HEVC / H.265 video converter

HEVC to MP4 Converter

Convert an HEVC or H.265 video to a more compatible H.264 MP4 directly in your browser. Keep the video and available audio without uploading the source file.

The video stays in your browser. It is not uploaded to a server.

H.264 video with optional AAC audio
MP4 output for broader compatibility
Private browser processing

Upload an HEVC or H.265 video

Choose one or more videos. Each file is converted locally, one at a time.

MP4, MOV, M4V, MKV, AVI, and WebM

Conversion queue

Videos are converted one at a time. A failed file does not stop the remaining queue.

How it works

Convert HEVC to MP4 in three steps

The converter uses a focused workflow instead of exposing video encoding settings that most compatibility fixes do not need.

Choose the HEVC or H.265 video stored on your device.

Start the conversion and keep this page open while the browser creates an H.264 MP4.

Preview the converted MP4, then download it or open it in Video to GIF.

What changes when HEVC becomes MP4

HEVC, H.264, and MP4 describe different parts of a video file. Understanding the difference helps explain why renaming a file does not fix compatibility.

HEVC, H.265, and H265 are the source video codec

HEVC and H.265 are two names for the same video compression standard. H265 is a common spelling without the dot in searches, filenames, software settings, and device specifications. The codec can store high-quality video efficiently, but some browsers, upload forms, and editors cannot decode it.

H.264, also written as H264, is the output video codec

The converter decodes the source and re-encodes the picture as H.264/AVC with a broadly supported pixel format. H264 is a common spelling for the same codec in searches, filenames, and software settings. This is a real conversion, not a file-extension change.

MP4 is the output container

MP4 holds the converted video and its audio track. A file can already end in .mp4 and still use HEVC internally, which is why the original MP4 may fail while the converted MP4 works.

Audio is kept when the source has it

When an input audio track is available, it is converted to AAC and included in the MP4. Videos without an audio track remain silent without causing the conversion to fail.

Common sources

When an HEVC to MP4 conversion helps

HEVC is common on recent phones and cameras, while many browser workflows still expect H.264 MP4.

iPhone, iPad, and Samsung videos

Convert High Efficiency recordings when a website or editor cannot preview the original MOV or MP4 file.

GoPro, DJI, and camera footage

Prepare H.265 clips for browser tools and editing workflows that accept H.264 more reliably.

Unsupported video uploads

Create a compatible copy when an upload form reports an unsupported codec even though the filename already ends in MP4.

Video to GIF preparation

Convert a video the GIF editor cannot decode, then continue with trimming, annotations, and GIF export.

Before converting

Quality, size, and browser limits

Video conversion is heavier than renaming or copying a file, so the result depends on the source and the device doing the work.

File size may increase

HEVC is efficient. An H.264 copy can be larger even when it is easier for other software to open.

Re-encoding can change quality

The video is re-encoded for compatibility, so the output is not a lossless copy of the HEVC stream.

Large videos take longer

Long, high-resolution, or high-frame-rate videos require more memory and processing time in the browser.

Not every source can be decoded

Damaged files, protected media, or codecs outside the converter build may still fail and need a desktop video tool.

Continue with the converted video

Turn the compatible MP4 into a GIF, or explore other GIF and video tools after the HEVC conversion is complete.

Create GIFs

Video to GIF

Turn videos into GIFs, then add text, images, arrows, emoji, shapes, and mosaic in the same browser editor.

Video export

GIF to Video

Convert an animated GIF to MP4, WebM, or MOV and set a target video length locally in your browser.

FAQ

Questions about HEVC to MP4 conversion

Practical answers about codecs, sound, quality, privacy, and browser compatibility.

Are HEVC and H.265 the same thing?

Yes. HEVC is the common name and H.265 is the corresponding video coding standard. Both labels usually refer to the same source codec.

Is H265 the same as H.265?

Yes. H265 and H.265 refer to the same video codec. H.265 is the standard written form, while H265 is common in searches, filenames, software settings, and device specifications.

Is MP4 the same as H.264?

No. MP4 is a container, while H.264 is a video codec stored inside a container. An MP4 file can contain HEVC, H.264, or another codec.

Is H264 the same as H.264?

Yes. H264 and H.264 refer to the same video codec. H.264 is the standard written form, while H264 is common in searches, filenames, software settings, and device specifications.

Can I convert HEVC by renaming the file to .mp4?

No. Renaming changes only the filename. This converter decodes the HEVC stream and creates a new H.264 video inside an MP4 container.

Does the converted MP4 keep audio?

Yes, when the source contains a readable audio track. The audio is converted to AAC for MP4 compatibility. A source without audio produces a silent MP4.

Will the converted file be larger?

It can be. HEVC often stores similar visual quality more efficiently than H.264, so a more compatible H.264 version may use more space.

Does conversion reduce video quality?

Re-encoding is not lossless and can change fine detail. The converter uses a balanced quality setting intended for compatibility without making the interface complicated.

Is the original video uploaded?

No. The video is read, converted, previewed, and stored locally in this browser.

Can I use the converted MP4 for Video to GIF?

Yes. After conversion, choose Video to GIF to continue editing the local H.264 MP4 without uploading it again.
