One workflow, three file pickersOn iPhoneOn AndroidOn a computerConverting a scanned PDF specificallyCommon mistakes across every deviceOne workflow, three file pickers
The actual conversion — upload, choose quality, download — is identical no matter what you are holding. The only real differences between iPhone, Android, and a computer are where the file picker looks for your PDF and where the browser puts the finished JPG afterward. Once you know those two things per device, the rest is the same everywhere.
Same tool, any device
Open the PDF to JPG tool in your phone or desktop browser and follow the steps for your device above.
On iPhone
Open Safari and go to the PDF to JPG tool. Tap Select file and choose Browse if the PDF lives in Files, iCloud Drive, Downloads, Google Drive, or Dropbox.
If your PDF arrived in Mail or Messages, save it to Files first — that makes it far easier for Safari's file picker to find, and gives you one predictable place to look for the original afterward.
Pick a page range and quality setting, then convert. Keep Safari open until it finishes if the file is large — mobile browsers can pause background tabs aggressively.
Safari on current iOS saves downloads to the Files app automatically; tap the download icon in the address bar to find recent downloads if a result seems to have disappeared.
On Android
Open Chrome, Samsung Internet, or another modern browser and go to the same tool. Tap Select file and choose Files, Downloads, Drive, or whichever app has your PDF.
Android's file picker is not standardized across manufacturers — Samsung devices often show a different browser than stock Android or Pixel phones. If the picker cannot find your file, open it directly in Google Drive or Files by Google first, then use the Share menu to hand it to your browser instead.
Convert and download as usual. Most Android browsers show a download notification you can tap directly, or check the Downloads app or your file manager's Downloads folder.
On a computer
This is the simplest case: open the tool in any desktop browser, select the file from wherever it lives locally, and download straight to your Downloads folder. There is no file-picker quirk to work around, which is worth remembering if a phone conversion is giving you trouble — moving the file to a computer briefly can sidestep the whole problem.
Converting a scanned PDF specifically
A scanned PDF is usually already a set of full-page images wrapped inside a PDF container, so converting it to JPG is close to unpacking a picture rather than rendering text. Use standard or high quality depending on how fine the detail is — high quality matters more for small handwriting, stamps, or faint text.
After conversion, zoom in on names, dates, signatures, and any document numbers before you trust the result — these are the details that decide whether the image is actually useful, and scanned pages can hide legibility problems at normal zoom.
Remember that scanned text is not searchable or selectable unless OCR has already been applied to the document — converting to JPG preserves the visual appearance only, it does not create editable text.
Common mistakes across every device
Assuming a downloaded image landed in Photos automatically — on both iPhone and Android, browser downloads usually go to Files or a Downloads folder first, not your camera roll.
Closing the browser while a large conversion is still running, which can interrupt mobile browsers more aggressively than desktop ones.
Submitting an image without zooming in on the text areas first, especially for scanned documents where legibility problems are easy to miss at a glance.
Convert from whatever you have on hand
Phone, tablet, or computer — the tool works the same way everywhere.
FAQ
Do I need a separate app on iPhone or Android?
No — a browser-based converter works through Safari or Chrome without installing anything extra.
Where do downloaded JPGs go on mobile?
Usually to the Files app on iPhone or the Downloads folder on Android, not directly to your photo library.
My Android file picker cannot find the PDF — what do I do?
Open the file directly in Google Drive or Files by Google, then use Share to send it to your browser instead of relying on the picker.
Is converting a scanned PDF the same as OCR?
No. OCR recognizes and extracts text; PDF to JPG only creates image files that preserve the visual page.
What if my PDF is very large?
Try converting fewer pages at a time, or use a computer with more available memory for the heaviest files.
