FAQ
What happens to transparency when converting PNG to JPG?
JPG does not support transparency. Transparent areas are filled with white. Use PNG or WebP to keep alpha.
Does JPG to PNG make an image sharper?
No. Conversion cannot restore detail already lost by JPG compression, and PNG may be much larger.
Do you support GIF, HEIC, SVG, or RAW?
The first version supports static JPG, PNG, and WebP files only.
What each format is good at
JPG was built for photos: it compresses continuous tone efficiently, stays small, and has the widest compatibility, at the cost of being lossy with no transparency. PNG is lossless and supports a transparent background, which suits icons, screenshots, and line art — content with large flat areas and sharp edges — but photos saved as PNG become huge. WebP is the newer format that bridges the two: it compresses photos as efficiently as JPG and preserves transparency like PNG, usually smaller than both at the same look, at the cost of a few old programs not recognising it.
So "which format should I convert to" is really asking "what will I do with it next." For the web and loading speed, WebP; to open in old software or at a print shop, JPG; for a transparent background or repeated editing, PNG.
Conversion cannot recover lost quality
A common myth is that converting JPG to PNG makes an image sharper. The opposite is true: the JPG discarded information the first time it was saved, and converting to PNG only stores the current pixels — compression noise included — losslessly. The lost detail does not return. Conversion changes only the container, not the quality. Likewise, converting a low-quality WebP to JPG will not improve it, only add a slight second-pass loss.
Where transparency goes
The thing to watch when converting is the alpha channel. Going from PNG or WebP to JPG, which has no alpha channel, fills every transparent area with white — so an icon meant for a dark background comes out with a jarring white box. To keep transparency while cutting size, convert between PNG and WebP rather than to JPG.
