Convert 3GP to MP4 — memories from your old phone, watchable today

                    
3GP was the video format of early camera phones: Nokia, Sony Ericsson, Motorola. Those little clips hold birthdays, concerts and family moments — but modern players often refuse them, or play them without sound. Klipa's 3GP to MP4 converter re-encodes them into standard MP4 that plays everywhere, keeping the original picture untouched.

                

                

                    

                        
No software, no cables: everything happens in your browser. After converting, compress the files for a family group chat, or gather them in one place and convert other old formats too.

How to convert 3GP to MP4

                

                    
Step 1
Upload your 3GP file
Drag and drop the videos from your old phone — Nokia, Motorola, Sony Ericsson memories filmed in the 2000s. Small files convert in seconds.

Step 3
Save your universal MP4
Your video now plays on any modern phone, computer or TV, and shares cleanly on WhatsApp or by email. Compress it if needed, or trim the best moment.

3GP to MP4 — FAQ

                

                    
Is the 3GP to MP4 conversion free?
Your first try is free, without signing up.
Will the quality improve?
Honestly: no. 3GP videos were filmed at low resolution and conversion cannot invent missing detail. What it does is make the file playable everywhere, exactly as it was filmed.
Why does my 3GP play without sound?
Old 3GP files use AMR audio, which many modern players don't support. We convert the sound to AAC, so both picture and audio play everywhere.
Is there a size or length limit?
Pro accepts files up to 2 GB.
Can I convert many small clips?
Yes, one after the other.
Do 3G2 files work too?
3G2 (the CDMA variant of 3GP) usually converts fine as well — upload it and the tool will tell you immediately if the file can't be read.
Is my file kept on your servers?
No. Files are deleted automatically after processing.
