Image tools / practical guide
Match product photos to a SKU CSV, preview safe filenames and export a ZIP with a mapping report.
A practical starting example
Match SKU photos without losing leading zeros
For a photo named mug-front.jpg and SKU 00124, use a CSV row mapping that filename to the text value 00124. Preview every proposed name. If two photos would produce the same name, resolve that conflict before exporting. Keep the mapping report beside the ZIP.

How to use Bulk Image Renamer
- Prepare a copy of the input. Supported inputs: JPG, PNG, WebP, HEIC, AVIF, GIF.
- Choose the operation and review the controls below before running the sample.
- Run the tool, then inspect the new output before using it.
Prepare the input
Use the controls described in the application. Supported inputs: JPG, PNG, WebP, HEIC, AVIF, GIF.
Supported input and output scope: JPG, PNG, WebP, HEIC, AVIF, GIF
Review the available controls
Choose a filename pattern using {sku}, {name} or {index}. SKU mapping uses a CSV with filename and sku headers. Check for missing mappings and name collisions before downloading.
How to decide whether the result is useful
Export your spreadsheet as UTF-8 CSV with filename and sku headers. Keep SKUs as text to preserve leading zeros.
- Compare the output with the unchanged source.
- Check the destination requirement before copying, downloading or uploading it.
- Open the downloaded file in the receiving application and check its actual type, size and contents.
- Use a second representative sample if the first does not cover the difficult part of your input.
Limitations and troubleshooting
Renaming preserves the original bytes and extension. CSV mappings must match every selected filename; duplicate output names are blocked.
If the output does not match your intention
Return to the original copy, review the selected input and controls, and repeat with a smaller sample. If the embedded view is unavailable, use the direct tool link at the top of this page. Browser support and device memory can affect file-based workflows.
Questions about this tool
What should I check first?
Export your spreadsheet as UTF-8 CSV with filename and sku headers. Keep SKUs as text to preserve leading zeros.
Can I use the tool from this guide?
The main button opens the working tool on its Tabaix subdomain. An optional embedded view may be added to this guide; the direct link remains available for larger screens, downloads or browser compatibility.
What should I keep before changing the input?
Keep an unchanged source and record any controls you chose. That gives you a comparison point and lets you repeat the task without replacing your original.
