For e-commerce sellers

One master photo. Every marketplace's cap, cleared.

Selling across Amazon, Etsy, eBay, Walmart, and your own store means juggling a different file size cap on every one. Compress once, list everywhere, no rejections.

Same zoom-in detail for fabric and stitching — a fraction of the file size Shopify stores and serves.

The problem

Every marketplace has its own idea of 'too big.'

Cross-listing the same product across channels means the same photo has to satisfy Amazon's 10 MB cap, Walmart's 5 MB cap, and Etsy's much tighter 1 MB limit — all at once, if you want one master image to work everywhere without rejections or re-edits. A photo straight from a product shoot easily runs 4–8 MB, which is fine for Amazon, borderline for Walmart, and an automatic problem for Etsy. Multiply that across a catalog of even a few dozen SKUs, and 'just resize it per platform' turns into a standing chore every time you add a new product or a new channel.

How it fits your workflow

Compress once, to the tightest cap you sell under.

01

Shoot or export your master product photo

At full resolution, the way you already do for your primary sales channel.

02

Drop the catalog folder into FastCompressor

Batch an entire product line at once, whether it's 10 SKUs or 1,000.

03

Compress under your tightest channel's cap

Set the quality slider so every image clears the smallest limit you sell under — usually Etsy's 1 MB — while keeping zoom-level product detail.

04

List the same file across every marketplace

No per-platform re-editing, no separate exports to manage as your channel mix grows.

Built for this, not everything

The features multi-channel sellers actually use.

Cross-platform

One export, every marketplace

Compress to fit the tightest cap in your channel mix, so the same file is valid on Amazon, Etsy, eBay, Walmart, and your own store.

Compliance-safe

Compression only, no composition changes

Shrinks file size without touching framing or background, so main images stay compliant with each platform's listing rules.

Catalog-scale

Batch a whole product line

Run an entire catalog in one pass instead of re-exporting images SKU by SKU as you expand to a new channel.

Zoom-safe quality

Keeps detail zoom features need

Tuned to stay sharp enough for Amazon's and Etsy's zoom viewers, not just 'small enough to upload.'

Why this matters for cross-listing
1 MB

The tightest cap in your channel mix sets the rule for all of it.

Etsy limits each listing photo to just 1 MB per file, while Walmart allows up to 5 MB and Amazon up to 10 MB. Sellers cross-listing across all three have to satisfy the strictest limit in the group, or maintain separate exports per platform — one more manual step for every SKU, on every channel, every time a product is added.

One export. Every marketplace cleared.

FastCompressor Pro removes batch limits and adds cap presets tuned for Amazon, Etsy, eBay, and Walmart, so your whole catalog stays compliant as you expand to new channels.
