Frequently Asked Questions
Can I convert PNG with a transparent background to PDF?
Yes. PNG transparency is handled during conversion. Transparent areas will typically render with a white background in the PDF output, which is standard for print-ready documents.
How many PNG files can I combine into one PDF?
There is no hard limit. You can combine as many PNG images as your browser can handle in memory. For very large collections (100+ images), processing may take a few additional seconds.
Is there a difference between PNG to PDF and JPG to PDF?
The main difference is image quality. PNG files are lossless and support transparency, making them better for screenshots and graphics. JPG uses lossy compression, making them smaller and better suited for photographs. Both can be converted to PDF with LocalDoc.
Can I reorder PNG images before converting?
Images are included in the PDF in the order they were added. To control page order, add your PNG files in the sequence you want them to appear in the final PDF document.
What page size is used for the PDF output?
Each PNG image is embedded on a PDF page sized to fit the image dimensions at 72 DPI. For A4-standardized output, use the image resize option or the Compress PDF tool for post-processing.
