Create Stunning Slideshows and Videos Online
Whether you're capturing vacation memories, compiling a work presentation, or creating a social media story, an online slideshow maker offers a fast way to bring your photos to life - combining a sequence of images and an optional audio track into a single MP4 presentation in just a few steps.
Image sequence to MP4: what the tool does behind the scenes
Video Maker takes the still images you upload, places them on a timeline in upload order, and renders each frame for the duration you set (1-5 seconds each). Between frames the tool applies a transition (fade or zoom); at the end it encodes the whole sequence into an MP4 container using an H.264 stream so the output plays in every modern browser, phone, and video player without conversion. If you enable audio, an uploaded track is mixed in at export time and trimmed to the slideshow duration. The resolution you pick (320×240 through 1680×1050) becomes the MP4's native size; higher resolutions cost more encode time but look sharper on retina screens.
Keep the images at a consistent aspect ratio before uploading. Mixed aspect ratios - a portrait phone photo next to a widescreen screenshot, for example - get letterboxed with black bars or cropped to fit the output resolution you picked, rather than resized to match each other.
Picking a frame duration and resolution that match the intent
Social recap (2-3s per frame, 1280×720). Use the default 3-second frame with a 16:9 resolution so each image has time to read without the video feeling slow. Keep total duration under 60 seconds for Instagram, TikTok, and LinkedIn autoplay.
Product announcement (4-5s per frame, 1600×900). Longer frames let viewers absorb specs or a short caption. Pick a 16:9 resolution for site embeds and email previews.
Personal memory / family recap (3s per frame, 1280×720 or 1440×900). A comfortable middle ground. 16:10 or 16:9 works well for laptop playback.
Event signage (1-2s per frame, 800×600). Faster cadence feels alive on a kiosk display. Lower resolution keeps file size small if the screen is SD.
Audio matters. If you include music, pick a track whose length matches your total slideshow duration (frame count × frame duration). Mismatched audio is either cut mid-note or plays over a black tail.
Privacy: what happens to your uploaded files
Video Maker uploads your images (and audio, if included) to our server, where the slideshow is encoded into the MP4 - the encoding does not happen inside the browser tab. The upload runs over a secure connection, and both the source files and the generated video auto-delete from server storage after a short retention window; nobody reviews the content in between. If you need a workflow with no upload step at all, HD Video Converter runs entirely on-device via FFmpeg.wasm - though it converts an existing video rather than building a slideshow from images.
Want to edit the MP4 output or run a custom encoding command? Pass the result through All Video Converter for quick format changes (WebM, MOV), or use FFmpeg Online for precise filter chains. For an animated GIF instead of a full video, GIF Maker accepts the same image sequence and outputs a lightweight animation.
Picking the output format for your audience? Read MP4 vs WebM for the web for the decision rule: MP4/H.264 wins for universal playback across email, LinkedIn, and legacy platforms; WebM/VP9 wins for bandwidth and modern browsers where size matters. The guide also covers when to ship both variants via a <source> fallback so every viewer gets a high-quality playback without a codec gamble.
Frequently Asked Questions
Can I add video clips, or only images?
Video Maker builds the slideshow from a sequence of still images plus one optional audio track - it does not accept existing video clips as input. Upload the photos in the order you want them to appear, and the tool renders each one for the duration you set. If you already have a video file to work with, use one of the converter tools linked in the last question below instead.
Is there a built-in music library, or do I upload my own track?
You upload your own audio track - Video Maker has no built-in music library. Toggle audio on, add one file, and the tool mixes it in at export time, trimmed to the slideshow's total length (frame count times per-image duration). Pick a track whose length is close to that total so the audio does not cut off mid-note or leave a silent tail.
Can I add text captions or effects to the slideshow?
Video Maker does not overlay text or apply arbitrary visual effects. Each image is shown as-is, and the only motion between frames is the transition you choose - Fade or Zoom. If you want a caption on a slide, add the text to the image itself before uploading (any image editor works), then include that finished image in the sequence.
What settings control how the video looks?
Three settings: per-image duration (1 to 5 seconds each), the transition between frames (Fade or Zoom), and the output resolution (320×240 up to 1680×1050). Higher resolutions look sharper but take longer to encode. Keep your images at a consistent aspect ratio - mixed portrait and widescreen images get letterboxed or cropped to fit the resolution you pick.
What format is the output, and can I post it to social media?
The output is a single MP4 file encoded with H.264, so it plays in every modern browser, phone, and video player without conversion. Video Maker does not post to social platforms directly - you download the MP4, then upload it yourself to Instagram, YouTube, LinkedIn, or wherever you need it. Keep the total length under 60 seconds if you are targeting autoplay feeds.
Have an existing video to convert?
Video Maker builds an MP4 from a sequence of still images and optional audio - it is the build path, not the format-switch path. To convert a video file you already have (MP4, WebM, MOV, AVI, MKV) to a different container or extract the audio track to MP3, AAC, OGG, FLAC, M4A, or WAV, use All Video Converter (server-side, supports large clips) or HD Video Converter (runs locally in your browser via FFmpeg.wasm, no upload). For precise filter chains and custom encoder flags, FFmpeg Online accepts the same input set.
