PNG to PDF Optimization FAQ
How do I convert PNG to PDF for sharing or printing?
+
Upload the PNG file and the converter renders it onto PDF pages with sensible defaults: A4 / letter page size, 1-inch margins, embedded fonts. Multi-page sources (DOCX, EPUB, XLSX) preserve page breaks; image sources get one centered image per page.
Will the PNG to PDF conversion keep my fonts and formatting?
+
Yes for text-bearing PNG (DOCX, ODT, HTML, TXT, EPUB) — fonts are embedded into the PDF so the output looks identical on every viewer. Image-only PNG (JPG, PNG, WebP) just centers the image on the page; there is no text layout to preserve.
Can I merge multiple PNG files into a single PDF?
+
Yes — drop multiple PNG files into the upload zone and pick the "merge into one PDF" option. They appear as sequential pages in upload order; drag-to-reorder is supported in the picker before conversion runs.
What page size and orientation will the PDF use?
+
Defaults: A4 portrait (international) or letter portrait (US). Advanced options expose A3, A4, A5, letter, legal, tabloid, and custom dimensions, plus portrait / landscape. For image PNG, "auto-fit" picks the orientation that matches the source aspect ratio.
Will hyperlinks in my PNG survive the PDF conversion?
+
Yes for PNG formats with real hyperlink metadata (DOCX, ODT, HTML, EPUB). Image-based PNG (JPG, PNG, WebP, TIFF) have no link information to preserve. The PDF uses the standard PDF anchor model so links work in every PDF reader.
Is the PDF searchable / selectable text?
+
Yes when the PNG contains real text (DOCX, ODT, HTML, TXT, EPUB). Image-based PNG produces an image-only PDF — to make it searchable, run /pdf-ocr/ after conversion to apply optical character recognition.
Can I password-protect the PDF after conversion?
+
Not in this tool — convert PNG to PDF first, then use the dedicated /pdf-* tools to add a password, watermark, or restrict editing on the resulting file.
How big will the PDF file be?
+
Depends on the PNG. A 10-page DOCX with embedded fonts produces a 200-400 KB PDF. A 10-image JPG / WebP batch at full resolution produces a 5-20 MB PDF. The "compress images in PDF" toggle in advanced options recompresses embedded images at JPG quality-85 to shrink the PDF further.
Is my PNG file private during PDF conversion?
+
Yes — same privacy model: isolated workers, automatic deletion within minutes, no human review.
Will the PDF pass print-shop preflight (300 DPI, CMYK)?
+
Defaults are RGB / 72 DPI (screen-optimized). For commercial print, switch the advanced options to CMYK / 300 DPI and the converter re-renders text at print resolution and converts embedded images to CMYK colorspace.
Does the converter work with scanned PNG pages?
+
Yes — a scanned-page PNG (JPG, PNG, TIFF, WebP) converts straight to PDF. If you need the PDF to be text-searchable, follow up with /pdf-ocr/ to run OCR over the scanned pages.
Can I convert PNG to PDF and email it directly?
+
Not from the converter UI itself. After download, attach the PDF to your usual email client. The PDF file is portable and works with every modern PDF reader (Acrobat, Preview, Chrome, Edge, Firefox).
