What's the difference between PNG and PDF?
PNG (Portable Network Graphics) and PDF (Portable Document Format) solve different problems: PNG is a lossless compression format built for screenshots, logos, graphics with transparency, while PDF is a document format format whose strength is documents, contracts, printing, sharing. In practice you will meet PNG when dealing with screenshots, logos, graphics with transparency, and reach for PDF when you need documents, contracts, printing, sharing — the table below compares them point by point.

Why convert PNG to PDF?
PNG (Portable Network Graphics) is a lossless raster image format standardized in 1996 as a patent-free replacement for GIF. It preserves every pixel exactly, supports full alpha transparency, and is the default choice for screenshots, logos, and graphics with sharp edges or text. Here is when PDF is the better choice:
- →A PDF looks the same on every phone, computer, and printer — no layout surprises.
- →Images become easy to print, sign, attach, and archive once wrapped in a PDF page.
- →It runs in the cloud — 10 free conversions a day with files up to 200 MB (20/day and 500 MB with a free account) — so even a phone or an old laptop converts at full speed.
Before you convert: three quick tips
- ●If your image has a transparent background, pick a target that supports it (PNG, WebP, AVIF); converting to JPG fills transparency with white.
- ●For web use, the modern formats (WebP, AVIF) save the most bandwidth; for maximum compatibility, JPG and PNG remain the safe choices.
- ●Keep your original PNG — conversion never modifies it, and if you later need a different target format, starting from the original always gives the best quality.
PDF conversion settings explained
For image-to-PDF, the page is sized to your image exactly (at 72 DPI) — no cropping, no scaling, no white margins. JPG and PNG sources are embedded with their original data (lossless); other image formats are first converted losslessly to PNG, then embedded.
The output is a standard PDF 1.7 document that opens in every PDF reader, browser, and print driver. Landscape images produce landscape pages and portrait images produce portrait pages; when printing, your printer driver handles scaling to paper size — nothing to prepare in advance. Need several images in one document? Choose "Combine into one PDF" in the converter above — it merges your images into a single multi-page PDF, one image per page, with an optional A4 or Letter page size.
How the conversion works
Filevo builds your PDF with pdf-lib, embedding the PNG image data directly into a freshly generated document — JPG and PNG bytes go in as-is, with no recompression, and the page is sized to the image exactly. The process is deterministic: the same input always produces the same output.
PNG to PDF: combine screenshots and graphics into one file
PNG is the format of screenshots, charts, diagrams, logos, and UI exports — and most of the time you have several of them that belong together. Drop your PNGs into the converter above and choose "Combine into one PDF": Filevo merges them into a single multi-page document, one image per page, in order. It is the fastest way to turn a thread of chat screenshots, a set of dashboard charts, a sequence of wireframes, or a batch of receipts into one file you can attach to a report, drop into a deck, or file away. Up to 50 PNGs per PDF. Converting PNG to PDF this way is the simplest way to share a set of images: a PNG to PDF document opens identically on every device, and because Filevo runs PNG to PDF in the browser, nothing is installed and your files are gone within 24 hours.
PNG to PDF keeps your text and edges razor-sharp
This is where PNG to PDF beats JPG to PDF. Screenshots and graphics are full of sharp text and hard edges, and lossy re-encoding smears them into fuzzy, artifact-ringed mush. Filevo never re-encodes: it embeds your original PNG bytes directly into the PDF with pdf-lib, losslessly. The text in your screenshot stays crisp enough to read at any zoom, the lines in your chart stay clean, and a flat-color logo stays flat — exactly as the PNG had it. For anything with type or fine linework, that lossless path is the difference between a professional-looking PDF and a blurry one. It is why PNG to PDF, done losslessly, is the right choice for screenshots and charts.
What happens to a transparent PNG background?
Here is the honest answer, because it is PNG-specific and most tools dodge it. Filevo keeps your PNG's transparency in the embedded image data — it does not flatten or recolor your pixels. But a PDF page is white paper: when a viewer or printer renders the page, anything transparent shows the white page behind it. So a logo with a see-through background will look like it is sitting on white, because on a PDF page, it is. That is normal and expected. If you truly need the transparency to travel with the image — to drop it onto a colored design later — keep the PNG itself, or convert PNG to WebP; a PDF page is meant to be printed, and print is white.
PNG to PDF page size and orientation, with no upscaling
Pick how each PNG sits on the page. Match image makes the page exactly the size of the image — edge to edge, no white border — which is perfect for a single screenshot you want reproduced faithfully. A4 and US Letter put it on a print-standard page, scaled to fit and centered. Crucially, Filevo never enlarges an image past its real size: a small screenshot or icon on an A4 page stays at its native resolution and stays sharp, rather than being upscaled into blur. Portrait and landscape pages follow each image automatically. That keeps PNG to PDF predictable whether you view it on screen or send it to print.
| Page size | What you get | Best for |
|---|---|---|
| Match image | Page = image size, fills edge to edge, no margin | a single screenshot, exact reproduction |
| A4 | Image scaled to fit & centered on A4, never enlarged | printing, reports, decks |
| US Letter | Image scaled to fit & centered on Letter | printing in the US / Canada |

What is PDF?
PDF (Portable Document Format) is a document format created by Adobe in 1993 and standardized as ISO 32000. A PDF renders identically on every device and OS, which is why it is the universal format for contracts, invoices, forms, reports, and anything meant to be printed or signed.

PNG to PDF converter FAQ
How do I convert PNG to PDF for free?
Drop your PNG file into the converter at the top of this page, confirm PDF as the target, click Convert, and download the result. It is genuinely free: 10 free conversions a day with files up to 200 MB (20/day and 500 MB with a free account), no watermarks, no software to install, no account required.
Is it safe to convert PNG files online?
Yes. Transfers are TLS-encrypted end to end, and conversion is fully automated — no human ever sees your files. Your uploaded PNG is deleted the moment conversion finishes, and the converted PDF auto-deletes after 24 hours (you can delete it sooner). We never use your files for AI training or share them with anyone.
Will I lose quality converting PNG to PDF?
Your image is embedded into the PDF page at its original resolution — the process is lossless, the image inside the PDF is pixel-identical to the source, and the page is sized to match the image exactly.
How long does PNG to PDF conversion take?
Usually seconds. The conversion itself takes from under a second to a few seconds for images and audio — most of the wait is the upload, which depends on your connection speed. Since processing happens in the cloud, your device stays fast, and you can run several conversions in parallel.
Can I convert PNG to PDF on iPhone or Android?
Yes. Filevo runs entirely in the browser, so it works the same on iPhone, Android, tablets, and computers — no app to install. On mobile, tap Browse Files to pick from your photos or files.
What's the maximum file size?
Anonymous conversions accept files up to 200 MB; a free account raises that to 500 MB. Paid plans go from 1 GB up to 10 GB per file, with higher daily limits and priority queues.
Can I convert multiple files at once?
Yes. Drop up to 50 files at once — they roll through the queue automatically. Pick a target format per file or set one per category, then download results individually or grab everything as a single ZIP.
What page size will my PDF use?
Filevo sizes the PDF page to match your image exactly (at 72 DPI), so nothing is cropped or stretched and there are no white margins.
Can I combine multiple PNGs into one PDF?
Yes. Add your PNGs, choose "Combine into one PDF", and Filevo builds a single multi-page PDF with one image per page, in order — up to 50 images at once.
What happens to a transparent PNG background in the PDF?
PNG to PDF handles this predictably: the transparency is kept in the image data, but PDF pages are white, so transparent areas show as white when the PDF is viewed or printed. If you need the transparency itself preserved, keep the PNG or convert to WebP instead.
Will the text in my screenshots stay sharp?
Yes. Filevo embeds your PNG losslessly with no re-encoding, so text and sharp edges are preserved exactly — no JPEG-style blur or artifacts. That is the big advantage of PNG to PDF for screenshots and charts.
Are small screenshots blurry on an A4 page?
No. Filevo never upscales: a small image keeps its real size on the page and stays sharp. If you want it to fill the page exactly, choose the Match image page size instead.
Whether you need documents, contracts, printing, sharing or simply a file that works where PNG will not open, the converter above turns PNG into PDF in seconds — free, private, and with nothing to install. Bookmark this page for the next time a PNG file refuses to cooperate.
