Online Photo, Video & Music Merger

Photo & Video Merger

Join photos and videos into one MP4. Add music, steady shaky clips, trim, fade. Free, no upload — everything happens on your own device. Read the guide for examples of every setting.

For long videos, open the tool in its own tab so it can save the file straight to your disk. Open full version ↗

1. Add your photos and videos

Drag files here or use the button below

All videos, stabilize: choose… Off Light Strong

Clips play in the order shown. Use the arrows (or drag on a computer) to reorder. Press Edit on a clip to trim, mute, rotate, stabilize or add a zoom effect.

2. Video settings — already set for YouTube, change only if you need to

Output size YouTube 1080p, 16:9 (1920×1080) YouTube 720p, 16:9 (1280×720) 1440p landscape (2560×1440) 4K landscape (3840×2160) Vertical 9:16 (1080×1920) Square (1080×1080) Match the first clip

Empty space around a clip

Only used when “Fit inside” is chosen above.

Between clips

Applies between different clips only, never at the cuts you make inside one video.

Seconds per photo Quality Standard (smaller file) High (recommended) Very high (large file) Fade / dissolve length (seconds)

Start and end Fade in at the start, out at the end

3. Music (optional)

Music volume:

70%

Original video sound:

100%

Original sound

Mix with music Replace with music

Lower the music when the video has sound Off A little Medium (good for speech) A lot

If the music is shorter Repeat it until the video ends

Fade out at the end (seconds)

Music is cut automatically when the video ends.

4. Merge

Where will my finished file be saved?

• Computer (Chrome or Edge): a “Save as” window opens when you press Merge. Pick any folder or drive, including a USB stick or external hard disk. The video is written straight there, so it needs almost no space on your internal drive.
• If Edge says “You can’t save to this folder”: tick Use a normal browser download, then set your browser’s download location to the card or drive (Edge: Settings → Downloads → Location). The video is built in your browser’s own storage first, so it needs free space on your main drive until the download finishes.
• Android phone (Chrome): the file goes to your Downloads folder. To use the SD card, open Chrome → Settings → Downloads → Download location. You can also tap Share / Save to… after merging.
• iPhone / iPad (Safari): the file is saved in the Files app. Tap Share / Save to… → Save to Files and choose where.
• Very long projects: choose Save as several parts. Each part is a complete video, so if something goes wrong you only lose the part in progress. Afterwards use Join parts below to make one file, quickly and without re-encoding.

A web page cannot force a phone to use the SD card; that choice belongs to your phone’s settings.

Save as One file Several parts of about 20 minutes Several parts of about 30 minutes Several parts of about 45 minutes Several parts of about 60 minutes

  Use a normal browser download instead of the “Save as” window

5. Join parts and projects

Join parts combines MP4 files made by this tool (for example the parts of a long project) into one file. It copies the video as it is, so it is fast and loses no quality. The parts must come from the same project settings.

---

Project: save your clip order and edits to a small file, then load it later. After loading, add the same photo and video files again and everything is put back.

Guide: what every setting does, with examples

Quick start (5 steps)

1. Add your photos and videos. They play in the order shown; use the arrows or drag to reorder.
2. Press Edit on a clip only if it needs something: cut out parts, mute, rotate, stabilize, zoom.
3. Leave Video settings as they are for YouTube (1080p, high quality, blurred sides).
4. Optionally add music.
5. Press Merge. Keep this tab open and the screen awake until it says Done.

For a long video (more than about an hour) choose Several parts under “Save as”. If something goes wrong you keep the finished parts, and Join parts makes one file afterwards in a few seconds.

Recommended settings for a YouTube video

• Output size: 1080p 16:9. Choose 720p on a slow computer or phone. Choose 4K only if your clips are 4K and your computer is fast.
• Different shape: Fit inside. Empty space: Blurred copy.
• Quality: High. Between clips: Straight cut for events and trips; Dissolve for slideshows.
• Seconds per photo: 4–6 seconds. Add a slow zoom to photos so they do not feel frozen.
• Music: 15–25% volume if people speak in your clips; 60–70% when the clips have no talking. Turn on “Lower the music when the video has sound”.
• Stabilize: Off, except for shaky clips (see below).

When a clip has a different shape

A vertical phone clip does not have the same shape as a wide YouTube video. You decide what happens:

Fit insideEverything you filmed stays visible. Empty space appears at the sides.

Fill the frameNo empty space, but the top and bottom (red stripes) are lost.

Tip: use Fit inside for vertical clips and photos. Use Fill the frame only when you do not mind losing the edges, for example a wide clip in a square video.

Empty space around a clip

This only matters with Fit inside. It decides what fills the empty sides:

Blurred copyA soft blurred version of the same picture. Looks polished and is what most phone editors do.

Black barsPlain black. Slightly faster to make.

Between clips (transitions)

Straight cutThe next clip starts at once.

Fade through blackFades out, then fades in.

DissolveThe two clips overlap for a moment.

Fade / dissolve length is how long the effect lasts (0.6 s is a good value). Transitions are applied between different clips only. The cuts you make inside one video are always straight cuts.

Fade in at the start, out at the end makes the whole video start from black and finish to black, and fades the music in and out too.

Cutting out parts of a video

Press Edit on a video, find the part you do not want, and press + Add a cut. A cut removes the part between from and to. You can add as many cuts as you need to the same video (10, 20, more).

Example: 3 cutsRed parts are removed. The blue parts stay and are joined together with straight cuts.

• Play the video, pause at the exact spot, then press Use current time beside from or to. Or type a time such as 1:25.5.
• Click the bar to jump to that point. The black line shows where the video is now.
• Delete a cut with the × button. Reset this clip removes all edits of the clip.
• The sound is cut together with the picture.

Titles and text on a clip

In a photo’s or video’s Edit panel press + Add text / title, type the words, choose Place (Top, Middle or Low), the Size, and the seconds it is shown from…to. You can add several texts to one clip, each with its own place and time.

• For a video the seconds are the same as the time shown in the player in the Edit panel. Pause the player where the text should appear and press Use current time.
• For a photo the seconds start at 0 when the photo appears (a 5-second photo can show text from 0 to 5).
• Long text wraps onto several lines by itself. Press Enter for a new line.
• The text is white with a dark outline so it can be read on bright and dark pictures. The small preview in the Edit panel is approximate; the final video uses the chosen output size.
• A text that falls inside a part you cut out of the video is not shown.

Duplicate a clip

Inside a clip’s Edit panel, Duplicate this clip adds a copy right after it. Use it when you want the same video or photo twice with different edits, for example the same photo shown again at the end with a zoom. For several parts of one video you do not need to duplicate: just add several cuts.

Nothing is duplicated unless you press this button.

Stabilization (steadier shaky video)

What it does. The tool measures how the camera moved in every frame, works out a smooth path the camera should have followed, and shifts and tilts each frame to match it. Fast jitter disappears; slow, deliberate pans stay.

Why the edges are cropped. Moving frames around leaves thin empty borders. To hide them, the picture is enlarged a little. The crop is a side effect of stabilizing, not the cause of the steadiness. Light crops about 4–8% of the edges; Strong about 10–16%.

How to choose. Press Preview & compare in the clip’s Edit panel. It plays 5, 10 or 15 seconds of that clip three ways side by side (Off, Light, Strong), starting where the video above is paused. Pause the video at a shaky moment before pressing the button. Press Use Light or Use Strong under the one you like.

• Walking or handheld shake: Light is usually enough.
• Very shaky or running footage: Strong.
• Footage on a tripod or already smooth: leave it Off.

Costs and limits. Stabilized clips are analysed first, so merging takes longer. It cannot fix blur, the “jelly” wobble of some phone cameras, or a subject that is itself moving a lot. In the preview you see exactly what you will get.

Music

• Music volume / Original video sound: how loud each is. Original sound can go above 100% for quiet clips.
• Mix with music keeps the sound of your clips and plays music under it. Replace with music removes the clip sound completely.
• Lower the music when the video has sound: the music gets quieter automatically while someone talks or there is noise, and comes back in the silent parts. Medium suits speech.
• Repeat it until the video ends loops a short song. The music is always cut when the video ends, and fades out over the last seconds you choose.
• Per clip, you can mute or change the volume in Edit.

Photos: time, zoom and pan

“Seconds per photo” sets the default; each photo can have its own time (the box in its row). In a photo’s Edit panel, Zoom / pan adds a slow zoom in, zoom out, or pan left/right. Photos are never stretched: they follow the Fit/Fill choice above.

Quality and file size

Roughly, one minute of 1080p video is about 25 MB at Standard, 40 MB at High and 55 MB at Very high. A 1-hour video is therefore about 1.5, 2.4 or 3.3 GB. YouTube re-encodes everything, so High is the best balance.

Where is my finished video saved?

• Chrome / Edge on a computer: a Save window opens when you press Merge. Pick any drive, including an SD card or USB disk. The video is written straight there.
• If Edge refuses a folder (“You can’t save to this folder”), tick Use a normal browser download, or pick another folder or a drive formatted as exFAT/NTFS (FAT32 cannot hold files over 4 GB).
• Phones: the file goes to the Downloads folder; on Android you can change the download location in Chrome’s settings. The Share / Save to… button lets you pick an app or folder.

Long projects: save as parts, then join

Under Save as choose parts of 20–60 minutes. The tool starts a new part at a clip boundary, so no clip is split. Each finished part is a complete video file. If something fails or you cancel, parts already saved stay safe.

Then use 5. Join parts: choose the part files and press Join. It joins without re-encoding, so it takes seconds and loses no quality. The parts must come from the same run of the tool (same size and quality).

Save and load a project

Save project writes a small file with your clip order and all your edits and settings (not the videos themselves). Later, press Load project, then add the same photo and video files again. The order, cuts, stabilization and settings are put back. Files are matched by name and size, so do not rename them.

Problems and tips

• The page says “not responding” during a long merge: wait. The work is heavy but it continues. Close other heavy tabs and programs.
• Do not cancel a long single-file merge unless you must; it starts again from zero. Using Several parts avoids this.
• A file cannot be read: it may be damaged or in an unusual format. Try converting it to MP4 (H.264).
• Slow computer: choose 720p, Standard quality, and keep stabilization Off.
• Your files never leave your device. Nothing is uploaded.

Your files never leave your device. Keep this tab open and your screen awake while merging. Version 4.2
