Frequently asked questions
Do I need WordPress or Shopify to use the tool?
No. Extract the downloaded ZIP and open index.html in a current desktop browser. No installation, website or store connection is required.
Are my product images uploaded?
No. Image processing happens inside your browser. The application has no external image-upload or analytics function.
Which image formats are supported?
You can import JPEG, PNG and WebP files. Output can preserve each original file type or convert the batch to JPEG, PNG or WebP.
How does SKU renaming work?
The tool derives a starting SKU from the filename. You can edit every SKU, choose upper/lowercase, set sequence digits and build names using {sku}, {index} and {original} tokens.
Will my original images change?
No. The tool creates processed copies in a new ZIP. Always keep your originals and review output before importing it into a live store.
What does the license allow?
One purchase licenses one named user to prepare images for their own business and client catalog work. Redistribution, resale or sharing of the tool is not permitted.
Choose an image workflow before processing a batch
Consider a fictional supplier set containing a front view, back view and detail shot of one shirt. The goal is consistent presentation and traceable filenames. The example below explains the choices; it does not process images on this page.
Step 1: Decide whether to fit, crop or contain
Use fit when the full image should remain within your maximum dimensions. An exact centre crop can remove parts near the edges, so inspect it carefully. Contain is useful when the complete product should sit on a fixed-size canvas. Your destination’s image requirements determine the appropriate dimensions.
Step 2: Review the output format and quality
Choose the supported output format for your destination, then process a small sample. Inspect fine details, edges and colour appearance before applying the same rules to the whole batch. A smaller file is useful only if the product remains clearly represented.
Step 3: Confirm each image’s SKU and sequence
For the fictional SKU SHIRT-001, review the detected SKU for all three images. Use the tool’s filename preview and supported tokens to create the intended sequence. Confirm the order before exporting; a filename alone does not guarantee how a store will order its gallery.
Step 4: Inspect the ZIP before uploading
Open representative output files and confirm dimensions, cropping, naming and readability. Keep your source images and the processed batch separate. Review destination-specific rules before uploading or linking images in a product CSV.
