Convert JPG to PNG
PNG is a lossless format, so once an image is a PNG it can be opened, edited and re-saved as many times as you like without losing any more detail. This converter reads your JPGs on your device and writes true 24-bit PNGs. Expect the files to get considerably larger — that is what lossless costs.
How to use the JPG to PNG
- Add your .jpg or .jpeg files by dragging, clicking or pasting.
- Click Convert to PNG. There is nothing to configure: PNG is lossless, so there is no quality slider.
- Check the size summary — PNGs of photographs are normally several times larger than the JPG.
- Download the files one by one, or all together as a ZIP.
PNG cannot undo JPEG
This is the single most important thing to understand about converting in this direction. JPEG compression permanently discards information. When you convert to PNG you get a perfect, lossless copy of the already-damaged pixels: every block artefact, every colour smear and every halo around text is preserved exactly. PNG is a container for what is there, not a repair tool. If someone sends you a heavily compressed JPG, converting it to PNG will not sharpen it.
So why convert at all?
There are four good reasons.
- You are about to edit. Every save of a JPEG re-compresses it, so a file edited five times is noticeably worse than one edited once. Working in PNG between edits stops that generation loss.
- Something requires PNG. Plenty of platforms insist on it: app store icon uploads, some print-on-demand services, many government and banking upload forms, and most design tools that expect an alpha channel.
- You need to add transparency. You cannot cut a background out of a JPEG and keep it cut out — the format has no alpha channel. Convert first, then erase.
- You need exact pixels. Screenshots for documentation, diagrams and anything that will be compared pixel by pixel should be PNG.
What to expect from the file size
| Source | Typical JPG | Typical PNG |
|---|---|---|
| 12 MP phone photo | 3.5 MB | 18–25 MB |
| 1920 × 1080 photograph | 400 KB | 2.5–4 MB |
| 800 × 600 graphic with flat colour | 90 KB | 40–120 KB |
Flat graphics are the exception: PNG can encode large areas of identical colour very cheaply, so a simple logo can come out smaller than the JPG it started as.
Metadata and colour
Because the image is redrawn on a canvas, EXIF data — GPS coordinates, camera model, the date the photo was taken — is not carried into the PNG. Neither is an embedded ICC profile; the output is sRGB, which is what browsers and most software assume. EXIF orientation is applied before saving, so a photo that appeared upright in your browser will be upright in the PNG rather than relying on a rotation flag that some viewers ignore.
Frequently asked questions
Does converting JPG to PNG improve quality?
No. It preserves the current quality perfectly but cannot recover detail JPEG already discarded. Nothing can, short of re-shooting or re-exporting from the original.
Why is the PNG so much bigger?
PNG is lossless. For a photograph there is simply a lot of unique detail to store, so 3–8× the JPG size is normal.
Will the PNG have a transparent background?
No. A JPEG has no transparency, so the PNG is fully opaque. You can erase the background afterwards in an editor, which is exactly why people convert first.
Is EXIF data such as GPS kept?
No. The output PNG contains pixels only. If stripping metadata is your goal, the remove EXIF tool reports exactly what was in the original.
