JPG is the go-to format for photos because the files are small — but that compression comes at a cost. When you need crisp edges, a format you can edit without quality loss, or a transparent background, it is time to convert your JPG to PNG. This guide shows you exactly how to do it for free, online, and without uploading your file anywhere — and how to knock out a white background while you are at it.
If you just want to convert now, open our free JPG to PNG converter — no signup, no watermark, nothing to install. Otherwise, here is everything worth knowing.
JPG vs PNG: what is the difference?
The two formats solve different problems:
- JPG (JPEG) uses lossy compression. It is excellent for photographs because it makes files tiny, but it can blur fine text and leave artefacts around sharp edges. It does not support transparency.
- PNG is lossless, so it keeps every pixel exactly. It is the better choice for logos, screenshots, diagrams and anything with crisp lines or text — and it supports transparency.
So you convert JPG to PNG when quality and clean edges matter more than the smallest possible file size, or when you need a transparent background that JPG simply cannot provide.
How to convert JPG to PNG (step by step)
- Open the JPG to PNG tool.
- Drag your JPG files onto the box, or tap to pick them from your device. You can add several at once.
- Leave the background option on “Keep as-is” for a faithful copy.
- Click Convert to PNG.
- Download each PNG, or grab them all in a single ZIP.
The whole thing happens in your browser, so there is no upload or download wait — conversion is instant and your images stay on your own machine.
How to make a JPG background transparent
This is the feature most people are really looking for. Because JPG cannot store transparency, the only way to get a see-through background is to convert to PNG and remove the background during that step. Here is how:
- Add your image — ideally a logo, signature or icon on a plain white background.
- Set the background option to “Make white background transparent”.
- Adjust the tolerance slider: a higher value removes more off-white and light-grey pixels.
- Convert and download your PNG with a transparent background.
This approach works brilliantly for clean white backgrounds. If your image has a busy or multi-coloured background, automatic removal will not be precise — for those, a dedicated background-removal tool that detects the subject is a better fit.
Why convert JPG to PNG?
Common reasons people make the switch:
- Transparency: place a logo over any colour or photo without a white box behind it.
- Crisp text and lines: PNG avoids the fuzzy edges JPG can introduce.
- Editing: PNG does not lose quality each time you save, unlike JPG.
- Graphics and screenshots: PNG is the standard for UI, icons and diagrams.
Is it safe to convert JPG to PNG online?
Many converters upload your image to a server, which is a privacy risk for anything personal or confidential. The BSM Sites converter runs entirely in your browser — your files are never uploaded, stored, or seen by anyone. That makes it safe for ID photos, signatures, client work and private images.
Converting JPG to PNG on your phone
The tool is fully mobile-friendly. On Android or iPhone, open it in Chrome or Safari, choose JPG images from your gallery, convert, and save the PNGs straight to your device or share them from the browser.
Common questions and quick fixes
My PNG file is bigger than the JPG. That is normal — PNG is lossless, so it stores more data. If size matters more than quality, you may actually want the reverse: PNG to JPG.
The transparent areas still show some white edges. Increase the tolerance slightly, or make sure the original background is a clean, even white.
Part of my subject went transparent too. Your subject contains near-white pixels. Lower the tolerance so only true white is removed.

Frequently asked questions
How do I convert a JPG to PNG without losing quality?
Use a converter that exports PNG, which is a lossless format. The conversion adds no new quality loss. Note that compression already in the original JPG cannot be undone, but the PNG will preserve the image exactly as it currently looks.
Can I make a JPG background transparent?
JPG cannot store transparency, but PNG can. Convert the JPG to PNG with a tool that offers a make-white-transparent option, which clears plain white areas. It works best on logos, signatures and icons on a clean white background.
Is it safe to convert JPG to PNG online?
It is safe when the tool runs in your browser instead of uploading files. The BSM Sites JPG to PNG converter processes images locally on your device, so nothing is sent to a server.
