A contact sheet shows what a video contains at a glance: the whole clip is sampled into N×M evenly spaced frames and tiled into a single image. It is ideal for cataloguing footage, sharing on forums or cloud drives, skimming long recordings before editing, or checking what is inside a file without playing it. Choose 1–10 columns and 1–12 rows, a sheet width from 1280 to 3840 px, spacing, and a dark or light theme. Every thumbnail gets a timestamp, and the header lists the file name, duration, resolution and frame rate, file size, average bitrate and video/audio codecs — drawn with your browser fonts, so any file name renders correctly. Select several videos to batch-generate sheets as JPG (adjustable quality) or lossless PNG, downloaded together as a ZIP.

## How to use

1. Upload one or more videos
2. Set columns, rows, sheet width, spacing and theme; toggle the header and timestamps
3. Click Create contact sheet, preview it and download the JPG / PNG (a ZIP for several files)

## FAQ

### How are the frames chosen?

The duration is split into N×M equal slots and the middle frame of each slot is used — for a 4×4 grid that is 1/32, 3/32, 5/32… of the way through — so the sheet covers the whole video while skipping the black frames often found at the very start and end. FFmpeg seeks precisely, so results are consistent across formats.

### Why is it slow for some videos?

Each thumbnail is decoded from the nearest keyframe up to its timestamp, so 4K footage or files with long keyframe intervals take longer, and bigger grids (10×12 = 120 frames) take longer still. Try 4×4 or 5×5 first, then go bigger once you like the layout.

### Are my files uploaded to a server?

No. Everything runs locally in your browser via WebAssembly. Files never leave your computer and are discarded when you close the page.

### Do I need to sign up or pay?

No. The site is completely free, requires no account, has no usage limits and adds no watermarks.
