How to Use Image Resizer
Upload your image
Drag and drop an image or click to browse. The tool accepts JPEG, PNG, and WebP, so you can resize photos, screenshots, graphics, and other web images in one place. Your original image preview and current dimensions are shown immediately.
Choose pixels or percentage
Resize by exact width and height in pixels, or switch to percentage mode to scale the image up or down from its original size. This is useful when you want to resize a picture to exact dimensions like 1200×630, 1080×1080, or 1920×1080, or simply make an image 50% smaller while keeping proportions.
Pick the right resize mode
Use Exact size if you want the output forced to your dimensions, even if that stretches the image. Use Fit inside to resize without losing aspect ratio. Use Fill and crop when you want a fixed frame with no empty space. Use Fit with padding when you want the whole image visible inside an exact canvas size with a background color around it.
Rotate, flip, preview, and download
If needed, rotate the image, flip it horizontally or vertically, then preview the resized result. Choose PNG, JPEG, or WebP as the output format and download the final file. Use "New image" to start again with another picture.
Calculator Features
Resize image to exact dimensions
Enter any width and height in pixels to resize an image for websites, blogs, product listings, social media posts, banners, thumbnails, or profile pictures.
Resize by percentage
Scale an image by percentage when you want to make a photo smaller or larger without manually calculating the new dimensions.
Fit, crop, stretch, or pad
Choose Exact size, Fit inside, Fill and crop, or Fit with padding so the output matches your layout, design, marketplace, or social media requirement.
Rotate and flip before export
Rotate a photo 90° or 180° and flip it horizontally or vertically before resizing, so you can fix orientation and prepare the final image in one tool.

Common Calculations & Examples
Example 1: Resize image for Instagram or social media
Problem: You need to resize a photo for Instagram, a square social graphic, a story post, or a social preview without guessing the dimensions.
Steps:
- Upload your photo or graphic.
- Choose a preset like 1080×1080 for Instagram square or 1080×1920 for story format.
- Use Fill and crop for a full frame, or Fit inside if you want to preserve the whole image.
- Preview and download the resized image in PNG or JPEG.
Explanation: This helps when you need to resize a picture for Instagram, social posts, thumbnails, or other platform-specific dimensions while keeping the output clean and consistent.
Example 2: Resize image for Open Graph, blog, or website banner
Problem: Your website, article, or landing page needs an image at exact dimensions such as 1200×630, 1920×1080, or another custom banner size.
Steps:
- Upload the image you want to use on your website.
- Apply the Open Graph preset or enter your own width and height in pixels.
- Choose Fit with padding, Fit inside, or Fill and crop depending on whether you want the full image visible or edge-to-edge coverage.

Explanation: This is useful when you need an online image resizer for websites, Open Graph images, hero banners, or blog thumbnails without opening design software.
Example 3: Resize product photos or marketplace images
Problem: You need product images in a uniform size for an online store, catalog, or marketplace listing.
Steps:
- Upload the product photo.
- Enter the required dimensions or use a preset that is close to your target.
- Choose Fit with padding if you want the whole item visible on a fixed canvas, or Fill and crop if you want every tile fully filled.
- Download the result in JPEG, PNG, or WebP.
