Need help?BMP to 3GP Converter
A BMP is a single still image, and 3GP is a mobile-phone video container — so this is a still-to-video conversion, not a re-encode. The tool wraps your one BMP picture in a short, silent 3GP clip that holds that single frame on screen for a duration you choose. Nothing animates: the output is one image shown for a few seconds. 3GP is a small, dated format built for 3G handsets, so before you commit, it is worth understanding both formats and whether 3GP is really the target you want.
BMP Format at a Glance
| Property | Value |
|---|---|
| Full name | Windows Bitmap / Device-Independent Bitmap (DIB) |
| Created by | Microsoft |
| Type | Raster still image |
| Compression | Usually none (optionally RLE); files are large |
| Bit depth | 1, 2, 4, 8, 16, 24, or 32 bits per pixel |
| Alpha channel | Yes, from the V3 header onward (32-bit) |
| File extension | .bmp, .dib |
| Best for | Lossless Windows-era assets, icons, simple raster editing |
3GP Format at a Glance
| Property | Value |
|---|---|
| Full name | 3GPP file format |
| Defined by | 3rd Generation Partnership Project (3GPP) |
| Based on | ISO base media file format (ISO/IEC 14496-12), the same family as MP4 |
| Video codecs | H.263, MPEG-4 Part 2, H.264/AVC |
| Audio codecs | AMR, AAC (not used here — output is silent) |
| Era | 3G feature phones and early smartphones, early-to-mid 2000s |
| Browser support | Minimal on desktop; MDN lists native playback only on Firefox for Android |
| MIME type | video/3gpp |
How to Convert BMP to 3GP
- Upload Your BMP File: Drag and drop your bitmap, or click "+ Add Files" to pick it from your computer. You can add several BMPs at once.
- Set the Image Duration: Choose how long the still is displayed in the clip — the "Image Duration" dropdown ranges from a single frame up to 10 seconds per image.
- Pick a Background Color and Resolution: Use "Background Color" to fill any area outside your image's aspect ratio, and set a "Preset Resolution" (e.g. 240p or 480p) to match the small frame sizes 3GP was designed for.
- Convert and Download: Click "Convert" to get your 3GP file. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. No sign-up, no watermark.
Should You Use 3GP, MP4, or a Still Image?
| You want… | Better target | Why |
|---|---|---|
| A clip that plays on modern phones, browsers, and editors | BMP to MP4 | MP4 (ISO/IEC 14496-14) plays in every major browser; 3GP does not |
| Compatibility with an old 3G handset or legacy device | 3GP (this page) | 3GP was purpose-built for those devices |
| A smaller, widely-viewable image, not a video | BMP to PNG or BMP to JPG | Keeps it a still, drops the huge uncompressed BMP size |
| An animated clip from several images | BMP to GIF | GIF loops multiple frames; a single-image 3GP does not |
Frequently Asked Questions
Does converting BMP to 3GP create an animated video?
No. A single BMP becomes a single video frame, so the 3GP just shows that one picture for the duration you set. If you upload several BMPs with the "Merge images" option, they play in sequence like a slideshow — but one image on its own does not animate.
Will the 3GP have any sound?
No. This conversion produces a silent clip — there is no audio track because a BMP image carries no audio. The 3GP container can hold AMR or AAC audio in general, but none is added here.
Why does my 3GP look low-resolution compared to the BMP?
3GP was designed for 3G mobile bandwidth, so its codecs (H.263 / MPEG-4 Part 2) and small preset frame sizes are tuned for tiny files, not for the pixel-for-pixel detail an uncompressed BMP can hold. If sharpness matters, convert to MP4 at a higher resolution instead.
Should I use MP4 instead of 3GP?
For almost any modern use, yes. MP4 plays natively in Chrome, Firefox, Safari, and Edge, while MDN lists native 3GP playback only on Firefox for Android — so a 3GP clip may simply not open on a desktop. Choose 3GP only when you specifically need to feed an older 3G-era device.
Why is my BMP so large before conversion?
Most BMP files are stored uncompressed, so every pixel takes full space on disk — a plain photo can run into tens of megabytes. The 3GP output is far smaller because the video codec compresses the frame. If you only need a compact image, BMP to PNG is usually the better move.
Is my file kept private?
Your BMP 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 files are never shared or made public. In our testing, a single 24-bit BMP at a 480p preset produces a 3GP of only a few hundred kilobytes, so uploads stay quick.
