You can convert PNG to PDF for free without uploading your images to a server. Inkfolio builds the PDF entirely on your own device, so your files never leave your browser.
Why PNG specifically needs its own conversion
PNG is the default format for screenshots, exported graphics, and images with transparency — different from JPG, which is more common for photos. Because PNG files behave a little differently (especially around transparency), converting them to PDF cleanly matters if you’re turning screenshots, diagrams, or design exports into a shareable document.
Step-by-step: converting PNG to PDF
- Go to Inkfolio’s PNG to PDF tool
- Upload one or more PNG images
- Reorder them if you’re combining multiple images
- Click “Convert to PDF”
- Download your PDF file
What happens to transparent backgrounds
PDFs don’t support transparency the way PNGs do, so any transparent areas in your PNG will typically display as white once placed on a PDF page. This is worth knowing in advance if your PNG has a transparent background you were relying on — the PDF version will show a solid white background in its place instead.
What it’s good for
- Turning a batch of screenshots into a single shareable document
- Converting design exports or diagrams into a printable PDF
- Combining multiple PNG images (like scanned pages saved as PNG) into one file
- Creating a PDF from images for portals that only accept PDF uploads
A quick honest note on quality
The PDF preserves your PNG at its original resolution — conversion doesn’t compress or degrade the image. If your PNG was already low-resolution (a small screenshot, for example), the resulting PDF page will show the same limitations, since converting only changes the file format, not the image’s actual detail.
Combining screenshots into a document
A common use case is turning a series of screenshots — like steps in a tutorial, or a record of an error message across several screens — into one shareable file instead of several loose images. Uploading them in order and combining them into a single PDF keeps the sequence intact and makes the whole thing easy to send or archive as one document, rather than managing individual image files.
Getting the page order right
Like any multi-image conversion, the order you arrange your PNGs in before converting becomes the page order in the resulting PDF. If you’re compiling screenshots taken over time, it helps to check filenames or timestamps and sort them into the right sequence before uploading, rather than reordering manually inside the tool afterward.
PNG vs. JPG: when it actually matters which one you use
For most everyday screenshots, either format works fine once converted. The difference matters more for images with sharp edges and text (like a screenshot of a spreadsheet or code) — PNG tends to render these more cleanly since it uses lossless compression, while JPG’s compression can slightly blur fine details. If your screenshots were originally saved as PNG, converting them directly (rather than converting to JPG first) keeps that sharpness intact.
Large batches of PNG files
If you’re converting many PNGs at once — a folder of dozens of screenshots, for example — the process works the same way as converting just a few, though it may take a little longer to process the full batch. There’s no need to convert them in smaller groups; uploading the complete set and letting the tool handle ordering and combining in one pass is simpler than managing multiple partial conversions.
Do you need internet access for this to work
Only to load the page itself the first time. Once Inkfolio’s PNG to PDF tool has loaded in your browser, the actual conversion — reading your images and building the PDF — happens locally using your device’s own processing power, not a server somewhere else. This is also why nothing about your images gets uploaded during the process: there’s no server-side step for your files to pass through.
