Understanding PNG Transparency in PDF Conversion
When using any PNG to PDF Converter, one thing always confuses users: transparency. PNG supports transparent backgrounds, but PDF doesn’t handle them the same way.
Meaning?
Your transparent PNG may convert to a white background. That’s expected.
Workarounds:
-
Adobe Online handles transparency gracefully
-
PDFgear flattens layers smoothly
-
Export as PDF directly from Photoshop/GIMP for true transparency
Beware of Hidden “Free” Limits
Not all free converters are really free. Here’s the truth:
| Tool | Free Limit | Hidden Catch |
|---|---|---|
| PDFgear | Unlimited | None |
| iLovePDF | Unlimited | 20-file uploads |
| SmallPDF | 2–3/hour | Login wall |
| FreeConvert | 1GB | Slow w/ adblock |
