PNG to Video Converter

Convert PNG to Video: What This Tutorial Covers

This walks you through turning a still PNG into a real video file — a static clip that holds your image on screen for a set number of seconds. It does not animate or add motion; it builds a fixed-length video you can post where a platform demands a video instead of a picture: a placeholder, a title card, an audiogram backdrop, or a slide. This guide covers the three settings that decide whether the output matches what you pictured — Image Duration, output format, and Background Color — plus what happens to transparency and audio along the way.

How to Convert PNG to Video

1. Upload Your PNG File: Drag and drop your PNG onto the page or click "+ Add Files". Add several at once if you want a single multi-image clip; the tool accepts PNG and APNG.
2. Set Image Duration and Output Format: Choose how long each image stays on screen with the Image Duration dropdown (default 5 seconds per frame), then pick your container from the Video File Extension dropdown (MP4, encoded with H.264, is the default).
3. Set Background Color and Merge Strategy: Background Color (default white) fills any letterbox or pillarbox bars added when your image's shape doesn't match the video frame. Use Merge images to combine all uploads into one video, or Video per image for a separate clip per file.
4. Convert and Download: Click "Convert" and download the result. No sign-up, no watermark.

Walk-through: Duration, Silence, and Background

Three things surprise people most when a still becomes a video, so set them deliberately.

• Length comes entirely from Image Duration. With one PNG, the duration you pick is the whole clip: "10 seconds per frame" gives a 10-second video. With several PNGs merged into one video, total length is the per-image duration multiplied by the number of images. The sub-second options (1/24s, 1/30s, 1/60s) show each image for a single frame at 24, 30, or 60 fps — use those only when assembling a true frame-by-frame sequence, not a slideshow of stills.
• The clip is silent. A PNG carries no audio, and image-to-video output has no audio track at all. That is expected, not a bug. To add music or narration, make the video here first, then mux in a soundtrack with a separate video tool.
• Background Color only pads the frame — it does not recolor transparency. It fills the letterbox/pillarbox bars that appear when your image's aspect ratio differs from the output frame. It does not fill the see-through areas inside a transparent PNG; those are handled by the encoder (see the transparency notes below).

Which Output Format Should You Pick?

MP4 (H.264) is the safest default for social platforms and broad device playback. The Video File Extension dropdown also offers MOV, MKV, WEBM, AVI, and many legacy containers, each with a sensible default codec.

Common Errors and How to Fix Them

• "My logo's transparent background came out white." Expected — standard video has no alpha channel, so transparent pixels are composited onto the Background Color (white by default) when encoded. To place a specific color behind a transparent logo, pick it from the Background Color dropdown, or flatten the PNG onto that color first in an image editor, then convert.
• "The clip is far too short or far too long." That is the Image Duration value. For one image it is the whole runtime; for merged images it multiplies by the image count.
• "I uploaded several PNGs but got several separate videos." The Merge strategy toggle was on Video per image. Switch it to Merge images for one combined clip.
• "The video has no sound." Correct — a PNG has no audio, so the clip is silent. Make the video here, then add a soundtrack with a video tool.
• "The image looks soft or the text got fuzzy." H.264 uses 4:2:0 chroma subsampling, which can soften sharp colored edges and small text. Raise the Quality Preset to Very High and keep the resolution at your source size instead of upscaling a small PNG.

When This Doesn't Work

This tool builds a static clip from a still image — it is not an animator and will not add camera motion, zooms, or transitions. If you want a slideshow with transitions or a frame-by-frame animation, start from a multi-image sequence: the image to video converter accepts a wide range of image formats and stitches them in upload order. If you need a genuinely transparent video overlay, a still PNG converted here is the wrong source — every video output is flattened to an opaque frame. Animated PNG (APNG) files are accepted but treated as a still: only the first frame is used. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.

Frequently Asked Questions

Why is my PNG-to-video clip silent?

Because a PNG contains no audio, and image-to-video conversion produces no audio track. The output is silent by design. If you need sound, generate the clip here first and then add an audio track with a separate video tool.

How long will the output video be?

It equals the Image Duration you set. For a single PNG that is the whole clip — 5 seconds per frame gives a 5-second video. For multiple images merged into one video, the length is the per-image duration times the number of images.

Why did the transparent part of my PNG turn white in the video?

Standard video is encoded in a pixel format (yuv420p) that has no alpha channel, so transparency cannot be stored. When the clip is encoded, transparent areas are composited onto the Background Color (white by default), so they render in that colour. Change the Background Color before converting to control what shows there — the same colour also fills the letterbox/pillarbox bars around the frame.

Can I keep my PNG's transparency in the video?

Not from this converter. The WebM format's VP8 and VP9 codecs can carry an alpha channel — Chrome has rendered alpha-transparent WebM since Chrome 31 per Chrome's own documentation, though Safari does not — but that requires a YUVA pixel format, and this still-to-video pipeline outputs opaque frames. If your goal is a see-through overlay, keep the asset as a PNG or use a dedicated transparent-video workflow instead.

What's the difference between "Merge images" and "Video per image"?

Merge images (the default) combines every PNG you uploaded into one video, shown in upload order, each for the Image Duration. Video per image renders a separate clip for each file instead, which is what you want when you need one short video per picture rather than a slideshow.

What frame rate does the video use?

The frame rate is derived from Image Duration: 1 second per frame is 1 fps, 5 seconds per frame is 0.2 fps, and so on. Those low rates are fine for a static slideshow. If you need standard playback rates, use the sub-second options — 1/24s, 1/30s, or 1/60s show each image for one frame at 24, 30, or 60 fps.

Which format should I export — MP4, MOV, or WebM?

MP4 (H.264) is the safest default and plays almost everywhere. Pick MOV if you are importing into Apple software or a video editor, MKV for a flexible archival container, and WEBM (VP9) for a web-native file that is often smaller at similar quality. All of them output opaque video, so none will preserve PNG transparency.

Does converting a PNG to video reduce image quality?

Slightly, because H.264 is lossy and its 4:2:0 chroma subsampling can soften sharp colored edges and fine text. In our testing, a single 1080p PNG held for 5 seconds as MP4 (H.264) at the Very High preset lands in the low hundreds of kilobytes — after the first frame every identical frame compresses to almost nothing — so keeping the Quality Preset high costs very little file size. To minimize softening, keep the resolution at your source size rather than upscaling.

Are my uploaded PNG files kept private?

Yes. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion. There is no sign-up and no watermark, and your files are never shared or made public.
