About Image File Renamer
The Image File Renamer is a free online tool for renaming multiple image files at once. Whether you need to standardize filenames for a website, organize a photo archive, or prepare images for batch processing, this tool handles it all in your browser without any server upload.
Apply powerful batch rename rules — convert to uppercase or lowercase, replace spaces with underscores or hyphens, add a common prefix or suffix, and use find-and-replace for precise edits. You can also click any individual filename to edit it directly.
