Resize Image

Change an image's width and height in pixels or by percentage, with the aspect ratio locked or free.

Resize Image changes the pixel dimensions of a photo or graphic. Use it to make a large camera photo small enough for email or a website, or to meet an exact size such as 1080 × 1080. You can type a width and height or scale by a percentage from 10% to 300%, and the Prevent Upscaling option stops you from enlarging an image by mistake.

How to use Resize Image

  1. 1

    Open your image

    Drop, choose or paste (Ctrl+V) a JPG, PNG, WebP, AVIF or iPhone HEIC image.

  2. 2

    Set the new size

    In Pixels mode, type a width or height; with Lock Aspect Ratio on, the other side updates automatically. In Percentage mode, use the slider or the 25% to 200% buttons.

  3. 3

    Choose the file format

    The original format is kept by default. You can switch to JPG, PNG, WebP or AVIF and set the quality for JPG, WebP and AVIF.

  4. 4

    Download the result

    Click Download to save the resized image, or send it to Compress if you also want a smaller file size.

What it does

Pixels or percentage
Type exact dimensions up to 10,000 pixels, or scale the whole image from 10% to 300%.
Aspect ratio lock
Keep the original proportions so the image is not stretched, or unlock it to set width and height separately.
Prevent upscaling
Limits the size to the original dimensions, so a small image is never enlarged and made blurry by accident.
Keeps your file type
A JPG stays a JPG and a PNG stays a PNG, unless you choose a different format.

Questions

How do I resize an image without losing quality?

Making an image smaller keeps it sharp. Making it larger than the original cannot add detail, so it will look softer; turn on Prevent Upscaling to avoid this. Save as PNG, or use 90% quality or higher for JPG and WebP.

Does resizing reduce the file size?

Usually, yes. Halving the width and the height leaves about a quarter of the pixels, so the file becomes much smaller. For even smaller files, compress the result afterwards.

Can I resize to an exact size like 1080 × 1080?

Yes. Turn off Lock Aspect Ratio and type both numbers. If the original is not square, it will be stretched, so crop it to 1:1 first and then resize.

Can I resize many images at once?

This page resizes one image at a time. To resize up to 50 images in one step and download them as a ZIP, use the Bulk Image Resizer.

Can I resize photos from my iPhone?

Yes. HEIC photos are converted in your browser and the resized image is saved as JPG by default.
