Frequently Asked Questions
How do I resize an image?
Upload your image, enter your desired width or height, and click 'Resize Image'. You can choose to lock the aspect ratio to prevent distortion.
Does reducing image size affect quality?
Reducing dimensions usually maintains visible quality. However, if you enlarge an image significantly, it may appear pixelated. Our tool uses high-quality resampling to minimize quality loss.
Can I convert images to other formats?
Yes. You can upload a PNG or WebP image and choose to save the resized version as a JPEG, or vice versa.
Is it safe to use?
Yes. All image processing happens locally in your browser using the Canvas API. Your photos are never uploaded to any server.
What is aspect ratio?
Aspect ratio is the proportional relationship between the width and height of an image. Locking it ensures your image doesn't look stretched or squashed when resizing.
What image formats are supported?
The tool supports JPEG, PNG, and WebP uploads. You can also convert between these formats while resizing — for example, upload a PNG and download as WebP for smaller file sizes.
Can I resize images for social media?
Yes. Common sizes include 1080×1080 px for Instagram posts, 1200×630 px for Facebook/Twitter link previews, and 1280×720 px for YouTube thumbnails. Enter the exact dimensions you need.
