A folder of vacation photos is nice. A slideshow with a warm narrated story behind each picture is something people actually watch to the end. The good news: you no longer need a microphone, a quiet room, or a radio voice to add narration. This guide walks through the full workflow — from raw iPhone photos to a polished, voiced slideshow — using free tools at every step.
The Three-Step Workflow
Creating a narrated slideshow breaks down into three stages:
- Prepare the photos — convert iPhone HEIC images into a universally compatible format
- Build the slides — arrange photos in your slideshow or video editor
- Add the voiceover — generate professional narration with AI text-to-speech
Let's go through each step.
Step 1: Convert Your iPhone Photos
iPhone photos are saved in HEIC format, which most slideshow makers and video editors won't accept. Convert them first:
- For individual slides, use our free HEIC to JPG converter — JPG works in every editor
- For a printable companion document or shot list, our HEIC to PDF converter merges up to 20 photos into one file
- Converting a whole album? The batch converter processes 20 files in one click
Everything runs in your browser — photos never leave your device.
Step 2: Build Your Slideshow
With JPGs in hand, assemble the slides in whatever tool you already use — PowerPoint, Google Slides, Canva, CapCut, or iMovie. A few composition tips:
- Aim for 4–6 seconds per photo; longer if the narration for that slide runs longer
- Keep photo orientation consistent — mixing portrait and landscape looks choppy
- Lead with your strongest image, not chronological order
- Write your script before finalizing slide timing, so narration and visuals sync
Step 3: Generate the AI Voiceover
Here's where the magic happens. Instead of recording yourself, paste your script into an AI text-to-speech tool like AnySpeech, which generates studio-quality narration from plain text:
- Write your script: One short paragraph per slide works best
- Pick a voice: AnySpeech offers 100+ AI voices across 50+ languages — from warm storytelling tones to crisp documentary styles
- Adjust pacing: Tune speed and pitch so the narration breathes with your slides
- Download the MP3: Drop the audio track into your slideshow editor and align it with the visuals
💡 Pro Tip
Generate the voiceover slide by slide rather than as one long file. Short audio clips are far easier to re-sync when you reorder slides or change timing later.
Why AI Voiceover Beats Self-Recording
- No equipment: No microphone, pop filter, or soundproofing needed
- Unlimited retakes: Edit the text and regenerate — no re-recording a whole take over one stumble
- Multilingual reach: The same script can be narrated in Spanish, Japanese, or Hindi for international family or audiences
- Consistency: The voice sounds identical whether you generate audio today or add a slide next month
Project Ideas to Try
- Travel recaps: Narrate the story behind each stop on your trip
- Family milestones: Birthday and anniversary retrospectives with a storyteller voice
- Real estate walkthroughs: Property photos with professional listing narration
- Memorial tributes: A dignified narrated remembrance from a lifetime of photos
- Product showcases: Photo-based demos with marketing-style narration

Convert Photos NowFrequently Asked Questions
Why won't my slideshow maker accept iPhone photos?
Most editors don't support Apple's HEIC format. Convert the photos to JPG first and they'll import without issues.
Is AI text-to-speech free?
AnySpeech includes free starting credits, enough to narrate a typical photo slideshow before deciding whether you need a paid plan.
Does the AI voice sound robotic?
Modern AI voices are dramatically better than old-school TTS — natural intonation, pauses, and emotion. Pick a voice that matches your content's mood and most listeners won't guess it's synthetic.
Can I use AI narration in videos I publish?
Check the license of your TTS provider — AnySpeech includes commercial usage rights with paid plans, covering YouTube and client work.
Will converting HEIC to JPG hurt photo quality?
At high quality settings the difference is imperceptible. Our converter lets you choose the quality level, with 90% as a sensible default.
Conclusion
A narrated slideshow used to mean recording gear and editing skills. Today it's three free steps: convert your HEIC photos with our HEIC to JPG tool, arrange them in any editor, and let an AI voice from anyspeech.io tell the story. The result is something your audience will actually press play on — and watch to the end.
