How to convert JPG to PNG
Drop your JPG onto the box above, or click to choose one. You will see the original size and dimensions, then one click produces the PNG and shows its new size before you download. The work happens on your device, so even large photos convert in a moment and nothing is uploaded.
When JPG to PNG is the right move
JPG is built for finished photos, not for files you keep working on. Every time a JPG is edited and saved, it loses a little more quality, a slow drip of damage editors call generation loss. Converting to PNG stops that drip: PNG saves losslessly, so the tenth edit looks exactly like the first. That makes PNG the right container for screenshots you will annotate, graphics you will resize repeatedly, and images headed into design tools, presentation software or print layouts.
PNG is also the safer hand-off format between programs. Some editors, OCR tools and upload pipelines quietly re-compress JPGs on import, softening text and edges. Sending a PNG master avoids that quiet damage and keeps sharp edges on logos, diagrams and interface captures exactly as you made them.
How the conversion works
Your browser decodes the JPG into a grid of pixels, exactly as it currently looks, and writes those pixels into a PNG file. Nothing is sharpened, enlarged or repaired in the process: the PNG is a perfect copy of the JPG as it stands, stored in a format that will not degrade it further. Camera metadata from the original does not carry across, so the PNG starts with a clean slate.
Quality tips for JPG to PNG
- Convert early in your workflow. The sooner a working file becomes PNG, the fewer lossy saves it suffers. Make the PNG your editing master and export JPG copies only at the end.
- Do not expect miracles on soft photos. A blurry or heavily compressed JPG stays that way as a PNG. Convert the best JPG version you have.
- Watch the file size for sharing. PNG photos are big. If the converted file is only passing through email or a form, the original JPG is usually the better attachment.
- Use PNG where edges matter. Text, line art and screenshots gain the most from PNG storage, because JPG artifacts show up first around sharp contrasts.
A worked example
A support agent screenshots an error message and saves it as a 180 KB JPG. She needs to circle the error in an editor, add arrows, and export it three times for a help article. Working from the JPG, each save would soften the small text further. She converts it to PNG here (about 950 KB), does all her editing on the PNG, and the published image stays crisp through every export.
Going the other way? The PNG to JPG converter shrinks PNGs back down for sharing, and the Image Converter handles WebP as well.
