- Use the PNG. Use the PNG wherever you need the image in PNG format, benefiting from PNG's characteristics.
What JPG and PNG Are
JPG and PNG are both common image formats with different characteristics. JPG uses lossy compression, keeping files small, and does not support transparency, making it good for photos where small size matters. PNG uses no lossy compression, preserving quality, and supports transparency, making it good for graphics, images needing transparency, or where quality matters. Converting JPG to PNG changes a JPG into the PNG format.
The reason to convert JPG to PNG is when you need the image in PNG format, for its characteristics. You might want PNG because it supports transparency, which JPG does not, or because you want the image in a format that does not use lossy compression going forward. So converting a JPG to PNG gives you the image in PNG format, with PNG's support for transparency and lossless nature.
JPG and PNG differ in compression and transparency. JPG is compact via lossy compression but has no transparency, suited to photos. PNG is larger, lossless, and supports transparency, suited to graphics and images needing transparency or quality. Note that converting a JPG, already compressed with loss, to PNG does not restore quality lost in the JPG, but gives PNG format going forward. So the conversion provides PNG's format and features.
JPG to PNG conversion is used when someone needs a JPG image in PNG format: to have it in a format supporting transparency, to use PNG where required, or to work with the image in PNG going forward. Because JPG and PNG suit different needs, and PNG offers transparency and lossless handling, converting a JPG to PNG is a practical task when the PNG format is what you need.

Frequently Asked Questions
How do I convert JPG to PNG?
Provide the JPG image you want to convert, and the tool converts the JPG into a PNG image, changing the format to PNG. Receive the PNG image, your picture now in PNG format, which supports transparency and uses no lossy compression, review it to confirm it converted correctly and appears as expected, then use the PNG wherever you need the image in PNG format. This gives you the image in PNG, benefiting from PNG's support for transparency and lossless nature, useful when you need the image in PNG format, such as for transparency support or a use requiring PNG. Note that converting a JPG, already compressed with loss, to PNG does not restore quality the JPG already lost, but provides the PNG format going forward. So you get the image as a PNG with PNG's features, at the quality of the source JPG.
What are JPG and PNG?
JPG and PNG are both common image formats with different characteristics. JPG uses lossy compression, which keeps files small by discarding some detail, and does not support transparency, making it good for photos where small file size matters. PNG uses no lossy compression, preserving quality without discarding detail, and supports transparency, making it good for graphics, images needing transparency, or where quality matters, though its files are larger. So JPG is compact but lossy with no transparency, while PNG is larger but lossless with transparency support. Converting JPG to PNG changes a JPG image into the PNG format, giving it PNG's characteristics: transparency support and no further lossy compression. So the two formats suit different needs, and converting between them lets you have an image in whichever format your use requires, with this converter turning a JPG into a PNG when you need the PNG format and its features.
What is the difference between JPG and PNG?
JPG and PNG differ mainly in compression and transparency. JPG uses lossy compression, discarding some detail to achieve small file sizes, and does not support transparency, which suits photos where compact size is valued. PNG uses lossless compression, preserving all detail without loss, and supports transparency, which suits graphics, logos, images needing transparent areas, or where quality matters, though PNG files are larger than JPG. So JPG offers small files at the cost of some quality and no transparency, while PNG offers full quality and transparency at the cost of larger files. This means you choose JPG for compact photos and PNG for graphics, transparency, or quality. Converting JPG to PNG gives the image PNG's lossless format and transparency support, useful when you need those, though it cannot restore detail the JPG already lost. So the key differences are JPG's lossy compact nature versus PNG's lossless, transparency supporting, larger format, each suited to different uses.
Will converting to PNG improve the quality?
No, converting a JPG to PNG will not improve the quality beyond that of the original JPG, because the JPG has already lost some detail to its lossy compression, and converting to PNG cannot restore that lost detail. The PNG will be at the quality of the source JPG, not better. What converting to PNG does provide is the image in a lossless format going forward, meaning no further lossy compression is applied, and PNG's support for transparency. So the benefit is the PNG format and its features, not restored quality. It is a common misunderstanding to expect converting to a lossless format like PNG to recover quality lost by a lossy format like JPG, but the lost detail cannot be recovered by conversion. So convert JPG to PNG when you need PNG's format or features, such as transparency or lossless handling from that point on, understanding that the image quality will match the source JPG rather than improve, since the earlier loss from JPG compression is permanent and not reversible by converting to PNG.
Why convert JPG to PNG?
You convert JPG to PNG when you need the image in PNG format for its characteristics. The main reasons are that PNG supports transparency, which JPG does not, so if you need the image to have transparency, converting to PNG provides a format that supports it; that PNG uses no lossy compression, so you want the image in a lossless format going forward; or that a particular use requires the PNG format specifically. So converting a JPG to PNG gives you the image in PNG, with PNG's transparency support and lossless nature. This is useful for graphics work where PNG is often preferred, for images needing transparency, or wherever PNG is required. So you convert JPG to PNG to meet a need for the PNG format or its features, rather than for a quality improvement, since the conversion provides PNG's format and capabilities but keeps the image at the quality of the source JPG. So the conversion is about getting the appropriate format for your use, particularly when transparency or a lossless format is needed.
Should I keep the original JPG?
Yes, you should keep your original JPG if you may still need it, such as for its smaller file size, so you retain both the compact JPG and the PNG version for their respective uses. JPG's lossy compression makes it smaller, which is useful for sharing or where file size matters, while the PNG you converted to is larger but lossless and supports transparency. So keeping both lets you use the JPG where compact size is preferred and the PNG where you need transparency or the PNG format. If you convert to PNG and discard the JPG, you lose the smaller version, which you might want for sharing or storage. So retaining the original JPG alongside the PNG gives you both formats, letting you use whichever suits each purpose. So it is sensible to keep the JPG if there is any chance you will need the compact version, using the PNG for its features and the JPG for its smaller size, rather than losing the original JPG by discarding it after converting.
Is the JPG to PNG converter free?
Yes, it is completely free with no account and no usage limit. You can convert as many JPG images to PNG as you like, as often as you like, at no cost. It runs in your browser on any device, so there is nothing to download or install, and your PNG image is ready once the JPG is converted. Use it to turn JPG images into PNG format when you need PNG's characteristics, such as its support for transparency, which JPG lacks, or a lossless format going forward, or when a use requires PNG. Remember that converting cannot restore quality the source JPG already lost to its lossy compression; the PNG matches the JPG's quality while providing PNG's format and features. Check the converted PNG looks correct, and keep your original JPG if you may still need its smaller size for sharing or storage.
