Frequently Asked Questions
Does converting JPG to PNG make the image transparent?
No. JPG files do not support transparency. To make the background transparent, you will need to edit the image after conversion.
Why is the output PNG file sometimes larger than the original JPG?
JPG uses lossy compression, while PNG uses lossless compression. This means PNG files preserve full pixel data, which can result in larger file sizes.
Is it safe to convert private photos here?
Yes. The conversion runs locally in your browser, so your photos are never uploaded or stored.
Can I convert multiple images at once?
Yes. The tool supports bulk conversion, allowing you to convert multiple JPG files to PNG simultaneously.
Does this tool support high-resolution photos?
Yes. The canvas rendering engine handles high-resolution images, although performance depends on your browser's memory.
Will my image metadata be preserved?
Basic image dimensions and colors are preserved. Metadata like EXIF data may be stripped during the canvas redraw.
What is the recommended use case for PNG?
PNG is ideal for digital art, logos, text screenshots, and graphics that require crisp lines and transparency.
Is there a limit on daily conversions?
No. The tool is 100% free with no daily limits or restrictions.
