Tips for batch resizing product photos
Keep every image the same square size for a tidy, professional-looking grid. Pad to a white square for marketplaces that expect a clean, uniform background. Always resize down from high-resolution originals, never up — scaling up cannot add detail that was never captured. To shrink file sizes too, use the image compressor; for a single image, use the image resizer.
Frequently asked questions
How many images can I resize at once?
As many as your browser can hold in memory; they are processed one after another and listed for download. Very large batches (hundreds) may be slow because everything runs locally.
Does bulk resizing upload my images?
No; every image is resized in your browser via the HTML canvas and never sent to a server.
Can I download all resized images at once?
Each result has its own Download button; click through the list. (Browsers block automatic multi-file downloads for security.)
Will resizing reduce quality?
Scaling down stays sharp; scaling a small image up cannot add detail, so start from the largest originals you have.
