Batch image resize & rename
Resize and consistently rename many images in one private browser workflow.
A practical guide to Batch image resize & rename
Batch Image Resizer and Renamer processes several images in picker order, fits each within maximum width and height limits, applies a filename pattern, and packages the results into one ZIP. Source files are decoded and exported locally in the browser.
Example: prepare a folder for a web gallery
Select the photos, set a 1600-pixel maximum, choose JPEG for delivery, use a pattern such as gallery-name, and inspect the ZIP names before uploading the collection.
Task-specific steps
- 1
Choose the complete set of images and confirm the thumbnail list preserves the order that should become the numbered output sequence.
- 2
Set the maximum dimensions, select PNG, JPEG, or WebP, and enter a pattern using the original name and padded number tokens.
- 3
Create the ZIP, open several outputs at full size, and verify the names before replacing any source folder.
Options that affect the result
- Maximum width and height limit the result while preserving each source aspect ratio without enlarging smaller images.
- The rename pattern supports the original stem and an ordered number, while duplicate requested names receive a safe suffix.
Limitations to know first
- Resizing reduces pixel dimensions but cannot restore detail lost in a small or heavily compressed source.
- A ZIP download is a container rather than a single previewable image, so its contents must be opened or extracted before review.
Questions specific to this task
Will a small image be enlarged to the maximum size?
No. The batch fit keeps smaller images at their source dimensions and only scales down images that exceed either maximum.
What happens when two files produce the same name?
The export keeps both files by adding a numeric suffix to the later duplicate instead of overwriting the first ZIP entry.
