ResizeFox

MULTIPLE IMAGE RESIZER

Resize Images in Bulk

Give several JPG, PNG or WebP files the same output width in one operation. Each image keeps its own proportions and can be downloaded separately.

Photo dimensions & file-size quick reference

Dimensions are width × height in pixels. Suggested file sizes are compression targets, not platform limits.

Need another shape? Crop first, then resize and compress. Keep your original; do not sacrifice detail just to reach a suggested target. JPG is usually suitable for photos. Etsy does not preserve PNG transparency.

Etsy and Pinterest guidance was checked on this date. Instagram, Facebook and vertical-canvas entries are practical ResizeFox suggestions, not a complete list of accepted dimensions or verified maximum file sizes. Check the destination’s uploader for its current limit: posting apps, advertising tools and APIs may have different requirements.

How to use this tool

1

Select several files

Choose a group of supported images from the same folder.

2

Enter one width

The height of each image is calculated from its original aspect ratio.

3

Resize the batch

Process the group and download each finished JPG from the results list.

How batch resizing handles different shapes

Every image receives the chosen width, while its height is calculated independently. A square, portrait and landscape file will therefore keep different heights without becoming distorted.

Batch output uses JPG for broad compatibility. Transparent PNG areas receive the browser canvas default background, so use the single-image PNG resizer when transparency must be preserved.

Common uses

Prepare a consistent maximum width for article and gallery images.

Marketplace photos

Resize a product set while keeping portrait and landscape proportions.

Are images uploaded to a server?

Will the original file be changed?

No. The downloaded result is a new file; your original remains untouched.

Which formats can I use?

The tool accepts JPG, PNG and WebP. Some operations export JPG or PNG depending on the selected page.
