Resize photos and graphics to the right width and height for web pages, profile images, social posts, and uploads.

How to Resize an Image Online for Websites, Social Media, and Documents

Using the right image dimensions matters. An image that is too large wastes bandwidth and storage, while an image that is too small can appear blurry or pixelated. Filego Image Resizer provides a browser-based way to resize images for websites, social media, documents, and uploads.

Use Filego Image Resizer.

Image resizing is not just about changing numbers. It helps you match the image to where it will be displayed. A website hero image, ecommerce product photo, profile image, blog thumbnail, and presentation slide all need different dimensions.

Common reasons to resize an image

  • Make a photo fit a website layout
  • Create consistent ecommerce product images
  • Prepare a social-media post or profile image
  • Meet image-upload requirements
  • Reduce oversized image dimensions before compression

How to resize an image online

  1. Open Filego Image Resizer.
  2. Upload your photo, screenshot, or graphic.
  3. Enter the width and height required for the destination.
  4. Keep the aspect ratio when you want to avoid stretching.
  5. Download the resized image and test it where it will be used.

Preserve the correct aspect ratio

An aspect ratio is the relationship between an image’s width and height. If you change one dimension without preserving that relationship, faces, logos, products, and text can look stretched. When possible, resize proportionally and crop separately when a fixed shape is required.

For example, if a product photo is designed for a square product grid, crop it to a square first and then resize it to the display dimensions. This keeps the product centered and prevents inconsistent listing cards.

For most websites, resize the source image, compress it, and then convert it only if the destination needs a different file format. Explore more workflows in Filego Image Tools.
