Frequently asked questions

  • How to reduce video file size?

    The easiest way to make video files smaller is to use an online tool like ours. Here's how:

    1. Open this page and drag your clip into the upload area (or click the + button to browse).

    2. Wait a moment while our tool reduces video size for you.

    3. Download the lighter version when it's ready, or come back to it later in your account.

  • Does compressing a video reduce quality?

    Our video compressor keeps the resolution and frame rate close to the original, so playback still looks clean on a phone, laptop, or TV.

    If you compare the two files side by side at full screen, you might spot a small difference, but for sharing, posting, or emailing, the compressed version holds up well.

  • How to compress a video on iPhone?

    Since our tool runs entirely in the browser, you can compress video clips on an iPhone without installing an app. Here's how:

    1. Open this page on your iPhone in Safari or Chrome.

    2. Upload your video file, then wait a few seconds while the tool shrinks it.

    3. Download the compressed version right away, or grab it later from your PDF Guru account.

  • What happens when you compress a video?

    The video looks and sounds exactly the same (same length, same picture, same sound), but the file itself gets smaller. Our video size reducer packs the data more tightly, so the clip takes up less storage and is easier to send or upload. You might notice a tiny dip in sharpness if you look closely, but on a phone or laptop screen, the result looks practically the same as the original.

  • How to compress a video for email?

    Most email providers cap attachments at around 25 MB, which often isn't enough for video files. Drop your clip into our online video compressor, wait a moment, and download the smaller version. From there, you can attach it to your email like any other file. If it's still too large, run it through the tool a second time.

  • Is it safe to compress video files online?

    PDF Guru is used by people around the world to handle their documents online, and we take privacy seriously. Every upload is encrypted in transit, your data is handled in line with GDPR, and your media files stay in your private account. Compress video size with ease!

  • What video formats can I compress?

    Our online video compressor supports all popular formats, including MP4, MOV, AVI, MKV, WebM, FLV, and more. You can upload a clip recorded on a phone, camera, or screen recorder without worrying about conversion first — just drop the file in and the tool will handle the rest.
