What is an Online Image Resizer?
An online image resizer changes the pixel dimensions of a photo so it fits websites, forms, social platforms, or storage limits while keeping the image usable.
Benefits
• Resize to exact width and height
• Lock aspect ratio to avoid distortion
• Export as PNG, JPEG, or WebP
• Preview resized output before download
• Private browser-based processing
Use this image resizer when you need smaller file sizes, platform-specific dimensions, or consistent image sizes across a project.
When to use Online Image Resizer?
Use an online image resizer when the pixel dimensions of a photo matter more than reframing it. Resizing helps images fit upload limits, layout requirements, and performance goals.
Common use cases
• Reducing image file size for faster website loading and email attachments
• Matching platform requirements for blogs, forms, and application uploads
• Creating consistent image dimensions across a product catalog or gallery
• Preparing images for presentations, documents, and slide decks
• Generating smaller preview versions while keeping the original aspect ratio
When you only need to change dimensions and not the visible frame, resizing is quicker than cropping and works well alongside other image tools.

Frequently Asked Questions - FAQs
Will resizing reduce image quality?
Making an image smaller usually keeps good visual quality. Enlarging images may look softer because new pixels are interpolated.
Can I keep the original aspect ratio?
Yes. Turn on lock aspect ratio and changing width or height will update the other dimension automatically.
Is my image stored anywhere?
No. Resizing happens entirely in your browser.
Is this online image resizer safe to use?
Yes. Your images are processed entirely in your browser and are not uploaded to our servers, stored, or shared. This keeps your files private on your device.
