Open Convert Image →2. The transparency catch — and the fix
This trips people up: JPG has no transparency. If you convert a PNG with a see-through background straight to JPG, those transparent pixels have to become something — and a naive converter often turns them black. The fix is to fill transparent areas with a chosen background colour (white is usual) before encoding. PDFNest does this automatically and lets you pick the colour, so logos and graphics come out on a clean white background instead of an ugly black one.
3. PNG or JPG: which should you use?
| Use JPG for… | Use PNG for… |
|---|---|
| Photographs | Logos & icons |
| Small file size | Transparency |
| Email & uploads | Sharp text & line art |
4. Converting the other way (JPG to PNG)
Going from JPG to PNG won't add quality back — JPG already discarded detail — but it's useful when you need a lossless copy to edit, or a format that supports transparency you'll add later. Same tool: drop in the JPG and choose PNG as the output.
5. Batch converting
Got a folder of PNGs? Add them all, pick JPG once, and convert the whole set in one go — then grab them individually or as a single ZIP. To make the files smaller as well as change format, follow up with Compress Image, or read our image compression guide.
