What is a JPG to PNG converter?
A JPG to PNG converter changes your image file from the JPEG format to the PNG format. JPG (or JPEG) is the most common photo format on the internet — it keeps file sizes small by compressing the image, but that compression permanently removes some detail. PNG, on the other hand, is a lossless format: it preserves every pixel exactly, and it supports transparency, which JPG cannot do.
People convert JPG to PNG when they need the highest possible quality for editing, when they want to avoid further quality loss from repeated JPG saves, or when preparing images for design work where transparency or crisp edges matter.

Frequently asked questions
Will converting JPG to PNG improve image quality?
No — conversion cannot add detail that JPG compression already removed. But PNG prevents any further quality loss, which is why it's ideal for editing and archiving.
Why is the PNG file bigger than the JPG?
PNG uses lossless compression, so it stores more data than JPG. Larger file size is normal and expected — it's the price of perfect quality.
Is it safe to convert personal photos here?
Yes. Your photo never leaves your device — the conversion runs entirely in your browser, so there is zero risk of your images being stored or seen by anyone.
Can I convert multiple JPG files at once?
Currently the tool converts one image at a time for maximum speed and reliability. Batch conversion is planned for a future update.
Does converting JPG to PNG add transparency?
No. JPG never contains transparency, so there is nothing to keep — the converted PNG shows the image exactly as it looked, with a flat background. If you need true transparency, you would have to remove the background with an editor first.
Should I use PNG or JPG for my website?
It depends on the image. Use PNG for logos, icons, screenshots and graphics with sharp edges or text — PNG keeps them crisp. Use JPG for photos, which are much smaller and load faster. For the smallest possible photos, try our image compressor.
Will the PNG work everywhere?
Yes. PNG is supported by every browser, phone, computer and printer made in the last 20+ years. It is a safe, universal format for sharing and printing.
