PNG batch converter

How good it looks, not how big it gets. 85 looks the same as the PNG to most eyes.

Makes the image smaller in pixels first. This saves more than quality does.

Reduces the image size in pixels to make the file smaller.

Background

JPG cannot be see-through. Clear parts become this colour.

How it works

  1. 01

    Add your PNG files

    Drop, paste or pick any number. The files stay in this tab, and the page sends them nowhere.

  2. 02

    Choose the background

    JPG cannot be see-through. Pick the colour that goes behind the clear parts.

  3. 03

    Convert and download

    Save one file, or the whole batch as a zip. Your PNG files stay as they are.

What happens to the see-through parts

A PNG can store how see-through each pixel is. A JPG cannot. So every clear pixel has to become a real colour, and the tool has to ask you which one. No single colour is right. Pick the one that matches where the picture is going.

White suits most cases, because a logo or a screenshot with a clear background is usually headed for a white page. Pick black or your own colour when the page behind it is dark. Get this wrong and the picture still converts, but you will see a box of the wrong colour around your subject.

Size can go either way. Photos almost always shrink, often by a lot. Flat pictures may not. PNG stores a large area of one colour very cheaply. So a chart or a screenshot can come out bigger as a JPG. The queue shows the new size on every row before you save anything.

Background
White, black, light grey, near black, or any colour you pick.
Batch
No limit on files. One at a time, so memory stays flat.
Quality
1 to 100, with 85 as the default.
Originals
Never touched. Converting always writes a new file.

Frequently asked questions

Why do I have to choose a background colour?
JPG has no see-through layer. Every clear pixel in your PNG has to become a real colour. White is the usual answer, because most PNGs with clear parts are logos or screenshots for a white page. Pick black or your own colour if that suits yours better.
Will a JPG be smaller than my PNG?
For photos, almost always, and often by a lot. For flat pictures it can go the other way. PNG is very good at large areas of one colour, so a chart or a screenshot sometimes comes out bigger as a JPG. Each row shows the new size before you save.
Does converting lose quality?
Yes, a little. JPG throws away detail your eye is least likely to miss. At quality 85 most photos look the same at normal viewing size. Text and sharp lines show it first, so check those before you save a screenshot.
How many files can I convert at once?
As many as you like. Files run one at a time, so a long queue never holds a stack of decoded images in memory. Your free memory is the only real ceiling.
Do my images get uploaded?
No. Every decode and re-encode happens in this tab. The image data never leaves your device, so there is no copy to delete.
Should I use JPG or WebP?
WebP is smaller at the same quality and keeps clear parts clear. Nearly every program opens JPG, which is why people still ask for it. Use JPG when something else needs to read the file, and WebP for the web.
Are my PNG files changed?
No. Your browser reads each one and writes a separate new JPG for you to download. The file on your disk is untouched.
What happens to EXIF data?
The tool drops it. Your browser redraws the pixels on a canvas, and nothing else comes along. The output is tagged sRGB, and you cannot change either here.
Can I make the image smaller in pixels too?
Yes. Set the size to 75% or 50% and a big image is scaled down before it is encoded. That saves far more than quality alone. For an exact width and height, use the image resizer.
Does this work offline?
Yes. Once the page has loaded, converting carries on with no network connection.
