PNG to PDF
Converting a .png image to .pdf re-encodes the pixels for a different balance of size, quality, and support. Free, private, and validated — the file never leaves your browser.

Converting a .png image to .pdf re-encodes the pixels for a different balance of size, quality, and support. A .png file is a losslessly compressed raster image with full 8-bit alpha transparency, making it the standard choice for graphics that must stay pixel-perfect. Screenshots, logos, UI assets, and diagrams are the classic .png territory, since sharp edges and flat color survive without compression artifacts.
A .pdf file is a Portable Document Format document, designed so a page looks identical on every screen and printer. Fonts, images, vector drawings, and layout travel locked inside the file itself, which is why contracts, invoices, and forms are almost always exchanged as PDF. For this route the practical draw is renders identically everywhere, from phones to press equipment and open ISO standard with viewers built into every modern browser — balanced against fixed layout makes editing and text reflow painful after the fact, which is worth knowing before you commit a large batch.
Why convert PNG to PDF?
Embedding a PNG as a single-page PDF is the clean way to email a screenshot or diagram without it being re-compressed by a mail client, or to drop a raster into a print workflow that only accepts PDF. The page size matches the image; nothing is resampled unless you asked for another raster format first.
PNG vs PDF at a glance
| Aspect | PNG image (.png) | PDF document (.pdf) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Container — quality depends on the codecs and settings inside |
| How it stores data | uses DEFLATE compression preceded by per-scanline prediction filters (None, Sub, Up, Average, Paeth) | built from a graph of numbered objects located through a cross-reference (xref) table, so viewers can jump straight to any page without reading the whole file |
| Strongest at | screenshots and screen recordings exported as stills | contracts and agreements that need e-signatures and a tamper-evident layout |
| Weak spot | photographic content produces files several times larger than JPEG or WebP | fixed layout makes editing and text reflow painful after the fact |
| Metadata | text metadata lives in tEXt/iTXt chunks and XMP can be embedded there; standardized EXIF arrived late via the 2017 eXIf chunk, so many tools still drop EXIF when writing PNG | carries both a classic Info dictionary (title, author, dates) and an embedded XMP packet; both survive resaves, and PDF/A actually requires the XMP copy |
Pick PDF as the output
Select .pdf in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if PDF is selectable, the route is real and validated.
Convert on your device
Press Convert. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid PDF file. Outputs keep the original filename with the .pdf extension.
PNG to PDF questions, answered
Will converting PNG to PDF lose quality?
Since png is lossless-oriented and pdf is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .pdf itself requires.
Is it private to convert PNG files here?
Yes — the .png file is processed inside your browser tab and never uploaded. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders. Close the tab and the file is gone from memory.
Where will the PDF file work?
Windows, macOS, Linux, iOS, and Android all preview PDFs out of the box, and Chrome, Firefox (via pdf.js), Edge, and Safari ship their own viewers. Word and LibreOffice can import PDFs for editing, though layout is approximated rather than preserved. In-browser tools can render and extract pages entirely client-side with pdf.js, which is how this site converts them.
Will the PDF file be bigger or smaller than my PNG?
It depends on the content: built from a graph of numbered objects located through a cross-reference (xref) table, so viewers can jump straight to any page without reading the whole file. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my PNG file?
In .png, text metadata lives in tEXt/iTXt chunks and XMP can be embedded there; standardized EXIF arrived late via the 2017 eXIf chunk, so many tools still drop EXIF when writing PNG. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Can I convert PDF back to PNG?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .png → .pdf → .png is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
