How In-Browser Image Resizing & Scaling Works
Client-Side Image Resizer & Scaler runs entirely in your browser with JavaScript. There is no sign-up, and whatever you type or open here is processed on your device instead of being sent to a server.
Resize Photos and Graphics Locally in Your Browser
Scale image dimensions by exact pixel measurements (width and height) or percentage increments directly in browser memory using HTML5 Canvas. Because photos never leave your device, private family pictures, ID photos and confidential design assets are never uploaded or stored on a server.
Lock Aspect Ratio and High-Quality Smoothing
Lock aspect ratios with a single click to prevent image stretching or distortion when altering dimensions. The browser's high-quality smoothing keeps smaller copies sharp; enlarging cannot add detail, so enlarged images look softer.
Instant Dimension Preview and Download
A preview of the resized image updates as you type, and the downloaded file name includes the new size, for example photo_800x600.jpg.
Why processing in your browser matters
Many online tools upload your files or text to a server to process them. This one does the work on your computer or phone, so your data is not sent to us or stored anywhere else. That lowers the risk when you work with confidential material, although you should still follow your organisation's own rules. Read how this works in our Privacy Policy.
- No uploads: files are opened and saved on your device, so there is no upload or download wait.
- No account: nothing to sign up for or install.
- Free to use: no subscriptions or paywalls.
