JPG to PNG Converter

Everything is preset for a JPG in and a PNG out. Add your photos and press one button.

1. Drag one or more JPG or JPEG files onto the box, paste them, or click the box and choose them. The picker accepts both the .jpg and .jpeg endings.
2. Confirm that Convert to reads PNG. The Quality slider does not affect PNG, so it can stay where it is.
3. Press Convert images. Large photos take a few seconds, particularly on a phone.
4. Look at the before and after sizes under each thumbnail. Expect a much bigger file.
5. Download results one by one, or press Download all.

Converting a JPG to PNG does not restore detail that JPEG compression has already removed. Blocky edges and soft shadows stay exactly as they are, and the file almost always grows. So the question is whether you have a reason that is not about quality.

Good reasons include:

• A platform, template or print workflow that only accepts PNG.
• You plan to edit the picture several times and want to save in a lossless format, so each save adds no further JPEG damage.
• You intend to cut out the background in an editor afterwards and need a format that can hold transparency. This converter does not remove backgrounds itself; the PNG it makes is fully opaque.

Poor reasons include hoping the picture will look sharper, or hoping to save space. If the goal is a smaller file, go the other way: PNG to JPG shrinks photos, and the image compressor trims them further.

A small test makes the decision concrete. Convert one photo, then compare its size with the original in the results list. If the PNG is many times heavier and your destination does not insist on PNG, you have your answer. If the destination does insist, the larger file is simply the cost of entry.

It helps to count the pixels. A typical 12 megapixel phone photo measures 4000 by 3000, which is 12,000,000 pixels. With three bytes of color for each pixel, the raw data comes to about 36 MB. The JPG you started with might be around 3.5 MB, because JPEG throws away most of that. PNG compresses without loss and photos rarely shrink below about half of the raw size, so a result somewhere between 15 and 25 MB would not be surprising. That is an estimate for illustration; the tool shows the true size.

Flat graphics behave differently. A JPG of a diagram with large areas of one color may become only a little bigger as PNG.

If your PNG is far larger than the upload limit you are working against, there are two sensible fixes. Reduce the pixel dimensions first with the image resizer, or reconsider the format and use the image converter to choose WebP, which is lighter. Camera data such as location is not copied into the PNG, a side effect of redrawing the picture, so the new file is also cleaner to share. The browser may take a moment and a lot of memory with very large images, so close other heavy tabs if a conversion stalls.

Before you convert, match your situation to the route that actually helps.

Exporting back to JPG at the end brings compression back, so the sensible pattern is to work in PNG and produce a single JPG as the final step. Every extra JPG save costs a little more detail.
