Frequently asked questions
Which format is better for a BMP screenshot?
PNG usually suits screenshots with sharp text, diagrams, or solid colors. JPG can suit photographic content, but its compression can introduce visible artifacts around letters and lines.
Will my bitmap dimensions change?
Format conversion keeps the decoded image dimensions. Use the separate Resize Images tool if you also need to change the width or height.
Are my files uploaded or stored?
The conversion happens in your browser. Keep the original files and save your downloads before closing the page. Learn how local processing protects your images.
