XMP sidecar
XMP
Full
Open the XMP sidecar (.xmp) that Lightroom, Adobe Camera Raw and darktable write next to a raw photo to keep its edits while the raw stays untouched, and see the develop recipe visualised: the tone curve drawn as a real curve, the Basic-panel sliders (exposure, contrast, highlights, shadows, whites, blacks, texture, clarity, dehaze, vibrance and saturation) as bipolar bars, the HSL colour mixer, and the crop rectangle. Reads the editor and process version, the paired raw file, white balance, star rating and colour label, the camera and lens metadata copied from the raw, and the catalog title, keywords and copyright - all in the browser. A darktable sidecar lists the processing modules its edit switches on.

Video
MP4 MOV AVI MKV WebM WMV FLV 3GP 3G2 MPG MPEG MTS M2TS TS VOB OGV H264 264 AVC H265 265 HEVC
Full
Read the container, codec, resolution, and frame rate of MP4, MOV, MKV, AVI, and WebM video, step through frames, and extract the audio track. Raw H.264/H.265 elementary streams (.h264/.265) are remuxed to MP4 in-browser so they play too, as are AVCHD camcorder files (.mts/.m2ts) - the video is copied and the audio transcoded to AAC. Sony cameras (Alpha, FX, RX) that embed a gyro / accelerometer "rtmd" timed-metadata track have that inertial data decoded and plotted - the same gyroscope and accelerometer samples Gyroflow and Catalyst Browse use to stabilise footage - alongside the ISO, white balance and capture time.

Colour LUT
CUBE LOOK
Full
Open colour LUTs (.cube - the Adobe/Iridas/Resolve 3D and 1D look-up tables) and Adobe SpeedGrade / Iridas looks (.look) and see exactly what they do: the neutral tone-response curve that reveals the contrast and colour cast, a before/after of a hue x brightness chart and memory colours (skin, sky, foliage) pushed through the LUT, and an interactive 3D scatter of the colour cube it defines. A .look is read as the SpeedGrade grade stack (basic correction, tints, wheels, curves, secondaries, vignette and more) with the baked 3D LUT it carries visualised the same way. Reads the title, grid size, input domain and extended (HDR / scene-linear) output range, all in the browser. The same .cube extension that Gaussian uses for volumetric DFT data is detected and identified separately.
Editing timeline
EDL FCPXML OTIO
Full
Visualise editing timelines exported from Premiere Pro, Final Cut Pro, DaVinci Resolve and Avid: CMX3600 EDL, Final Cut Pro FCPXML and OpenTimelineIO (OTIO). Renders the tracks with clip blocks positioned by timecode, plus durations, clip names and frame rate.
After Effects
AEP AET
Full
Open Adobe After Effects projects (.aep) and templates (.aet) in the browser. Analyser walks the RIFX chunk tree to rebuild every composition timeline - each layer drawn as a bar positioned by its in and out point, colour-coded by footage, pre-comp, audio and shape, with 3D layers marked - and reads each comp's dimensions, frame rate, duration and layer count. The After Effects version that created and last saved the project (and the create/modify dates) are read from the embedded XMP metadata, alongside the list of footage and source files the project references.
Gyro log
GCSV
Full
Open Gyroflow .gcsv IMU logs - the gyroscope and accelerometer telemetry used to stabilise footage. Analyser applies the file's own scale factors and plots the three-axis gyroscope (deg/s) and accelerometer (g) against time on a zoomable timeline you can hover to read off values.
Per-format guides: .GCSV
Premiere Pro
PRPROJ PREL
Full
Open Adobe Premiere Pro (.prproj) and Premiere Elements (.prel) projects in the browser. Analyser inflates the gzip-compressed PremiereData XML and walks the sequence, track and clip objects to rebuild every timeline - each clip drawn as a bar positioned by its in and out point across stacked video and audio tracks, just like the Premiere editor - reading each sequence's resolution, frame rate, duration, track and clip counts, plus the project version, media-item count and the names of the clips the timelines reference.
DaVinci Resolve
DRP DRT
Full
Open Blackmagic DaVinci Resolve project (.drp) and timeline (.drt) exports in the browser. A .drp is a ZIP of database XML; Analyser unzips it and walks the SeqContainer track and clip objects to rebuild every timeline - each clip drawn as a bar positioned by its Start and Duration across stacked video and audio tracks, just like the Resolve edit page - showing source filenames, paths, frame rates and timecode, plus the project name, Resolve version, the media pool bins and the source media the timelines reference. Titles, generators and transitions are colour-coded.
VEGAS Pro
VEG VF
Partial
Open Sony / MAGIX VEGAS Pro (.veg) and VEGAS Movie Studio (.vf) projects in the browser. A .veg is a Sonic Foundry "RIFF GUID" container; Analyser reads the VEGAS version, the project summary (author, copyright, contact), every media generator and video FX used by its plugin id and friendly name (Titles & Text, Solid Color, Cookie Cutter and more), the actual title and text content decoded from the embedded RTF, and the source media and template file paths the project references.
Subtitles
SRT VTT ASS SSA SUB
Full
Parse subtitle cues and timing from SubRip (SRT), WebVTT, ASS/SSA, MicroDVD and SubViewer (.sub): cue count, on-screen time, and a full timed cue list. MicroDVD frame timings are converted to time using the declared or assumed frame rate; binary VobSub .sub image subtitles are identified.

AI
Partial
Open Adobe Illustrator artwork (.ai) in the browser. Modern Illustrator files (version 9 and later) are PDF-compatible, so Analyser renders the artwork page by page with pdf.js - the vector art, text and embedded images - and reads the document metadata. Older EPS/PostScript-based .ai files are identified from their header.
Per-format guides: .AI
Photoshop
PSD PSB
Partial
Open Adobe Photoshop documents (PSD and PSB) in the browser: the flattened composite image Photoshop bakes in is shown, plus the full layer tree with each layer name, blend mode, opacity, visibility and a per-layer thumbnail. Reads the canvas dimensions, colour mode and bit depth. Files saved without Maximize Compatibility have no composite, so their layers are shown instead.
Raster art

3D model
STL OBJ PLY OFF STEP STP IGES IGS BREP 3MF AMF glTF GLB MTL
Full
View STL, OBJ, PLY, OFF, STEP, IGES, BREP, 3MF, AMF and glTF/GLB models in an interactive WebGL viewer with orbit, orthographic or perspective projection, a wireframe topology overlay, an orientation cube, triangle count, bounding box, surface area and volume. glTF 2.0 and binary GLB scenes are parsed natively - the node graph is flattened, mesh geometry shown, and the authoring tool, version and mesh/material/animation counts read. STEP/IGES/BREP are tessellated with OpenCASCADE and STEP shows its originating CAD system, version and AP203/214/242 protocol; 3MF and AMF let you inspect each model and assembly on the build plate individually. Wavefront material libraries (MTL) are broken out into each material with its colours, shininess, opacity and the texture files it references.

Fusion 360
F3D F3Z
Partial
Open an Autodesk Fusion 360 design (.f3d) or archive (.f3z) and read what it holds: the document type (part, assembly, drawing or sheet metal), the Fusion document version, the number of solid bodies and embedded appearance assets, and the thumbnail Fusion rendered into the file - shown as the model. The editable geometry is stored as Autodesk ShapeManager BREP, a proprietary format that cannot be rebuilt in the browser, so export to STL, OBJ, STEP or 3MF for the full 3D viewer.
SolidWorks
SLDPRT SLDASM SLDDRW
Partial
Open a SolidWorks part (.sldprt), assembly (.sldasm) or drawing (.slddrw). Older (pre-2015) files are OLE2 documents: Analyser reads the saved preview thumbnail and the document metadata (title, author, who last saved it and when). Files saved by SolidWorks 2015 or later are encrypted by Dassault Systemes, so they are identified but their contents cannot be read outside SolidWorks - in either case the editable Parasolid geometry stays proprietary, so export to STEP, STL or 3MF for the full 3D viewer.
G-code
GCODE GCO G NC NGC TAP CNC
Full
Reconstruct and visualise the printed (or machined) object straight from G-code: every extruded move is drawn as a line in an interactive WebGL viewer, height-coloured and Z-up, with a build-height scrubber to peel the print back layer by layer. Works universally across slicers (PrusaSlicer, SuperSlicer, OrcaSlicer, Cura, ideaMaker, Bambu Studio, Simplify3D) and CNC / laser CAM, handling absolute and relative moves, inch and millimetre units, and G2/G3 arcs; travel moves are separated out. Reads the slicer or CAM tool, object size, layer count and height, filament or cut-path length, feedrate range, and nozzle/bed temperatures.

Diagrams
DRAWIO DXF DWG DWT
Full
Render 2D vector diagrams and CAD drawings to a preview: draw.io / diagrams.net (DRAWIO) files - decoding the mxGraph model, inline or compressed - AutoCAD DXF drawings (parsing the ASCII ENTITIES section), and binary AutoCAD DWG/DWT drawings, parsed by LibreDWG (WebAssembly) into their entities and rendered to an SVG, with an entity and layer breakdown.
Altium (EDA)
SchDoc SchLib PcbDoc PcbLib PrjPcb EPW
Full
Open Altium Designer schematics, circuit boards and projects in the browser. Analyser reads the OLE compound-file streams of schematic documents (.SchDoc) and symbol libraries (.SchLib), and PCB documents (.PcbDoc) and footprint libraries (.PcbLib), and rebuilds the geometry as an interactive vector view: schematic symbols, wires and pins, or the board outline, copper, pads, tracks and arcs - with pan, zoom and per-layer visibility toggles. It surfaces the component part numbers, datasheet and supplier links, the pad table and the layers used, reads the project manifest (.PrjPcb) with its member documents, and decodes the SamacSys ECAD Model wrapper (.epw). Nothing is uploaded.

KiCad (EDA)
kicad_sch kicad_pcb kicad_sym kicad_mod kicad_pro kicad_prl
Full
Open KiCad schematics, circuit boards, footprints and projects in the browser. Analyser parses the S-expression documents - schematics (.kicad_sch), boards (.kicad_pcb), symbol libraries (.kicad_sym) and footprint modules (.kicad_mod), including the "-bak" backups - and rebuilds the geometry as an interactive vector view: schematic symbols, wires, junctions and labels, or the board outline, copper tracks, pads, vias, zones and silkscreen, with pan, zoom and per-layer visibility toggles. It reads the project settings (.kicad_pro / .kicad_prl JSON) with its net classes, the library tables, the footprint cache and the ngspice simulation workbook (.wbk), and plots the SPICE simulation waveforms (.raw) from KiCad/ngspice or LTspice - decoding the analysis type, variables and samples to chart the traces or tabulate an operating point. Dropping a whole project folder opens every document together as one design with a combined bill of materials that cross-probes each part to its symbol on the schematic and its footprint on the board. Nothing is uploaded.

IPC netlist (EDA)
IPC
Full
Open IPC-D-356A bare-board fabrication and electrical-test netlists (.ipc) exported by KiCad, Altium and other PCB tools. Analyser parses the fixed-column feature records - the net each test point belongs to, the component reference and pin, the pad or via geometry and its X/Y position - and rebuilds the full net-to-pin connectivity, summarises the nets, components and pad/via mix, and draws a fabrication map of every test point coloured by net.

Disk images
ISO IMG IMA DSK IMC ADI VHD VHDX VMDK QCOW2 VDI
ID
Open raw disk images (IMG, IMA, DSK) like a folder - Analyser mounts the FAT12/16/32 filesystem, whether a bare SD card / USB / floppy image or an MBR-partitioned disk, and lists every file in a browsable tree and treemap so you can click any one to analyse it, reading the volume label, cluster size and free space along the way; it also carves every image out of the raw sectors, recovering deleted and orphaned photos the directory no longer lists. It identifies virtual-machine and optical images (VHD/VHDX Hyper-V, VMDK VMware, QCOW2 QEMU, VDI VirtualBox, ISO) and shows the partition table; non-FAT filesystems (ISO 9660, ext2/3/4, NTFS, exFAT) are identified but not yet browsed. Compressed backups (IMC - Runtime Software / GetDataBack; ADI - Active@ Disk Image / AOMEI Backupper) are identified with their label and details; convert them to a raw .img in the tool that made them to browse and carve them.
