Add files from where they live
Drop a JPG file on the box, browse for it, or import it from Dropbox, Google Drive or a link. You can add more files later, and each file gets its own result.
Free JPG to PNG converter
Convert JPG to PNG online. Add a file, confirm PNG and download it. A single file needs no account.
Converting JPG to PNG rewraps your image in a lossless container. Nothing already lost to JPEG compression comes back, the artefacts baked into the JPG are copied across exactly, but no further detail is discarded, so the PNG is safe to edit and re-save repeatedly without degrading.
Transfers use HTTPS, and files converted on the free tier are deleted within 24 hours, so the result is not a long-term archive. Quality depends on the source file, so open the PNG file once before you share it.
FromJPGLossy
JPEG (Joint Photographic Experts Group)
A lossy raster format tuned for photographs. It discards fine detail to reach small file sizes, and it has no alpha channel, so a JPG can never carry a transparent background.
ToPNGLosslessTransparency
PNG (Portable Network Graphics)
A lossless raster format with a full alpha channel. It preserves every pixel it is given and supports transparency, which makes it the usual choice for logos, screenshots, and any image with sharp edges or text.
Why use indox to convert JPG to PNG?
Watch the job run
A progress bar shows the file moving through the conversion. If you picked the wrong file, cancel and start again.
Download it or hand it on
Save the PNG file, copy a share link or convert it to another format. Free-tier output expires on its own after 24 hours.
What changes
- Compression switches from lossy to lossless: the PNG stops shedding quality on every save, which matters if the file will be edited more than once.
- An alpha channel becomes available, so you can erase a background after converting, though the JPG itself arrives fully opaque and nothing is made transparent automatically.
- File size usually grows, often two to five times, because PNG stores exact pixel data instead of approximating it.
- JPEG blocking and ringing artefacts already in the source are preserved verbatim; PNG records them faithfully rather than cleaning them up.
How do I convert JPG to PNG online?

What do I get from indox's JPG to PNG converter?
You upload a JPG file, indox converts it to PNG, and you download the result. A single file needs no account, and nothing is installed.
- No install and no account for a single file
- PNG output you can download or share
- Progress while the job runs, with a cancel button
- Free-tier files are deleted within 24 hours
What are the limits for JPG to PNG?
Size
The upload box shows the live size limit before you add a file. Signing in raises it, and paid plans raise it further.
Formats
JPG in, PNG out. Pick another output on the converter if you need a different format.
Privacy
Files are encrypted in transit over HTTPS and processed on indox infrastructure.
Deletion
Free-tier files are deleted automatically within 24 hours after the job finishes.
Limits worth knowing
- This is not a quality repair. Detail destroyed by the original JPEG compression cannot be recovered by changing container.
- The result is opaque. Transparency becomes possible after conversion but is not applied for you.
- For photographs intended only for display, the larger PNG brings no visible benefit over the JPG.

Which conversions are close to JPG to PNG?
Who can use a JPG to PNG converter?
When to use it
- Preparing a photo for editing where it will be saved several times and further JPEG loss is unacceptable.
- Getting an image into a format that accepts transparency before cutting out a background.
- Meeting an upload requirement that accepts PNG only, such as some print services and app-store assets.
- Archiving a screenshot or a graphic containing text, where PNG keeps edges crisp instead of smearing them.

JPG to PNG FAQs
Is JPG to PNG lossless?
The conversion step itself is lossless, every pixel in the JPG is copied into the PNG unchanged. What is not lossless is the history: the original JPEG compression already discarded detail permanently, and converting cannot bring it back. So you get a lossless copy of an already-lossy image.
Will converting JPG to PNG give me a transparent background?
No. JPG has no alpha channel, so every pixel arrives opaque and the PNG is a solid rectangle. Converting gives you a format that supports transparency, which lets you remove the background afterwards in an editor. Nothing is cut out during conversion.
Why is my PNG larger than the JPG?
PNG stores exact pixel values with lossless compression, while JPEG approximates them and throws away what the eye is least likely to miss. For a photograph the PNG is commonly two to five times bigger. For flat graphics, logos, or screenshots the gap narrows and PNG can even come out smaller.
Is PNG better quality than JPG?
PNG preserves what it is given, so it is the better choice when an image will be edited repeatedly or needs transparency or crisp text. It does not improve an existing JPG. For a photo displayed once, a good-quality JPG looks the same at a fraction of the size.
Can I just rename a .jpg file to .png?
No. The extension does not change the bytes inside, so the file is still JPEG data wearing the wrong name. Some software will detect this and open it anyway, but strict tools will reject it as corrupt. A real conversion re-encodes the image data.
