How to Convert PNG to PDF
Add the PNG files
Drop up to 30 files, 25MB each. Each row shows the original file size.
Pick the page
Fit to image is selected. A4 and Letter show direction and margin. Fit has no extra margin.
Choose quality and order
Original quality is selected. Move up and Move down change the page order from the keyboard. One PDF per image is the other output.
Download
One picture keeps its name with .pdf. Several pictures in one PDF download as zerobg-images.pdf. The line by the button shows that PDF size. One PDF per image downloads as a ZIP when there is more than one.
Turn PNG Files Into a PDF Without Sending Them
Png to pdf is the step when a form, a teacher, or a mail app wants one PDF and you have PNG files. This png to pdf converter builds that PDF in this browser. The pictures are not uploaded, and the download has no watermark. One PNG becomes one PDF. Several PNGs can share one PDF.
A homework set, a stack of scans, or a run of screenshots is easier to email or drop into a form as one PDF, in the order you choose. Renaming photo.png to photo.pdf leaves PNG bytes. This page writes a PDF. The Portable Network Graphics article on Wikipedia describes the PNG, and the PDF article on Wikipedia describes the PDF.
A transparent part of a PNG is painted white, because a PDF page is white. Original quality stores the pixels without JPEG compression, so a screenshot of text stays sharp and the PDF is larger. Smaller file uses JPEG compression, which suits a photo. This page does not quote a percentage.
A cutout is a different job. The background remover makes a transparent PNG and uploads the picture. A logo that should stay a picture, not a page, is the PNG maker. One PNG that should become a JPG, without a page size, is PNG to JPG. Two pictures placed side by side on one canvas, rather than as PDF pages, is combine images.
Several PNG Files in One PDF
Use png to pdf when the next person should open one file. Homework photographed as one PNG per page, a scan of a signed form, or a run of screenshots is easier to email or drop into an upload form as one PDF, in the order a reader should see them.
The first row is page one. Move up and Move down change that order from the keyboard. notes.png alone becomes notes.pdf. Several pictures in one PDF download as zerobg-images.pdf.
Fit to Image, A4, and Letter
Fit to image makes the page the same size as the picture. This page counts 96 pixels as one inch, so there is no extra paper and no margin. Fit is the choice when the PDF will be read on a screen, or when you do not want a white frame from the paper size.
A4 is the paper size used in most of the world. Choose it when you will print, or when a form asks for A4. Letter is the paper size used in the United States. Choose it when you will print on US paper, or when a form asks for Letter. Auto puts a wide PNG on a landscape page and a tall PNG on a portrait page. Portrait and Landscape force that direction.
None uses the whole page. Small leaves a half-inch margin. The picture is scaled to fit and centered, and it is not enlarged past 96 pixels per inch. A small PNG stays small in the middle. A large PNG shrinks and keeps its shape.
Transparent Parts of a PNG Become White
A PNG can leave parts of the picture empty. This page paints white first, then draws the PNG, because the PDF page is white. Empty areas, and pixels that were only partly see-through, show as white. A logo with no background becomes a logo on a white rectangle.
White on white disappears. If those empty parts must stay empty, keep the PNG. This page will not write a transparent PDF page. The background remover can cut a subject out, and that tool uploads the picture. This png to pdf page does not upload it.
Original Quality or a Smaller File
Original quality is selected when the page opens. Pixels are stored without JPEG compression, so letters, screenshots, and line art stay sharp. The PDF is larger. Use it for a page of type or a screenshot you may zoom.
Smaller file stores a JPEG inside the PDF. Use it for a photograph, or when mail or a form refuses a large PDF. Text and screenshots should stay on Original quality, because JPEG can halo a hard edge. This page does not give a percentage. The PDF size on a merged download is the measurement. If this browser cannot store the lossless pixels, it uses the smaller JPEG and says so once.
Before You Download the PDF
Set the order first
Page one is the first row. Move up and Move down before you download a shared PDF.
Print on A4 or Letter
Fit has no paper margin. A4 is usual outside the United States. Letter is usual in the United States.
Screenshots want Original quality
Type stays sharper without JPEG. Use Smaller file for photos. There is no percentage.
Expect white in empty areas
A logo with no background sits on white. Keep the PNG if the holes must stay empty.
What This PNG to PDF Page Does Not Do
The pictures are not uploaded. The download is a PDF of those pictures, not a renamed PNG.
- Up to 30 files, 25MB each. A larger file is refused before conversion. One row can fail without stopping the others.
- Transparent areas show as white. This page does not write a transparent PDF page.
- Original quality stores pixels without JPEG compression, so the PDF is larger and text stays sharper. Smaller file uses JPEG. This page states no percentage.
- The PDF contains only pictures. Text you can see in a screenshot is not searchable and cannot be copied out. This page does not run OCR.
- A small picture is not enlarged to fill A4 or Letter. It stays at its size and sits in the center. A large picture is scaled down to fit. Fit ignores margin.
- An animated PNG becomes one still page, the frame this browser draws. A picture past the canvas limit is scaled down, and the page says so. Camera model and GPS are not copied.
- This page does not remove a background, add a watermark, or ask you to sign in.
A PNG, One PDF, and a PDF per Picture
| PNG you drop in | One PDF | One PDF per image | |
|---|---|---|---|
| What you download | The PNG stays a PNG | zerobg-images.pdf, or the original name if there is one picture | One PDF, or a ZIP when there are several |
| Order | The order you dropped them | Move up and Move down set the pages | Each file stands alone |
| Transparency | Can be empty | Empty parts show as white | Empty parts show as white |
| Text in the picture | Pixels, not live text | Still pixels. Not searchable | Still pixels. Not searchable |
Renaming a PNG to .pdf does not make a PDF. This page writes one.
