Question 1

Is this PNG to JPG converter free?

Accepted Answer

Yes, all of it, and there is no account to make. Any number of files at once, the quality setting, the background color, resizing, the folder picker and the ZIP download are simply there. Nothing on this page is a sample of something paid.

Question 2

Can I batch convert PNG to JPG?

Accepted Answer

Yes. Drag in as many PNGs as you like and they convert one after another, each with its own row, its own preview and its own download, then come back together as a single ZIP if you want them that way. To batch convert PNG to JPG at a particular quality, move the quality slider once and the whole list is rewritten at the new setting. There is no count you have to stay under, because your own processor is doing the work.

Question 3

Can I convert a whole folder at once?

Accepted Answer

Yes. Press "Choose a folder" and pick the folder itself instead of the files inside it, which is what you actually have after exporting graphics or saving a run of screenshots. Everything in it that could be an image joins the queue, and the stray text files and hidden entries a folder collects are left alone.

Question 4

Can I convert JPG to PNG here too?

Accepted Answer

Yes, on this page and in the same drop. The direction is read from each file, so a JPG becomes a PNG without you changing anything, and a folder holding both kinds comes back with each file swapped. If everything has to end up as one format instead, the direction control under the file list does that. One thing to expect: the PNG will be bigger than the JPG was, often much bigger, because PNG stores every pixel exactly and cannot leave anything out.

Question 5

What happens to a transparent PNG background when I convert it to JPG?

Accepted Answer

It becomes a solid color, because a JPG has no way to store transparency at all. Every pixel in a JPG has a color, so the see-through parts have to be given one. Here you choose which: white to begin with, black, or any hex value you like. The preview next to each file shows the flattened version rather than the original, so a logo that is about to arrive on a white box is visible before you download it. If the transparency has to survive, keep the PNG or convert to PNG instead.

Question 6

Will converting JPG to PNG give me a transparent background?

Accepted Answer

No, and no converter can do it. A JPG has no alpha channel, so the transparency was never in the file. There is nothing to recover, and the PNG that comes out has the same solid background the JPG had, just stored losslessly. What you are after is called a background remover, not a JPG to PNG transparent converter: it works out which pixels are the subject and which are behind it, then deletes the rest. That is a guess about the picture's content rather than a format conversion, which is why it is a different tool.

Question 7

Will converting PNG to JPG lose quality?

Accepted Answer

Some, and the reason is worth being straight about. JPEG is a lossy format, so writing one always throws detail away. At the default quality of 92 that loss is not visible at normal viewing sizes, and you can push the slider to 100 for as little of it as possible. If you need the conversion without losing quality at all, the honest answer is that a JPG cannot give you that, and the file to keep is the PNG. What the slider is really for is making the trade deliberate: drag it down and watch each file's size in the list until the result is small enough for wherever it is going.

Question 8

Why did my PNG get bigger when I converted it to JPG?

Accepted Answer

Because JPEG is bad at exactly what PNG is good at. Large areas of one flat color and hard edges, which is what a screenshot, a logo, a chart or anything with text is made of, compress beautifully in PNG and cost JPEG a lot of bytes just to approximate. Photographs are the other way round. If the file grew, that is the picture telling you it wanted to stay a PNG, and the only good reason to convert it anyway is that something on the other end insists on JPG.

Question 9

Can I just rename a .png file to .jpg?

Accepted Answer

No. Renaming changes the label on the file, not the bytes inside it, so what you have afterwards is a PNG with a misleading name. It survives for a while because most viewers ignore the extension and read the file's real header, which is exactly why the trick looks like it worked. Then an upload form, a printer or an older program checks the format properly and rejects it. Converting rewrites the pixels as JPEG data, which is a different thing entirely. Drop a renamed file here and the row for it says what it really is.

Question 10

Does this upload my images anywhere?

Accepted Answer

No, and there is no server here to upload them to. Your browser reads each file, draws it and writes the new one, all on your own machine, so the files never become part of a request. If you would rather check than take that on trust, open your browser's network tab while you convert and watch nothing happen.

Question 11

What happens to the EXIF data and GPS location?

Accepted Answer

It comes off. A JPG straight out of a camera or a phone carries the date, the camera model, the exposure and often the coordinates of where you were standing, and none of it survives the conversion in either direction. That is the safe default rather than a setting, because the pipeline that redraws the picture has nowhere to put it. If you need the metadata kept, the file to send is the original. If stripping it was the point, that has already happened.

Question 12

How do I convert PNG to JPG on a Mac?

Accepted Answer

For one file, macOS does it without a browser: open the PNG in Preview, then File, then Export, and choose JPEG in the format menu. For several, Finder can do it through right-click, Quick Actions, Convert Image. Come back here when you want to set the quality yourself, when you need to choose what color replaces a transparent background, or when the batch is large enough that you would rather watch a progress bar than a Finder dialog.

Question 13

How do I convert PNG to JPG on Windows?

Accepted Answer

Paint handles a single file: open the PNG, then File, then Save as, then JPEG picture. The Photos app offers something similar under Save as a copy. Neither lets you set the quality, and neither tells you what is about to happen to a transparent background. That is what this page adds, along with a whole folder in one pass.

Question 14

How do I convert PNG to JPG on an iPhone?

Accepted Answer

This page works in Safari on a phone, so the quickest route is here: tap the drop area, choose Photo Library, and the JPG lands in Files when you download it. If you would rather stay in iOS, the Shortcuts app has a Convert Image action that writes JPEG, and it is worth saving as a shortcut if you do this often. What does not work is renaming the file in Files, for the reason in the renaming answer above.

Question 15

Do I need to download or install anything?

Accepted Answer

No. This is a web page rather than a program, so there is nothing to install and nothing left behind when you close the tab. Load it once and it keeps working with the connection off, which is the honest answer for anyone who came looking for an offline converter.

Question 16

How many files can I convert, and how big can they be?

Accepted Answer

Any number, at any size your device can hold. Nothing here counts your files, because there is no server paying for the work. Two go through at a time so the tab stays responsive and no more than two full-size images sit in memory at once, and a folder of several hundred screenshots is an ordinary job. A file that genuinely exceeds what the browser can decode fails on its own row while the rest of the batch carries on.

Question 17

What's the difference between PNG and JPG?

Accepted Answer

PNG is lossless and can store transparency; JPG is lossy and much smaller for photographs. At its core that is the whole of it. The practical version: if a camera took the picture, JPG. If it was drawn, rendered or captured off a screen, PNG. Text and hard edges go mushy and grow halos in a JPG, while a photograph saved as a PNG is five to ten times the size for no visible gain. The table above these questions sets the two side by side.

Question 18

Is JPG the same as JPEG?

Accepted Answer

Yes, the same format exactly. JPEG is the name of the standard and of the committee behind it; .jpg is the three-letter version of the extension from the days when a filename could not hold more. Both are accepted here, along with .jpeg and .jfif, and what comes out is named .jpg because that is what nearly everything expects. So png to jpeg and png to jpg are one job, and jpeg to png is the same as jpg to png.

Question 19

Why do the colors look slightly duller after converting?

Accepted Answer

If the original came off a recent iPhone, iPad or Mac screen, it may be tagged Display P3, a wider set of colors than the sRGB nearly everything else assumes. What gets written here is sRGB, which is what makes the file open correctly everywhere, and the very most saturated colors in a P3 original have nowhere to go inside it. Most images are sRGB already and nothing changes at all. Where a wider profile is found, the row for that file says so rather than leaving you to wonder, and if the colors matter more than compatibility, keep the original.

What is being compared	PNG	JPG
Transparency	Yes, and per pixel, so edges fade out cleanly	None. Every pixel has a color
Compression	Lossless. What goes in comes out	Lossy. Detail is discarded to save space
Good at	Screenshots, logos, icons, text, flat color, sharp edges	Photographs, and anything with gradual shifts in tone
A 12-megapixel photo	20 to 40 MB	2 to 5 MB at quality 92
