How to use the Bulk Rename + Convert

  1. 1Upload the images in the order you want them numbered.
  2. 2Type a pattern such as product-{n:3} or {original}-thumb and set the start number.
  3. 3Optionally pick an output format to convert at the same time.
  4. 4Check the live name preview, then download the ZIP.

Rename hundreds of image files with a pattern and convert them at once

Cameras and phones name files IMG_4821.HEIC and DSC_0093.JPG. Marketplace bulk uploads, Shopify CSV imports and your own catalogue want product-001.jpg, blue-mug-front.jpg or SKU-based names that match a spreadsheet. Bulk Rename + Convert applies a naming pattern to a whole batch, shows the new names before you commit, converts the format if you ask it to, and packages the result as a ZIP.

How it works

  1. Upload the images in the order you want them numbered; reorder them if needed.
  2. Type a pattern using tokens. Set the start number if the sequence should begin at something other than 1.
  3. Optionally choose an output format (JPG, PNG or WebP) and quality to convert while renaming.
  4. Check the live preview list of old name to new name, then download the ZIP.
TokenMeaningExample output
{n}Sequence numberproduct-1.jpg
{n:3}Zero-padded to 3 digitsproduct-001.jpg

{width}Pixel width of the imagebanner-1920.jpg
{height}Pixel height of the imagebanner-1920x1080.jpg

Tokens can be combined freely: mug-{n:2}-{width}x{height} produces mug-01-2000x2000.jpg. The extension is always taken from the chosen format, or from the original when you are not converting.

Why file names matter to sellers

  • Sorting. Zero-padded numbers keep files in order everywhere: product-001, product-002 and product-010 sort correctly, while product-1, product-2 and product-10 do not.
  • Bulk listing files. Amazon flat files, Shopify CSV imports and Daraz batch templates reference images by URL or name. Predictable names such as SKU123-1.jpg through SKU123-7.jpg make those spreadsheets fillable with a formula instead of by hand.
  • SEO on your own store. Shopify and WordPress use the file name in the image URL and often as default alt text. A descriptive, hyphenated name like ceramic-mug-blue-front.jpg gives search engines context that IMG_4821.jpg never will.
  • Team hand-offs. Designers, virtual assistants and print shops all know what banner-1200x300.jpg is for without opening it.

Tips

  • Sort visually first with the Image Sorter & Organiser so the sequence matches how the listing should read: main, angle, detail, lifestyle.
  • Use lowercase letters, digits and hyphens only. Spaces and special characters get URL-encoded on the web and break some flat-file validators.
  • Combine renaming with conversion when a batch is HEIC or WebP; the Image Format Converter is the same engine without the naming step.
  • Add {width}x{height} when you keep several sizes of the same image so the 2000 px master and the 800 px thumbnail never get mixed up.
  • Rename after you resize. If the Bulk Image Resizer produces the final files, run them through here last so the numbers and dimensions are correct.
  • The EXIF Metadata Remover is worth a pass before publishing photos taken on a phone; renaming does not strip GPS data.

Privacy

Renaming and conversion happen in your browser. Your images never leave your browser: the new file names, the format conversion and the ZIP are all generated locally, and nothing is uploaded or recorded. It is a batch rename photos tool you can use offline once the page has loaded.

Frequently asked questions

How do I get file names like product-001, product-002?

Type product-{n:3} as the pattern. The 3 after the colon pads the number to three digits, so the first file becomes product-001.jpg. Use {n:2} for two digits or {n:4} for four. Set the start number if the sequence should begin at, say, 101.

What order are the numbers assigned in?

In the order the files appear in the upload list, which is the order you dropped them in. Reorder them before downloading if the sequence matters, or sort them first with the Image Sorter & Organiser and then upload the sorted set.

Can I rename files without changing the format?

Yes. Leave the format option on "Keep original" and only the names change; the image data is copied as-is, so there is no quality loss. Choose JPG, PNG or WebP only when you also need a conversion.

What does {date} insert?

Today's date in YYYY-MM-DD form, taken from the clock of your computer at the time of processing. It is handy for dated catalogue exports such as catalogue-{date}-{n:3}. It is not the capture date of the photo; that lives in the EXIF data.

Are duplicate names possible?

Not with {n} in the pattern, since every file gets a unique number. If you use only {original} or {date} and two inputs share a name, the ZIP builder appends a counter to the later one so the archive never contains two files with the same path.
