Bulk Rename Images

No. Renaming changes the filename and ZIP packaging only. It does not resize, recompress, convert or edit the image pixels.

No. The original files on your device remain unchanged. The downloaded ZIP contains copies of the selected files using the generated filenames.

Yes. Keeping the original extension should be the default behavior. Extension normalization may change the letter case, but it should not convert the underlying image format.

Yes. You can choose a start number, number position and padding such as 1, 01, 001 or 0001 when those controls are available.

Padded values such as 001, 002 and 010 are more likely to remain in the expected order when files are sorted alphabetically by a file manager, CMS or server.

Yes. Use the option for editing existing names or include the original-name token in an advanced naming pattern when that feature is available.

Yes. A prefix is added before the main filename, while a suffix is added after the main name and before the file extension.

Yes, when Edit existing names is available. You can replace repeated words, spaces, separators or other matching text while keeping the rest of the filename.

The tool should show a duplicate warning and prevent ZIP creation until the conflict is resolved. It should not silently overwrite one file with another.

Yes. Reorder the file queue before creating the ZIP so sequence numbers follow the intended image order.

No. Renaming changes filenames only. Use a real image converter when you need to change PNG, JPG, WebP or another image format.

Yes, but separate batches may produce clearer and more consistent filename patterns when the files belong to different workflows.

No. Changing extension text alone does not convert the image data. A PNG renamed with a .jpg extension is still a PNG internally and may not open correctly.

Supported formats should match the file types accepted by the upload control. Check the current tool interface for the tested input formats instead of assuming every image format is accepted.

Browsers cannot normally rename source files directly on your device. A ZIP archive provides copies of the selected files with the generated filenames.

Yes. ZIP creation depends on the number and size of selected files and the available browser memory. Use smaller batches when the browser becomes slow or cannot complete the archive.
