From source file to delivery
Find a local original
Choose the video in the upload area. If a Photos item exists only in the cloud, download it to the device first; a share link is not a local video file.
Choose a size or a preset
Use Balanced for an ordinary sharing copy. If a form gives a maximum file size, use Target size with some room below that limit.
Download and share the new file
After compression, download the result and open it from your browser downloads or file manager. Share that file rather than selecting the original again in Photos.
Which Android file should you choose?
| What you see | What to do | Why it matters |
|---|---|---|
| Cloud thumbnail in Photos | Download the original to the phone | A preview or sharing URL is not the source file |
| Video in Downloads or DCIM | Select that local file | The browser can upload the selected bytes |
| Two versions after compression | Check size and play the downloaded copy | Gallery ordering can make the original look like the newest result |
Use the local file, not a cloud thumbnail
The file picker and download folder may have different names, but the encoding task is the same. Select a local video, choose the output constraint and save the result. Device branding does not change the amount of detail a small file can retain.
A cloud backup can make a video visible without keeping the full file on the phone. If selection stalls before the upload begins, check that the original is available locally and that the browser has access to the selected item. Do not repeatedly submit the same video while an earlier upload is still running.
Check the copy before clearing phone storage
Play the downloaded MP4 through to the end, listen to the audio and inspect the part with the most movement. A small preview can hide blur that becomes obvious when the recipient opens the video full screen.
Keep the original until the new copy has been delivered and backed up where you need it. Downloading a compressed result does not replace or remove the original in Photos. If saving fails, check local free space before trying another encode.
Questions before you compress
Can I compress a video on Android without installing an app?
Yes. This page uploads and encodes the selected video through a cloud service. It does not install an Android APK and does not work offline.
Why is the video still too large when I share it?
Check that you selected the downloaded result rather than the original gallery item. If the result itself exceeds the destination limit, use a smaller target and check the actual downloaded byte size.
Where does the smaller video go?
The browser controls the download location, usually its Downloads list or a folder shown in the Android file manager. It may not appear in the same album as the original.
