Updated: Apr 1

Let’s be honest—uploading mockups to your online store can feel like a game of “Will This Slow Down My Website?” You spent hours designing your artwork, but when it comes to presenting it online, your mockups need to be properly resized and optimized. Otherwise, your site might start acting like a turtle on a bad day (we don’t want that).


In this guide, we’ll break down how to resize and optimize your mockups so they look amazing and don’t make your website crawl at a snail’s pace. Let’s dive in!



1. Why Optimization Actually Matters (Other Than Making Your Life Easier)


Optimizing your mockups isn’t just for the techy folks behind the scenes—it's a win for everyone. Here’s why:

  • Speed, Baby: Big images = slow load times. And slow load times? They can make potential customers bounce faster than you can say “high bounce rate.”

  • SEO Love: Google’s into fast websites. The faster your images load, the more love you’ll get in search rankings. And people need to see your poster shop!

  • Mobile Magic: Most of your customers are probably shopping on their phones (we've all been there). Optimized images mean they won’t need to wait forever to see your gorgeous designs.

  • Sharp Looks: The right resizing keeps your images looking crisp and clear, not pixelated blobs.



2. Picking the Right Image Dimensions for Your Poster Shop


Each platform has its “ideal” image size. And while we’re all about quality, you don’t want to go overboard. Here’s the rundown:

  • Etsy: 2000px on the shortest side—don’t overdo it. Keep it sharp but efficient.

  • Shopify: 2048px x 2048px for square images. This size is perfect for your product pages—no complaints.

  • Print-on-Demand Sites: Check the specific platform’s requirements (but generally, keep your images around 1500px wide).

  • Website Banners: 1920px width for those full-screen hero images that scream “look at me!”



3. The File Format Dilemma (JPEG, PNG, and the Cool Kid, WebP)


Which file format is best? Well, it depends:

  • JPEG: Your go-to. Great for product images without taking up too much space.

  • PNG: Perfect for those with transparency needs. But, fair warning, they’re usually a bit larger in file size.

  • WebP: It’s new, it’s snazzy, and it’s great for keeping file sizes small while maintaining quality. Use this one if you’re into the latest tech.



4. Resizing Without Turning Your Image Into a Picasso (Keeping It Sharp!)


Resizing images doesn’t have to feel like a game of Jenga (fingers crossed). Try these tools to keep it smooth:

  • Adobe Photoshop: Go to File > Export > Save for Web. This helps shrink file size without making it look like a hot mess.

  • TinyPNG or ImageOptim: These tools will shrink your image down without crushing the quality. Magic.



5. Compressing for Speed 😎


If your mockups are still hefty after resizing, it’s time for some compression. The goal is to make them lighter without turning them into mush. Try these tools:

  • TinyPNG / TinyJPG: Upload your image and watch it get compressed to a fraction of its original size. Voila!

  • Squoosh: A Google tool to compress like a pro.

  • ShortPixel (for WordPress Users): Automates image optimization if you’re running a WordPress site—because who has time for manual compression?



6. Mobile Optimization (Because We All Shop on Our Phones)


Let’s be real—everyone’s browsing from their phones these days. Make sure your mockups look just as fab on mobile:

  • Use Responsive Images: Make sure your website automatically adjusts image sizes depending on the device. You don’t want it to look squished on a phone.

  • Test, Test, Test: Preview your mockups on different devices to make sure they look awesome everywhere.

  • Don’t Go Overboard: Keep file sizes under 500KB for mobile-friendly browsing. Your customers will thank you.



7. SEO-Friendliness (Google Is 👀)


Optimized images aren’t just for speed—they also help your SEO game. Here’s how:

  • Descriptive Filenames: “IMG_12345.jpg” isn’t helping anyone. Try something like “minimalist-poster-mockup.jpg” instead.

  • Alt Text: This is like the caption for your images. It’s not just for accessibility—it also helps search engines understand what your image is about.

  • Use Keywords in File Names: If you’re selling that trendy botanical print, name your image “botanical-print-mockup.jpg” instead of something vague.
