What is image publish preparation?
Image publish preparation is the workflow someone uses when they need the same source image prepared for several platforms or asset types at once. Pick a Product Listing Kit for marketplace photos (Amazon, Shopify, Etsy, catalog square) or a Website Brand Pack for favicon, app icons, Open Graph, logos and an HTML head snippet. Upload once, review the task preview and publish checks, then download a ZIP or individual files.
Targets at a glance
Each row pairs a target with the kind of rule it comes from. Requirement means the platform mandates it. Recommendation means the platform suggests it. Tool preset means the size is shipped by this tool. Archive means a delegated multi-file package.

Quick Answer
The Image Publish Preparation Center accepts one PNG, JPG or WebP upload and outputs up to twelve targets across two scenario kits. The Product Listing Kit covers Amazon Main Image, three Shopify shapes, Etsy and a catalog square. The Website Brand Pack covers favicon and app icon packages, Open Graph image, two website logo sizes and an HTML head snippet. Before generation, the task preview checklist and publish checks flag upscaling, letterboxing and background issues. After generation, download the full ZIP or individual successful files; use Retry failed only to re-run targets that did not succeed.
How it works
- 1 Pick a scenario. Listing kit, brand pack or custom target selection.
- 2 Review task list + checks. Upload your image and resolve publish checks.
- 3 Generate. Each target renders independently inside one ZIP with manifest.json.
- 4 Download. Full ZIP, individual files, or retry failed targets only.
Output contract
The ZIP contains a manifest.json file. Every successful entry records the
requested and actual width, height, format and background. Per-target failures do not block
the rest of the run; failed targets appear with "status": "failed"
and an error string.

Frequently asked questions
What are the scenario kits?
The page offers two one-click kits plus a custom mode. Product Listing Kit selects Amazon, three Shopify shapes, Etsy and a catalog square — six marketplace listing photos from one upload. Website Brand Pack selects the favicon package, app icon package, Open Graph image, two website logo sizes and an HTML head snippet. Custom keeps the legacy default (Amazon Main + Shopify Square) and lets you tick any combination of all twelve targets.
What is the task preview checklist?
Before you generate, the checklist lists every selected target with its output filename, use case, size, format, background rule, crop policy and rule kind (Requirement, Recommendation, Tool preset or Archive). It is a read-only contract summary so you can confirm the ZIP will contain exactly what you expect before spending processing time.
What are publish checks?
After you upload and pick targets, the page runs rule-based publish checks against your source image — no external AI. The verdict is Ready, Can generate with suggestions, or Must adjust. Checks flag upscaling, letterboxing, alpha on white backgrounds and oversized sources. One-click fixes can flatten transparency onto white or switch a target back to Keep Original when White would flatten alpha.
Can I download individual files instead of the full ZIP?
Yes. On the result step each successful target has its own Download button. The page extracts that entry from the ZIP in your browser — PNGs, nested favicon or app-icon ZIPs, and the HTML head snippet download by basename. The full ZIP download remains available when you want every file plus manifest.json in one archive.
What if some targets fail but others succeed?
Partial failures are isolated. Failed targets appear in manifest.json with a failed status and an error string; successful targets are still inside the ZIP. The result step never claims full success when every target failed. Use Retry failed only to re-run just the failed slugs with the same source file — no need to re-upload.
Which targets are available?
Twelve targets across listing and brand scenarios: Amazon Main Image, three Shopify shapes, Etsy listing photo, catalog square, favicon package, app icon package, Open Graph image, two website logo sizes and an HTML head snippet. E-commerce targets output individual PNGs; archive targets embed the same ZIPs as the dedicated Favicon and App Icon Generator pages.
Will output dimensions match what I selected?
Yes. Every successful image target is rendered at the documented pixel dimensions and manifest.json records both requested and actual width, height, format and background. If the two ever disagree the manifest surfaces the mismatch so you can verify the file before uploading to a marketplace or dropping assets into a project.
What file types can I upload?
PNG, JPG, JPEG and WebP up to 10 MB. The same extensions the single-target Amazon, Shopify and Etsy resizers accept. SVG is not supported on this page because marketplace and icon pipelines expect raster input. Publish checks validate format and dimensions before generation is allowed.
