Image Resizer
Resize one or many images to an exact pixel size, with the aspect ratio locked if you need it.
Runs entirely in your browser, nothing is uploadedDrop images here, or click to browse. JPG, PNG, and WebP supported.
Resize in three steps
- Drop in one image or several at once, any mix of JPG, PNG, or WebP.
- Set the target width and height, and keep the ratio locked to avoid stretching.
- Select resize, then download each image on its own or grab them all in one ZIP.

Everything worth knowing before you dive in.
How it helps
Resizing an image for a website, a form upload, or a print template usually means opening an editor just to change two numbers. This tool skips that step: pick a target width and height, and every image dropped in gets resized to match, right in the browser tab.
Built for real use
The aspect ratio lock recalculates the second dimension automatically as you type, so you never end up with a squashed photo. For a batch of product photos or a folder of screenshots, uploading several files at once and downloading a single ZIP saves a lot of repetitive clicking.
Private by default
Every resize happens on your own device using the canvas API, so large or sensitive images never touch a server. Quality is preserved as closely as the target size allows, whether you're resizing one file or fifty.
Pro tip
When resizing for the web, matching the exact display size in your layout, rather than uploading a much larger image and letting CSS scale it down, keeps page load noticeably faster.
Common questions
What image formats can I resize?
JPG, PNG, and WebP are all supported for both upload and download.
Will resizing distort my image?
Not if the ratio lock stays on. It recalculates the height whenever you change the width, so proportions stay correct.
Is there a limit on how many images I can resize at once?
No hard limit is enforced, though very large batches depend on your device's available memory.
