Batch image renamer
Prepare product photos, scanned pages or event pictures with consistent filenames before uploading them elsewhere. Enter a pattern such as product-{n} or {name}-{n}; the preview shows the exact result for the first 20 images. The ZIP contains the original image bytes under the new names, plus a CSV map you can check or keep for records.
How to use this tool
- Upload JPG, PNG, WebP or GIF images, drag them into the dropzone, or import a direct public image URL. Try the example image.
- Enter a pattern with {n} for numbering and optional {name} for the cleaned original name. Choose the first number, digit count and order.
- Create the ZIP, review the preview and rename map, then extract the ZIP to use the new filenames. The original files stay unchanged.

Output and limitations
Rename JPG, PNG, WebP and GIF images in a batch with a numbered filename pattern. Preview old and new names, then download a ZIP and CSV rename map.
Choose 1 to 100 images, no larger than 20 MB each or 50 MB in total. The pattern uses {n} for a padded sequence and {name} for each cleaned original name; the extension stays unchanged. Numbers follow upload order or filename order. Duplicate or unsafe output names stop the batch. Image bytes are copied without resizing, recompression or metadata changes. GIF animation is preserved. A ZIP download does not rename files already on your device.
Will this change image quality or the files on my computer?
No. The ZIP copies each supported image byte for byte under a new filename. It keeps image dimensions, EXIF, transparency and GIF frames as they were. Your uploaded originals remain unchanged; extract the ZIP to use the renamed copies.
What if the pattern creates the same filename twice?
The tool stops before exporting a ZIP when names collide, including names that differ only by letter case. Add {n} to the pattern or choose a different order. Unsupported image data is rejected rather than renamed as an image.
What if processing fails?
Check the supported formats and file limits, then try a smaller file. Keep an original copy. A clear error message will explain an unsupported input or an unavailable processing service.
