Image Resizer
Resize photos to exact pixel dimensions or a percentage — processed locally, never uploaded.
Set an exact width and height in pixels, or scale everything by a percentage — then drop in one image or thirty. Resizing runs on the Canvas API inside your browser, so photos never touch a server: ID photos, marketplace listings, and client work all stay on your device.
The aspect-ratio lock keeps proportions true so nothing comes out stretched, and every image shows its new dimensions and file size before you download. JPG and WebP output includes a quality slider, because resizing is also the perfect moment to shed file weight.

Drop one or more images onto the tool, or click to browse.

Why use Nofolo’s image resizer?

A quality slider for JPG and WebP output sheds extra file weight while you resize.
Frequently asked questions
Are my images uploaded when I resize them?
No. Resizing happens in your browser with the Canvas API — files never leave your device, and the tool keeps working even if you go offline after the page loads.
How do I resize an image without stretching it?
Keep the aspect-ratio lock on. Set the width (or height) you need and every image scales proportionally from its own dimensions, so nothing looks squashed.
Can I resize multiple images at once?
Yes — drop as many as you like. In pixel mode with the lock on, each image is scaled to your target from its own aspect ratio; in percentage mode every image is scaled relative to itself.
Does resizing make images blurry?
Downscaling stays sharp — browsers use high-quality resampling. Enlarging beyond the original size cannot invent detail, so expect some softness above 100%.
What is the difference between resizing and compressing?
Resizing changes pixel dimensions; compressing re-encodes the same dimensions into a smaller file. Resizing usually saves far more space — a 4000px photo scaled to 1600px drops most of its weight before compression even starts.
