with padding shows the entire picture and fills the leftover space with a color. Pick white, black or any color. With Auto, padding is transparent in PNG and WebP and white in JPG.
  • Stretch forces the picture into the new shape. It can distort faces and logos, so use it only when you mean it.

A small preview shows where the picture will land before you download. If you only need to cut away part of a photo without changing its size, the Crop Image tool lets you drag the area directly.

Presets for the places you post

Instead of looking up a size, pick one from the presets. They cover Instagram, YouTube, Facebook, LinkedIn, X, TikTok and Pinterest, plus the 2 x 2 in US passport photo size. Choosing one sets the exact width and height and switches to Crop to fill.

Each platform has a page that goes deeper than a size list. Our Instagram image size guide covers square, portrait and story posts, and the YouTube thumbnail size page covers 1280 x 720 and the 2 MB upload limit.

Resizing also changes the file size, but not always the way you want. For a hard limit, open Advanced settings (optional), go to Compression and choose Keep under. It lowers the quality until the file fits and leaves your pixel dimensions alone. Set the output to JPG, PNG or WebP, or leave it on Same as original.

Add a whole folder of images and they all get the same size. Give one of them its own settings from its row if it needs something different.

Frequently asked questions

How do I resize an image without losing quality?

Make the image smaller, not larger, and save it as PNG or at a high JPG quality. Shrinking keeps a picture sharp, because the tool only removes pixels. Enlarging cannot add detail that was never captured, so the result looks softer the more you stretch it.

How do I resize an image to a specific size in pixels?

Choose Resize by Pixels, then type the width and height you need. If the original has a different shape, pick Crop to fill, Fit with padding or Stretch to decide what happens at the edges. Turn off Lock aspect ratio when you need both numbers exactly.

How do I resize an image to 4x6 inches?

Choose Resize by Print size, enter 4 and 6 with the unit set to in, and keep the DPI at 300. The tool then shows 1,200 x 1,800 px as the result. A lab prints from pixels, so a 300 DPI file at that size gives a sharp 4 x 6 in print.

What is the difference between resizing and compressing an image?

Resizing changes the width and height in pixels, while compressing changes how tightly the file is stored. A smaller image usually makes a smaller file too. If you only need a smaller file and want to keep the pixels, use Compress Image or the Keep under option in Advanced settings.

Can I resize many photos at once?

Yes. Add all your photos, choose the size once, and every file gets it. Download all (ZIP) bundles the results into one archive. If a single photo needs a different size or crop, open its settings button and change it there without affecting the others.

Is it safe to resize private photos here?

Yes. Your photos are resized in your browser on your own device and are never uploaded. No account is needed. The Advanced settings also remove location and camera details from the saved copy by default, which helps when you share the resized photo.
