About Resize Image
Resize JPEG, PNG, and WebP images to exact dimensions, a percentage of the original, or by constraining the longest side. Maintains aspect ratio by default. All processing happens locally in your browser.
How It Works
Your image is decoded into an ImageBitmap, then drawn onto a Canvas element at the target dimensions. The browser's built-in resampling algorithm (typically bicubic) handles the scaling for smooth results.
Step by Step
- 1 Upload one or more images (JPEG, PNG, or WebP)
- 2 Choose a resize mode: exact dimensions, percentage, or longest side
- 3 Enter your target values (e.g. 800×600, 50%, or 1200px longest side)
- 4 Click Resize to process your images
- 5 Download the resized results
Tips
- Use 'Maintain aspect ratio' to avoid stretching or squashing images.
- For social media, common sizes are 1200×630 (OG), 1080×1080 (Instagram square).
- Reducing image dimensions also reduces file size significantly.
- The longest-side mode is useful for constraining images to a maximum dimension.
Frequently Asked Questions
Will resizing reduce file size?
Yes — smaller dimensions mean fewer pixels, which reduces file size. A 4000×3000 photo resized to 800×600 can be 10-20x smaller.
What happens if I don't maintain aspect ratio?
The image will be stretched to fit the exact dimensions you specify, which can distort the image.
Is my image uploaded to a server?
No. All resizing happens in your browser. Your images never leave your device.
