Convert a PDF to JPG on iPhone when you need page images for an upload form, message, or slide. In ScanLens, open the document, choose JPG in export, then save the images. Each exported page becomes a separate file.
Output dimensions depend on the source page and quality setting. Higher quality can retain more detail and create larger files; it cannot recover detail missing from a blurry scan. Check the exported JPG at the size where you will use it. If an upload rejects the file, reduce quality and compare readability before submitting.
JPG suits photo-heavy pages when attachment size matters. PNG export avoids an additional lossy JPG encoding at the final step. Both turn text and vector shapes into pixels. Keep the PDF for selectable text and scalable graphics, or use OCR to recognize text from a scan.
Apple Preview: export as JPEG. Review the saved output before sharing it.
Save the image to Photos, open it, choose Edit, then Crop. Check the crop before saving so you do not remove needed text.
No. JPG and JPEG are two filename extensions for the same image format. A .jpg file is a JPEG image.
Yes. ScanLens renders the pages on the iPhone. Cloud backup, automatic uploads, and the destination you choose for sharing can transfer files; check those settings when keeping a document local.
