What Is Bulk Image Resizing?

Bulk image resizing lets you scale dozens or hundreds of photos simultaneously instead of manually opening and resizing each picture one by one.

By applying a standardized width, height, or uniform percentage reduction across an entire folder of photos, you save hours of repetitive work while keeping your visual assets consistent across your storefront or blog.

How to Batch Resize Photos (Step-by-Step)

Batch resizing multiple photos takes only a few seconds from your browser:

1

Select or Drop Multiple Images

Drag and drop a batch of JPG, PNG, or WebP photos into the upload area above.

2

Configure Target Size

Enter target dimensions (such as max width 1200px) or choose percentage scaling (e.g. 50%). Proportions are maintained automatically.

3

Process and Download ZIP

Click Process All to resize every image simultaneously, then download the entire batch as a single ZIP file.

Set Uniform Dimensions or Percentage Scaling

With the bulk resizer, you can select whether to resize by fixed pixel dimensions or by a uniform percentage.

For e-commerce catalogs where every product image needs to fit an 800x800 or 1200x1200 thumbnail grid, fixed dimensions with aspect fitting ensure clean consistency. For camera rolls or vacation photos where original resolutions vary, percentage scaling reduces file weights proportionally across all files.

Download All Resized Images as a ZIP

Instead of clicking 'Save' dozens of times, TinyImageResizer packages your completed batch into a clean, organized ZIP archive.

Your original file naming conventions are preserved so you can quickly unpack the resized photos right back into your project folders.
