Free JPG to PNG Converter – Convert JPG Images to PNG Online
Need to convert a JPG image into PNG format? Our free online JPG to PNG converter makes it fast, easy, and completely lossless. JPG is a compressed image format perfect for photographs and everyday images — but it uses lossy compression, which means quality is slightly degraded every time the file is saved. PNG, on the other hand, is a lossless format that preserves every pixel exactly as it was captured. Converting JPG to PNG is ideal when you need to edit, archive, or publish an image without ever worrying about further quality loss. Simply upload your JPG files, choose your output dimensions, and download perfect PNGs in seconds — all from your browser, no software required.
Using the converter is simple. Drop one or more JPG files into the zone, or click to browse and pick several at once. Each file is processed in sequence, and every one appears as its own row with a thumbnail, its original size, its new PNG size, and its pixel dimensions. You can set a fixed target size, leave Width and Height blank so each JPG keeps its own native size, and use the 2x, 3x, or 4x scale multiplier to generate high-resolution output for retina displays or print. When everything is ready, download PNGs individually or grab the whole set as a single ZIP.
Why Convert JPG to PNG?
PNG is the preferred format for graphics that need to stay sharp and unaltered. Unlike JPG, PNG uses lossless compression, so no pixel data is ever discarded. This makes PNG the go-to format for screenshots, logos, UI mockups, text-heavy images, and any file that will be edited repeatedly. Every time you save a JPG, the compression algorithm throws away a little more image data to keep the file small — after several rounds of editing and re-saving, artifacts and blocky patches start to appear. PNG avoids that entirely. It also supports full transparency, so once your image is in PNG, you can open it in any editor and add transparent regions, remove backgrounds, or place it over other graphics without ugly white boxes.
Batch Convert a Whole Photo Folder
Photographers, designers, and marketers often need to convert dozens or hundreds of JPG files at once — a client photo shoot, a folder of screenshots, a product catalogue, or an export from a camera. Converting them one by one is slow and error-prone. This tool accepts multiple JPGs in a single drop and processes the entire batch automatically. Each file is decoded independently, its native dimensions are detected, and the PNG is rendered at the target size you selected — either a fixed dimension you provide or the file's own native size multiplied by the scale value. When everything is done, download each PNG separately or grab the whole set in one ZIP file named jpg-to-png-converted.zip. Size, aspect ratio, and scale settings apply to the entire batch, and the live summary bar shows how many files are done and the total output size.
Private, Fast, and Completely Free
This tool runs entirely inside your browser using the HTML5 Canvas API. Your JPG files never leave your device and are never uploaded to any server, so your photos and designs stay completely private. It works on Windows, Mac, Linux, Android, and iPhone, and there are no file size limits, no watermarks, and no signups. Whether you are a photographer archiving your work, a designer preparing assets for editing, or a marketer converting images for a website, our JPG to PNG converter delivers professional-grade results with a single click.
