Convert JPG images to PNG format with full transparency support.
or drop JPG files here
JPG to PNG conversion changes an image from JPEG's lossy, compressed format to PNG's lossless format. The conversion itself can't recover detail that JPEG compression already discarded, but from that point forward, PNG preserves every pixel exactly with no further quality loss on repeated saves.
PNG also supports transparency, which JPEG does not — so converting to PNG is often the first step before editing an image in a tool that needs a transparent background, even though the original JPG source won't contain any transparency to begin with.
This is a browser-based converter dedicated to turning JPG images into PNG. Upload one or more JPG files, choose a quality level (Low, Medium, or High), and each image is redrawn onto a canvas and re-encoded as lossless PNG.
This is a focused, single-purpose version of image conversion — if you need to convert between other formats too, the general Convert Image tool supports 15+ formats. Everything runs locally in your browser; your files are never uploaded to a server.
Click "Select images" or drag and drop one or more JPG/JPEG files onto the upload area.
Pick Low, Medium, or High for the intermediate rendering step before the lossless PNG encode.
Click the convert/download button to redraw each JPG onto a canvas and re-encode it as PNG.
A single converted image downloads directly; multiple images download together as a ZIP file.
Converting to PNG cannot restore detail that JPEG compression already removed from the original file — the PNG will look exactly as sharp (or soft) as the source JPG, just without further compression going forward.
PNG's lossless compression generally produces larger files than JPEG for photographic content — this is expected, and is the trade-off for lossless quality preservation.
This tool only accepts files with the JPG/JPEG format specifically — PNGs, WebPs, or other formats are filtered out with an error message. Use the general Convert Image tool for other format conversions.
Converting a JPG to PNG does not add transparency — the source JPG has a fully opaque background, so the resulting PNG will too, unless you separately remove the background using a tool like Remove Background.
PNG encoding is more computationally intensive than JPEG, so converting many large images at once can take noticeably longer — let it finish rather than reloading the page.
A typical case preparing an image for further editing without repeated compression loss.
Input
photo.jpg — 1.2 MB, 1920x1080px, High quality
Output
photo.png — larger file (often several MB), same 1920x1080px dimensions, lossless from this point forward
No. Conversion happens entirely in your browser using the Canvas API. Your images are never sent to a server.
No — conversion can't recover detail already lost to JPEG compression. What it does is stop further quality loss: from the PNG onward, saves are lossless.
No, JPG source images have no transparency information, so the resulting PNG is fully opaque, just like the original. Use the Remove Background tool separately if you need transparency.
PNG uses lossless compression, which generally produces larger files than JPEG's lossy compression, especially for photos. This is a normal and expected trade-off for zero quality loss.
Yes, upload as many JPG files as you like and they'll all be converted in a single batch, downloadable as a ZIP file.
This tool is dedicated to JPG-to-PNG conversion specifically. For other formats (WebP, GIF, BMP, HEIC, and more), use the general Convert Image tool.
