Private image processing
Enter a target width or height and lock the aspect ratio to prevent distortion.
Decoding, resizing, and encoding happen in this browser. The site does not retain the original or result after you close the page.
Choose or drop a PNG, JPEG, or WebP image.
Set the target size, format, and quality. Lock the aspect ratio to prevent distortion.
Process the image, compare the file size, and download the result.
No. Processing happens locally in your browser and the file is not sent to a backend.
PNG is lossless, so browser export does not expose the lossy quality control available for JPEG and WebP. Choose WebP when a smaller file is the priority.
Upscaling, choosing lossless PNG, or re-encoding an already optimized image can increase its size.
