Will my photo be cropped?

Related Use Cases

How to Resize Product Images for Multiple Online Marketplaces

Each online marketplace has different image dimension requirements — Amazon wants 2000×2000, eBay prefers 1600×1600, Etsy has its own specs, and social media platforms each need different sizes for product announcements. Manually resizing the same product photo 5+ times in Photoshop for each platform is repetitive, time-consuming, and easy to get wrong.

How to Resize Images for Instagram Posts and Stories

Instagram requires specific image dimensions — 1080×1080 for feed posts, 1080×1920 for stories, and 1080×1350 for portrait posts. Uploading the wrong size means your content gets cropped awkwardly, cutting off important elements, or appears lower quality than it should. You need quick, precise resizing without opening Photoshop.
