Your images never leave your device
How to use Image Resizer
- Drop your images on the page or pick them from your device.
- Choose pixels or percent, then enter the new size. Keep the aspect lock on to avoid stretching.
- Wait while each image is resized on your device.
- Download the results one by one, or all together as a zip.
Frequently asked questions
Will resizing make my image blurry?
Making an image smaller does not make it look blurry; a good resampling method keeps it sharp at the new size. Blur comes from enlarging images, and this tool never enlarges them.
Can I make an image larger with this tool?
No. The resizer only reduces images. Enlarging cannot create real detail, so the result would just be a bigger, softer picture. Use the original, higher-resolution file instead.
Does resizing reduce the file size?
Yes, usually a lot, because the image has fewer pixels to store. Halving both width and height cuts the pixel count to a quarter. For further reduction, run the result through the image compressor.
Should I resize by pixels or by percent?
Use pixels when the destination states a size, such as a maximum width. Use percent to shrink a mixed batch of images by the same proportion.
Are my images uploaded?
No. Resizing happens in your browser with WebAssembly. Your images never leave your device, and there is no signup or watermark.
About Image Resizer
The resizer shrinks images to the dimensions you choose. Work in pixels when you need an exact limit, such as 1920 pixels wide for a website banner, or in percent when you want the same proportional reduction across a batch of photos with different shapes. With the aspect lock on, entering just a width or just a height is enough: the image is scaled to fit inside the box you describe and its proportions stay the same. Turn the lock off only when you really want to stretch the image to exact width and height.

The tool only makes images smaller. It never enlarges them, because upscaling cannot add detail that is not in the file, and it would only produce a bigger, blurrier image. Shrinking uses high-quality Lanczos resampling, which keeps edges crisp, so a reduced photo looks sharp at its new size. If you need a bigger picture, the honest answer is to go back to the original or a higher-resolution source.
Resizing is the most effective way to reduce a file's size. Reducing a 12-megapixel phone photo to around 2000 pixels on the long edge cuts the pixel count by roughly two thirds, and the file shrinks with it. That is plenty for a full-screen web image, an email or a document. Common targets are 1200 by 630 pixels for link previews, 1080 pixels wide for social posts and 800 to 1600 pixels wide for blog images.
Everything runs in your browser. Images up to 50 megapixels are accepted, several files are processed in parallel, and nothing is uploaded. The output keeps the original photo's orientation, and metadata such as GPS location is not carried into the resized file.
