How to convert PNG to PDF
- Optional: sign in with Google to convert up to 10 PNG files per day and bundle them into a ZIP of PDFs.
- Drop your PNG image into the upload box or click to browse. Maximum file size is 50 MB.
- Click Convert. We wrap the PNG losslessly into a single-page PDF.
- Download the PDF. It opens in any reader, prints to standard paper sizes, and uploads to portals that require PDF.
Why convert PNG to PDF
PDFs are the format upload portals, email systems, and print shops actually want. A screenshot, a scan, a chart, or a saved web graphic as a PNG often gets rejected by forms that demand PDF — wrapping it in a PDF is the fastest fix.
PNG-to-PDF also makes printing predictable. PNG sent to a printer scales somewhat unpredictably; PDF lays out the image on a chosen page size so it comes out the way you expect.
Email systems and document workflows handle PDF more reliably than PNG. Some corporate mail filters strip image attachments; PDFs always get through. Some review platforms preview PDF inline but require a download for PNG.
Heads up: this conversion currently makes one PDF per PNG. If you have several PNGs that need to merge into a single multi-page PDF (a common request for receipt batches or scanned documents), our merge mode is on the roadmap. For now, convert each PNG and combine the PDFs with any merger.
Common use cases
- Submit a PNG screenshot as a PDF when an online form requires PDF.
- Print a PNG cleanly on US Letter or A4 paper without scaling surprises.
- Email a PNG chart or diagram as a PDF that always renders inline.
- Archive a PNG screenshot or graphic in a portable, long-lived PDF.
- Submit a PNG of a receipt or document as a PDF for an expense report.
Tips for best results
- We embed the PNG losslessly — no recompression. The PDF is exactly as sharp as the input.
- By default the PDF page matches the PNG aspect ratio (no stretching). For a fixed US Letter or A4 page, use a PDF editor afterward — Pro tier will expose this option.
- Transparency in the PNG flattens to a white background in the PDF (PDF supports transparency in some viewers, but it is safest to plan for white).
- Multi-image merge into a single multi-page PDF is on our roadmap; for now, convert each PNG and merge the PDFs with any tool.
- The PDF file will be slightly larger than the PNG — it wraps the image plus a small bit of PDF structure.
About PNG
PNG (Portable Network Graphics) is a lossless raster image format used for screenshots, logos, icons, charts, and any picture where transparency or pixel-perfect quality matters. Created in 1996 as a free alternative to GIF, PNG is universally supported by every browser, operating system, and image tool. The downside for sharing is that PNG is not always accepted by upload forms, email filters, or print workflows that expect a PDF.
About PDF
PDF (Portable Document Format) bundles text, images, and layout into a single portable file that displays identically on every device. Created by Adobe in 1993, it is the standard for receipts, IDs, contracts, resumes, and anything you submit to a portal or print at a shop. A PNG wrapped in a PDF is easier to email, attach, print, or include in a larger document set than a standalone image.

Frequently asked questions
Will the image quality stay the same?+
Yes. We embed the PNG inside the PDF without recompression — the PDF is exactly as sharp as the input.
Is the PNG to PDF converter free?+
Yes. 5 conversions per day as a guest, 10 per day signed in with Google. No credit card.
Can I combine several PNGs into one PDF?+
Not yet. Each conversion produces a single-page PDF from one image. Batch and merge into a multi-page PDF are on the roadmap. For now, convert each PNG separately and merge the resulting PDFs.
Will the PDF be A4, US Letter, or fit-to-image?+
By default we fit the page to the PNG aspect ratio so the image is not stretched. Fixed page-size output is coming in Pro.
Will transparency be preserved?+
Some PDF viewers honor transparency, but for safety the PNG flattens to a white background in the PDF. If you need a true transparent overlay in a PDF, use a dedicated PDF editor.
Is it safe to upload my PNG?+
Yes. Files are uploaded over HTTPS and deleted from our servers within one hour. We never train models on your images.
Does it work on Mac, Windows, iPhone, and Android?+
Yes. The converter runs in any modern browser. The PDF output works everywhere.
How big can the PNG be?+
50 MB on the free tier. Pro lifts this to 500 MB — leave your email on the pricing page for early access.
