Frequently Asked Questions
How do I resize multiple images at once?
Select all your images in the upload box, enter the target width and optional height, then click Resize. Everything comes back in one ZIP file.
Will all images keep their proportions?
Yes. Each image is scaled to fit inside the size you set without stretching, so portrait and landscape photos are both handled correctly.
How do I make all my images the same width?
Enter only the width (for example 1200) and leave the height empty. Every image becomes 1200 px wide with its height adjusted automatically.
How many images can I resize in one batch?
There is no fixed cap — you can upload as many as you need. Very large batches just take longer.
Can I batch resize photos for Shopify, Amazon or eBay?
Yes. Enter the marketplace’s recommended size, such as 2048×2048 for Shopify or 1600 px for Amazon zoom, and resize the whole catalogue at once.
Do the file formats change?
No. Each image keeps its own format; a mix of JPG and PNG comes back as the same mix.
Can I bulk resize and compress at the same time?
Resize here first, then run the ZIP’s images through the Bulk Image Compressor for the smallest files.
How do I extract the ZIP?
Double-click it on a computer, or open it in the Files app on your phone, to get the resized images.
Does it work on Mac, Windows and mobile?
Yes, it runs in any modern browser with nothing to install.
Does the Bulk Image Resizer store my images?
No. The batch is processed in memory and deleted as soon as the ZIP is created.
