About this tool

The aspect ratio is always kept, whichever of width, height, or percentage you use. Resizing more than one image saves them together as a ZIP file.

Supports JPG, PNG, and WebP.

This tool runs entirely in your browser. Your files are never uploaded to our server.

When to use it

Useful when you want to match the width of photos for a blog post or social media post — set one width and every photo is resized to it.

Also useful for shrinking a whole folder of images by the same percentage at once, since each image keeps its own aspect ratio even when the originals are different sizes.

FAQ

Can I enlarge an image beyond its original size?
Yes. Entering a width, height, or percentage larger than the original enlarges it — the more you enlarge it, the softer the image quality gets.
What happens if one of my images cannot be loaded?
A corrupted file or an unsupported format is skipped, and the rest of your images are still resized.
Will a photo taken in portrait mode on my phone come out sideways?
No. Each image is automatically rotated to match its embedded orientation (EXIF) before resizing, so it keeps the orientation you saw when you took it.
