Export PDF pages as PNG images on iPhone with ScanLens. Use PNG when the receiving app requests that format, or when you want to avoid another JPG encoding of a diagram or text-heavy page. Check the rendered image before sharing.
PNG encoding is lossless, but the complete PDF-to-image conversion is not guaranteed to preserve every source detail. The page is rasterized, may be resized, and ScanLens can use a JPEG intermediate before PNG encoding. PNG cannot restore detail already lost. Keep the original PDF when vector sharpness or exact source fidelity matters.
The export quality setting affects image dimensions. Lower quality can reduce file size by reducing resolution; higher quality does not make a low-resolution source sharper. There is no fixed PNG-to-JPG size ratio: compare the actual outputs. Use JPG export when a smaller photo-style attachment is more useful.
Apple Preview: export as PNG. Check the saved image against the source page.
No. The PDF page rendering path fills the background with white. Do not use this export workflow when you need to retain a transparent background.
The PNG contains pixels, not the PDF’s text layer. Use OCR to recognize the text, and proofread the result. Keep the PDF if you need its existing selectable text.
Conversion runs on the iPhone. Optional cloud backup or automatic uploads can transfer documents separately, and saving to iCloud Drive or sharing sends the output to your chosen destination.
