About PNG to JPG

Convert PNG to JPG when an image is too heavy to email or an upload form only takes JPG. PNG stores every pixel without loss, which is ideal for editing but makes photos and large screenshots bulky. JPG drops detail your eye barely notices and gives you a far lighter file. For forms that only take JPG, iPhone photos in HEIC format can be converted with HEIC to JPG.

JPG can't store transparency, so transparent areas are filled with the Background color you pick, white by default, and soft edges blend into it smoothly. The Quality slider starts at 90; from 90 up, color detail is saved at full resolution, which keeps red text and thin colored lines crisp. Resize sits under More options, and Keep photo info (EXIF) decides if camera details stay in the file.

How to use PNG to JPG

  1. 1
    Upload your PNG

    Click Choose file or drop the PNG on the page. Free accounts can convert files up to 50 MB, VIP up to 1 GB.

  2. 2
    Set quality and background

    Move the Quality slider, pick a Background color for transparent areas and open More options if you want to resize.

  3. 3
    Click PNG to JPG

    The image is converted on our server in its own isolated process.

  4. 4
    Download the JPG

    Save the file. It keeps the original name with a .jpg ending, so logo.png becomes logo.jpg.

Why use Cubfile for this

  • Background color you choose

    Transparent areas become white, black or any color you pick, and semi-transparent edges blend into it instead of turning jagged.

  • Quality from 10 to 100

    90 is the default. At 90 and above, color detail keeps its full resolution; lower values make the file smaller still.

  • Resize in the same step

    Keep the size, set a width or height, fit the picture in a box, or scale it by percentage.

  • Photo info on or off

    Keep photo info (EXIF) is on by default. Switch it off to leave out camera details, date and location.

FAQ

PNG to JPG: questions and answers

Will PNG to JPG make my image lose quality?
A little, because JPG is a lossy format, but at the default quality of 90 the difference is hard to spot in photos. Screenshots with small text show JPG artifacts sooner, so keep the quality high for those.
What happens to transparent areas when I convert PNG to JPG?
They're filled with the Background color, white unless you choose another one. JPG can't hold transparency at all, so if you need a see-through logo, keep the PNG. A logo that has to scale cleanly can also be traced into a vector with PNG to SVG.
How many PNG files can I convert for free?
Without an account you get 2 conversions in total; a free account gives you 2 a day for files up to 50 MB. VIP has no daily limit, takes files up to 1 GB and converts up to 50 images per task.
Can I make the JPG smaller in pixels too?
Yes. Open More options, choose Resize and pick Set width, Set height, Fit in a box or By percentage. Fit in a box shrinks the image to fit the width and height you enter and never stretches it.
Are my images stored after conversion?
Only for an hour. The upload travels over HTTPS, each job runs in its own isolated process, and the PNG and the JPG are deleted automatically when the hour is up. We never look at them or use them to train AI.
