If listings were rejected for dimensions, aspect ratio, or file size—or zoom looks soft—you usually need a consistent frame and lighter bytes. Here is a practical fix path with The Bulk Toolkit.
1. Confirm the target.Open your marketplace's current image requirements (minimum and recommended pixels, aspect ratio, max file size). Our platform hub links to size guides for Amazon, Shopify, Etsy, Flipkart, Meesho, and more.
2. Resize in one batch. Use Bulk Resize with the matching preset (or custom width and height) so every SKU uses the same canvas before upload.
3. Compress if the portal caps megabytes. Run Bulk Compress with High Quality first; step down only if you are still over the limit. See bulk image compressor for a short overview.
4. Follow a channel workflow. For a ordered checklist (especially Amazon), use Amazon seller workflow or the Shopify / Flipkart / Meesho flows from the platform hub.
