About JPG to PNG

JPG to PNG is the step to take before editing. Every time a JPG is saved it gets compressed again, and small blocky artifacts build up around edges and text. A PNG copy is lossless, so you can crop, annotate and re-save it in any editor without that creeping loss. Design tools and upload forms that ask for PNG accept it right away. HEIC photos from an iPhone can go straight to lossless PNG with HEIC to PNG.

Converting can't bring back detail the JPG already threw away, and the PNG will usually be larger than the original. Keep photo info (EXIF) is on by default, so camera and date details come along, and the DPI value stored in the JPG carries over too. Under More options you can resize the picture while it converts.

How to use JPG to PNG

  1. 1
    Choose your JPG

    Click Choose file or drop a .jpg or .jpeg file on the page. It uploads over HTTPS.

  2. 2
    Decide on photo info

    Leave Keep photo info (EXIF) on to carry camera details over, or turn it off. Resize options sit under More options.

  3. 3
    Click JPG to PNG

    Our server decodes the JPG and writes a lossless PNG in an isolated process.

  4. 4
    Save the PNG

    Download the file, which keeps its original name, so photo.jpg becomes photo.png.

Why use Cubfile for this

  • Lossless from here on

    Edits and re-saves no longer add compression artifacts, which matters for images you'll keep working on.

  • Camera details kept

    Camera model, date taken and location stay in the PNG unless you switch them off.

  • Resize on the way

    Set a width or a height, fit the image in a box or scale it by percentage during the conversion.

  • Same DPI

    The resolution value stored in the JPG goes into the PNG, so print dimensions don't change.

FAQ

JPG to PNG: questions and answers

Does converting JPG to PNG improve quality?
No. The PNG is an exact copy of the pixels in your JPG, artifacts included. What it prevents is further loss, because saving a PNG doesn't compress it again.
Why is my PNG so much bigger than the JPG?
PNG stores every pixel with lossless compression, while JPG discards detail to save space. For photos, a larger PNG is normal; for simple graphics the gap is smaller. When you're done editing, PNG to JPG turns it back into a lighter file for sharing.
Will JPG to PNG give me a transparent background?
No, the background stays exactly as it was, white or otherwise. PNG can hold transparency, but converting doesn't remove anything from the picture.
How many JPG files can I convert without paying?
Visitors get 2 conversions in total and free accounts 2 per day, each file up to 50 MB. With VIP there's no daily cap, files can be up to 1 GB, and a single task converts up to 50 images.
Who can see the photos I upload?
No one on our side. Photos travel over an encrypted connection, are converted in an isolated process and are erased automatically after one hour. We don't share or sell them, and they're never used for AI training.
