Free Local Image Resizer
Resize one or many images at once, entirely in your browser — nothing is uploaded to a server. Enter the target width in pixels and the height scales proportionally to preserve the image's aspect ratio.
For scanned documents, the optional Document Enhancement panel lets you adjust brightness and contrast, apply a black-and-white "scan mode," and enable a light sharpening pass, so a resized photo of a page reads more clearly. Upload more than one image and AiFileStudio will batch-process them and hand you back a single ZIP file.
Frequently Asked Questions
Does resizing upload my images anywhere?
No. Resizing happens entirely on your device using the HTML5 canvas API — your images never leave your browser.
What's the maximum number of images I can resize at once?
There's no hard-coded limit; it depends on your device's memory. A handful to a few dozen images at a time works comfortably on most modern browsers.
What does 'B&W Mode (Scan)' do?
It converts each pixel to pure black or white based on brightness, which can make scanned text documents look cleaner and more print-like.
