What to expect when converting JPG to PNG
A 1 MB JPG typically becomes 2 – 5 MB as PNG.
Quality: Lossless — the conversion does not improve quality (any JPG compression artifacts in the original are preserved exactly).
Best for: adding transparent backgrounds, layering in design software, archival.
Avoid when: you only need the photo as-is and want a smaller file.
Tip: PNG can't undo JPG artifacts. If the source has visible compression noise, it will be preserved at higher fidelity in PNG — bigger file, same flaws.
JPG to PNG — The lossy-to-lossless conversion — mostly for editing
JPG → PNG is the most-searched image conversion. The most honest use case: you have a JPG that you're about to edit (logo work, product-photo cleanup, screenshot annotation), and you want subsequent edits to be lossless — every re-save of a JPG loses more information. Note: converting an already-compressed JPG to PNG does not recover the lost quality; it just prevents further degradation. File size will typically 2-4× for photographic content.
Converting JPG to PNG: what you gain and what you don't
JPG-to-PNG conversion decodes the lossy JPG data and re-wraps it in a lossless PNG container. The resulting PNG preserves every pixel of the decoded JPG exactly — but it cannot recover detail that the original JPG encoding discarded. The file will be 3-8× larger with zero visual improvement. What you do gain: a format that won't degrade further on re-save, the ability to add transparency in an editor, and compatibility with workflows that require lossless input.
Convert JPG to PNG when you need to edit the image in software that re-saves on every operation (preventing accumulating JPG artifacts), when you need to add a transparent background, or when a system specifically requires PNG input. Don't convert if your goal is to "improve quality" — the quality ceiling is set by the original JPG, and no format change can raise it.
