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.

专为可靠的批量工作而打造
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

这个批处理工具的作用
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
使用这些检查来获取适合目标的输出，而不是在成功下载时停止。
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.
批次质量检查表
当源集合很有价值时，从副本开始，并保留可让您将每个结果追溯到其原始结果的文件名。在处理整个队列之前测试一个小的代表性集，包括最大的文件、透明图像、肖像和风景图像。处理后，比较实际目标中的像素尺寸、格式、文件大小、透明度、文本清晰度、边缘细节和颜色。成功的浏览器状态确认该工具已完成并验证了其预期的输出结构；它不能取代编辑审查或接收平台的规则。保留下载的 ZIP 或 CSV 以及用于运行的设置，然后记录需要单独处理的异常。对于发布工作流程，还要检查描述性替代文本、权限、同意、命名约定、备份策略和缓存行为。这些步骤使可重复的批次比将每个已完成的下载视为自动准备生产更安全。
常见问题
有关格式、隐私、质量和浏览器行为的实用答案。
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.
