Platform preparation & upload checks

Prepare for platform

Selecting a platform applies preparation settings, never changes your SKU or naming template, and does not certify a listing. Re-select to reapply after customization. Checks continue to use the selected platform.

Basic rules

Convert formatImage quality: 85

Square canvas gives every image identical dimensions, fitting the whole product with white padding. Original proportions only limits the long edge; dimensions may differ. Neither removes backgrounds.

Custom dimensions & naming

Do not enlarge source pixelsPlatform presets preserve native detail. A fixed canvas can still add large margins; inspect product occupancy. Turning enlargement on cannot repair a low-resolution source.

Resize

Long edge (px)Canvas ratio

Images keep their proportions. White padding fills fixed sizes and canvas ratios.

Rename templateAvailable: {name} {index} {sku} (Product ID) {variant_sku} {color} {size}. Set index start and padding below; type separators directly in the template.

Index startIndex digits

Numbering restarts per product (or per quick batch). The main image gets the starting number. Digits set minimum padding, not truncation.

Before exporting: assign products and variants below, resolve any errors, then confirm the filename mapping. Review product mapping

Save or restore a local draft

Keep your setup on this device

Save rules, filenames and SKU assignments locally, not image bytes. To restore, reselect the complete original file set. Matching uses name, size, type and modification time, not image content; review all restored assignments.

My SKU rules, CSV & store presets

Use your own SKU rules

Keep your existing product and variant codes. CSV and filename rules only prepare a preview; applying replaces the affected assignments and clears their main role and confirmation. Nothing is uploaded.

Escape unsafe path characters, preserve original SKU

Recommended: / becomes %2F, : becomes %3A and % becomes %25 in export names. Original identifiers stay in manifest.json. Case-only identity conflicts still need correction. Identifiers are limited to 80 UTF-8 bytes; control characters are not supported.

Import your own CSV layout

UTF-8 CSV only, up to 1 MB, 200 rows and 32 columns. Export XLSX as CSV first. Map filename and product columns; other fields are optional. If no image-type column is mapped, nonempty variant fields mean variant, otherwise shared. Filenames must match exactly and be unique. SKU cells are text: keep leading zeros when exporting from your spreadsheet.

Choose your CSV

Extract from structured filenames

Choose a literal delimiter and 1-based positions, joined by commas (for example 1,2,3). The extension is excluded. Blank optional positions are ignored. Example AB2026_BLK_XL_01.png: product 1, variant 1,2,3, color 2, size 3. All selected files must match. No appearance-based guessing.

Store presets on this device

Up to 10 named presets: image rules, column mapping and filename extraction only. No files, per-image assignments or images are saved. Loading never applies extraction or imports a CSV automatically. No account sync.

Reuse your setup on another device

Download a settings-only JSON backup, then import it on another browser. No pictures, filenames, per-image SKU assignments, ASINs or credentials are included. Imported names never overwrite existing stores. This is a manual transfer, not cloud sync.

Import preset backup

Assign products and variants

Supplier filenames do not identify a product reliably. Enter a Product ID to group images, and an optional Variant SKU for each sellable option. Nothing is assigned from image appearance.

Add supplier images to start assigning products.

Frequently asked questions

Are my images uploaded to a server?

No. Decoding, resizing, encoding and ZIP packaging all happen in your browser. Images stay on your device.

How many images can I select?

Up to 200 per selection. The free monthly allowance is 50 successfully processed images, so each run must fit your remaining allowance.

Is it free?

You can process 50 images per month for free. Once used up, wait for next month. Paid plans are coming soon. Successful images count even if you cancel; failures do not.

Which formats are supported?

Input: JPG, PNG, WebP and AVIF where your browser can decode them. Output: JPG, PNG or WebP. HEIC is not supported.

What is variant grouping?

You enter the product SKU and confirm each image’s color / size or mark it as a shared image. Filename suggestions are not automatic assignments. Product folders keep identical variants from different products separate. ZIP folders do not automatically bind store variants.

Can white background remove a complex background?

This version normalizes light, neutral backgrounds connected to the edges. Use our AI Background Remover for complex backgrounds.

What you will have

An organized ZIP of converted, resized and renamed product images, with export mappings and reports. Light-background normalization is optional; this batch workflow does not remove complex backgrounds or bind store variants.

Frequently asked questions

Can I prepare a batch of product images?

This workflow accepts up to 200 selected images, with 50 successfully processed images free per month. It creates an organized ZIP locally. You review SKU and variant assignments; ZIP folders do not automatically bind store variants.

Which background should I use?

Use the marketplace or brand guidelines for your listing. A simple white or neutral background is usually the most flexible starting point.
