01
Open Change MD5 in Process
Open Process, then tap Change MD5.
02
Choose a video and wait for processing
Choose a video from Photos or another available source. Processing starts directly without a separate settings page.
There is no target-digest input
There is no field for entering a target MD5. This tool does not let you choose an arbitrary digest value.
03
Check the result, then save or keep processing
Check the new file, then save or share it. If your workflow requires a different MD5, calculate and compare the original and output hashes; a new filename alone is not confirmation.
Preview and save
Play the result and check picture, duration, and sound, then tap Save to Photos. The first save may require permission to add photos and videos. After the success message, check the file in Photos.
What the other buttons do
Keep Processing takes the result into tool selection. Share File opens sharing options. Done closes the result page; it does not save to Photos.
Troubleshooting
Verify the actual files
A changed filename does not prove the MD5 changed. Calculate and compare input and output hashes if your use depends on the digest, rather than relying on the completion screen.
Frequently asked questions
Does it improve quality or reduce file size?
An MD5 hash identifies file contents; it is not a measure of video quality or compression. Use Transcode Video to reduce file size.
Does a changed digest change my rights to use the video?
No. File-digest changes do not alter content rights.
