Here’s how to get the most out of image resizer.
Our browser-based Image Resizer uses high-quality HTML5 Canvas interpolation to scale photos cleanly without uploading a single byte to any remote server. Whether you are preparing a 1200×630 Open Graph banner, a 1080×1080 Instagram post, or resizing product photography for an online store, all processing happens locally on your device.
A few things you might want to know before you start.
No. All image decoding, scaling, and encoding happen 100% inside your web browser. Your files never leave your computer or phone.
Keep the "Lock Aspect Ratio" toggle enabled. When you enter a new width, the height automatically adjusts proportionally.
Yes. Drop multiple images into the workspace, apply your dimension or percentage rule, and export each resized image.
Lowering pixel dimensions significantly reduces file size. For additional byte reduction without changing dimensions, use our Image Compressor next.
