Questions

Convert JPG to PNG FAQ

Will converting JPG to PNG make the file larger?
Yes, PNG files are typically larger than JPEGs because they use lossless compression and can include extra data like transparency channels. The exact size increase depends on the image content and whether alpha transparency is enabled.
Can I convert a JPG with text to PNG and keep it sharp?
Converting to PNG preserves the existing pixel data, so text that was clear in the JPG will remain at the same resolution. If you need sharper text, you may want to start from a higher-resolution original or a vector source.
Do I lose image quality when converting JPG to PNG?
No, PNG uses lossless compression, so the pixel data from the original JPG is preserved exactly as-is. Any compression artifacts already present in the JPG will remain in the PNG.
Is it safe to upload personal photos to these online converters?
These tools run in the browser and do not appear to upload images to a server based on the provided material, but if you are handling sensitive photos, check the site's privacy policy or consider using offline software.
Can I add transparency to a JPG that doesn't have any?
Yes, both tools offer an option to generate a transparency channel during conversion, which makes areas of the image transparent that were previously solid colors. The results vary depending on the image content.
