Convert PNG to JPG
Turn a PNG screenshot or picture into a smaller JPG, with the quality set by you. Free, no signup.
Higher keeps more detail and makes a bigger file. 85 suits most pictures.
Leave both empty to keep the original size. Set one or both and the picture keeps its proportions; with both, it is fitted inside that box.
When PNG to JPG makes sense
PNG is lossless, and that is exactly why a photograph or a screenshot saved as PNG is often several times bigger than it needs to be. For photos, and for screenshots with gradients and shadows, JPG can bring the file down to a fraction of its size with little change you can see. That helps when a form caps uploads at 2 MB, when a web page is slow because of its images, or when you are attaching pictures to an email.
When it does not
JPG blurs hard edges. Text, thin lines, logos and flat-colour graphics are what PNG does well, and in a JPG they pick up faint halos around the edges, clearly visible at low quality. If the picture is mostly text or line art, keep the quality at 90 or above, or leave it as a PNG. A small icon can even get bigger as a JPG, because there is almost nothing for JPG to save.
Transparent areas turn white
A JPG has no transparency. Any see-through part of your PNG is filled with solid white, and there is no colour picker here to choose another. A logo with a transparent background will come out on white, fine on a white page and wrong on a dark one. If you need the transparency, stay with PNG. If you need another background colour, add it in an image editor first and then convert.
Getting under a size limit
Two controls do the work: the quality slider and the optional width and height. Start at 85 and read the converted size in the numbers under the button. If it is still too big, lower the quality in steps of 10, or set a smaller width: halving both sides leaves a quarter of the pixels. For photos, below about 60 the blocky look of heavy JPG compression starts to show. The colour profile of the PNG is kept; text notes and other extras stored inside the PNG are not copied.
How to convert PNG to JPG
- Drop the .png file on the box above, or click it and choose the file. One file at a time, up to 50 MB.
- Set the quality. 85 is a good start for photos; use 90 to 95 for a screenshot with small text.
- Optional: type a width, a height or both to make the picture smaller. Leave them empty to keep the original size.
- Press Convert to JPG. The file downloads by itself with your name and a .jpg ending, and the numbers under the button show the size before and after so you can tune it again.
Frequently asked questions
How much smaller will the JPG be?
It depends on the picture. Photos and screenshots with gradients commonly shrink by a large factor; a flat-colour logo may barely shrink, or even grow. The numbers under the button show the original size, the converted size and the percentage left, so you can see the result and convert again with another setting.
What quality should I use for a screenshot with text?
Use 90 to 95. Text has sharp edges, which JPG handles worst, and the default of 85 can leave a faint fringe around small letters. Zoom in on the result to check. If it still looks rough, the picture is a better fit for PNG.
Can I pick the colour that replaces transparency?
No. The replacement is always white. To get another colour, put the picture on a coloured background in an image editor, save it, and convert that file.
Does converting more than once make it worse?
Each time a JPG is converted to JPG again, it is compressed again and loses a little more. Converting a PNG to JPG once is a single round. Going back from JPG to PNG, which you can do with the JPG to PNG page, does not undo the loss; it only stops it from growing.
Is there a limit on the file or the number of conversions?
Files can be up to 50 MB, one at a time. There is no limit on how many times you use the page, no account and no watermark.
Is my picture uploaded?
Yes. The PNG is sent to our server, converted in memory and sent back; the work does not happen in your browser. We keep no copy of the file. For a picture that must not leave your computer, use a program installed on it.
