How to Convert JPG to PNG on iPhone

iPhone doesn't have a direct JPG-to-PNG converter in the Photos app, but the built-in Shortcuts app and browser-based tools handle it easily. This guide shows you the most reliable methods for converting JPG photos or images to PNG on iPhone.

Open JPG to PNG Converter

Step-by-step instructions

  1. 1

    Use the Shortcuts app

    Open the Shortcuts app. Tap the + button to create a new shortcut. Add the action 'Get Images from Input'. Add 'Convert Image' and set it to PNG. Add 'Save to Photo Album' or 'Save File'. Save and name the shortcut JPG to PNG. Select the JPG in Photos, tap Share → your shortcut. The PNG is saved to your camera roll or Files.

    Go to converter
  2. 2

    Use an online converter in Safari

    Open Safari and go to formatdrop.com. Tap the image converter, upload your JPG, and download the PNG. The file saves to your Downloads folder in the Files app. Tap and hold → Save to Photos if you want it in your camera roll.

  3. 3

    Use a converter app from the App Store

    Image Converter apps on the App Store (search 'image converter') convert JPG to PNG directly on your iPhone. Open the JPG in the app, select PNG output, and save. Most free apps handle basic conversions without watermarks.

  4. 4

    Verify and use the PNG

    Open the converted PNG in Photos or Files to verify it looks correct. PNG files from iPhone conversions are typically 2–4× larger than the JPG source. Share via AirDrop, iMessage, or Mail. Some apps that require PNG specifically (like certain design apps) will now accept the converted file.

Why convert JPG to PNG?

Design apps, document scanners, and some upload forms on iPhone specifically accept PNG. The built-in Shortcuts app provides a free, permanent solution for JPG-to-PNG conversion without needing third-party apps.

Your files never leave your device

FormatDrop runs the conversion engine entirely inside your browser using WebAssembly. No file upload. No server. Nothing stored. You can verify this by opening DevTools → Network tab and watching: zero upload requests.

Frequently asked questions

Can the iPhone Shortcuts app convert multiple JPGs to PNG at once?
Yes — modify the shortcut to accept multiple inputs. In the shortcut, change the 'Get Images from Input' action to receive from 'Select Photos' and enable 'Select Multiple'. Then the shortcut can convert a batch of selected JPGs to PNG at once.
Does iPhone save photos as JPG or PNG?
iPhone cameras save photos as HEIC (modern iPhones with iOS 11+) or JPG. Screenshots are saved as PNG. When you share photos, iOS often converts HEIC to JPG automatically. For JPG-to-PNG conversion, you need the source to already be a JPG file on your device.
Why is my converted PNG so large?
PNG is a lossless format — it stores every pixel without compression. iPhone JPG photos are typically 2–5 MB. The same image as PNG is 10–20 MB. This is expected. If file size matters more than format, keep the JPG. Only convert to PNG when the PNG format is specifically needed.
