Private browser tool
Resize an image without uploading it
Free, private, in-browser image resizing — nothing leaves your device. Apply one maximum width to a single image or a batch, with multiple results bundled into a ZIP.
How resizing works here
Enter a new width and height — or a percentage — and your browser redraws the image at that size, then gives you the result to download. It all runs locally, so nothing is uploaded. Lock the aspect ratio to keep proportions correct, or set exact dimensions when a form or platform demands a specific pixel size.
When to resize an image
- Exact dimensions: hit the pixel sizes required for avatars, banners, or ID-photo uploads.
- Smaller files: scale a large photo down before emailing it or posting it to the web.
- Thumbnails: create small preview versions of larger images.
- Fit a layout: size an image to match a slide, document, or print dimension.
Keeping images sharp when you resize
Scaling an image down almost always looks clean. Scaling up can't invent detail that isn't there, so enlarging a small image will look soft. Keep the aspect ratio locked to avoid stretching, and if you need the smallest possible file, resize first and then run it through the compressor.
Frequently asked questions
Are my images uploaded to a server?
No. Resizing happens entirely in your browser, so your images never leave your device.
Will resizing distort my image?
Not if you keep the aspect ratio locked. Unlocking it lets you set width and height independently, which can stretch the picture.
Can I make an image larger?
Yes, but upscaling can't add real detail, so enlarged images tend to look softer than the original.
Can I resize a batch at once?
Yes. Add multiple images and download the resized set together as a ZIP.
Is there a size limit?
No fixed cap — very large images just use more of your device's memory.
