What is resize image?

Resizing an image changes its pixel dimensions - making it smaller for web use, email attachments, or social media, or larger for print. PixlUtils resizes images entirely in your browser using the Canvas API. Lock the aspect ratio to preserve proportions, or enter custom width and height values freely. Supports pixel and percentage-based resizing with a quality slider for the output. No upload, no signup, free forever.

How it works

Three steps to resize your image to any dimension - no software needed.

1

Upload your image

Click the upload area or drag and drop a JPG, PNG, WebP, GIF, or BMP file. Files stay 100% on your device.

2

Set dimensions

Enter new width and/or height in pixels, or switch to percentage mode. Toggle the aspect ratio lock to keep proportions.

3

Download the resized image

Hit Resize and download instantly. Choose output format and quality before saving.

💡 Pro Tips

Always lock aspect ratio for photos

Entering only one dimension with the lock on prevents stretching - the tool calculates the other dimension automatically.

Resize before compressing to save more space

A photo displayed at 800px wide doesn't need to be stored at 4000px. Resize first, then compress for maximum savings.

Use percentage for proportional scaling

Type 50% to halve both dimensions at once - useful for quickly making a batch of images half their original size.

WebP output at 80% quality is ideal for web

Switch output to WebP and use an 80% quality slider - files are 30-50% smaller than JPEG with identical visual sharpness.
