How to use
Select up to 20 files. Each image is reduced to fit within the maximum width and height, then included in a ZIP.
Limits and behavior
Images are never enlarged. Browser canvas resampling is used. At most 80 MB input, 16 million decoded pixels and 64 MB output. Still PNG, JPEG and WebP only; 20 MB, 4 megapixels and 4,096 pixels per side. Processing stays on your device. Exports apply orientation and discard source metadata. PNG output preserves transparency unless the selected operation composites it.
Resize multiple images in one batch
Use this bulk image resizer to resize a set of photos proportionally to fit within chosen dimensions. It is useful for preparing a collection of images for a website, catalog or document.
Will batch resizing stretch my photographs?
The tool scales images proportionally within a bounding box. It is intended to preserve the aspect ratio rather than force every image into an exact distorted rectangle.
