How to convert HEIC to JPG and other formats on iPhone

To convert a file on iPhone, open Lessr, add your photo or video, and choose the format you want — like HEIC to JPG, PNG to JPG, or MP4 to MOV. Lessr makes a new file in the chosen format right on your device, so your original stays as it is and nothing is uploaded.

How to convert a file

Open Lessr and choose Convert.
Add a photo or video from your library or the Files app.
Pick the format you want to convert to, such as JPG, PNG, WebP, HEIC, MP4, or MOV.
Set a quality level, or for videos choose an output resolution, if you want.
Tap Convert, then save the new file to Files or Photos, or share it directly.

Supported formats

Input: Photos: HEIC, JPEG, PNG, WebP. Videos: MP4, MOV.

Convert between any of these — for example HEIC to JPG, PNG to JPG, JPG to PNG, WebP to JPG, or MP4 to MOV.

Output format for videos: MP4 or MOV

When to use Convert

Open iPhone photos on Windows and Android

iPhones save photos as HEIC, which many Windows PCs, Android phones, and websites cannot open. Convert HEIC to JPG so your pictures open and share anywhere.

Upload to sites and forms that reject HEIC

Job portals, government forms, and older web tools often accept only JPG or PNG. Converting first avoids the 'unsupported file' error when you try to upload.

Turn downloaded WebP images into JPG or PNG

Images saved from the web often come as WebP, which some apps and editors will not open. Convert them to JPG or PNG so they drop right in.

Make a video play in the right app

Switch a clip between MP4 and MOV so it opens in the player, editor, or website you need without complaints about the format.

Tips

Converting HEIC to JPG is the fix for photos that 'won't open' on a PC, an Android phone, or a website.
Pick JPG for the widest compatibility, or PNG for a copy with no further quality loss.
If you also want a smaller file, lower the quality level while you convert.

Frequently asked questions

How do I convert HEIC to JPG?

Open Lessr, choose Convert, add your HEIC photo, pick JPG as the output format, and tap Convert. The new JPG saves to Files or Photos, ready to open on any device or website.

Why won't my iPhone photos open on Windows or Android?

iPhones save photos in HEIC, which many PCs, Android phones, and websites don't support. Converting them to JPG with Lessr makes them open everywhere.

Does converting change my original file?

No. Lessr creates a new file in the format you chose and leaves your original exactly as it was.

How many files can I convert for free?

The free version includes 2 conversions per day, one file at a time. Pro removes the daily limit and lets you convert many files in one batch.

Are my files uploaded to a server?

No. Conversion happens entirely on your iPhone or iPad. Lessr makes no network connections and never uploads your files.

Will converting lower my photo's quality?

Converting to PNG keeps every detail. For JPEG, HEIC, and WebP you can set a quality level, so you choose the balance between quality and file size before you save.

Convert runs entirely on your iPhone or iPad — no uploads, no account, no ads.
