Free online image resizer
Resizing an image changes its pixel dimensions. This is useful when a website, application, social platform, document, or online form requires a specific image width or height.
PicSqueezer lets you resize images directly in your browser without installing image-editing software. You can enter exact dimensions and keep the aspect ratio locked when you want to preserve the original shape of the photo.
How to resize an image
- Upload the image you want to resize.
- Enter the desired width and height in pixels.
- Keep the aspect ratio locked if you do not want the image stretched.
- Resize and download the new image.
Common reasons to resize an image
Website images
Resize oversized photos before adding them to a website so the browser does not need to display unnecessarily large images.
Social media
Create images at dimensions suitable for different social platforms and content formats.
Online forms
Some applications require images to fit specific width, height, or upload requirements.
Email and messaging
Reducing image dimensions can also reduce file size and make photos easier to share.
Resize vs. compress an image
Resizing changes the number of pixels in an image. Compression changes how efficiently those pixels and other image data are stored. They are related but different operations.
If your image has the right dimensions but the file is too large, use Compress JPG or Compress PNG.
Keep the aspect ratio to avoid distortion
An image's aspect ratio is the relationship between its width and height. For example, changing a 1600 × 900 image to 800 × 450 keeps the same 16:9 proportion. Changing it to 800 × 800 would stretch or distort the original composition.
For normal photo resizing, keep the aspect ratio locked. Only enter independent width and height values when the destination specifically requires exact dimensions and distortion is acceptable.

Frequently asked questions
How do I resize an image online?
Upload your image, enter the width and height you need, and use the resize tool to create a new image at those dimensions. You can keep the aspect ratio locked to prevent stretching.
Can I resize an image to exact pixels?
Yes. You can enter exact width and height values in pixels. Keep the aspect-ratio lock enabled when you want the image to maintain its original proportions.
Will resizing an image reduce its quality?
Reducing the dimensions of an image generally produces a sharp result, although some fine detail is lost because there are fewer pixels. Enlarging an image can make it appear softer because new pixels have to be generated.
Does resizing an image reduce the file size?
Usually. A smaller image contains fewer pixels, so the resulting file commonly requires less storage space. If you need maximum size reduction, you can resize first and then use an image compressor.
Can I resize JPG, PNG, and WEBP images?
Yes. Common image formats such as JPG, PNG, and WEBP can be resized in a modern browser. PNG transparency can be preserved when the output remains PNG.
Can I resize an image without stretching it?
Yes. Keep the 'Lock aspect ratio' option enabled. This keeps the relationship between width and height consistent while you change the image dimensions.
Are my images uploaded to a server?
No. Image resizing is performed directly in your browser using client-side processing. Your original image does not need to be uploaded to PicSqueezer.
