72 points is an inch. 56 is about 2 cm, which is a normal book margin.

  • No upload The conversion runs in this tab. Your file never travels — not to us, and not to the advertising.
  • No sign-up, no email, no daily cap There is no account system to sign up to.
  • No size limit we invented Only your device's memory — about ~2 GB on a desktop browser, ~400 MB on a phone.
  • Turn your Wi-Fi off and convert anyway The conversion needs nothing but this page. Ads will not load without a connection; your file will still convert. That is the whole claim, and it takes five seconds to check.

Wraps a PNG in a PDF, losslessly. PDF supports the same Flate compression PNG uses, so the pixels go in exactly as they are — nothing is decoded, re-encoded or approximated.

Screenshots are the common case

Most PNGs that need to become PDFs are screenshots: a receipt, a confirmation, a chat, an error message, evidence for a claim. PNG is right for those because it keeps text sharp; PDF is what the recipient's system accepts.

For a screenshot, choose page exactly the size of the image. A screenshot on an A4 page with margins looks like a mistake, and shrinking it to fit makes the text harder to read than it was.

Transparency

PNG has an alpha channel; PDF pages do not have a background you can see through. Transparent areas render against white, which is what a PDF viewer and a printer both assume.

That is almost always right. Where it is not — a logo meant to sit on a coloured background — flatten it onto the colour you want first, using the PNG to JPG tool with a background colour set.

Lossless in, lossless out

No quality is lost. Some converters decode the PNG and re-encode it as JPEG inside the PDF, which makes the file smaller and puts compression artefacts on the text in your screenshot — exactly where they are most visible. That does not happen here.

The consequence is that a PDF from a large PNG is a large PDF. If size matters more than fidelity, convert the PNG to JPEG first and use the JPG to PDF page.

Questions

Is the image re-compressed?
No. PDF supports the same lossless compression PNG uses, so the pixels are embedded exactly.
What happens to transparent areas?
They render against white, which is what PDF viewers and printers assume. Flatten onto a colour first if you need something else.
The PDF is very large.
Lossless embedding means a large PNG makes a large PDF. Convert to JPEG first if size matters more than fidelity.
Best settings for a screenshot?
Page exactly the size of the image. A screenshot centred on an A4 page with margins looks like a mistake and is harder to read.
Is my file uploaded?
No. The PDF is built in this tab and handed to you as a download. That matters here more than most places: the documents people convert to PDF are contracts, CVs, medical letters and manuscripts.
Can I convert several files at once?
Yes. Drop as many as you like, or a whole folder. Each becomes its own PDF keeping its original name.
