Batch Image Renamer
Rename image files with numbered patterns in a ZIP
Batch Image Renamer — what it does
Rename a whole image set to a clean numbered pattern: set a prefix, an optional suffix, the starting number and how many digits to pad to, and every file is written into a ZIP in the order you selected it. Useful whenever camera-generated names like DSC_0431 need to become something a human or an import script can read.
When this tool helps
- Preparing a photo delivery for a client where files must appear in shooting order, not alphabetical order.
- Matching an image folder to an e-commerce import template that expects sku-01.jpg, sku-02.jpg and so on.
- Renaming screenshots into a documented sequence before dropping them into a manual or report.
How to use it
- Choose the image files to rename.
- Enter a filename prefix and an optional suffix.
- Set the starting number and the number of digits.
- Download the renamed images as a ZIP.
Accuracy, limits, and good practice
- Two or three padding digits keeps files sorting correctly past ten and a hundred, which one digit will not.
- Selection order determines numbering, so sort the folder the way you want the sequence to run before selecting.
- This changes names only. Dimensions, format and image quality are untouched, so use the resizer or compressor for those.
Frequently asked questions
Does it keep the original extension?
Yes. Each file keeps its own extension, so a mixed set of JPG and PNG images stays valid after renaming.
Can I start numbering from something other than 1?
Yes. Set any starting number — handy when you are adding a second batch to an existing numbered set.
Why a ZIP instead of renaming in place?
A web page cannot modify files on your disk. The ZIP is the browser's only safe way to hand back a whole renamed set.

批量圖片重新命名能做什麼
把整組圖片改成乾淨的編號規則：設定前綴、可選後綴、起始號碼與補零位數，所有檔案就會依你選取的順序寫入 ZIP。當 DSC_0431 這類相機檔名需要變成人或匯入腳本看得懂的名稱時特別好用。
什麼時候用得上
- 交付客戶照片時，要求檔案依拍攝順序而非字母順序排列。
- 配合電商匯入範本，需要 sku-01.jpg、sku-02.jpg 這種命名的圖片資料夾。
- 把截圖整理成有紀錄的序列，再放進說明手冊或報告。
使用步驟
- 選擇要重新命名的圖片檔。
- 輸入檔名前綴與可選的後綴。
- 設定起始號碼與編號位數。
- 下載重新命名後的 ZIP。
精確度、限制與實務建議
- 補到兩、三位數才能在超過十張、百張後維持正確排序，只用一位數會亂序。
- 編號依選取順序決定，請先把資料夾排成你要的順序再選檔。
- 此工具只改名稱，尺寸、格式與畫質完全不動，這些需求請用縮放或壓縮工具。
常見問題
會保留原本的副檔名嗎？
會。每個檔案沿用自己的副檔名，因此 JPG 與 PNG 混合的檔案組在改名後仍然有效。
可以不從 1 開始編號嗎？
可以，起始號碼任意設定，要把第二批接續到既有編號組時很方便。
為什麼是輸出 ZIP，而不是直接改名？
網頁無法修改你硬碟上的檔案，ZIP 是瀏覽器唯一能安全交回整組改名檔案的方式。
