How marketplace image resizer works
Upload your product photo
One source image is enough — the highest resolution version you have gives the best results.
Pick your marketplaces
Select Amazon, Shopify, Etsy, eBay, Instagram, or set a custom dimension. Select as many as you need at once.
Download every size
Smart cropping keeps your product centred and complete in every aspect ratio — download the full set in one click.
Smart crop keeps the product whole
Naive resizing chops products in half. The AI detects your product's bounding box and crops around it, keeping it centred with correct margins in every ratio.
Exact marketplace compliance
Amazon's 1000px zoom minimum, Etsy's 2000px shortest side, Instagram's 4:5 feed ratio — presets encode each platform's current requirements so listings never get flagged.
Extend, don't stretch
When a ratio needs more canvas, AI extends the background naturally instead of stretching or squashing the photo — no distorted products, no letterboxing.

Your complete AI product photo studio
Marketplace Image Resizer is one tool of twenty. Sellable turns one plain product photo into a full campaign — studio backgrounds, lifestyle scenes, on-model shots, and UGC-style videos — all in seconds.
We sell on four channels and used to keep four image sets. Now one master photo exports to every spec automatically — one source of truth, zero rejected listings.
Frequently asked questions
Which marketplace presets are included?
Amazon main image, Shopify square, eBay, Etsy, Instagram feed and story, Google Shopping, and Facebook catalog — plus fully custom dimensions.
How does smart cropping work?
The AI detects the product in the frame and crops around it, keeping it centred with appropriate margins — so switching from square to 4:5 never cuts off your product.
What if the new ratio needs a wider canvas?
The background is extended with AI-generated content that matches the original scene — no stretching, squashing, or white bars.
Does resizing reduce quality?
No — output is generated at the target resolution up to 4K. Upscaling is applied when the target is larger than the source.
Can I resize a whole catalogue at once?
Yes — combine the resizer with batch processing to export your entire catalogue to every marketplace spec in one run.
Is there a free trial?
Yes — sign up free and resize photos with your starter credits. No credit card required.
