Why Convert PNG to PDF?
PDF is the easiest way to package PNG images into something shareable, printable, and consistent across devices. It works well when you need one file instead of many, print-friendly output, or a document that opens the same way for clients, coworkers, and customers.
Best Use Cases for PDF
- • PNG to PDF Online: Turn one or more PNGs into a document without installing desktop software
- • Combine Multiple PNGs: Merge screenshots, scans, or slides into one PDF file
- • Printing: Use A4 or Letter settings for cleaner print output
- • Client Delivery: Share one portable file instead of a folder of images
- • Archiving: Keep image-based records in a universal document format
Common PNG to PDF workflows
PNG to PDF online
Use the single-image flow when you just need one screenshot, receipt, design, or scan wrapped into a PDF quickly.
Combine multiple PNG files
Switch bulk mode to a single multi-page PDF when you want one downloadable document instead of separate files.
Prepare for printing
Choose A4 or Letter, keep reasonable margins, and use higher quality for diagrams, text-heavy images, or customer-facing printouts.

Settings Explained
📄 Page Size
Auto-fit: PDF dimensions match image dimensions exactly (no cropping, no white space)
A4: Standard international paper (210 × 297 mm). Image is scaled to fit with margins.
Letter: Standard US paper (216 × 279 mm). Image is scaled to fit with margins.
🔄 Orientation
Portrait: Vertical pages (taller than wide)
Landscape: Horizontal pages (wider than tall)
Note: Disabled when using Auto-fit (orientation is auto-detected)
📐 Margin (0-20mm)
What it does: Adds white space around the image on the PDF page.
Recommendation: 10mm for printing, 5mm for screen viewing, 0mm for no margins
Note: Disabled when using Auto-fit
⚡ Quality (50%-100%)
What it does: Controls JPEG compression level when converting PNG to PDF. Higher quality = larger files, lower quality = smaller files.
Default: 85% - Perfect balance between quality and file size
100%: Best quality, minimal compression (larger files)
85%: Excellent quality, 50-80% smaller files (RECOMMENDED)
50%: Smallest files, noticeable quality loss
💡 Tip: For photos, 75-85% is ideal. For text/diagrams, use 90-100%.
🎨 Background Color
What it does: Sets the background color for transparent areas in PNG images.
Default: White (#FFFFFF)
Why it's needed: PDF uses JPEG compression which doesn't support transparency. Transparent pixels are filled with this color.
When to change:
• Use white for documents on white paper
• Use black for dark-mode PDFs
• Match your presentation background color
💡 Tip: If your PNG has no transparency, any color works.
📚 Bulk PDF Mode
Separate PDFs: Each PNG → 1 PDF file. Download all as ZIP.
Single Multi-page PDF: All selected PNGs → 1 PDF with multiple pages. One PDF to download.
Use case: Separate PDFs for individual images, Multi-page PDF for documents/presentations
