Read the destination limit
Find its current upload limit and accepted formats. A failed upload may also be a connection or format issue.
Estimate a workable bitrate
Use the video-size calculator with duration and combined audio/video bitrate. Leave room for container overhead and variable bitrate.
Create a separate copy
Choose compression settings appropriate to the task. A smaller result can lose detail; text and fine motion deserve a close check.
Test the actual result
Play the exported file, inspect its size, then try the destination. An estimate is not a guarantee of the exported size.
Choose the right action
| Your priority | A useful approach | Before you act |
|---|---|---|
| Keep the original | Retain the full-quality or meaningful version; review replaceable content elsewhere first. | A smaller copy may not preserve edits, movement or all detail. |
| Remove an unwanted item | Inspect it, verify any necessary independent copy and approve only the intended selection. | Deletion in a synced library can affect other devices. Permanent removal ends recovery. |
Where Smart Cleaner helps
Smart Cleaner provides native video compression workflows. The website calculator helps you plan without sending the video to a server.
What it does not do
The calculator does not compress videos, and no tool can guarantee every service will accept a file.

Questions you might still have
Can I delete the original immediately?
First check the full result and keep the original if you may need editing quality or a higher-quality archive.
Does changing resolution always hit a size target?
No. Duration, bitrate, codec and content all affect size. Verify the exported file.
