How to use PNG to PDF Converter
Turn multiple PNG pictures into an organized PDF with configurable A4, US Letter or original-sized pages, adjustable margins and file order.
- Add a PDF or image, or select multiple files when you need a bulk operation.

- Click Process files and wait for the browser to finish each operation.
- Review output file names and sizes, then download individual results or the ZIP archive.
How PNG to PDF Converter works
PNG images preserve transparency as embedded image data. This converter places one image on each PDF page, scaling it to fit without cropping.
Workflow example: A 1200×1800 PNG placed on an A4 page keeps its aspect ratio. Combine several PNGs in the order shown in your queue.
Realistic limits: Browser-based processing may be affected by PDF encryption, uncommon fonts or encodings, device memory and file complexity. Input limit is 35 MB per file, 160 MB combined, up to 15 files. Multiple resulting pages or images may increase output size. Download results before leaving this page.
Frequently asked questions
Does it combine multiple PNG files into one PDF?
Yes. Upload several PNG files and change their order using the up/down controls. One PDF is generated with one image per page.
Will transparent areas remain transparent?
PNG transparency can be preserved inside the PDF. Appearance depends on the PDF viewer and page background.
Can I work with multiple files?
Yes. Up to 15 files per batch, with a 35 MB limit for each input and a combined 160 MB limit. Some operations combine everything into one output PDF; others generate individual files or a ZIP.
Are documents sent to Solvory servers?
This application processes PDF inputs in your browser. Libraries are downloaded from external CDNs, which can receive normal connection metadata. Your uploaded files are not transmitted to a Solvory conversion endpoint by these tools.
Why did my PDF fail to convert?
Password protection, corrupt files, unsupported features, very large page dimensions, complex fonts or insufficient device memory can cause errors. Use a smaller valid PDF or another supported browser.
Privacy, compatibility and safety
Files are handled locally through browser PDF APIs and open-source libraries loaded from CDNs. These tools do not intentionally upload PDF contents to Solvory servers. Some PDFs can have restricted or unsupported features. Browser processing does not promise permanent redaction, lossless reformatting or exact output sizes.
