Choosing the right image size before uploading can make pages faster, layouts cleaner, and forms easier to submit. Large photos from a phone or camera are often several thousand pixels wide, while many website cards, thumbnails, and social previews display at much smaller dimensions.

Match size to the destination

Start by asking where the image will appear. A profile photo usually works best as a square image. A blog header or website banner usually needs a wider crop. A product thumbnail needs enough detail to stay clear in a grid, but it does not need the full resolution of the original camera file.

  • Profile images: Use a square crop, often 800 by 800 pixels or larger before final compression.
  • Blog and article images: A width around 1200 pixels is usually enough for a clear web display.
  • Thumbnails: Keep them smaller and consistent so repeated cards load quickly.
  • Social sharing images: Use a landscape crop when the platform shows link previews.

Resize before you compress

Compression is more effective after dimensions are reasonable. Use the Image Resizer first when the image is physically too large, then use Compress Image if the file size is still too heavy for a website, email, or upload form.

Check the final page

After resizing, preview the image in the actual layout. Look for blurry text, awkward cropping, faces cut off near the edge, or a file that still takes too long to load. Keep the original file in case you need a different crop later.
