Convert JPEG images to lossless PNG format. Preserve quality and gain transparency support. Free, instant, no signup.
Supports JPG, JPEG and more
Files are processed locally in your browser. Nothing is uploaded to a server.
Converting JPG to PNG makes sense at three specific moments: when you need a transparent background, when an image will be edited and re-saved many times, and when a website or app only accepts PNG uploads. PNG stores every pixel exactly as received, so a JPG converted to PNG stops accumulating compression damage from that point forward — useful for logos, product photos, and screenshots that get cropped, annotated, or resized repeatedly.
One expectation to set straight: the PNG file will usually be 3 to 5 times larger than the source JPG, because PNG uses lossless compression while JPG deliberately discards image data. A 2 MB photo commonly lands between 6 and 10 MB as a PNG. That trade is worth it when quality and transparency matter, and the wrong choice when you simply need a smaller photo — for that, PNG to JPG or Image to WebP is the better direction.
The tool decodes the JPG, then re-encodes it as PNG with lossless compression. The resulting file is usually larger than the JPG (since PNG doesn't discard data), but quality is preserved exactly.
Getting Started
Drag and drop your file into the converter, or click to browse. Supports JPG, JPEG and more.
Configure output settings like quality, size, and format options. Defaults work well for most use cases.
Click "Convert" and your PNG file is ready in seconds. Free, unlimited, no account required.
Design work: place a JPG logo or graphic into a design tool and keep editing without each save adding JPEG artifacts.
Transparent backgrounds: JPG has no alpha channel, so removing a background requires a format that supports transparency — PNG is the standard choice.
Platform requirements: app stores, marketplaces, and many CMS image fields demand PNG for icons and graphics.
Archival masters: keep an editable PNG copy of a photo you will crop, resize, or color-grade later.
FAQ
No. PNG preserves whatever quality the JPG has, but cannot restore data already lost through JPEG compression. It does prevent further quality loss from resaving.
Usually yes. PNG uses lossless compression which produces larger files than JPG's lossy compression. The tradeoff is perfect quality preservation.
PNG stores images losslessly, so it keeps every pixel of your already-compressed JPG and adds PNG container overhead. A 3 to 5 times size increase versus the JPG is normal.
No. JPEG compression discards detail permanently at capture or last save. PNG preserves exactly what is left — it prevents future loss but cannot undo past loss.
Usually no. Photographs are best served as JPG or WebP, which are far smaller at the same visual quality. Reserve PNG for graphics, screenshots, and images needing transparency.
