Frequently Asked Questions
Why would I convert a JPG to PNG?
PNG uses lossless compression, so re-saving as PNG prevents any further quality degradation that stacks up every time you re-export a JPG. It also unlocks transparency support — something JPG simply cannot provide — which is essential for layered editing in Photoshop, GIMP, or Figma.
Does converting JPG to PNG improve image quality?
The conversion itself doesn't recover detail already lost when the JPG was originally compressed, but it stops any further quality loss. Every subsequent save of the PNG will stay lossless, making it the better master copy for ongoing editing.
Will the file size get bigger when I convert JPG to PNG?
Yes — PNG is lossless and typically produces larger files than JPG for photographs. That trade-off is worth it when you need pixel-perfect fidelity, plan to edit the image further, or need to preserve fine details that re-saving as JPG would degrade.
Can I add a transparent background after converting JPG to PNG?
Converting to PNG enables the alpha channel, but the existing background remains opaque. You would then open the PNG in an image editor like Photoshop or GIMP to remove or replace that background. The conversion simply unlocks the capability.
Is my photo uploaded to a server when I convert JPG to PNG here?
No. Image Machine runs the entire conversion inside your browser using local processing. Your file never leaves your device, so your photos and designs remain completely private — no account required.
