Convert PNG to PDF on iPhone - Free

Yes. PixelPDF intelligently handles PNG transparency during conversion. Transparent areas in your PNG files are preserved in the PDF output, making it ideal for logos, design assets, and graphics with transparent backgrounds. You can also choose to render transparency as a white background if preferred.

Open PixelPDF, tap the photo library button, and select one or more screenshots from your Photos app. iPhone screenshots are saved as PNG files by default. PixelPDF will convert them to PDF instantly while preserving the full resolution and pixel-perfect clarity of your screenshots. You can combine multiple screenshots into a single multi-page PDF.

Absolutely. PixelPDF supports batch PNG to PDF conversion, allowing you to select up to 50 PNG images at once and combine them into a single, organized PDF document. You can reorder pages, adjust quality settings, and choose your preferred page size before generating the final PDF.

PixelPDF offers multiple quality levels for PNG to PDF conversion: Original (preserves full PNG resolution with no compression), High (minimal compression with excellent quality), Medium (balanced quality and file size), and Low (smaller file size for sharing). For design files and graphics, we recommend the Original or High setting to maintain maximum detail.

PNG is the superior format for PDF conversion when you need lossless quality, transparency support, or pixel-perfect detail -- ideal for screenshots, design files, graphics, and text-heavy images. JPG is better for photographs where smaller file sizes are preferred. PixelPDF handles both formats optimally, applying the right processing for each.

PDF file size depends on the quality setting you choose and the dimensions of your PNG images. At Original quality, the PDF will be similar in size to the source PNGs. Using Medium or Low quality reduces file size significantly -- often by 50-80% -- while maintaining good visual quality. PixelPDF gives you full control over the quality-size tradeoff.
