How to Use Image Resizer
To resize an image, upload it by clicking the upload area or dragging it onto the page. Enter your desired width and height in pixels. The lock aspect ratio option maintains the original proportions automatically — enter either width or height and the other value updates to match.
After setting your dimensions, click Resize to generate the resized image. A preview is shown and you can download the result. This tool is useful for preparing images for social media uploads, email attachments, website thumbnails, or any context requiring a specific image size.
Frequently Asked Questions
Can I resize an image without losing quality? expand_more
Enlarging an image beyond its original dimensions will reduce sharpness since there is no new pixel data to add. Reducing image size (downscaling) can be done with minimal quality loss.
What does 'lock aspect ratio' do? expand_more
Locking the aspect ratio maintains the original width-to-height proportions. When you change one dimension, the other is automatically calculated to prevent the image from appearing stretched or squished.
What image formats does the resizer support? expand_more
The tool supports JPG, PNG, and WebP images as input. Output is typically downloaded as a PNG or JPG file.
Are my images sent to a server when resizing? expand_more
No. All resizing is done locally in your browser using the HTML5 Canvas API. Your image file never leaves your device.
What is the maximum image size I can resize? expand_more
There is no enforced limit, but very large images (over 20 megapixels) may be slow to process or may run into browser memory limits on lower-end devices.
