Need help?Convert HEIF to 3GP Online
This tool turns a HEIF photo (the High Efficiency Image File Format that iPhones save by default) into a short 3GP video clip that plays on older 3G-era and basic mobile phones. Because HEIF is a still image and 3GP is the 3GPP mobile video container, the result is a silent clip that holds your single photo on screen for a set duration — it does not animate and it has no audio track. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark.
How to Convert HEIF to 3GP
- Upload Your HEIF File: Drag and drop your
.heifor.heicphoto onto the page, or click "Add Files." You can queue several photos at once. - Set the Image Duration: Use the Duration dropdown to choose how long the still is shown (1/60 of a second up to 10 seconds per frame). This becomes the length of the silent 3GP clip.
- Pick a Background Color and Resolution: Choose a Background Color (default black) to fill any letterboxing, and set Video Resolution to keep the original size or pick a preset — 3GP is a low-resolution format, so smaller presets play more reliably on old handsets.
- Convert and Download: Click "Convert" and download your 3GP file. No sign-up, no watermark.
Should You Convert HEIF to 3GP, MP4, or JPG?
3GP only makes sense if a specific old device or carrier app requires it. For almost any modern phone or social platform, MP4 is the better video target, and if you just want a viewable picture, a plain image format is the right move.
| You want… | Best target | Why |
|---|---|---|
| A photo-as-video clip for an old 3G/feature phone | 3GP (this tool) | Plays on legacy handsets that reject MP4 |
| A photo-as-video clip for any modern phone or social media | MP4 (convert HEIF to MP4) | H.264/MP4 plays everywhere; far higher resolution ceiling |
| A normal, viewable still image (no video) | JPG (convert HEIF to JPG) | Universally supported photo format; HEIF only opens natively on Safari 17+ |

Frequently Asked Questions
Why is my 3GP clip silent?
A HEIF file is a still photograph — it contains no sound. Converting one image to a 3GP video produces a clip that simply displays that photo for the duration you set, with no audio track. If you need sound, you would have to add an audio file separately after conversion using a video editor.
How long will the 3GP video be?
The clip length equals the Image Duration you choose, from a fraction of a second up to 10 seconds per frame. If you upload several photos and pick "Merge images," each photo is shown for that duration in sequence, so the total runtime is the duration multiplied by the number of images.
Should I use 3GP or MP4 to share a photo as a video?
For anything other than a genuinely old handset, choose MP4. 3GP was designed for 3G-era phones with tight bandwidth and small screens, so it caps quality at low resolutions. MP4 with H.264 plays on essentially every modern phone, browser, and social platform at much higher quality — use convert HEIF to MP4 instead.
Why can't I just open the HEIF file directly?
HEIF/HEIC is an HEVC-based image format with limited native support — among browsers only Safari 17 and later decodes it, and Chrome, Firefox, and Edge do not. That is the main reason people convert HEIF at all: to a video format like 3GP or MP4 for playback, or to JPG for a universally viewable picture.
What resolution should I pick for an old phone?
In our testing, legacy 3GP-only handsets play most reliably at small frame sizes such as QCIF or CIF, so if your goal is true feature-phone compatibility, choose a smaller resolution preset rather than keeping a full-size iPhone photo. Modern devices have no such limit, in which case MP4 is the better choice anyway.
Is my photo kept private?
Yes. Your HEIF file is uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and your files are never shared or made public.
