Merge Forge

Drop in images, video clips, music, and text overlays — arrange them, preview live, then merge into one final video with smooth audio fades.

Turning a PowerPoint into a video?
Click here first — one quick export step
  1. Open your presentation in PowerPoint, Keynote, or Google Slides.
  2. Use File → Export → Images (PowerPoint/Keynote) or File → Download → PNG image (current slide) repeated per slide, or File → Download → JPEG zipped in Google Slides — every tool has a one-click "export slides as images" option.
  3. Upload the resulting image files below, in slide order.

Browsers can't open or render a raw .pptx file directly — there's no PowerPoint engine built into a webpage — so this one export step stands in for that. Everything after this is automatic.

Your images & video clips

Mix and match — slide images, drawings, clips from Clip Forge or Video Forge. Reorder with the arrows.

Nothing added yet.

Transition between images

Applies between two consecutive images only — video clips always cut in and out cleanly, like a real edit.

Output
Text overlay (optional)

Add lines of text that appear over the video — handy for quotes, captions, or credits.

No text overlays added.

Music & sound (optional)

Layer in music or narration on top of everything above — upload a track (e.g. one you made in Music Forge), record narration live, or use a generated stock track. Got a screen recording from Record Forge? Add it as a clip above.

Want more control over mood/tempo/length? Make one in Music Forge and upload the .wav here instead.

No music or sound added — the merged video will use each clip's own original audio only.

Smooths the start/end of the merged audio (music, narration, and video clip audio together) instead of cutting in or out abruptly.

MERGE FORGE — PREVIEW NOT STARTED
Nothing to merge yet. Add at least one image or video clip on the left, then hit Merge & render.
Rendering…0%

Play preview plays the timeline live, right here, with no export — a quick way to check pacing, transitions, captions, and audio before committing to a full render. Rendering itself happens in real time in your browser, plus a brief moment up front to line up any video clips. Most desktop browsers (Chrome, Edge, Firefox) support this; Safari's support is limited.
