Convert WMV to MP4 — your Windows-era videos, playable everywhere

                    
WMV (Windows Media Video) was everywhere in the 2000s: Movie Maker exports, camcorder software, corporate presentations. Today, phones and Macs often refuse to open it. Klipa's WMV to MP4 converter re-encodes those files into standard MP4 (H.264 + AAC) — the format that plays on every device made this decade.

                

                

                    

                        
Everything happens online: no codec packs, no desktop software from a dubious download site. Once converted, shrink the file for messaging, trim the good part, or convert other formats with the main converter.

How to convert WMV to MP4

                

                    
Step 1
Upload your WMV file
Drag and drop your WMV video — old family footage, Movie Maker projects, corporate archives from the Windows era. Large files are accepted.


Step 2
The conversion runs in the cloud
Our server re-encodes the Windows Media stream to H.264 + AAC, the combination every modern device understands. You don't install anything and your computer does none of the work.


Step 3
Save your universal MP4
Your video now plays on iPhone, Android, Mac, smart TVs and in every editor. Compress it to share by email, or add subtitles before publishing.

Escape the Windows-only trap

                        
WMV was built for Windows Media Player. MP4 plays on every phone, tablet, TV and operating system.

                    

                    

                        
                        
Rescue old archives

                        
Family videos and Movie Maker projects from the 2000s become watchable and shareable again.

                    

                    

                        
                        
Ready for editing

                        
Modern editors handle MP4 far better than WMV. Convert first, edit without headaches after.

                    

                    

                        
                        
Clean, no watermark

                        
The converter returns your own video, full length, without any logo stamped on it, whatever your plan.

WMV to MP4 — FAQ

                

                    
Is the WMV to MP4 conversion free?
Your first try is free, without an account.
Will I lose quality?
WMV must be re-encoded (its codec isn't MP4-compatible), but we use quality settings where the difference is not visible in normal viewing. The output will never look worse than the source.
Why won't my WMV play on my phone or Mac?
WMV uses Microsoft's Windows Media codecs, which most non-Windows devices never supported. Converting to MP4 (H.264) solves it permanently.
Is there a size or length limit?
Files can be up to 2 GB. Pro and Studio support videos up to 2 hours.
Does the sound stay in sync?
Yes. The audio track is converted along with the video in the same pass, so synchronization is preserved.
Can I convert MP4 back to WMV?
No — we deliberately target modern formats (MP4, MOV, WebM, MKV, AVI). There is no good reason to produce new WMV files today.
Is my file kept on your servers?
No. Files are deleted automatically after processing.
