Sample compliance report
See what pass/fail looks like before upload, then fix each item with FreeMake tools.
Amazon — Needs fixes
Resize to 1000×1000+, add white background, convert to JPEG, then re-check.
How to Check E-commerce Image Compliance Locally
Upload errors waste hours—wrong pixels, oversized files, or off-white backgrounds fail after you think you are done. FreeMake compliance checker analyzes images in your browser against common Amazon and Shopify rules with no server upload.
Upload candidate listing images
Add the hero or gallery files you plan to submit. Checking before bulk upload prevents partial catalog rejections that stall launches.
Select marketplace or general preset
Presets cover frequent Amazon dimension, aspect ratio, file-size, and white-background hints. Always cross-check official Seller Central docs—rules change by category.
Read pass/fail indicators and fixes
Failed checks link to resize, compress, and white-background tools. Fix issues in order: dimensions, background, then file size.
Re-check after edits
Run the checker again on exported files before final upload. A green pass reduces surprise suppressions on main-image slots.
Why Pre-Flight Checks Save Seller Time
Marketplaces enforce image rules silently until listings go live or ads disapprove. Local validation catches problems while assets are still editable on your machine.
Stop launch-day upload fire drills
Batch validate fifty SKUs before touching Seller Central. Fix patterns once—resize template, compress preset—then apply across the catalog.
Protect main-image placement
Hero image violations can suppress buy-box visibility. Compliance hints flag off-white backgrounds and extreme aspect ratios early.
Private analysis of supplier packs
Checker runs locally—wholesale imagery and exclusivity deals are not sent to third-party audit servers.
FreeMake vs Manual Checklists & Seller Central Preview
Spreadsheets and PDF guides go stale; Seller Central only reacts after upload. FreeMake gives instant local feedback tied to fix tools.
| Feature | FreeMake | Manual checklist | Upload-then-fail |
|---|---|---|---|
| Instant local analysis | Yes | Slow manual | After upload only |
| Dimension & file-size checks | Yes | If you measure | Error message |
| White background hints | Yes | Eyeball only | Sometimes vague |
| Links to fix tools | Resize, compress, white-bg | None | None |
| No image upload | Yes | N/A | Required |
What the Checker Evaluates
Typical checks include minimum/maximum dimensions, aspect ratio bands, file size in MB, and whether backgrounds appear pure white for hero-image rules. Results are advisory—official marketplace documentation remains the source of truth.
Supported inputs are standard listing formats (JPG, PNG, WebP). After fixes, export JPG for most Amazon heroes and PNG when transparency is required for secondary creative assets.
- Dimensions — longest side and square ratio warnings
- File size — flags before 5–10 MB upload caps
- White background — RGB proximity for main-image policy
- Workflow — fix with resize → white-bg → compress → re-check
Compliance checker FAQ
This tool diagnoses issues—it does not edit images. Read what is and is not checked.
- Which platforms are supported?
Amazon, Shopify, eBay, Etsy, and Instagram—common size, ratio, weight, and format rules.
Marketplace rules change. Use this as a pre-upload checklist, not legal advice. Confirm in official seller help centers.
- Will it fix my image automatically?
No. You get pass/fail checks with reasons and links to FreeMake fix tools (resize, compress, white background).
- Why does Amazon check ask for 1:1?
Amazon main images are often required to be square (1:1) with at least 1000px on the long edge.
- Batch check? Signup required?
One image per run. Free, no signup. Files stay on your device.
- If I pass, am I guaranteed approval?
Not necessarily—content, category, and text policies are separate. This covers common technical image specs only.
- Which marketplaces are supported?
Presets cover common Amazon, Shopify, and general e-commerce requirements. Always verify latest official docs.
- What if my image fails a check?
Use resize, compress, or white background tools to fix issues, then re-check.
- Are photos uploaded?
No—analysis runs locally in your browser.
Fix issues and finalize your listing
If your image failed any checks, use this repair workflow:
- Image Resizer
Resize to fix dimension and aspect-ratio violations.
- Image Compressor
Compress when file size exceeds marketplace limits.
- White Background
Add a pure white background for Amazon main-image rules.
Result: all flagged issues resolved — re-check and submit with confidence.
