PNG to JPG Converter

Convert PNG images to JPG, with control over quality and the background colour behind transparent areas.

This tool runs entirely in your browser. Your data is never uploaded, never stored, and never leaves your device.

JPG is the format almost every website, email client and photo service accepts, and this produces one from a PNG — including a choice of what colour fills any transparent areas, because JPG cannot store transparency at all.

How to use it

1Drop in your PNG.
2Pick a background colour for transparent areas (white is the usual choice).
3Set the quality, then download the JPG.

Example

Input: A PNG screenshot with a transparent corner
Output: A JPG where that corner is filled with your chosen background colour

This is the one thing to know: transparency is not preserved. If you need it, convert to WebP instead.

What happens to your data

This tool runs entirely in your browser. Your input is never uploaded to a server, never stored, and never logged. The conversion is done by drawing to a canvas and re-encoding, so quality depends on your browser's JPEG encoder rather than on any server.

PNG is the right format for a screenshot and the wrong one for a photograph. Converting PNG to JPG usually happens for one of two reasons: a file is far larger than it needs to be, or something will only accept a JPEG.

This changes PNG to JPG in your browser, with control over quality and — the part most converters get wrong — over what colour goes behind any transparent areas.

The reason to convert is almost always somebody else's software. Photo printers, older editors, upload forms with a fixed whitelist and a surprising number of internal systems still expect JPEG and reject anything that is not. The reason not to convert is quality: PNG is lossless and JPEG is not, so this is a one-way door.

That trade is worth making for photographs and worth avoiding for screenshots, logos and diagrams, which JPEG handles badly and often stores no more compactly than PNG did.\n\nPNG to JPEG is the same conversion spelled properly \u2014 the two extensions name one format \u2014 and it is PNG to JPG free here with no account and no watermark.

How it works

Toolvore decodes the PNG, fills the canvas with your chosen background colour, draws the image over it and encodes the result as a JPEG. That fill matters because JPEG has no transparency: a converter that skips it leaves transparent pixels as black, which is why a logo converted elsewhere so often comes back on a black square. Nothing is uploaded — the conversion is done by the same graphics stack your browser uses to draw the page. Transparency is the part that surprises people: JPEG has no alpha channel, so any transparent pixel has to be given a colour, and that colour is white. A logo drawn to sit over any background arrives sitting in a white rectangle. Where that matters, WebP is the better target — it keeps transparency and is usually smaller than either PNG or JPEG.

Common use cases

Converting a PNG screenshot to JPG so it takes far less space
Meeting an upload requirement that accepts JPEG but not PNG
Flattening a transparent logo onto white for a document or a slide
Reducing the size of image-heavy pages by changing format
Preparing photos exported as PNG for a service that expects JPG

Frequently asked questions

How do I convert PNG to JPG?＋

Drop the PNG in, choose a quality level and a background colour for any transparent areas, then convert and download. There is no signup and no watermark.

What happens to transparency?＋

JPEG cannot store it, so transparent pixels have to become a solid colour. You choose which one — white by default. Converters that do not ask usually leave those areas black, which is why a logo can come back looking wrong. If the transparency itself matters, WebP is the better target: it keeps an alpha channel and is usually smaller than either PNG or JPEG.

Will the image lose quality?＋

JPEG is lossy, so some detail is discarded — that is how the file gets smaller. The quality slider controls how much. For a photograph the difference is usually invisible at high quality; for text or sharp lines a PNG is genuinely better and worth keeping. It is also permanent: converting the JPG back to PNG afterwards recovers nothing, it just stores the degraded version losslessly.

Is a JPG smaller than a PNG?＋

For photographs, dramatically — often by ten times or more. For screenshots, flat colour and text it can go the other way, because PNG compresses large areas of identical colour extremely well.

Is my file uploaded?＋

No. The conversion happens in your browser and the image never leaves your device.

When is PNG actually the better format to keep?＋

Whenever the image is made of flat colour and hard edges — logos, icons, diagrams, screenshots of text. PNG is lossless and handles large areas of identical colour efficiently, while JPEG was designed for photographs and puts faint smudges around sharp boundaries. A screenshot saved as JPEG often looks worse and is not much smaller.

Does the JPG keep the original's metadata?＋

Treat it as not guaranteed. Conversion writes a new file, and information attached to the original — capture date, camera, colour profile, any GPS position — may not carry across. For sharing that is usually the safer outcome. For archiving it is not, so keep the original rather than replacing it.

What quality setting should I actually use?＋

For photographs, high quality is almost always right: the file is a fraction of the PNG and the loss is invisible at normal viewing size. Dropping the slider low is worth it only when a hard size limit forces it, and the first thing to try instead is reducing the image's dimensions — halving the width removes three quarters of the pixels, which does more for size than any quality setting and costs less in visible detail.

Should I use WebP or AVIF instead?＋

If the destination accepts them, often yes. Both compress better than JPEG at the same visual quality and both keep transparency, which JPEG cannot. The reason JPEG is still the default answer is not technical merit but reach: it is the one raster format that thirty years of software, printers and upload forms all agree on.

Is there any difference between .jpg and .jpeg?＋

None at all — they are the same format under two spellings. The three-letter version survives from an era when MS-DOS could not store a longer extension, and it stuck. If a system insists on one, renaming the file is enough; nothing inside it needs to change.

Why is my PNG so large to begin with?＋

Usually because of what produced it. A screenshot from a high-resolution display holds four times the pixels of the window you saw, and a PNG stores all of them exactly, with no loss anywhere. Photographs are the worst case: PNG has no way to discard the fine variation between neighbouring pixels that a photograph is mostly made of, so it stores every one. That is precisely the case JPEG was designed for, and why the saving is so large here and so small on a logo.
