JPG to PNG Converter
Converting JPG to PNG gives you a lossless copy that survives editing without degrading further, and a file accepted by tools that insist on PNG. Nothing is added to the image, nothing is invented, and no detail already lost to JPEG compression comes back. The conversion happens locally in your browser in a fraction of a second.
How to convert JPG to PNG
- Drop your JPG files into the box above, click to browse, or paste an image with Ctrl+V.
- Adjust the quality, background or output size if you need to. The defaults are already sensible.
- Click Convert and download your PNG files, one by one or as a single ZIP archive.
Why convert JPG to PNG
The strongest reason is generational loss. Every time a JPEG is opened, edited and saved again it is recompressed, and the damage accumulates until edges blur and flat areas turn blotchy. Converting to PNG once, then editing in PNG, stops that cycle because PNG stores pixels exactly. The second reason is a requirement rather than a preference: design tools, game engines, app icon pipelines, presentation templates and plenty of upload forms accept PNG and nothing else. A third is that PNG has an alpha channel, so once the photograph is a PNG you can cut out a background and keep it transparent, which JPEG can never do.
Your files stay on your device
Conversion happens entirely inside your browser using standard web technologies. Nothing is uploaded, nothing is stored, nothing is logged. You can open your browser network inspector during a conversion and watch it stay completely silent.
About JPEG Image
JPEG, almost always seen with the .jpg extension, has been the standard format for photographs since 1992. It compresses by discarding the detail the human eye is least likely to notice, which makes photographic files dramatically smaller at a quality setting most people cannot distinguish from the original. Practically every device, application, printer and web form accepts JPEG without question, which is why it remains the safest format to hand to someone else. It has two firm limits: no transparency at all, so transparent areas must be flattened onto a solid colour, and lossy compression, so every re-save of an edited JPEG throws away a little more detail.
- Released by the Joint Photographic Experts Group in 1992 and still the most widely supported image format in existence.
- Quality is adjustable from 1 to 100; above roughly 85 the visual gain is hard to see while the file keeps growing.
- No transparency support whatsoever, which is why transparent images need a background colour first.
- Generational loss is real: opening, editing and re-saving the same JPEG repeatedly degrades it visibly.
- The safest choice for email attachments, print submission and any upload form with a strict format list.
About PNG Image
PNG, short for Portable Network Graphics, was published in 1996 as a patent-free replacement for GIF and has been the default lossless image format of the web ever since. It stores pixels exactly as they were written, so text stays sharp, flat colour stays flat, and repeated editing never degrades the image. Its alpha channel carries 256 levels of transparency, which makes it the standard choice for logos, icons, screenshots and interface assets. The cost is file size: because nothing is discarded, a photograph saved as PNG is routinely four to ten times larger than the same photograph saved as JPEG or WebP.
- Standardised by the W3C in 1996 and supported by every operating system, browser and image editor.
- Lossless: re-saving a PNG a hundred times produces a pixel-identical file every time.
- True 8-bit alpha channel, so edges and soft shadows blend cleanly onto any background.
- Ideal for screenshots, logos, line art and anything containing text; a poor choice for photographs.
- Cannot store animation. APNG exists but is a separate extension with uneven support.
Frequently asked questions
Does converting to PNG restore the quality my JPEG lost?
No. JPEG compression is permanent, and any artefacts in the original are copied into the PNG exactly as they are. What PNG gives you is a guarantee that no further quality is lost from this point on.
Why is my PNG so much bigger than the JPEG?
Because it is lossless. A photograph as PNG is commonly 5 to 10 times the size of the JPEG it came from. That is the expected cost of storing every pixel rather than an approximation of them.
Will my JPEG photo have a transparent background after converting?
No. The PNG gains the ability to store transparency, but the photograph itself is fully opaque. Removing a background is a separate editing step that this tool does not perform.
When is this conversion actually worth doing?
When you are about to edit the image repeatedly, when a tool or platform demands PNG, or when you need a base file to cut a transparent background out of. For simply storing or sending a photograph, the JPEG is the better file.
What happens to the EXIF data and GPS location in my photo?
It is removed. The image is redrawn from decoded pixels, so camera model, timestamps and location coordinates are not carried into the PNG. That is usually a benefit when the image is going to be shared.
