PNG to PDF Converter

1. Upload one or more PNG files (up to 50 MB total).
2. Click 'Convert PNG to PDF' — takes 2-5 seconds per image.
3. Download the PDF — all images combined into one document.

PNG's lossless quality and transparency make it the best format for logos, diagrams, and screenshots. Converting to PDF makes PNG images universal and lets you combine multiple into one document.

PNG is the best format for lossless images with transparency — logos, icons, diagrams, screenshots. But PNGs aren't ideal for documents, sharing, or printing. Converting to PDF makes PNG images universal, printable, and easy to combine into a single document. Perfect for creating PDF portfolios, documenting screenshots, or archiving a design collection.

The converter decodes each PNG image and embeds it in a PDF page using img2pdf. Lossless quality is preserved. Transparency is rendered on a white background (PDF pages don't have transparency by default). Multiple PNG files are combined into a single PDF. Output is PDF 1.7.

PNG → PDF preserves the lossless quality of the source. Colors are exact. Transparency is rendered on a white background (this is a PDF limitation, not a quality issue).

• Transparency becomes white background.
• 16-bit PNGs are converted to 8-bit.
• PDF is image-based — text within PNG isn't searchable.
• Combining many large PNGs creates a large PDF.
• For editable text, use OCR after conversion.

• Output PDF opens in every browser, reader, and OS.
• Printable with full fidelity.
• Accepted by every document management system.
• Shareable by email, cloud, or file transfer.
• Standard PDF — no special software needed.

• Multiple PNG files can be combined into one PDF.
• Transparent PNG images get a white background in the PDF.
• Lossless quality is preserved — colors are exact.
• For photos, JPG gives smaller files than PNG.
• For transparency-sensitive work, use PNG-to-PNG tools instead.

Transparency became white

PDF pages don't support transparency by default. Transparent PNG areas are rendered on white.

PDF is very large

PNGs are lossless and can be large. Combine fewer images per PDF, or convert to JPG first for smaller files.

16-bit PNG lost precision

PDF output is 8-bit per channel. For 16-bit workflows, keep the original PNG.
