Resize several photos without stretching them

Set dimensions

1. Add JPG or PNG files, then enter maximum width and height in pixels.
2. Read the new dimensions shown for each image. Leave enlargement off to avoid increasing small photos.
3. Choose output format and JPG quality, then resize and download individual files or the ZIP.

Example: a 1,200-pixel bounding box

Maximum: 1,200 × 1,200 px
Landscape 4,000 × 2,000 → 1,200 × 600 px
Portrait 2,000 × 4,000 → 600 × 1,200 px
Small photo 300 × 150 → unchanged without enlargement

Dimensions and file size differ

A square bounding box does not crop photos square: each keeps its aspect ratio. To cut a border or choose an exact crop, use Crop and resize a photo.

Pixel width does not guarantee a file size in KB. Check the download; reduce dimensions or JPG quality further if a recipient imposes a size limit. Enlargement adds pixels without recreating details.

Formats and limits

PNG keeps transparency; JPG replaces transparent areas with white. Original metadata is not copied into generated files.
