How do I turn a long video into Reels with captions and thumbnails for free?

Open AnyTool's YouTube-to-Reels Publishing Pack, drop in a long video, and it detects highlight clips, reframes each to vertical 9:16, burns captions (self-hosted Whisper), makes a per-clip thumbnail and writes ready-to-paste title/description/hashtags — then bundles everything into one ZIP. Everything runs in your browser: no upload, no watermark, no sign-up and no caps.

  • Long video → multiple vertical 9:16 MP4 clips
  • Burned-in captions + per-clip thumbnail + social copy
  • One downloadable ZIP publishing pack
  • 100% in your browser — no upload, no watermark, no sign-up

What is

Video repurposing pack

A repurposing or publishing pack converts one long video into several short vertical clips ready to post — each reframed to 9:16, captioned, given a thumbnail and paired with a title, description and hashtags — bundled together so a creator can publish to Shorts, Reels and TikTok quickly.

Frequently Asked Questions

No — detection, reframing, captioning and packaging all run in your browser.

Unlike OpusClip, Klap, AI clip tools and Submagic which upload to the cloud, AnyTool keeps the whole video on your device.

No watermark, no sign-up, and no length, export-count or clip-expiry caps — and clips are 1080p.

Many cloud repurposers watermark free clips, cap minutes or expire them; AnyTool does none of that.

Each clip's vertical MP4, a 9:16 thumbnail, an SRT and a text file with title, description and hashtags, plus a master index.

It is a complete posting kit you can upload straight to Shorts, Reels or TikTok.

Detailed Explanation

Methodology

How the YouTube-to-Reels Publishing Pack Works

AnyTool turns one long video into a publishing pack entirely in the browser. It decodes the audio to detect highlight clips (silence/scene boundaries, ranked by energy), reframes each clip to vertical 9:16 with crop or blur-pad, and encodes real H.264/AAC MP4s at 1080p with a self-hosted single-threaded ffmpeg engine. It optionally transcribes once with a self-hosted Whisper model and burns per-clip captions, grabs a representative 9:16 thumbnail per clip, and generates a title, description and hashtags. Everything is bundled into one ZIP with JSZip — no server, no CDN.

  • Runs client-side — the video is never uploaded
  • Smart clip detection + auto 9:16 reframe (crop or blur-pad)
  • Real 1080p H.264/AAC MP4 clips, not previews
  • Optional per-clip caption burn (self-hosted Whisper)
  • Per-clip thumbnail + title/description/hashtags
  • One ZIP publishing pack — no watermark, no sign-up, no caps
Privacy & Security

Privacy vs Cloud Repurposers

OpusClip, Klap, AI clip tools, Submagic and Quso upload your video to the cloud, watermark free clips, cap minutes or exports and expire clips. AnyTool detects, reframes, captions and packages on the device, so the video never leaves the browser, with 1080p clips, no watermark and no caps, and it works offline after the first load.
