Batch Rename Images
Preview and rename up to 30 image files with a prefix, suffix, sequence number, optional date, and find-and-replace rule. The original bytes are placed into a ZIP under safe, unique names, so image quality, dimensions, format, metadata, and transparency are not recompressed.

Built for dependable batch work
This page changes filenames inside a downloaded archive. Browsers cannot rename files in their original folders, and the tool does not alter image contents. It protects extensions, removes unsafe path characters, resolves duplicate outputs, and shows the complete mapping before packaging.
No image recompression
Built for repeatable image workflows with clear output evidence.
Predictable sequence numbering
Your selected files remain in the current browser session.
Duplicate-name protection
Each queue row reports its own result without blocking valid files.
Original extension preserved
Downloadable output uses names and formats that match the generated bytes.
How to use Batch Rename Images
A four-step workflow keeps the original files separate from generated output.

What this batch tool does
This page changes filenames inside a downloaded archive. Browsers cannot rename files in their original folders, and the tool does not alter image contents. It protects extensions, removes unsafe path characters, resolves duplicate outputs, and shows the complete mapping before packaging. Every item is handled independently, so one unsupported or damaged file does not erase successful work from the rest of the queue.
- No image recompression
- Predictable sequence numbering
- Duplicate-name protection
- Original extension preserved
Batch Rename Images guide
Use these checks to get output that fits the destination rather than stopping at a successful download.
Build a filename pattern that sorts well
A useful batch name usually combines a stable project term with a padded sequence, such as product-front-001.jpg. Padding keeps alphabetical file lists in numeric order. Prefixes are best for collection or campaign names, while suffixes can identify a variant, revision, language, or channel. The optional date uses an unambiguous year-month-day form so files continue to sort chronologically.
Use find and replace for controlled cleanup
Find and replace can remove camera prefixes, old campaign codes, spaces, or repeated words before the new prefix and suffix are applied. The preview is the authority: check every output rather than assuming all source names follow the same pattern. If a replacement would create an empty base, the tool substitutes a safe image name. Characters that can form paths or fail on common file systems are normalized.
Keep extension and bytes aligned
The tool retains each original extension and copies the source bytes directly into the ZIP. It does not pretend that a renamed extension converts a file. A JPEG remains JPEG and a PNG remains PNG. For format changes, use a conversion tool that encodes and validates new bytes. This separation is important because incorrect extensions can confuse content management systems, browsers, and automated asset pipelines.
Treat the downloaded ZIP as a review step
Browser security prevents a website from rewriting filenames in an existing local folder. The ZIP therefore becomes a safe staging package. Compare the mapping shown on the page with the archive, scan for unexpected duplicate suffixes, and test how downstream systems handle capitalization. Keep an untouched source set until links, references, and manifests have been updated to the new names.
Batch quality checklist
Start with copies when the source collection is valuable, and keep filenames that let you trace every result back to its original. Test a small representative set before processing the full queue, including the largest file, a transparent image, a portrait, and a landscape image. After processing, compare pixel dimensions, format, file size, transparency, text sharpness, edge detail, and color in the actual destination. A successful browser status confirms that this tool completed and verified its expected output structure; it does not replace editorial review or the receiving platform’s rules. Keep the downloaded ZIP or CSV with the settings used for the run, then record exceptions that need individual treatment. For publishing workflows, also check descriptive alternative text, rights, consent, naming conventions, backup policy, and cache behavior. These steps make a repeatable batch safer than treating every completed download as automatically ready for production.
សំណួរដែលគេសួរញឹកញាប់
Practical answers about formats, privacy, quality, and browser behavior.
Does renaming reduce image quality?
No. Original file bytes are copied into the ZIP without decoding or re-encoding.
Can the page rename files in my existing folder?
No. Browser security prevents that; the renamed copies are provided in a downloaded ZIP.
Are original extensions preserved?
Yes. The tool changes the base filename and retains the original extension rather than faking conversion.
What happens to duplicate output names?
A deterministic numeric suffix is added so no file silently replaces another inside the archive.
Can I start numbering at a custom value?
Yes. Set the starting number and the minimum number of padded digits.
Are the selected files uploaded?
No. Filename planning and ZIP packaging happen in the active browser.
Can I review names before download?
Yes. Every source-to-output mapping appears in the queue before and after packaging.
