Resize images to exact dimensions
Set a width and height in pixels, scale by a percentage, or pick a preset like 1080×1080 — and apply it to one image or a whole batch at once. The aspect ratio stays locked unless you unlock it, so nothing comes out stretched. Resizing happens in your browser using the same scaler your browser uses to draw images, with no upload and no queue.
How to resize an image
Add your images
Drop in one file or many. Each one's current dimensions are listed.
Choose the new size
Type exact pixels, set a percentage, or pick a preset. With the ratio locked, the other dimension follows automatically.
Resize and download
Press Resize. A single image downloads directly; a batch comes back as a ZIP.
What Resize Image can do
Batch resizing
Apply one size to a whole folder of images in a single pass.
Pixels, percent or preset
Three ways to say the same thing, depending on what you're given.
Aspect ratio locked
Nothing comes out squashed unless you deliberately unlock it.
No upload
Images are scaled in the tab — no waiting on a server round trip.
Resize Image — frequently asked questions
How do I resize an image to an exact pixel size?
Switch to pixel mode and type the width and height. If you need both numbers to be exact regardless of shape, unlock the aspect ratio first — otherwise the height follows the width.
Can I resize several images to the same size at once?
Yes. Drop them all in, set the size once, and download the batch as a ZIP.
Does resizing reduce the file size too?
Usually, since there are fewer pixels to store. If you need to hit a specific file size in KB, use Compress Image, which targets file size directly.
Will enlarging a small image make it sharper?
No. Scaling up invents pixels rather than recovering detail — the result will look soft. Always start from the largest original you have.
Do my images get uploaded to a server?
No. Every tool on Notoo Tools runs as JavaScript and WebAssembly inside your browser tab. There is no server that receives your files — you can disconnect from the network after the page loads and the tool keeps working.
Do I need an account or a subscription?
Neither. There's no sign-up, no email, no free-tier limit and no watermark. Bookmark the tool and it opens straight into the work.
