JPG to PNG
Convert JPG or JPEG images to lossless PNG. 100% browser-based — your image never leaves your device.
How JPG to PNG works
Drag a .jpg or .jpeg file into the drop-zone. Your image never leaves the browser.
The image is decoded natively by your browser and re-encoded as lossless PNG on an HTML5 canvas.
Get a pixel-perfect PNG that preserves every detail of the source.
Frequently asked
Why convert JPG to PNG?+
PNG is lossless and supports transparency. It's ideal for logos, screenshots, and images that will be further edited.
Will the file size be larger?+
Usually yes — PNG is lossless so it can't compress photos as tightly as JPG. Expect 2–5× the original size for photographic content.
Is the image uploaded to a server?+
No. Conversion runs entirely in your browser using a Canvas element. Nothing is uploaded.
Any size limit?+
Only limited by your device's memory. Modern laptops handle images up to 100 MP without issue.
Pro drops a folder of images and returns one ZIP of .png files — same engine, same privacy, still zero uploads.
