Rename a whole set of images to a clean, sequential naming scheme in one pass — app_01, app_02, app_03 — instead of clicking through them one at a time. Useful for product photos, portfolio exports, catalog uploads, and any workflow where a downstream system expects predictable filenames. It all runs in your browser, so nothing is uploaded.
Three steps: drop in your images, set the prefix, separator, starting number, and zero padding, then process and download a zip. Files are sorted naturally before numbering, so img2 comes before img10 the way you'd expect rather than the 1, 10, 2 ordering that plain alphabetical sorting produces. Nothing is re-encoded — only the filename changes, so the image data is bit-for-bit identical to your originals.
Frequently asked questions
- How is the numbering order decided?
- By natural sort on the original filenames, so img2 lands before img10 — the same ordering your file manager uses. You won't get the 1, 10, 2, 20, 3 mess that raw alphabetical sorting causes.
- Does renaming affect image quality?
- Not at all. Only the filename changes. The image data isn't re-encoded, so every output file is byte-identical to its original.
- Do my files get uploaded?
- No. Renaming and zipping both happen locally in your browser and your images never leave your device.
- Are there usage or file-size limits?
- Runs are unlimited. Files can be up to 50 MB, and batch tools accept up to 50 files at once.
