Why You Need to Convert PDF to Image
PDFs are great for reading and archiving, but some scenarios call for images: drop a page into a slide or document, send a preview in chat to someone who doesn't have a PDF reader, or save a single page as image content. Converting the whole document is usually overkill — you probably only need a few pages.
Page-by-Page Selection: Only What You Need
The conversion flow in Image to PDF works like this: once you pick the PDF, the App renders a thumbnail preview of every page. You browse through them and check the ones you want to export. Select All and Clear are both one tap away.
Only need page 3 and page 7? Check those two and export just them. Compared with "export the whole thing and delete the rest", page selection saves the cleanup step and avoids generating a pile of unused images.
Scale Factor: The Balance Between Clarity and File Size
Before exporting, you choose a render scale factor. The App offers five settings: 1.0x, 1.5x, 2.0x, 2.5x, 3.0x. This number determines the resolution of the output PNG:
- 1.0x: Renders at the PDF page's native size. Usually enough for on-screen viewing, smallest file size.
- 1.5x–2.0x: A safe choice for everyday sharing. Looks clear on most screens.
- 2.5x–3.0x: For zoom-in inspection and printing — small text in scanned pages, chart annotations. They can go blurry at low scale factors; higher scale preserves more detail, at the cost of larger files.
Simple rule: pick scale by purpose. Sending to chat for a quick look, 1.0x or 1.5x is enough. Printing or zoom-in detail work, go 2.0x or above.
Output Format and Privacy
Pages export as PNG — a lossless format with crisp text edges, well suited to document pages that contain text. The whole render happens locally on your device, so the PDF is not uploaded to a server — important for files containing sensitive content.
Conversion results are saved to local history automatically, so you don't have to reconvert next time you need them.
