About this tool
Turns JPG files into PNG. The PNG is larger than the JPG, and it does not recover detail the JPG compression already removed. JPG uses lossy compression and has no alpha transparency. This tool fills transparent areas with white; conversion cannot recover detail lost in the source. PNG stores pixels without lossy compression and supports transparency. It suits screenshots and line art, but converting a photo to PNG can increase its file size.
Change an image to PNG, JPG, WebP, AVIF, GIF, BMP, ICO or TIFF. JPG and BMP fill transparency with white. Animated inputs and multi-page TIFFs keep only the first frame or page.
Questions
Will JPG to PNG preserve transparency, dimensions and every frame?
JPG uses lossy compression and has no alpha transparency. This tool fills transparent areas with white; conversion cannot recover detail lost in the source. PNG stores pixels without lossy compression and supports transparency. It suits screenshots and line art, but converting a photo to PNG can increase its file size. Dimensions are kept except when creating ICO sizes. Only the first animation frame or TIFF page is converted.
What happens to transparent areas?
PNG, WebP, AVIF, TIFF and ICO preserve transparency. GIF uses up to 256 colors and on/off transparency. JPG and BMP fill transparent areas with white.
Which input formats can it read?
It reads any image your browser can decode, including PNG, JPG, WebP, AVIF, GIF, BMP and ICO where supported. TIFF uses a separate decoder. Only the first animation frame or TIFF page is converted.
Does converting improve quality?
No. Converting cannot restore detail that is already lost. Converting a JPG to PNG makes a larger file with the same pixels, and converting to JPG re-compresses the image.
Is the image uploaded?
No. Conversion runs in your browser tab, so the files stay on your device.
