Image Resizer
Resize any image to exact pixel dimensions in seconds — free, no signup, and your photos never leave your browser.
Need to resize an image online? Our free image resizer lets you change the width and height of any photo or graphic to the exact pixel size you need. Whether you are preparing a profile picture, shrinking a photo so it fits an email attachment limit, or creating web-ready images at 1920, 1280, or 800 pixels wide, you can get it done in a few clicks with no software to install.
The aspect ratio lock is on by default, so changing the width automatically adjusts the height — your image keeps its natural proportions and never comes out stretched or squashed. Prefer speed? Use the one-click presets for 25%, 50%, or 75% scaling, or jump straight to common web widths. You can also pick your output format: JPEG for photos, PNG when you need transparency or crisp graphics, or WebP for the smallest file sizes on modern browsers.
Everything happens locally on your device. Your original image is never uploaded to a server, never stored, and never analyzed — resizing is done entirely in your browser, and the resized file downloads straight to your computer. No accounts, no watermarks, no limits on how many images you can resize.

Frequently asked questions
Will resizing stretch my image?
Not with the aspect ratio lock enabled (it is on by default). The lock keeps your image's original proportions, so it shrinks or grows evenly without distortion. Turn the lock off only if you deliberately want to stretch or crop to different proportions.
Which output format should I choose?
JPEG is best for photos and gives the smallest files. PNG keeps transparency and is ideal for logos and graphics with sharp edges, but produces larger files. WebP offers the best size-to-quality ratio and works in all modern browsers.
Is there a maximum image size?
There is no hard limit — you can resize images to any dimensions your device's memory can handle. Extremely large photos (tens of megapixels) may take a few extra seconds on older devices.
Are my images private?
Yes. Resizing happens entirely in your browser; your images are never uploaded, stored, or seen by anyone else.
