H265 to MP4
Files with the extension .h265 or .265 contain a RAW H.265/HEVC video stream without a container. This means that although the video data is compressed, it lacks an encapsulating format such as MP4, which carries metadata such as frame rate, resolution, timestamps or audio tracks. Without this container, most players and editing programmes cannot handle […]

LRV (Low Resolution Video) files are automatically generated by GoPro cameras and some Insta360 models, and serve as compressed preview videos alongside the actual high-resolution footage. Although technically these are MPEG-4 files with H.264-encoded video, most media players and video editing programmes do not recognise the .LRV file extension and refuse to play them. As […]

EXR files are image files with a very wide range of features and are used primarily in the film industry. EXR was developed starting in 1999 by Industrial Light & Magic (ILM), the studio behind the special effects for Star Wars, Jurassic Park, and many other productions. It was released as open source in 2003 […]

There have been many attempts to replace JPEG: WDP, JXR, JPEG-2000—all of them failed. JPEG XL faced almost the same fate, but in late 2025/early 2026, the tide turned (once again): Google will support JPEG XL in Chrome after all. JXL as the successor to JPEG JPEG XL (file extension .jxl) has arrived to replace […]
Read MoreJXL to WEBP
JXL files cannot yet be used easily on the web in 2026: only Safari displays them natively; whilst Chrome and Firefox have the decoder built in, it is still hidden behind a feature flag. So if you have received or exported a photo in JXL format and want to embed it on a website, share […]

The .vid file extension is not a standardized video format, but it is commonly used by various hardware and software applications for video files. In most cases, a .vid file is simply a standard video (MP4 or AVI) that has been given the .vid file extension. I am not aware of any specific source for […]

LRF stands for Low Resolution File and is a proprietary video format developed by drone and camera manufacturer DJI. When recording video with certain DJI cameras, such as the DJI Osmo Action, and some drones, an associated .lrf file is saved alongside the actual video file in MP4 format. These LRF files serve as so-called […]
Read MoreDDS
DDS stands for DirectDraw Surface and is a file format developed by Microsoft for storing textures and surface data for 3D applications. The format was introduced alongside DirectX 7 to store both compressed and [1]uncompressed textures. The header is directly derived from the DirectDraw 7 structures, and although DirectDraw itself has long been considered a […]

The Core Audio Format (CAF) is a container format developed by Apple for storing and transferring digital audio data. Apple introduced the format in 2005 with Mac OS X 10.4 (Tiger) to overcome the technical limitations of some older formats such as WAV and AIFF. CAF joins a long list of Apple’s own audio formats, […]

XLR files are spreadsheets created using Microsoft Works. XLR files therefore contain typical spreadsheet data such as cells in rows and columns, NUMBERS, formulas, and charts. Unlike XLS and XLSX files, XLR files support significantly fewer features: no macros, no VBA, and usually only one sheet per file. Things used to be a bit simpler […]
