Resize Multiple Images
Select your images, pick a size, and resize them all at once. Proportional scaling, no cropping, instant ZIP download.
Resize Images for Web, Email, and Social Media
Uploading full-resolution photos to a website or sending them by email is often impractical. A single photo from a modern camera can weigh 15 to 30MB, and a batch of 50 images can easily exceed 1GB. Most websites, email clients, and social platforms do not need that resolution.
This tool lets you resize multiple images at once to a practical size. You pick the longest side (for example, 1600px for web or 1200px for email), and the tool scales every image proportionally. No cropping, no stretching, no quality loss beyond the natural downscale.
The entire process happens in your browser. Your images are never uploaded to any server. When processing is done, you download a single ZIP file with all resized images, ready to use.
Why Resize Images Before Sharing?
Smaller images load faster on websites and social media feeds. A photo resized to 1600px on the longest side is sharp enough for any screen, including Retina displays, while being a fraction of the original file size.
Email attachments have size limits. Most email providers cap attachments at 25MB. By resizing your photos to 1200px, you can typically fit 20 to 30 images in a single email instead of just 2 or 3.
Social media platforms (Instagram, Facebook, LinkedIn) compress uploaded images anyway. By resizing to their recommended dimensions before uploading, you control the quality instead of letting the platform's algorithm decide.

Frequently Asked Questions
Will resizing reduce the quality of my photos?
Downscaling naturally reduces the pixel count, but the visual quality remains excellent. For web and social media, a 1600px image is indistinguishable from a 6000px original on any screen.
Can I resize PNG images with transparency?
Yes. PNG files are resized as PNGs, preserving transparency. JPG and WebP files keep their respective formats as well.
What happens to EXIF data?
The browser canvas API used for resizing strips EXIF data. If you need to preserve metadata, consider resizing in Lightroom or a similar tool.
Is there a cost or signup required?
No. The tool is completely free, requires no account, and adds no watermark. You can use it as many times as you want.
Can I resize images to exact pixel dimensions (width x height)?
This tool resizes by longest side to maintain proportions. For exact width x height dimensions, use our single Image Resizer tool which supports custom dimensions and Instagram presets.
How long does it take to resize 100 images?
On a modern computer, resizing 100 images typically takes 15 to 30 seconds. Mobile devices may take slightly longer depending on the file sizes.
