JPG ↔ PNG Converter

Convert between JPG and PNG. Drop images, pick a target format, download. No upload.

JPG and PNG cover most of the everyday web image work — JPG for photos and PNG when you need transparency or pixel-perfect graphics. Converterzilla converts in either direction using the browser's built-in canvas API, which means there's no upload step and no quality compromise beyond what each format inherently allows. Drop a batch of images, pick the target format, and download.

How to use JPG ↔ PNG Converter in your browser

  1. Drop your images. Drag one or many images into the drop zone, or click to pick them. JPG, PNG, WebP, GIF and BMP inputs are all supported.
  2. Choose your target format. Pick PNG for lossless output (best for screenshots, graphics with transparency) or JPG for smaller files (best for photos).
  3. Set JPG quality if needed. When converting to JPG, slide the quality control between 40% and 100% to balance file size against visual fidelity.
  4. Click Convert. Each image is decoded, drawn onto a canvas in the target format, and downloaded automatically.

Frequently asked questions about JPG ↔ PNG Converter

JPG for photos and anything where small file size matters — it's a lossy format that compresses photos beautifully. PNG for screenshots, graphics, logos, and any image that needs transparency.

JPG is lossy by design — it discards visual information that humans don't easily notice. Higher quality settings reduce the difference. PNG output is identical to the input.

Yes. Drop them in and pick PNG or JPG as the target. The tool will read any common image format your browser supports.

There's no hard cap. Conversion works on photos straight out of a 50-megapixel camera as long as your browser has enough memory.

No — going from JPG to PNG can't recover detail that JPG already discarded. The PNG output preserves exactly the JPG's pixels in a lossless container. The reverse direction (PNG to JPG) does discard detail, controlled by the quality slider.

PNG and WebP support transparent backgrounds; JPG and BMP don't. When converting a transparent image to JPG, we fill the background with white. To preserve transparency, choose PNG or WebP as the target.
