Up to 20 MB per file · Up to 20 megapixels
Images are processed in your browser. Reducing the width preserves the aspect ratio.
JPG replaces transparency with white. GIF is converted to a still image of its first frame.
How to use
- Choose an image in the required source format. The output format is preselected.
- Optionally reduce the maximum width and adjust quality, then convert and download the result.
Formula and conversion method
New height = original height × (new width ÷ original width)
Worked example
1200×800 JPG → keep dimensions → 1200×800 PNG
Things to know
Saving as PNG does not recover detail already lost in JPG. It does not remove the background, and file size may increase.
