How to convert JPG to PNG
Drag a JPG into the box — it opens locally and is never uploaded. Other formats like WebP or BMP are accepted too and convert the same way.
Click Convert & Download. The page re-encodes the image pixel by pixel into PNG — a lossless format that keeps every detail exactly as it is in your JPG.
Check the size readout before saving: it shows your source size next to the PNG size. A larger PNG is normal and expected — the page tells you the real numbers, not a made-up smaller one.
Know-how
JPG and PNG explained in plain terms
Both formats show the same picture, but they store it differently. JPG was designed for photographs: it saves space by recording each pixel approximately, discarding details the eye barely notices. PNG was designed for fidelity: every pixel is stored exactly. Think of JPG as a summary of the picture and PNG as the picture itself — the summary is much smaller, the original is exact.
Why the PNG gets bigger — and why that is fine
A bigger file here is not a defect; it is the price of precision. JPG compresses by guessing, PNG by describing. When you convert, nothing about your image changed — the same pixels are simply being written down more completely. The only situations where a JPG-to-PNG conversion stays small are flat graphics and screenshots with large uniform areas, which PNG compresses very well.
PNG cannot bring back lost detail
This is the most common misconception about format conversion. A conversion only changes the container — not the pixel data. If a JPG was saved at low quality years ago, the blur and blocky artifacts are already baked into the pixels. Converting to PNG makes those pixels permanent, which is why the best time to use PNG is before quality is lost: when exporting graphics, screenshots, or your own edits.
Where each format belongs
A practical rule of thumb: photographs travel as JPG, everything crisp travels as PNG. Social posts, emails, and websites load faster with JPG photos. Logos, product icons, diagrams, and anything you will edit again deserve PNG. Screenshots sit between: capture them, and if they contain text you will read or share, PNG keeps the text razor-sharp.
Common mistakes to avoid
Converting back and forth between JPG and PNG repeatedly is the classic trap: each round trip through JPG shaves off a little more quality. Uploading huge PNG photos to a website is another — a PNG photo that loads in four seconds would load in half a second as a high-quality JPG. And assuming PNG means higher quality is the third: the format never adds quality, it only preserves what exists.
Frequently asked questions
Is the JPG to PNG converter free?+
Yes. Conversion runs entirely in your browser — there is no server, no upload, and no limit on how many files you convert.
Why is my PNG bigger than the JPG?+
That is expected. JPG is a lossy format — it aggressively approximates pixels to shrink the file. PNG is lossless: it stores every pixel faithfully, so a photo converted from JPG typically ends up two to ten times larger. The trade-off is that PNG never adds further compression artifacts when you edit and re-save it.
Will converting JPG to PNG improve the quality?+
No. PNG stores faithfully what is already in the JPG, but it cannot restore detail that JPG compression already discarded. What it does prevent is future loss: every time a JPG is edited and re-saved, it degrades a little more, while PNG re-saves stay identical.
When should I use PNG instead of JPG?+
Use PNG for anything with sharp edges that JPG would smear: screenshots, logos, charts, and text-heavy images. Use it as a working format when you will edit the image several more times. For finished photographs going to the web or chat, JPG at high quality is almost always the better choice because of its much smaller size.
Does PNG support transparency?+
Yes, PNG fully supports transparency — but a JPG source has none to preserve, so converting one will never create a transparent background. If you need a transparent PNG, remove the background first with the Background Remover tool, then save as PNG.
