Rename a whole batch of images from a pattern — a counter, the date, the dimensions — and see every new name before anything is downloaded. Your file never leaves this page. Everything happens in your browser, and there is no upload endpoint to send it to — that is checked by a build gate that fails if any network code reaches a tool’s bundle.
How to do it
- Drop your images onto the box.
- Build a pattern from the pieces offered.
- Check the new names, then download the batch as a zip.
Questions
Will the files sort correctly afterwards?
Yes. The counter is padded to fit the batch, so twelve files are numbered 01 to 12 and a hundred and twenty are numbered 001 to 120. Without the padding your computer sorts them 1, 10, 11, 2 — which defeats the point of renaming them.
What if two files end up with the same name?
You are told which ones, before you download anything. Two files with the same name overwrite each other when the zip is extracted, and it is silent — so the plan is checked and refused rather than carried out.
Why did it refuse a name?
Some names cannot be written. Windows refuses several punctuation characters and reserves a handful of old device names — a file called con.jpg cannot exist there at all. The page says which row and why.
What does “safe for the web” do?
Spaces become hyphens and accents are simplified, so Café becomes Cafe rather than Caf. The letter is kept; only the accent goes.
