How to make a video from photos with music (slideshow), free

Published on August 03, 2026

You can make a video from photos with background music, in Full HD, in three clicks, free and with nothing to install. See how long each photo stays and what to expect.

How to make a video from photos with music: the short answer

Upload the photos (JPG, PNG, WEBP or GIF) and, if you like, a music file; click "Create slideshow" and download an MP4 in Full HD 1920×1080. Without music, each photo stays on screen for 3 seconds. With music, the video lasts exactly as long as the track, split equally among the photos: 90 seconds of music and 3 photos give 30 seconds each. Everything happens in the browser.

What a slideshow video is for

A slideshow is a video where photos appear one after another, like a presentation. Unlike an album, it plays on its own, fits a WhatsApp status, a Reel and the TV at the party. It's the simplest way to turn a folder of photos into a keepsake you can watch:

  • A birthday, wedding or tribute video with someone's photos.
  • A recap of a trip or of a whole year.
  • A post for Instagram, TikTok or a WhatsApp status.
  • A product catalog or portfolio as a video to show clients.

Create the slideshow, step by step

  1. Open the Slideshow (images → video) tool and upload the photos: drag them onto the "Drag your files" area or click "Select files." JPG, PNG, WEBP and GIF are accepted.
  2. Put the photos in order with the list's ↑ and ↓ arrows. If you want music, upload an audio file too; the screen shows "Background track: file name" (only the first track uploaded is used).
  3. Click "Create slideshow (N images)." On first use the video engine gets ready and may take a few seconds.
  4. Download the video: a single file named atlasdocs-slideshow.mp4, at 1920×1080.

How long each photo stays (the one rule you need to know)

  • Without music: 3 seconds per photo. Ten photos make a 30-second video.
  • With music: the video lasts as long as the track, and every photo gets the same time. A 2-minute song with 8 photos gives 15 seconds per photo; if you want the photos to change faster, upload more of them or use a shorter song.
  • There's no per-photo timing and no transitions (no fade or slide effects): the switch is a straight cut.
  • A photo that isn't 16:9 (a phone portrait, an Instagram square) gets black bars on the sides to fit Full HD, with nothing cropped; a photo wider than 16:9 gets the bars at the top and bottom.
  • Image quality is high; the photo is scaled down or up to fit 1920×1080 sharply.

iPhone photos in HEIC aren't accepted by the slideshow tool. Convert them to JPG first (free, and it also runs in the browser), then upload the JPGs. The steps are in how to convert iPhone photos (HEIC) to JPG.

Already have the video and just need music?

The Background music track tool lays an audio file under a video you've already recorded, without re-encoding the picture (video quality stays exactly the same). Upload the video and the music, click "Add music and download" and get an MP4 with "-trilha" added to the name. The volume rule is simple and applies to the whole video: if the video already has sound (speech, ambience), the music plays quietly from start to finish, under the original audio; if the video is silent, the music plays at full volume. There's no section-by-section adjustment and no manual volume control.

  • The music doesn't loop. If it's shorter than a video with sound, the end of the video has no music.
  • Silent video with shorter music: the video ends when the music ends. Pick a track as long as the video or longer.
  • Music longer than the video: it's cut at the end of the video, in both cases.
  • With several videos, the same music is applied to each one ("Apply to N videos" button).

Sign the video with a logo or text

If the video is yours and you want to protect or sign it, the Watermark on the video tool shows a frame of the video and lets you place a logo ("Add logo (image)," in PNG, JPG or WEBP) and/or text ("Add text," with a color picker), both at once if you like. Drag each item wherever you prefer and adjust "Size" and "Transparency." The "Apply and download video" button produces the file with "-marca" added to the name: the audio stays untouched and the video is re-encoded at high quality, with practically no loss. Long videos may take a few minutes. The watermark is applied to one video at a time, the first in the list. If the browser can't show a frame of the video (it happens with AVI and with some MKV and MOV files), the controls don't appear: convert it to MP4 first. That conversion is in how to convert a video to MP4.

Add a watermark or logo to a video, in your browser

The slideshow, the music track and the watermark are all made in your own browser: photos, video and music are never sent to any server. The only download is the video engine, about 9 MB, once, on first use. No app, no account.

From a folder of photos to a Full HD video with music and your own brand, you can put it all together right here, with no complicated editor, and share it wherever you want. If the starting point is a PDF rather than photos, see how to turn a PDF into a video.
