The best image size depends on where you upload it. Instagram needs square, portrait, and vertical images. Facebook needs feed, cover, and link preview images. YouTube needs thumbnails and banners. Shopify needs clear product images that load fast.
Before uploading, resize your image, choose the right format, and compress image files so they stay sharp without becoming too heavy.
Use 1080×1080 for square Instagram and Facebook posts, 1080×1920 for Stories, Reels, and vertical content, 1200×630 for link previews, 1280×720 for YouTube thumbnails, 2560×1440 for YouTube banners, and 2048×2048 for Shopify product images. Instagram says high-resolution photos are sized to 1080 pixels wide, and Shopify’s 2026 image guide recommends 2048×2048 for square product images.
Best Size Quick Guide for 2026
- Use 1080×1080 when you need a clean square image for Instagram or Facebook.

Use Lovely Imgs Before You Upload
Use Lovely Imgs before publishing images on Instagram, Facebook, YouTube, or Shopify. It helps you resize, convert, and optimize images online without complicated software.
A strong workflow is simple. First use the image resizer to match the platform size. Then use the right image converter when the format is not ideal. Use PNG to JPG when transparency is not needed. Use JPG to WebP when you need smaller website images. Finally, use compress image before uploading large files.
This makes your images easier to upload, faster to load, and cleaner on mobile screens.
Step-by-Step Guide: How to Prepare Images for Any Platform
Step 1: Choose the Platform
Do not resize every image to the same size. Start with the platform first.
Instagram needs feed, portrait, and vertical formats. Facebook needs feed images, link preview graphics, and covers. YouTube needs thumbnails and banners. Shopify needs product images, collection images, and store banners.
When you choose the platform first, you avoid bad cropping and blurry uploads.
Step 2: Resize the Image
Resize your image to the correct dimensions before uploading. A platform may compress or crop the image if the size is too large, too small, or the wrong shape.
For example, a YouTube thumbnail should stay in a 16:9 shape. A Shopify product image usually works better as a square. A Story or Reel image should be vertical.
Use the Lovely Imgs image resizer to create the correct version before publishing.
Step 3: Choose the Right Format
Use JPG for photos, product images, banners, and social media graphics where transparency is not needed.
Use PNG for logos, screenshots, icons, graphics with text, and transparent backgrounds.
Use WebP for modern website and ecommerce images because it can reduce file size while keeping good visual quality.
Use GIF only for simple animation. For normal static images, JPG, PNG, or WebP is usually better.
Step 4: Convert the Image if Needed
If your file is PNG but transparency is not needed, convert it with the PNG to JPG converter. This is useful for product photos, social posts, blog graphics, and large screenshots.
If your image will be used on a website or Shopify store, convert JPG to WebP with the JPG to WebP converter. WebP can help reduce image weight for faster loading.

Step 5: Compress Before Uploading
Large image files can slow websites and make uploads harder. After resizing and converting, use the compress image tool to reduce the file size.
The goal is not to make the smallest file possible. The goal is to keep the image clear while making it light enough for fast upload and faster page loading.

Step 6: Preview on Mobile
Most people view social media and Shopify stores on mobile. Always check the final image on a phone.
Look at faces, product edges, logos, text, and important details. If the text is too close to the edge, it may get cropped. If the image is too compressed, it may look soft. If the file is too heavy, it may slow down the page.
What Happens When Platforms Resize Images?
Platforms resize images to fit their own display areas. Instagram may reduce image width. Facebook may crop covers differently on desktop and mobile. YouTube shows thumbnails in many places, including search, suggested videos, and home feeds. Shopify themes may show product images in product pages, collection grids, carts, and recommendations.
This is why the uploaded image should already be close to the correct size. A correctly prepared image gives the platform less work to do. It also protects quality, cropping, and file size.
Instagram Image Sizes in 2026
For Instagram square posts, use 1080×1080 pixels. For portrait posts, use 1080×1350 pixels. For landscape posts, use 1080×566 pixels. For Stories and Reels, use 1080×1920 pixels. Buffer’s 2026 Instagram size guide lists these feed, Story, and Reel dimensions, and Instagram’s own help page says high-resolution photos are sized down to 1080 pixels wide.
Use 1080×1080 when you want a clean square post. Use 1080×1350 when you want more space in the feed. Use 1080×1920 when the image is for Stories, Reels, or full-screen mobile content.
Before uploading to Instagram, resize the image and compress it carefully. If your image becomes blurry after posting, read compress images for Instagram without blurry results.
For Instagram photos, JPG usually works well. For text-heavy graphics, PNG may keep edges cleaner. For website reuse, WebP can be better after uploading the image to your own site.
Facebook Image Sizes in 2026
For Facebook square posts, use 1080×1080 pixels. For link preview images, use 1200×630 pixels. For Facebook cover images, use a wide image around 820×360 pixels and keep important content near the center because desktop and mobile crops can differ. Meta’s help page gives Facebook Page profile and cover photo guidance, while current cover size guides explain that desktop and mobile display areas are not the same.
Use 1080×1080 for brand posts, offers, testimonials, and announcements. Use 1200×630 for blog previews, landing page previews, and shared article images.
If your Facebook graphic has text or a logo, do not place it too close to the edge. Keep the main message centered.
Before uploading, use PNG to JPG when your design does not need transparency. Then use compress image to reduce file size while keeping the post clear.
YouTube Image Sizes in 2026
For YouTube thumbnails, use 1280×720 pixels in a 16:9 shape. This is the practical creator standard for thumbnails and is widely used because it fits YouTube previews well. YouTube’s help documentation confirms that custom thumbnails are uploaded from an image file, and current thumbnail size guides continue to recommend 1280×720 with a 16:9 layout.
For YouTube channel banners, use 2560×1440 pixels. Keep the channel name, logo, and important text in the center because banners display differently on TV, desktop, tablet, and mobile.
Use strong contrast for thumbnails. Make faces, products, and main text easy to see at a small size. Avoid small text because many people will see the thumbnail on mobile.
Before uploading a YouTube thumbnail, resize it, check the text, and compress it. JPG is useful for photo-based thumbnails. PNG is useful for thumbnails with sharp text or graphics.
Shopify Image Sizes in 2026
For Shopify product images, use 2048×2048 pixels. Shopify’s 2026 image size guide says Shopify supports uploads up to 5000×5000 pixels with a file size up to 20 MB, and it recommends 2048×2048 pixels for square product images.
For Shopify collection images, 1024×1024 pixels is a practical starting point. For hero and banner images, 1920×1080 pixels often works well, but your final crop depends on the theme. Photoroom’s 2026 Shopify size guide also lists 2048×2048 for product images, 1920×1080 for hero images, and 1024×1024 for collection images.
Keep product image ratios consistent. A store with mixed image sizes can look unprofessional on collection pages. Use the same crop style for product photos whenever possible.
For Shopify, file size matters as much as dimensions. A 2048×2048 image can still be too heavy if it is not compressed. Use PNG to JPG when you do not need transparency, JPG to WebP for faster store images, and compress image before uploading.

Instagram vs Facebook vs YouTube vs Shopify: Which Size Should You Use?
Use Instagram sizes when the image is designed for mobile attention. Square and portrait images work well for the feed. Vertical images work best for Stories and Reels.
Use Facebook sizes when the image will appear as a post, cover, or link preview. Square posts are flexible, but link preview images need a wide shape.
Use YouTube sizes when the image needs to attract clicks. Thumbnails should be wide and clear. Banners should be large and centered.
Use Shopify sizes when the image needs to sell a product. Product images should be clear, consistent, and compressed for fast loading.
The best image size is the one that matches the placement without forcing the platform to crop or stretch it.
Format Decision: JPG, PNG, WebP or GIF?
Use JPG for photos, product images, social media posts, and banners where smaller file size matters.
Use PNG for transparent images, screenshots, logos, icons, and graphics with sharp text.
Use WebP for modern websites, blogs, and Shopify stores when speed is important. WebP is useful when you want smaller files with strong visual quality.
Use GIF only for simple animation. Do not use GIF for normal product photos, thumbnails, or detailed graphics.
If you are not sure which format to use, start with the article on what is WebP image format, then use the right Lovely Imgs image converter for your final upload.
Benefits of Using the Right Image Size
Correct image sizes reduce cropping problems. The face, product, logo, headline, and important details stay inside the visible area.
Correct sizes improve image quality. Small images can look blurry when stretched. Oversized images may be compressed harder by platforms.
Correct sizing improves file size. A resized and compressed image uploads faster and loads better on websites.
Correct sizing also saves time. Instead of fixing one image after it is cropped or rejected, you can create the right version before upload.
Conclusion
