About this tool
PNG is a lossless format ideal for screenshots, graphics, logos and images that need a transparent background. This tool re-encodes your JPG or WebP images to PNG entirely in your browser using the Canvas API — no files leave your device. The output PNG retains the full resolution and color of the original. Because PNG is lossless it is usually larger than JPG; if you need a smaller file for the web, consider using our Image to WebP converter instead.
Frequently asked questions
Why convert JPG to PNG?+
PNG supports transparency and is lossless, making it better for graphics, logos, and images you plan to edit further. JPG uses lossy compression that degrades quality on each re-save.
Will my JPG image have a transparent background after converting to PNG?+
No — JPG doesn't store transparency data, so the converted PNG will have the same opaque background as the original JPG.
Is PNG or JPG better for photos?+
JPG is usually better for photos because it produces much smaller files. Use PNG for screenshots, graphics, logos, or images with sharp edges and flat colors.
Can I convert JPG to PNG without losing quality?+
Yes — PNG is lossless, so the conversion preserves all detail from the original JPG. No further quality is lost in the PNG encoding step.
