How to Enlarge Images Online
SmarterSources' image enlarger lets you increase the dimensions of any image directly in your browser. Whether you need to upscale a thumbnail for printing, enlarge a photo for a presentation, or make an image bigger for social media, this tool handles it instantly with high-quality interpolation.
Quick Scale Presets
Use the 1.5x, 2x, 3x, or 4x buttons for common enlargement factors. A 2x scale doubles both the width and height of your image, resulting in 4x the total pixels.
Custom Scale
Use the slider for precise control from 100% to 800%. You can also enter exact pixel dimensions — the aspect ratio stays locked by default to prevent distortion.
High-Quality Interpolation
The tool uses the browser's highest-quality bicubic interpolation algorithm to fill in new pixels smoothly, producing the best possible result for browser-based upscaling.
Frequently Asked Questions
Will enlarging reduce image quality?
Enlarging always involves creating new pixels that weren't in the original. The browser uses high-quality interpolation to make this as smooth as possible, but some softness is inevitable. For best results, keep enlargement under 4x.
What's the maximum enlargement?
You can enlarge up to 8x (800%). Very large enlargements on high-resolution images may be limited by your device's available memory.
How is this different from the Image Resizer?
The Image Enlarger is focused specifically on making images bigger with presets optimized for upscaling. The Image Resizer handles both enlarging and shrinking, plus includes social media dimension presets.
