PDF to PNG Conversion FAQ
What DPI does the PNG render at?
+
The Resolution menu on the converter page offers 72 DPI for screen use, 150 DPI, which is the default, and 300 DPI for print. Higher resolutions give sharper but larger PNG files. PNG uses DEFLATE compression over filtered scanlines, so every pixel survives exactly, plus a full 8-bit alpha channel.
Does the PNG output support transparency?
+
The format does, but the source has no alpha to give it — video frames and rendered pages are fully opaque by nature, so every pixel arrives solid. The alpha channel is still useful afterwards: it means you can cut a subject out of the PNG later without changing format again. PNG is the right choice for screenshots, logos, line art and anything with hard edges or transparency — no ringing, no colour banding.
How big will the PNG files be?
+
Larger than you might expect, because PNG keeps every pixel exactly rather than approximating. A 1080p still lands around 2-5 MB and a 4K still around 6-15 MB, so a long extraction run adds up quickly. That is the right trade when the images feed further processing, and the wrong one when they are going straight onto a web page.
Can I convert only part of the PDF instead of all of it?
+
Only down to the first page. The Pages menu offers All pages or First page only, which is enough for a cover or a thumbnail. For any other page, split the PDF first with /pdf-split/ and convert just the pages you need.
Is the PDF side of this conversion searchable?
+
It depends entirely on whether real text is present. A PDF generated from a document carries an actual text layer and is searchable; a PDF built from scans or images is a picture of text and is not, until OCR adds a layer. /pdf-ocr/ does that, and it is worth running before any conversion that expects to read the words.
Do I get one image per page?
+
Yes. Each page renders as its own PNG file, numbered in page order, so a one-page document gives a single PNG and a longer one gives one image per page.
Can I convert only some pages of the PDF to PNG?
+
The Pages menu has two choices: all pages, which is the default, or the first page only. There is no way to type in a page range. For other pages, split the PDF into single pages with /pdf-split/ and convert the pages you need.
Will the PNG preserve PDF text searchability?
+
No — rasterizing PDF to PNG turns text into pixels. If you need searchable output, keep the PDF as a PDF and use a text-extraction tool instead. Image output (PNG) is for visual display or further image processing.
