About this tool
PNG is a lossless format, which makes it the right choice when you need to preserve exact pixel values — for screenshots, graphics with sharp edges, or images that will be edited further and re-saved multiple times without accumulating compression artifacts.
This converter decodes each JPG using your browser's image engine and re-encodes it as PNG on a canvas, keeping every pixel exactly as decoded. Because PNG is lossless, the resulting file is usually larger than the original JPG — that trade-off is inherent to the format, not a limitation of this tool.
Why use it
- Lossless output — no further quality loss
- Batch conversion of multiple JPGs at once
- No file ever leaves your device

- Free, with no watermark or signup
Frequently asked questions
Why is my PNG file bigger than the original JPG?
PNG uses lossless compression, which generally produces larger files than JPG's lossy compression, especially for photos. This is expected and is the trade-off for zero further quality loss.
Will converting JPG to PNG improve the image quality?
No — a JPG's compression artifacts, if any, are already baked into the pixels. Converting to PNG preserves those pixels exactly but can't remove existing artifacts.
Can I convert several JPGs to PNG at the same time?
Yes, drop multiple files at once; each is converted independently and can be downloaded individually or as a ZIP.
Does this tool add a watermark?
No. The output is a clean, unmodified conversion of your image with no watermark.
Is this safe for private or sensitive photos?
Yes — since conversion happens locally in your browser, your images are never uploaded or stored anywhere.
