Create Image from PDF

Image → Create Image from PDF

The Create Image from PDF API converts PDF pages to images. Send the PDF as Base64 (docContent), the file name (docname), and—when you care which pages run—fill pageNrs with one line of text the same way you would in the Power Automate Page Number field (all, 1,2-3,5,7-, -2, and so on). imageAction and async are optional extras. The Parameters tab has the same quick guide, examples, and practical notes as the integration docs.

Overview

What is Create Image from PDF?

This endpoint converts PDF pages to images. You provide the PDF (Base64), docname, and optionally pageNrs as one string—plain numbers, commas, ranges, and keywords like all (see the Parameters tab for the full pattern list and a 12-page example table). You can also send imageAction for width, format, or advanced page selection. The response is a JSON array of images (Base64) with file names and page info. Supported output formats include jpeg, png, bmp, gif, tiff, and others.

Key features

• Page selection – Type pageNrs as one line of text (same patterns as the Power Automate Page Number field: all, a lone *, last, first, 0, 1, commas, ranges, 7-, -1, -2, …). Optional imageAction for width, format, or alternate page selection.
• Format and size – imageAction can set WidthPixel and ImageExtension (jpeg, png, bmp, gif, tif, etc.).
• Async – Use async for large PDFs.

:::tip Best for Use when you need thumbnails or images from PDF pages. Combine with Compress Image or Resize Image for thumbnails. :::

Parameters

API parameters

Parameter	Type	Required	Description
api-key	string	Yes	Your PDF4me API key, Base64 encoded. Get it from the dashboard.
docContent	base64	Yes	PDF file content (Base64).
docname	string	Yes	PDF file name (e.g. sample.pdf).
pageNrs	string	No	Pages to convert—one line of text: numbers, commas, hyphens, and keywords (all, a lone *, last, first, 0, 1, -1, -2, …). Same patterns as the Power Automate Page Number field. See the tip and example table below.
imageAction	object	No	WidthPixel, ImageExtension, PageSelection (JSON).
async	boolean	No	Enable asynchronous processing.

:::tip How to fill pageNrs

• Type all to convert every page. A lone * (asterisk) does the same job if you prefer it.
• last is only the final page.
• first, 0, or plain 1 all mean “just the first page.” 0 is simply another way to say page 1; after that you still count 2, 3, 4…
• -1 is the last page. -2 is the page before that (on a 12-page file that is page 11).
• Commas let you stitch pieces together. 1,2-3,5,7- reads as: page 1, pages 2 through 3, page 5, then page 7 all the way to the end. The empty spot after 7- is what tells the service “run to the last page.”

:::

:::info Why we show 1,2-3,5,7- instead of 0,1-2,5,7-

0,1-2,5,7- is legal, but 0 and 1-2 both include page 1, so you can accidentally render the first page twice. 1,2-3,5,7- says the same kind of thing with less overlap.

:::

Example strings (picture a 12-page PDF)

What you type	What you get
1,2-3,5,7-	Page 1, pages 2–3, page 5, then pages 7–12
all	Pages 1 through 12
*	Same as all
-1	Page 12 (last)
-2	Page 11 (second from the end)
last	Page 12 only
first	Page 1 only
0	Page 1 only (same idea as first)

Practical notes

• 7- with nothing after the dash means “from page 7 through the last page.”
• Page numbers that do not exist are ignored.
• 7-3 (backwards) still keeps page 7 from that chunk when page 7 exists; do not expect pages 6 and 5 from that piece.
• Listing the same page more than once is allowed—each mention can produce another image.

Use cases
