What is Image Resizer?
An Image Resizer is a tool used to change the dimensions (width and height) of a digital image. Whether you need to shrink a high-resolution photo for a website, adjust an image for social media, or reduce dimensions for email attachments, this tool makes it easy. It allows you to specify exact pixel dimensions or resize by a percentage (e.g., 50% smaller). The tool includes an 'Aspect Ratio' lock to prevent distortion, ensuring your images don't look stretched or squashed. All resizing happens locally in your browser, guaranteeing privacy.

Frequently Asked Questions
Does resizing reduce quality?
Making an image smaller usually looks great. Making it bigger can make it look blurry or pixelated.
Can I resize multiple images?
I focus on one image at a time to give you precise control over the dimensions.
What formats are supported?
I work with all the popular ones: JPG, PNG, and WebP.
Is my image uploaded?
No. I resize everything right here in your browser using your computer's power.
How do I keep the shape correct?
Keep 'Lock Aspect Ratio' checked. If you change the width, I'll automatically fix the height so it doesn't look squashed.
Can I resize by file size (KB)?
I resize by pixels. If you want to make the file size smaller (KB) without changing the dimensions, use my Image Compressor tool.
Does it remove EXIF data?
Yes, creating a new resized image usually strips out the old metadata.
