JPG to PNG Converter: Add Transparency and Lossless Detail
JPG is great for small, shareable photos, but it can't hold transparency and loses a little quality every time it's re-saved. ConvertBrio's JPG to PNG converter turns your JPG into a lossless PNG in seconds, which is the format you want before editing an image further, placing it on a colored background, or using it as a logo or icon.
When to Convert JPG to PNG
Convert to PNG whenever you need an alpha (transparency) channel — for example, cutting a logo out of its background — or whenever you're about to edit an image repeatedly and want to avoid the generation loss that comes from re-saving JPGs. PNG is also the safer choice for screenshots, diagrams, and anything with sharp text or hard edges, since JPG's compression can introduce blur and artifacts around fine detail.
How the Conversion Works
Upload your JPG and ConvertBrio decodes it and re-encodes it as a PNG, preserving every pixel exactly. Because JPG doesn't store transparency to begin with, the output PNG will have an opaque background unless you remove it separately — the conversion itself is about format and quality, not automatic background removal.
File Size to Expect
PNG files are typically larger than the JPG they came from, since PNG doesn't discard data the way JPG's lossy compression does. For photos with a lot of detail or texture, expect the PNG to be several times the size of the original JPG — that's the normal trade-off for lossless quality.

JPG to PNG FAQ
Common questions about converting JPG images to PNG.
Does JPG to PNG add transparency automatically?
No. JPG files don't store transparency, so converting to PNG produces an opaque image with the same appearance. PNG simply gives you a lossless format to build on, such as before editing or adding transparency in an image editor.
Why is my PNG so much bigger than the original JPG?
PNG uses lossless compression, which preserves every pixel instead of discarding detail the way JPG does. That accuracy comes at the cost of a larger file — it's expected, not a sign of a problem.
Is PNG better than JPG?
Neither is universally better — PNG is best for graphics, logos, and anything needing transparency or lossless detail, while JPG is better for photos where small file size matters more than pixel-perfect accuracy.
