How does the image resizer work?
This tool uses your browser's built-in Canvas API to redraw your image at the new dimensions you specify. The entire process runs locally on your device — your images are never sent to any server.
Frequently Asked Questions
Does resizing reduce image quality?
Enlarging an image beyond its original size may cause some blurriness, since the browser must interpolate new pixels. Reducing dimensions preserves quality well. For best results, only downscale or keep close to the original size.
What is aspect ratio lock?
When the aspect ratio is locked (the default), changing the width automatically adjusts the height to keep the same proportions — and vice versa. This prevents your image from looking stretched or squished. You can unlock it if you need custom proportions.
What are the quick presets?
Presets let you quickly resize to common dimensions. Percentage presets (25%, 50%, 75%) scale relative to the original size. Dimension presets (1920×1080, 1280×720, etc.) set exact pixel values — useful for social media, thumbnails, or web publishing.
