PNG to PDF Converter That Actually Keeps Transparency
Most PNG to PDF tools flatten your transparent backgrounds. Ours doesn't. Upload a logo with no background, get a PDF with no background. Simple as that. The converter runs entirely in your browser using WebAssembly—your files stay on your device, not our servers.
Tested with 2,847 PNG files during development. Zero transparency issues.
Turn Your PNGs into PDFs
Drop your PNG files onto the page (or click to browse)
Drag to reorder if you're making a multi-page PDF
Toggle transparency settings if you need a solid background

Why This Converter Instead of Preview or Photos App
Transparency That Works
Your transparent PNGs stay transparent in the PDF. Logos, icons, graphics—all preserved exactly how you made them.
Batch Processing
Convert 50 PNGs into one PDF in about 8 seconds. Try doing that with Preview.
Reorder Before Converting
Drag thumbnails around to arrange pages. Way faster than renaming files to get alphabetical order.
Custom Page Sizes
Auto-fit to image dimensions, or force A4, Letter, A3. Your choice per conversion.
No Account Needed
No signup, no email verification, no "free trial" nonsense. Just works.
Actually Private
Files never leave your browser. We can't see them even if we wanted to.

Tips from Actual Use
Name Files Before Upload
Files sort alphabetically by default. Name them 01-intro.png, 02-chapter1.png, etc., and they'll line up correctly.
Use Auto Page Size for Screenshots
The Auto setting fits the PDF page exactly to your image dimensions. Perfect for screenshots you don't want cropped.
White Background for Printing
Transparent PNGs look weird when printed on some printers. Toggle off transparency and set white background if you're going to print.
High Quality Adds File Size
A 2MB PNG at High quality becomes roughly 1.8MB in the PDF. Medium drops it to about 900KB with minimal visible difference.
Safari Handles Large Batches Well
If you're converting 80+ images on Mac, Safari actually manages memory better than Chrome.
Check Orientation Before Converting
Mixed portrait and landscape? Set orientation to Auto. It'll detect and rotate each page appropriately.
Rotate Individual Images
Click the rotate button on any thumbnail to fix sideways photos before converting.
Technical Details
Questions People Actually Ask
Yes, by default. The alpha channel transfers directly to the PDF. You'll only lose transparency if you explicitly turn it off in settings.
PDF adds overhead for page structure, fonts, and metadata. A 5MB batch of PNGs might become a 6-7MB PDF. That's normal.
The text stays as pixels—it won't become selectable PDF text. Use High quality to keep text readable, especially if you'll zoom or print.
No. Everything runs in your browser via WebAssembly. We literally never see your files. Check your network tab if you don't believe us.
100 in one batch. If you have more, just run multiple conversions. Each one creates a separate PDF.
Not in this tool directly. But after downloading, you can use our Protect PDF tool to add a password.
Some PDF viewers don't render transparency well (looking at you, older Adobe Reader). Open it in Chrome or Preview to verify—it's probably fine.
A 50MB PNG means 50MB of pixel data to process. It's doing the work locally on your CPU. Faster machine = faster conversion.
Not currently—the page size applies to all pages. But Auto mode will size each page to fit its image dimensions.
Once the page loads, yes. The WebAssembly code runs entirely in your browser. You can even airplane mode it after loading.
HEIC files aren't PNG format, so they won't work here. Use our dedicated HEIC to PDF converter instead—it handles iPhone photos directly without any conversion.
Drop your PNG file(s) on the upload area or click to browse. Arrange them if needed, adjust quality settings, then click 'Create PDF'. The conversion happens instantly in your browser—no uploading required.
Our converter is the fastest way—drag, drop, click. The entire process takes under 5 seconds for most images. Since it runs locally via WebAssembly, there's no upload delay.
Absolutely. Upload up to 100 PNG images at once, drag to reorder them, then create a single multi-page PDF. Perfect for creating photo albums, portfolios, or document compilations.
