Your files are processed by your own browser and never sent to a server.
Almost everyone arriving here has a file that is too big for somewhere it needs to go. A design tool exported a PNG, a phone screenshot went into a document, a scanner saved at its default, and now an email bounces or an upload form says the limit is 5 MB.
For a photograph, JPG is simply the right format and PNG never was. PNG keeps every pixel exactly, which is what you want for a screenshot of text or a logo with hard edges, and is close to the worst possible choice for a picture of a face or a landscape. Converting one usually takes eighty or ninety per cent off the file with nothing you could point to in a side-by-side comparison.
The one thing to check before you press the button is transparency, because JPG has none and cannot be talked into it. If your PNG has a see-through background, it comes out filled with the colour set in the panel, white by default. For a logo destined for a coloured page, that white box is what you will see, and PNG to WebP is the conversion you actually wanted.
How to convert PNG to JPG
- Drop your PNG files onto the box above, or paste them with Ctrl+V.
- Save each file from its tile, or take them all at once.
What changes
Transparency is lost
JPG cannot store see-through pixels, so anything transparent is filled with the colour you pick in the panel, white unless you change it.
Detail is discarded
PNG keeps every pixel exactly and JPG does not, so the encoder throws away the fine detail your eye is worst at noticing. At high quality this is invisible.
PNG and JPG side by side
| PNG | JPG | |
|---|---|---|
| Where it came from | 1996, designed as a free replacement for GIF | 1992, from the Joint Photographic Experts Group |
| Throws detail away | No, every pixel is kept | Yes |
| Transparency | Yes | No |
| Where it opens | Everywhere, without exception, since the late nineties | Everywhere, on everything, including hardware old enough to vote |
| Best at | Screenshots, logos, diagrams and anything with text or hard edges in it | Photographs, and anything going somewhere you cannot predict |

Questions about PNG to JPG
Why did my transparent background turn white?
Because JPG has no way to store transparency at all, and something has to go where the see-through pixels were. The panel fills them with white unless you pick another colour, which is the least surprising default but not always the right one: a logo going onto a dark page needs that colour set to match, or it arrives in a white rectangle. If the background needs to stay transparent, JPG is the wrong target and WebP or AVIF is the right one.
How much smaller will the file actually get?
It depends entirely on what is in the picture, and the range is enormous. A photograph saved as PNG commonly falls by ninety per cent or more, because it was stored in a format built for the wrong kind of image. A screenshot of a spreadsheet, a logo or a line diagram may fall very little, and can even grow: PNG is genuinely efficient at flat colour and hard edges, and JPG is not. If yours is the second kind, converting is rarely worth it.
Will I be able to see the difference?
On a photograph, at the default quality, almost certainly not. On text and hard edges you may: JPG works in eight-by-eight blocks and puts its errors where contrast is highest, so black text on white gets a faint grey halo that a screenshot makes obvious. This is the practical rule for choosing between them. Pictures of the world go to JPG; pictures of a screen stay as PNG.
Can I convert it back to PNG afterwards?
You can produce a PNG, but not the one you started with. Going to JPG discards detail permanently, and converting the result back gives you a lossless copy of the damaged version, usually larger than the JPG and no better looking. Keep the original PNG if you might need it. Round-tripping through JPG repeatedly is how an image slowly turns to mush over the course of an email thread.
