Rename 1,000 images at once — no re-encoding
Unlike tools that compress or resize during rename, this tool copies each file's binary data as-is and places it in the ZIP under the new name. Your pixel data is untouched. This makes it safe for professional workflows where quality matters.
FAQs
Does renaming re-encode the images?
No. Files are read as raw ArrayBuffers and added to the ZIP unchanged. Zero quality impact.
What patterns are supported?
Prefix + counter (product_001.jpg), find & replace (DSC → portrait), and today's date prefix (2024-09-20_filename.jpg).
Can I preview before downloading?
Yes — a live preview shows original → new name for every file as you type.
Are original file extensions preserved?
Yes. File extensions (.jpg, .png, etc.) are kept intact so your operating system recognizes the renamed files.
