Resizing Images for Social Media and E-commerce: A Complete Guide

Introduction: Your Visual First Impression#

You upload a profile picture to LinkedIn, and suddenly it looks blurry. Or you list a product on Etsy, only to find the thumbnail cropped in awkward ways.

Sound familiar?

Your visuals are often the first impression people have of your brand. If they look unprofessional, inconsistent, or low-quality, it can cost you engagement, trust, and even sales.

The solution? Use the right image sizes — for every social platform and e-commerce site. In this guide, we’ll break down the exact dimensions you need, plus show you how to resize and compress them perfectly using Photo Resizer in KB.

Why Size Matters for Your Brand#

• Professional appearance → Your logo and photos look crisp, not pixelated.
• Consistent branding → Uniform image sizes across platforms make your brand recognizable.
• Better engagement → Posts that look good get more clicks, shares, and sales.
• Platform compliance → Avoid rejection, cropping, or compression by following the rules.

And don’t forget: most platforms also have file size limits in KB. That’s where presets like 20KB, 50KB, and 100KB come in handy.
