How to use the video MD5 tool on iPhone and iPad

Change MD5 creates a processed file from a video. This guide shows its entry and result; a byte-level file digest is not a measure of improved picture quality or changed video content. Screenshots come from an iPhone 17 Pro Max simulator running iOS 26.0. The app interface is in English.

01Steps

Open Change MD5 in Process

Tap Process in the bottom navigation. Find Change MD5 in row 6, in the middle column, and tap the entry marked by the arrow.

02Steps

Choose a video and wait for processing

After opening Change MD5, use Choose from Photos or another appropriate source. The test uses a previously exported short clip through Quick Edit. Processing starts directly without a separate settings page.

There is no target-digest input

This workflow shows no MD5 input field or format parameters. Do not treat it as a tool for choosing any arbitrary digest value.

03Steps

Check the result, then save or keep processing

A new _md5.mp4 file appears, showing about six seconds. The test reached the output page but did not compare input and output MD5 values. If you need digest evidence, calculate the actual hashes of both files separately.

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?

This guide does not describe MD5 changes as enhancement or compression. Use Transcode Video for compression.

Does a changed digest change my rights to use the video?

No. File-digest changes do not alter content rights.
