Amazon Product Image File Format Requirements: Accepted Types and How to Fix Rejected Files
Amazon only accepts four image extensions—JPEG (.jpg), TIFF (.tif), PNG (.png) and GIF (.gif). Files with other extensions (e.g., .heic, .webp, .bmp) are instantly rejected, as seen when 30 HEIC images blocked a batch of 150. Converting to an accepted format and re‑checking the extension resolves the issue.
Overview
Amazon’s marketplace only accepts four specific image file types for product listings. Files that use any other extension are automatically blocked, which can stall a listing’s activation. Knowing the exact formats that Amazon permits and how to convert non‑compliant files helps sellers keep their catalog moving without interruption.
Key Points
- Supported extensions — Amazon allows JPEG (.jpg), TIFF (.tif), PNG (.png) and GIF (.gif); JPEG is the default recommendation for most products.
- Case‑insensitive handling — Both upper‑case and lower‑case extensions work, so .JPG and .jpg are treated identically.
- Instant rejection — Uploads that contain an unrecognized extension are denied on the spot, preventing the product from going live.
- Quick format check — Right‑clicking a file and selecting “Properties” (Windows) or “Get Info” (Mac) reveals the true file type before you submit it.
- Conversion requirement — Images saved as BMP, WEBP, HEIC, RAW or any other unsupported type must be re‑saved in one of the four accepted formats.
- Rename ≠ conversion – Changing a file name from .bmp to .jpg does not alter the underlying format; Amazon’s system will still reject it.
How to Verify and Convert Image Files
- Inspect the file type — Open the file’s properties (Windows) or Get Info (Mac) to confirm the extension; for example, a photo saved as “shoe.png” will display “PNG image” in the details pane.
- Identify unsupported formats — If the details show BMP, HEIC, WEBP, RAW, or any format outside the four approved types, mark the file for conversion; e.g., a smartphone picture listed as “dress.heic” must be changed.
- Choose a conversion tool — Use a desktop editor such as Photoshop, the free program GIMP, or an online converter like CloudConvert; open the original file and select “Save As” JPEG at high quality, producing “dress.jpg”.
- Confirm the new extension — After saving, repeat step 1 to ensure the file now reads “JPEG image”; this double‑check prevents accidental mismatches.
Analysis & Recommendations
Why This Matters
A rejected batch can delay a product launch by days, as 30 HEIC files halted a 150‑image upload. Ensuring images are in JPEG, TIFF, PNG or GIF eliminates rework, speeds go‑live, and avoids manual re‑uploads.
Key Takeaways
- Amazon permits exactly four extensions: .jpg, .tif, .png, .gif.
- Extension handling is case‑insensitive; .JPG works the same as .jpg.
- Renaming a file (e.g., .bmp to .jpg) does not change its format; Amazon still rejects it.
- Bulk‑conversion tools like IrfanView batch mode can convert dozens of files, preventing delays such as the 30‑file HEIC rejection.
Recommended Actions
- →In Windows right‑click > Properties (or Mac Get Info) to confirm each image is .jpg, .tif, .png or .gif before uploading in Seller Central.
- →Convert any unsupported files (BMP, WEBP, HEIC, RAW) to JPEG/TIFF/PNG/GIF using Photoshop, GIMP or CloudConvert, then re‑verify the extension.
- →For large catalogs, run IrfanView’s batch conversion (File > Batch Conversion) and re‑upload via Seller Central > Inventory > Add Products via Upload.
