Can I combine multiple PNG files into a single PDF?

Yes — enable multi-file mode and add multiple PNGs. Each becomes one page in the output PDF, in the order you add them.

Will my PNG look sharp when printed from the PDF?

It depends on the resolution of your PNG. Screen-captured PNGs at 72 DPI will look blurry when printed. For sharp printed output, use PNGs at 300 DPI or higher.

What page size will the PDF be?

By default, the PDF page is sized to match your PNG dimensions. You can also set standard paper sizes (A4, Letter) in the converter settings.

Can I convert a PNG diagram or wireframe to PDF?

Yes — this is a common use case. Design wireframes, technical diagrams, flowcharts, and mockups exported as PNG can be converted to PDF for professional sharing or archiving.

Is the text in my PNG searchable in the PDF?

No. The PNG is embedded as an image — text in the image is not recognized as searchable text. The PDF is essentially an image-inside-document.

Why does my client ask for PDF instead of PNG?

PDF is the standard for professional document exchange — it looks identical on every device, can't be accidentally edited, and is universally accepted by printers, legal systems, and enterprise software.

Is my PNG uploaded to a server?

No. All conversion happens in your browser using client-side libraries. Your images stay on your device.

Frequently Asked Questions

Yes — enable multi-file mode and add multiple PNGs. Each file becomes one page in the output PDF, in the order you add them. This is the fastest way to bundle wireframes, diagrams, or screenshots into a single shareable document.

It depends on the source resolution of your PNG. Screen-captured PNGs are typically 72 DPI — they look fine on screen but will appear blurry when printed on paper. For crisp print output, use PNGs at 300 DPI or higher, which is standard for print-ready design exports.

By default, the PDF page is sized to exactly match your PNG's pixel dimensions. You can also select a standard paper size — A4 (210×297mm), US Letter (8.5×11in), or A3 — in the converter settings before downloading.

Yes — this is one of the most common use cases. Design wireframes, technical diagrams, flowcharts, architecture maps, and UI mockups exported as PNG all convert cleanly to PDF for professional sharing, client review, or archiving.

No. The PNG is embedded as a raster image inside the PDF — any text that appears in the image is not machine-readable and cannot be searched or selected. The result is essentially an image-in-a-document container.

PDF is the universal standard for professional document exchange. It renders identically on every device and OS, cannot be accidentally edited, is accepted by all printers, and is required by most legal, financial, and enterprise systems. Sending a PNG instead of a PDF often signals an informal or unpolished submission.

No. All conversion happens client-side in your browser. Your images are never transmitted to any server — this is especially important for confidential diagrams, design assets under NDA, and proprietary wireframes.
