Bulk File Renaming Tool: Naming Images and PDFs from ZIP to ZIP in an SEO-Friendly Way

What is the Bulk File Renaming Tool?

This tool is designed to rename hundreds/dynamic files in the hands of agencies and marketplace sellers (especially images images and PDFs) at once, in a rule-based and SEO compliant manner, packaging them with the ZIP import → ZIP export flow. The reason for the proliferation of similar “online bulk file renamer / bulk rename images” tools is precisely this need: many files, one standard, quick output. 

What problem does it solve

• Bulk file renaming / batch rename / bulk rename: renames hundreds of files in a single operation.
• Bulk image renaming: names images such as JPG/PNG/WebP according to e-commerce standards and produces a “Download All (.zip)” output.
• Bulk PDF renaming: organizes PDFs such as catalogs, technical sheets, certificates, size charts with the same rules (e.g., match with barcode).
• From ZIP to ZIP (zipten zipe): the user uploads a single ZIP; the tool downloads the renamed files as a single ZIP (ideal for agency delivery).

Naming logic (template/pattern template)

There is a template naming system at the center. Example templates:

• {product-name}-{barcode}-{variant}
• {brand}-{product-name}-{color}-{size}-{sku}
• {category}-{product-name}-{serialNo} (numbering automatic / adding serial number)

Rules:

• slug creation: Corrects Turkish characters (ç,ğ,ı,ö,ş,ü), makes spaces into hyphens, converts to lowercase, cleans unnecessary symbols (SEO compliant file name / image seo filename).
• adding prefix / suffix: adds “korayspor-” to the beginning, “-front/-back/-detail” to the end.
• bulk find replace file name: “_” → “-”, “copy” → “”, “(1)” → “”.
• resolving same name conflicts: if the same name appears, it automatically adds -01, -02 or requires variant/serialNo.

“Product name + barcode + variant” flow (gold for marketplace sellers)

The real value of this tool lies in its fit to the real world of product operations:

• file naming with barcode / naming with SKU: The barcode/SKU is captured in the file name or the user uploads a “matching table” (manifest csv / Excel logic): barcode → product name → variant (color size variant).
• Standardizes the arrangement of “single product + multiple variants + multiple angles” in scenarios such as Trendyol product images / Hepsiburada product images / Amazon product image naming.
• Delivery package on the agency side: each product comes with a folder + file names adhere to the same standard (option to preserve folder structure).

SEO aspect (realistic, useful)

File naming alone does not create miracles; but especially since in systems like WordPress/WooCommerce/Shopify, the visual URL is generated from the file name, regular and descriptive naming provides practical benefits. In the WordPress ecosystem, the topic of “renaming image/media files” is directly addressed in the context of SEO. 

Therefore, the tool:

• applies SEO compatible visual name standard (short, descriptive, hyphenated, consistent).
• optionally adds “alt text and file name” output to the manifest csv (does not embed in content; provides ready text to the user).

Control/preview and reporting

• Preview screen: old name → new name (rename log report).
• Error catching: missing barcode, invalid character, overly long name, conflict.
• Output: renamed ZIP + manifest.csv (file list, product name, barcode, variant, order, note field).

Privacy and performance note

The strong approach of such tools is to perform the operation locally in the browser (without file upload) or at least process “without storing files” if possible. There are examples positioned in the market like “local method, files are not uploaded”. 

If you want, I can also extract the UI flow of this tool according to the Tools1984 standard (ZIP upload → match → select rule → preview → download ZIP) and rule sets directly to productize in the next step.
