PNG to PDF Converter - Free Online Tool

A PNG to PDF converter turns one or more PNG images into a single PDF document. It is a practical way to package screenshots, design mockups, diagrams, and scanned pages into one shareable file. PDF generation runs locally in your browser, so your PNG files are not uploaded for conversion.

1. Add your PNGs: Choose one or more .png files.
2. Reorder pages: Use the up and down arrows to set the page order.
3. Choose page settings: Pick page size (Fit, A4, or Letter), orientation, and margins.
4. Convert and download: Click Convert, then download your PDF.

• Great for screenshots: PNG keeps sharp text and UI edges, which is ideal for docs and bug reports.
• Flexible page layout: Fit to image for exact sizing, or A4/Letter for standard pages.
• Private conversion: PDF generation happens on your device in the browser.

Use these options to control how PNGs sit on each PDF page:

• Fit to image: Each PDF page matches the PNG dimensions. This avoids scaling and keeps screenshots crisp.
• A4 or Letter: Creates standard pages and scales the PNG to fit while keeping aspect ratio.
• Orientation: Auto chooses portrait vs landscape per image. Choose a fixed orientation if you want a consistent layout.
• Margins: Add whitespace around the PNG. This is useful for printing or when you do not want edge-to-edge content.

If your PNG has transparency, the PDF page background will still render as the page color in most viewers (usually white). That is normal.

Use case 1: Share a set of screenshots

Bundle UI screenshots into a single PDF for issue reports, support tickets, or client reviews.

Use case 2: Submit forms and diagrams

Convert exported diagrams, signatures, or scanned paperwork into a PDF that works with most upload portals.

Use case 3: Archive design iterations

Export mockups as PNG, then create a PDF you can version, annotate, and store with project notes.

Basic example (screenshots)

Inputs: bug-1.png, bug-2.png, bug-3.png
Settings: Page size: Fit to image; Orientation: Auto; Margin: 0
Output: A PDF where each page matches its screenshot size.

Advanced example (standard pages)

Inputs: diagram.png, mockup.png
Settings: Page size: Letter; Orientation: Landscape; Margin: 16 pt
Output: A letter-size PDF with margins that prints cleanly.

PNG is ideal when you care about sharp edges: UI screenshots, diagrams, and text-heavy images. For photos, JPG is usually smaller; convert photos with JPG to PDF or convert PNGs to JPG first with PNG to JPG when transparency is not required.

"This tool accepts PNG images only"

If your images are JPG, WebP, or HEIC, convert them first. For photos, JPG to PDF is usually the better match.

The PDF is much bigger than the PNGs

PNG files can be large, especially for high-resolution screenshots. If file size matters, resize the images first using the image resizer & compressor or convert PNGs to JPG with PNG to JPG when transparency is not required.

Content looks too tight on the page

Increase the margin setting or switch Page size to A4/Letter so there is more whitespace around the image content.

File too large

If a PNG is over the per-image size limit, reduce it first. Resize the source image or export at a smaller resolution, then convert again.

• Keep the sharpness: PNG is a strong choice for UI captures and text-heavy images.
• Use standard sizes for printing: Choose A4 or Letter when you plan to print or upload to strict portals.
• Shrink first when needed: Resize screenshots before converting to avoid oversized PDFs.

• Turn photos into PDFs with the JPG to PDF converter.
• Combine multiple PDFs with merge PDF files.
• Convert images for smaller files with PNG to JPG or PNG to WebP.

PNG to PDF conversion runs locally in your browser. Your images are not uploaded to a server. If you are converting sensitive documents, download the PDF and close the tab when you are finished.
