Resize Images for eBay, Instagram, Amazon and Every Platform in One Click

Every platform has its own image size requirements. eBay wants 1600×1600 for the zoom feature to work. Instagram recommends 1080×1350 for portrait posts that take up maximum feed space. Amazon requires at least 2000×2000 for product listings. If you sell on multiple platforms or manage social media accounts, you already know how tedious it is to look up dimensions, open a desktop editor, type in pixel values, and export each version individually.

FixMyFoto's resize tool has built in presets for every major platform. You drop your image, click one button, and get the exact dimensions that platform requires. No Googling pixel sizes. No mental math. No Photoshop. And because everything processes in your browser, your product photos and content never touch a server.

Every Preset, Verified for 2026

We researched the official documentation for each platform and verified every dimension. These presets are grouped into three categories: social media, ecommerce, and standard sizes.

Why eBay Sellers Need 1600×1600

eBay's search algorithm favors listings with high quality images, and the zoom feature that buyers rely on only activates when images are at least 1600 pixels on the longest side. Listings without zoom capable images get fewer clicks and lower placement in search results. The 1600×1600 square format also uses the maximum available space in eBay's browse grid, making your product stand out against competitors using smaller images.

If you shoot product photos on your phone, they are usually 4000×3000 or similar. Uploading that directly to eBay means the platform compresses and crops it unpredictably. Resizing to exactly 1600×1600 beforehand gives you full control over how the image appears and ensures the zoom feature works perfectly.

Instagram's 2025 Grid Change and What It Means

Instagram shifted from a square grid to a taller 3:4 preview format in 2025. This means portrait oriented posts at 1080×1350 now get more real estate on profile grids and in the feed compared to square posts. The FixMyFoto resize tool includes both the classic 1080×1080 square and the newer 1080×1350 portrait preset so you can choose based on your content strategy.

For Stories and Reels, 1080×1920 remains the standard. This is the native 9:16 vertical format that fills the entire phone screen. Uploading at this exact size prevents Instagram from cropping or adding padding.

How the Resize Tool Preserves Quality

Resizing an image is not just about changing pixel dimensions. A bad resize algorithm produces blurry, pixelated results. FixMyFoto uses the browser's high quality Lanczos resampling via the Canvas API with imageSmoothingQuality set to "high". This is the same algorithm used in professional desktop editors like Photoshop.

For JPEG output, the tool defaults to 92% quality, which produces files that are visually indistinguishable from the original while keeping file sizes reasonable. PNG output is lossless. You can also use the scale slider to resize proportionally from 5% to 400% of the original, with the aspect ratio locked by default to prevent accidental stretching.
