There are good reasons to convert JPG to PNG — a design app that only accepts PNG, a document you’ll keep editing, or an upload form that refuses JPEGs. There are also a couple of popular myths, like the idea that converting will magically sharpen a photo or remove its background.
This guide sorts fact from fiction, then shows the quickest way to convert on every device.
What Is the Difference Between JPG and PNG?
JPG (also written JPEG) uses lossy compression: it discards detail the eye barely notices to keep photos small. PNG uses lossless compression: every pixel is stored exactly, and it supports transparency.
| JPG | PNG | |
|---|---|---|
| Compression | Lossy | Lossless |
| Transparency | No | Yes |
| Re-saving | Loses a little quality each time | No loss, ever |
| File size for photos | Small | Large (often 3–10×) |
| Best for | Photos | Graphics, text, editing, logos |
How to Convert JPG to PNG Online (Step by Step)
Using our free JPG to PNG converter:
- Open the tool in your browser.
- Upload a JPG or JPEG file.
- Click Convert.
- Download the PNG.
The image keeps its exact dimensions and looks identical to the original. No sign-up, no watermark.
Does Converting JPG to PNG Improve Quality?
No — and this is the most common misunderstanding. Whatever detail the JPG lost when it was first saved is gone for good. Converting to PNG preserves the image exactly as it is now, compression artefacts included.
What PNG does give you is protection from further loss. If you’ll edit an image several times — adding text, cropping, adjusting colours — saving each version as PNG avoids the gradual degradation you get from re-saving JPGs.
Will JPG to PNG Make the Background Transparent?
Not on its own. A JPG has no transparency information, so the converted PNG has the same solid background as before — it’s just stored in a format that could hold transparency. To get a transparent background you need to remove the background as a separate step in an editor, then save as PNG.
This is worth knowing before you convert a logo expecting a see-through result. If you have the original logo file from a designer, ask for the PNG or SVG version instead.
Why Convert JPG to PNG?
- A website, app or print template accepts PNG only.
- You’ll be editing the image repeatedly.
- The image contains text or sharp lines that you’ll overlay on other graphics.
- You want to add transparency later in a design tool.
If none of these apply — for example you just want to share a photo — keep it as JPG. The PNG will be much larger with no visible benefit.
Convert JPG to PNG on Windows
Open the JPG in Paint, choose File → Save as → PNG picture. That’s it. The online converter gives the same result and works on any computer without installing anything.
Convert JPG to PNG on Mac
Open the image in Preview, choose File → Export and pick PNG as the format. To convert several images, select them all in the Preview sidebar first.
Convert JPG to PNG on iPhone and Android
Neither phone offers a simple format switch for photos. Open the converter in Safari or Chrome, upload from your gallery and save the PNG. This is the easiest method if you need a PNG for an app or form on the go.
Why Is the PNG So Much Larger?
A 1 MB JPG photo can easily become a 6 MB PNG. That’s normal: lossless storage of a detailed photo takes a lot of data. If the size is a problem, compress it with Compress PNG or reconsider whether PNG is really needed. For websites, JPG to WebP is usually a better upgrade — it’s smaller than JPG and supports transparency.
Converting Many JPGs at Once
For a whole folder, Batch Image Converter converts everything to PNG in one go and returns a ZIP.
Going the Other Way
If you have a PNG photo that’s too big to upload, PNG to JPG shrinks it dramatically. And if you’re not sure what format a file really is — some “.jpg” downloads are actually WebP — Image Format Detector will tell you.
Is It Safe to Use a JPG to PNG Converter?
Yes, provided it doesn’t keep your photos. Ours converts in memory and deletes each image straight away. No account is needed. For background, the PNG format was created as an open, patent-free alternative to GIF, which is why it’s supported everywhere.
Final Thoughts
Converting JPG to PNG won’t restore lost detail or remove a background, but it does give you a lossless file that’s safe to edit and accepted by PNG-only apps. Use it when you have a reason, and keep photos as JPG when you don’t. Try the free JPG to PNG converter whenever you need one.
