How it works
- Drop your .png files onto the bench, or pick them from your device.
- Choose a quality level, and the colour that transparent areas should become.
- Press Convert, then download the JPGs one by one or as a single .zip.
The one thing to decide before you convert is what should happen to transparency. PNG can store a fully see-through background; JPG cannot store transparency at all. Every transparent pixel has to become some solid colour, and the converter has to pick one. White is the usual answer because most documents and web pages are white, but a logo meant to sit on a dark header will look wrong with a white box around it. Set the background colour to match wherever the image is going.
The second thing to know is that PNG and JPG are good at opposite kinds of picture. PNG stores flat areas of colour extremely efficiently, which is why screenshots, charts, diagrams and logos are usually PNG. JPG works by blurring away fine detail your eye is unlikely to miss — wonderful on photographs, unkind to sharp edges. Convert a screenshot full of small text to JPG and you will see faint smudges around the letters. Convert a photograph and you will likely cut the file to a fifth of its size with no visible difference.
So the honest rule is: photographs saved as PNG are the ideal candidates here, and often shrink dramatically. Screenshots and graphics usually should stay PNG unless something is forcing your hand — an upload form that only takes JPG, a print shop, an old system. If that is your situation, push the quality slider up to 90 or higher to keep the text as sharp as JPG allows.
Questions people ask
- What happens to the transparent parts of my PNG?
- They are filled with the background colour you choose, because JPG has no way to store transparency. Pick the colour of the page or slide the image will sit on, otherwise you will see a visible rectangle around the artwork.
- Why does the text in my screenshot look fuzzy now?
- JPG compresses by softening fine detail, and small text is nothing but fine detail. Raising the quality slider reduces the effect but never removes it. For screenshots with text, PNG really is the better format.
- How much smaller will the file get?
- For photographs, commonly five to ten times smaller. For flat graphics and screenshots the saving is much smaller, and occasionally the JPG comes out larger than the PNG it came from.
- Which quality setting should I pick?
- Around 90 is a safe default for anything with edges or text. For photographs that are just being viewed on screen, 75 to 85 saves a lot more space and is very hard to tell apart from the original.
- Can I turn the JPG back into the original PNG later?
- Not really. The conversion discards detail permanently and fills in the transparency for good. Converting back gives you a PNG of the degraded image, not the file you started with, so keep the original.
- Do my files leave my computer?
- No. Your browser does the decoding and encoding on this page. There is no upload step and no server copy of your images.
