How to Convert JPG to PNG Online Free
Why convert JPG to PNG?
Converting JPG to PNG might seem counterintuitive since PNG files are usually larger. However, there are several legitimate reasons to convert JPG to PNG:
- Preparing for editing — if you plan to edit a JPG photo and remove the background to add transparency, you need to save it as PNG, which is the next step after editing begins
- Avoiding further compression — if you need to edit and re-save an image multiple times, converting to PNG first prevents additional JPG compression artefacts from accumulating with each save
- Compatibility requirements — some software, printing services, or upload forms specifically require PNG format regardless of the original format
- Lossless archival — converting an important JPG photo to PNG before extensive editing preserves the current quality level without further degradation
Converting JPG to PNG does not improve the quality of the original JPG. Since JPG is already a lossy format, any compression artefacts already present in the JPG will be preserved exactly in the PNG version — converting cannot remove damage that has already occurred.
How to convert JPG to PNG online free — step by step
Our free image converter handles JPG to PNG conversion entirely in your browser. Here is how:
Open the image converter
Go to our free image converter. Works on any device, no installation required.
Upload your JPG files
Drag and drop your JPG images or click to browse. Multiple files can be converted at once.
Select PNG as output format
Click PNG in the format selector. Since PNG uses lossless compression, no quality setting is needed for the conversion itself.
Convert and download
Click Convert and download your PNG files instantly. Note that PNG files will be larger than the original JPG since PNG does not compress as efficiently for photographic content.
When you need JPG to PNG conversion
What happens to quality when converting JPG to PNG?
Converting JPG to PNG is itself a lossless operation — no additional quality is lost during the conversion process. However, it is important to understand that PNG cannot restore quality that was already lost when the original photo was saved as JPG.
In other words, if your JPG has visible compression artefacts from a low quality setting, converting it to PNG will preserve those exact artefacts perfectly — PNG cannot remove or fix damage that already exists in the source image. As a result, converting JPG to PNG "locks in" the current quality level, preventing further degradation from any subsequent edits and saves.
JPG to PNG conversion typically results in a much larger file size with no quality improvement over the original JPG. Only convert to PNG when you specifically need lossless format for editing or transparency — not as a general "quality upgrade" strategy.
Frequently asked questions
Does converting JPG to PNG improve image quality?
No — converting JPG to PNG does not improve quality. It simply preserves the current quality level without further compression. Any quality loss that already exists in the JPG remains exactly the same in the converted PNG file.
Why is my PNG file much larger than the original JPG?
This is expected. PNG uses lossless compression, which produces larger files than JPG's lossy compression — especially for photographic content. A JPG photo converted to PNG can easily be 5–10 times larger in file size while looking identical.
Should I always use PNG instead of JPG?
No — for most photographs and web images, JPG or WebP remain better choices due to much smaller file sizes. Use PNG specifically when you need transparency, lossless quality for ongoing editing, or are working with graphics and text that need sharp, artefact-free edges.
Can I add transparency to a JPG by converting to PNG?
Simply converting a JPG to PNG does not add transparency — the image will still have its original solid background. To add transparency, you need to use an image editing tool to remove or mask the background after converting to PNG, since PNG is the format capable of storing the transparent result.
