How do I make a photo slideshow video with music for free without a watermark?

Open AnyTool's Video Slideshow Maker, drop in your photos, add a music track, and choose transitions, Ken Burns motion and an aspect ratio (16:9, 9:16 or 1:1). It builds a real MP4 (H.264/AAC) in your browser — faster than real time — with transitions optionally beat-synced to the music. Your photos and music never leave your device, and there is no watermark or sign-up.

  • Photos + music to a real MP4 (H.264/AAC)
  • Beat-synced transitions, Ken Burns motion, live preview
  • Vertical 9:16, square 1:1 and 16:9 for any platform
  • 100% in your browser — no watermark, no upload, no sign-up

What is

Photo slideshow video

A slideshow video turns a set of photos into a single video, showing each image for a duration with transitions, optional pan/zoom (Ken Burns) motion and a music track. A browser-based maker renders the frames to MP4 locally (e.g. via WebCodecs) so the photos are never uploaded.

Detailed Explanation

Methodology

How the Slideshow Maker Works

AnyTool builds a photo slideshow video entirely in the browser. Images are decoded with createImageBitmap and drawn deterministically onto a canvas per frame, applying Ken Burns pan/zoom and true transitions (crossfade, slide, zoom, wipe). A music track is decoded with the Web Audio API; its tempo is detected so transitions can snap to the beat. Frames are encoded with WebCodecs VideoEncoder (H.264) and the audio with AAC, muxed into a real MP4 by a bundled muxer — faster than real time — with a MediaRecorder WebM fallback where WebCodecs is unavailable. A live preview canvas re-renders instantly on any change, and 16:9, 9:16 and 1:1 aspect ratios are supported.

  • Runs client-side — photos and music are never uploaded
  • Ken Burns motion + real transitions, beat-synced to music
  • Real MP4 (H.264/AAC) via WebCodecs, faster than real time
  • Live WYSIWYG preview; WebM fallback where needed
  • 16:9, 9:16 and 1:1 aspect ratios
  • No backend, no watermark, no sign-up
Privacy & Security

Privacy vs Cloud Slideshow Makers

popular design apps, online video editors, Animoto and Clideo upload your photos and music to their cloud and watermark or cap the free tier; Animoto even withholds the download on free. AnyTool renders on the device, so personal photos and music never leave the browser, the output is watermark-free, and it works offline after the first load.
