Fix iPhone-to-Windows Photo Sharing: What You'll Achieve in 30 Minutes

If you shoot on an iPhone and your client on Windows opens the files and gets nothing but grief, this guide walks you through practical, tested ways to make your photos accessible without degrading quality or turning every delivery into a tech support ticket. In one session you’ll end up able to:

Send fully compatible JPEGs and MP4s that open on older Windows machines. Preserve original HEIC/HEIF or HEVC files for archiving and retouching. Automate batch conversions so you never have to hand-convert 200 files again. Keep color and metadata intact when it matters and reduce file size when it doesn’t.

Before You Start: Required Apps and Files for Sending iPhone Photos to Windows Clients

Gather these tools. Think of them as your toolbox - you can use one or many depending on the client’s setup.

macOS with Photos or Preview (makes converting trivial). Windows 10/11 with Microsoft Store access (HEIF Image Extensions, HEVC extension optional). ImageMagick or libheif tools (for batch work on macOS, Windows, Linux). ffmpeg for video conversions.

If the client is stuck on Windows 7 or older corporate builds with no admin rights, assume they cannot install anything. In that case, prepare universal files up front - JPEG for images, MP4 (H.264) for video.

Your Complete iPhone-to-Windows Transfer Roadmap: 10 Steps from Shoot to Client Delivery

Follow these practical steps. Think of this as your checklist for every delivery.

Decide what the client actually needs

Do they need full-resolution files for printing or quick previews for approval? For print, supply full-res JPG or TIFF plus the original HEIC/RAW. For approval, 2048 px long side JPEG at quality 90 is usually perfect and small enough to email or upload fast.

Shoot settings - stop the problem at source

On iPhone go to Settings > Camera > Formats. If 100% compatibility is your default, choose Most Compatible to get JPEG and H.264 video. If you want smaller files and better dynamic range, keep High Efficiency (HEIC/HEVC) but prepare to convert later.

Export method - automatic conversion when sharing

When you share from Photos app: select images, tap Share, then tap Options at the top of the Share sheet. If you’re emailing or sending to another device, toggle “Transfer to Mac or PC” to Automatic. On iCloud.com, downloaded images will typically be converted to JPEG automatically, which is useful if your client can use the browser.

Provide two-file delivery: Compatibility + Originals

Zip this for each job:

FILENAME_original.heic (or .dng for RAW) FILENAME_client.jpg (sRGB, long side 2048 px, quality 90)

This covers both archival needs and immediate usability. It’s the photography equivalent of sending the cake and the recipe.

Quick convert on iPhone - Shortcuts to the rescue

Create or download a Shortcuts action that:

Takes selected photos Converts HEIC/HEVC to JPEG/MP4 at chosen resolution Saves to Files or offers a share sheet

Example: set output JPEG quality to 90, resize to 2048 px long side. Run on batch of 50 photos in about 90 seconds for modern iPhones.

Batch convert on desktop - image commands you can actually use

If you’re on macOS, Preview or Photos can batch export. For precise control use ImageMagick:

CommandPurpose magick mogrify -format jpg -quality 95 -path output/ *.heic Batch convert HEIC to JPEG at quality 95 heif-convert input.heic output.jpg Simple libheif conversion (fast, keeps metadata)

For Windows, install ImageMagick or use WSL and run the same commands. Always run a test on 3 files to verify color and metadata.

Convert video with ffmpeg

HEVC MOV from iPhone to H.264 MP4 - compatible and still high quality:

CommandExample ffmpeg -i input.mov -c:v libx264 -crf 18 -preset medium -c:a aac -b:a 192k output.mp4 Transcodes HEVC to H.264. CRF 18 gives near-transparent quality.

Preserve metadata and color profiles

HEIC often holds Display P3 color. Convert to sRGB for older Windows apps to avoid blown-out colors. Use ImageMagick flag -colorspace sRGB or use ExifTool to check and copy tags:

CommandPurpose magick input.heic -colorspace sRGB -quality 92 output.jpg Convert color profile to sRGB during conversion exiftool -tagsfromfile in.heic -all:all out.jpg Copy metadata from HEIC to JPEG

Create a delivery package and test on a Windows machine

Zip the client-ready JPGs and include originals in a folder. Upload to Dropbox, Google Drive or WeTransfer. Download the zip and open a few files on a Windows machine or VM to confirm compatibility before sending the link.

Windows HEIC issue

Offer the client one-click fixes

If the client can install one thing, tell them to add Microsoft Store - HEIF Image Extensions and, for videos, HEVC Video Extensions. Tell them the HEVC extension sometimes costs about $0.99. If they can’t install anything, you keep converting on your side.

Avoid These 7 Photo Transfer Mistakes That Break Client Deliverables

Here are the usual traps, and how to sidestep them without a CPR class for file formats.

Sending HEIC only to a Windows 7 user: They will not open the files. Solution - convert to JPG on your side. Delivering HEIC/HEVC without checking color space: Colors look wrong on sRGB-only apps. Convert to sRGB for client-facing files. Stripping metadata accidentally: Some converters drop EXIF and copyright. Use ExifTool to copy tags when metadata matters. Overcompressing JPEGs: Quality 70 is fine for social, but not for prints. Use quality 90-95 for print delivery. Sending uncompressed TIFFs when not needed: File sizes balloon. Save TIFF only for editing masters or print-ready deliverables where the client requests it. Assuming cloud previews equal downloads: Some services show a preview but the download is still HEIC. Verify by downloading on a Windows machine. Forgetting filenames: Odd characters or long paths break batch scripts. Keep filenames simple: Project_Client_001.jpg

Pro Photo Workflow Strategies: Advanced Color, Metadata, and Batch Conversion Tactics

Ready to act like you’ve been doing this for years? Use these techniques to automate, preserve quality and reduce time spent on low-value conversions.

Deliver two catalogs - master and client

Keep a master folder with HEIC/RAW and an export folder with client-ready files. Use a naming convention so you can find originals fast: IMG_1234_master.heic and IMG_1234_client.jpg.

Automate with Shortcuts plus a cloud upload

Create a shortcut that converts selected items to JPEG, renames them with suffix _client, zips the folder, and uploads to your preferred cloud. Trigger it from Share sheet and you’re done in one tap.

Batch scripting for big jobs

On macOS or WSL, run a script that:

That saves hours on shoots with 1,000+ images.

Deliver web-optimized jpegs and separate prints

Create two export sizes: web (2048 px long side, quality 85) and print (full-res, quality 95). Label them so clients don’t confuse the two.

Color proofing for critical work

If you and the client are doing color-critical work, export a soft-proofed JPEG using the client’s target profile, and include an explanation: “Open in Photoshop or use sRGB preview.” Include a flattened TIFF only if requested.

When Transfers Fail: Fixing Common iPhone-to-Windows Compatibility Errors

Here are quick fixes for the “client can’t open the files” calls you dread.

Client says “I get a blank icon or unsupported file”

Ask for OS version. If Windows 10/11, tell them to install HEIF Image Extensions from Microsoft Store. If they can’t install, resend as JPEG. Quick wins: convert 3 files and email one to confirm.

Colors look washed or too saturated

Common cause - Display P3 vs sRGB. Convert exports to sRGB. Test by opening the JPEG in a standard browser; if it looks right there it’s probably fine.

Metadata appears missing in client's system

Some converters strip IPTC or copyright. Use exiftool to copy tags explicitly. Example command:

Video won't play because of codec

Convert to H.264 MP4. Use ffmpeg with -crf 18 for high quality. If the client is on slow internet, also provide a 720p preview file using -crf 23.

Client wants originals but only has browser access

Upload the original HEICs and share a zipped folder via WeTransfer or Dropbox. If they complain about opening, include a short “how to” with links to HEIF extensions or recommend VLC for video and XnView for images.

One last metaphor before you go: think of HEIC/HEVC as a new, efficient shipping container that saves space but needs the right port to unload. Your job is to either ship in a universally unloadable crate (JPEG/MP4) or hand the client the right crane (HEIF/HEVC extensions). Do both when it matters - small JPGs for instant use, originals for future edits.

Run the simple checklist before every delivery: check client OS, decide required format, convert and proof on Windows, package originals. Do that and you will stop getting emails that begin, “I can’t open your files.” If you want, I can generate a Shortcuts script or shell script tailored to your specific exports - tell me whether you use macOS, Windows, or do everything on the phone and I’ll write it out.
