JPG / JPEG files only — unlimited files, unlimited size
A JPG to PNG converter transforms JPEG images into PNG format. Unlike JPEG, PNG uses lossless compression — meaning no image data is lost during the conversion. PNG also supports transparency (alpha channel), which JPEG does not. This makes PNG ideal for logos, graphics, screenshots, and images that need crisp edges or transparent backgrounds. This free online converter processes everything in your browser using the Canvas API — your images are never uploaded to any server, making it completely private and fast. It handles batch processing, so you can convert dozens of images at once by dragging and dropping. An optional transparency feature lets you pick a specific color (like white or green) and make all pixels of that color transparent in the output PNG, which is useful for quick background removal.
Toggle "Make color transparent" if you want to remove a specific background color. Pick the color using the color picker and adjust the tolerance slider to control how closely pixels must match.
Drag and drop one or multiple JPG/JPEG images onto the drop zone, or click to browse your files. You can also paste an image from your clipboard with Ctrl+V.
Review the converted files showing original and new sizes. Download images individually by clicking the download icon, or use "Download all" to save the entire batch at once.
