How to convert JPEG to PNG?
Select a JPEG image, run the conversion, and download the new PNG file. In Converthy, this operation is performed directly in your browser, without requiring the image to be uploaded to a remote server.
The conversion creates a new file in PNG format. The original JPEG remains on your device and is not modified during the process.
JPEG vs. PNG: what is the difference?
JPEG is widely used for photographs and uses lossy compression to reduce file size. This means that some image information may already have been discarded during a previous JPEG encoding.
PNG uses lossless compression and also supports transparency. Converting a JPEG to PNG does not recover details that were already lost in the original JPEG file, but it creates a new image in PNG format.
When should you convert JPEG to PNG?
The conversion can be useful when a system or workflow requires PNG files or when you want to continue editing and saving the image in a format that uses lossless compression.
The resulting PNG file may be larger than the original JPEG, especially for photographs. For this reason, the conversion should not automatically be considered a way to reduce file size.
Local and private conversion
With this tool, the JPEG image is decoded and converted locally by your browser. The selected file does not need to be uploaded to Converthy servers.
After the conversion, the new PNG file is made available for download directly on your device.
Frequently asked questions
Does converting JPEG to PNG improve image quality?
No. The conversion cannot recover details that were already lost during JPEG compression. It only creates a new representation of the image in PNG format.
Can the generated PNG be larger than the JPEG?
Yes. This is common especially with photographs because PNG and JPEG use different compression strategies.
Is the original JPEG image modified?
No. A new PNG file is created, while the original JPEG remains unchanged on your device.
Is the file uploaded to a server?
Not for this conversion. Processing is performed locally in your browser.
