Frequently Asked Questions
Will every image in the batch end up exactly the same size?
Yes — every image is resized to fit the same width/height you set, which is ideal for a uniform product gallery or batch of thumbnails.
Will my images get stretched to fill the exact dimensions?
No — like the single-image resizer, this preserves each image’s aspect ratio by default rather than forcing an exact stretch.
Can I upload images with different original sizes in the same batch?
Yes — each image is resized independently to fit your target dimensions, regardless of its original size.
How do I download all the resized images?
They’re packaged together into one ZIP file once the batch finishes processing.
Is there a limit on how many images I can resize together?
No fixed count limit, though larger batches take proportionally longer to process and download.
