Free Online JPG to PNG Converter
Transform your JPEG images into high-quality PNG files instantly without leaving your browser. Because PNG uses lossless compression, every pixel stays exactly as it appeared in the original source. This format also brings transparency support to the table, making it perfect for logos, web graphics, and screenshots where sharp edges are essential. Simply drop your files in, convert them in a batch, and save your results in seconds.

How to Convert JPG to PNG
Get your images converted in three easy steps. Start by dragging your JPG files directly into the workspace or clicking to upload several at once. Once you hit the Convert button, your browser handles the heavy lifting locally, rendering each image to a canvas before exporting it as a crisp PNG. Finally, check your results in the preview panel and grab your new files individually or as a complete batch. Since everything happens on your machine, your data never touches a remote server.
Batch Processing for Multiple Images
Efficiency is key, so feel free to drop an entire folder or select multiple files at once. The tool processes every image independently, giving you a clear breakdown of file sizes and compression results for each one. If you missed a few, just add more to the queue and keep converting until your project is finished.
Image Preview with Zoom and Rotation
Once your files are ready, click any entry to pull up a full-sized preview. You can use the built-in controls to zoom, rotate, or flip your images to ensure everything looks perfect before you download. The checkerboard background in the viewer makes it easy to identify transparent regions in your new PNG files.
Online JPG to PNG Converter with Transparency Support
Transparency is a major reason to choose PNG over standard JPEGs. Enabling the transparent background option preserves the alpha channel, allowing you to overlay your graphics on any surface without a clunky white box. This is a lifesaver for web designers and presenters who need clean edges. If you prefer a solid look for your photos, just leave the option unchecked to fill the background with clean white.
Lossless Quality Preservation
Expect nothing less than perfect pixel fidelity. By drawing your original JPG to a high-resolution canvas, this tool exports PNGs that retain every detail without the quality loss associated with standard JPEG compression. While JPEGs discard data to save space, these PNGs keep everything intact, giving you a master file that stays sharp through future edits.
No File Size Limits
Forget about restrictive upload limits or annoying timeouts. Since the Canvas API handles all the processing right in your browser, you can convert massive panoramic shots and high-resolution photos with ease. Your only real limit is your device memory, which is more than enough for images up to 50 megapixels on almost any modern computer or phone.
Free JPG to PNG Converter Runs Entirely in Your Browser
Your privacy is a top priority, especially when handling personal photos or sensitive documents. This tool runs entirely through your browser's local APIs, meaning no data ever travels to an external server and no accounts are needed. Your images vanish from memory the moment you close the tab. You can even use the converter offline once the page is loaded, as it requires zero server communication to function.
Additional JPG Conversion Formats
This workspace goes beyond simple PNG conversion by supporting five additional formats. You can create optimized WebP files for faster websites, 256-color GIFs for legacy support, or uncompressed BMP files for industrial applications. It also generates ICO files for website favicons and wraps your JPEGs in SVG containers for specialized design workflows that require vector wrappers.
