JPG to MPEG Converter

JPG to MPEG: MPEG-1 or MPEG-2?

This page holds a still photo on screen for a length you choose and writes the result as an MPEG program stream — the .mpeg file that DVD authoring tools, set-top boxes, and older broadcast hardware still expect. The one real decision is the Video Codec setting, because .mpeg is a container that can carry either MPEG-1 or MPEG-2 video, and they are genuinely different standards. Short answer: MPEG-2 is preselected and is what you want in almost every case, especially if a DVD is involved; pick MPEG-1 only when you are targeting Video CD or a device old enough to predate DVD.

MPEG-1 vs MPEG-2 Side by Side

When to Pick MPEG-2

• You are authoring a DVD. Nothing else plays on a DVD player, and authoring tools such as DVDStyler and Adobe Encore expect MPEG-2 video arriving as a .mpg, .mpeg, .m2v, or .mpeg2 file.
• You are feeding broadcast or set-top hardware that lists MPEG-2 in its input specification.
• You want higher output resolutions than standard definition — MPEG-1 was built around roughly VHS quality and does not carry HD frames well.
• You are unsure. It is the preselected option here for a reason: it is a strict superset of what MPEG-1 does for this kind of job.

When to Pick MPEG-1

• Your target is Video CD, or a player or embedded device from the pre-DVD era.
• You need the widest possible decoder compatibility for a low-resolution still, and file size is not a concern — MPEG-1 is one of the most universally decodable video formats ever shipped.
• You want to avoid any lingering licensing question entirely; MPEG-1 is no longer covered by essential patents at all.

How to Convert JPG to MPEG

1. Upload Your JPG File: Drag and drop your .jpg, .jpeg, or .jfif onto the page or click "Add Files". Several photos can go in one job.
2. Choose the Video Codec: Under Advanced Options, Video Codec offers MPEG-1 and MPEG-2, with MPEG-2 preselected. Leave it on MPEG-2 unless you specifically need Video CD compatibility.
3. Set Duration, Merge Strategy, and Video Resolution: Duration decides how long each still is held (5 seconds per frame by default, from a single frame up to 10 seconds). Merge strategy starts on "Merge images", chaining all uploaded photos into one clip. Video resolution starts on "Keep original" — this is the setting that determines your file size, for the reason explained below.
4. Convert and Download: Click "Convert" and download your .mpeg. No sign-up, no watermark.

What Actually Controls the File Size

MPEG-2 has no constant-rate-factor mode. It is a pure bitrate codec, and its encoder fails outright if it is handed a target too low for the frame size — so our pipeline computes a minimum bitrate from the output resolution and never encodes below it. On a still-image source there is no source bitrate for a quality setting to scale from, which means all three entries under File Compression — Quality Preset, Constant Quality, and Constraint Quality — end up at that same resolution-derived floor. Changing them does not change an MPEG-2 encode of a photograph. Video resolution does.

Duration is the other half of the size equation. The still-image encode writes one frame per second of Duration, so a 5-second setting produces a five-frame clip whose container declares a five-second runtime; ten photos merged at 5 seconds each gives a 50-second stream. Halve the Duration or drop a resolution tier and the file shrinks proportionally. The output is silent throughout — a photograph has no audio, so the audio codec control is hidden on this page and no track is written.

Frequently Asked Questions

Why doesn't the Quality Preset change my MPEG file?

Because MPEG-2 does not support constant-rate-factor encoding. Quality settings on modern codecs work by moving a CRF value or by scaling a source bitrate, and a still photograph supplies neither — so every compression mode resolves to the minimum bitrate our encoder calculates from the output frame size. That floor exists because MPEG-2 encoders error out with "bitrate too low" when asked to compress a large frame too hard. If you need a smaller file, lower Video resolution or shorten Duration; if you need real quality control, an MP4 conversion gives you a working CRF ladder.

Is .mpeg different from .mpg?

No, they are the same MPEG program stream carrying MPEG-1 or MPEG-2 video. Two spellings exist only because early Windows required three-character extensions, which clipped .mpeg to .mpg, while other systems kept the longer form. Both open in the same software and both are accepted by DVD authoring tools. The sibling JPG to MPG converter writes the identical file under the shorter name.

Does this create motion, or just a photo held on screen?

It holds a single image — no pan, zoom, fade, or transition, and no audio. Every frame in the clip is the same picture. To play several photos in sequence, upload them all and leave Merge strategy on "Merge images"; each is shown for the Duration you set, giving you a plain slideshow without an editor. Choose "Video per image" for one separate clip per photo.

Will the MPEG keep my photo's original resolution?

By default, yes — Video resolution starts on "Keep original", so the frame size matches your image, rounded to even dimensions as the codec requires. For DVD authoring you will usually want to override that: DVD-Video permits specific frame sizes such as 720 × 480 for NTSC, so set an explicit Width × Height or pick a fixed-resolution preset rather than shipping an arbitrary photo dimension to your authoring tool.

What happens if my photo's aspect ratio doesn't match the resolution I set?

The picture is letterboxed rather than stretched, and Background Color fills the empty bars — white by default for image sources, with the full list of named colours to choose from. If you would rather crop than pad, resize the photo to the target aspect ratio before uploading.

Can a browser or a phone play the resulting file?

Usually not directly. Browsers and mobile operating systems do not natively play MPEG program streams, which is exactly the trade you make for compatibility with DVD and set-top hardware. Desktop players such as VLC handle them without complaint. For phones and the web, convert the photo with JPG to MP4 instead, or take an existing file through MPEG to MP4.

Which codec do DVD authoring programs actually need?

MPEG-2. The DVD-Video specification is built on MPEG-2 video with restrictions on frame size, aspect ratio, frame rate, and a 9.8 Mbit/s video ceiling, and a DVD player will not accept anything else. MPEG-1 in a .mpeg file is a Video CD-era stream; some authoring software will transcode it for you, but you have then paid for two encodes. Leave Video Codec on MPEG-2 and set a DVD-legal resolution before converting.

How are my uploaded files handled?

They are uploaded over an encrypted connection, encoded on our servers, and deleted automatically a few hours afterwards. There is no sign-up, no watermark, and nothing you upload is shared or made public.
