About ImageSizeChanger

ImageSizeChanger provides straightforward web tools for scaling photo dimensions, reducing file weight in kilobytes (KB) or megabytes (MB), and converting between common raster file formats (JPG, PNG, WebP).

Why We Built It

People frequently need to resize a photo for a social media banner, compress a scanned document under a 100 KB limit for a job portal, or convert a PNG screenshot to JPG without installing bulky software or registering an account.

Many online tools require account signups or upload your personal images to remote servers. We built ImageSizeChanger to solve these daily tasks cleanly directly inside your web browser.

What You Can Do

• Resize Pixel Dimensions: Set exact width and height values in pixels or percentages.
• Proportional Aspect Ratio Lock: Maintain natural visual proportions to prevent image distortion.
• Target File Size Compression: Specify an exact target limit (e.g. 50 KB or 1 MB) to meet strict submission requirements.
• Format Conversion: Convert files between JPG, PNG, and WebP formats.
• Batch Processing: Select and process multiple image files simultaneously.

Our Privacy Approach

Privacy is at the core of our technical architecture. ImageSizeChanger uses HTML5 Canvas technology to perform client-side image processing. Your selected image files stay inside your local browser memory and are not uploaded to our server.
