Pick the limit. Below makes it fit.
Enter a maximum file size in megabytes. Below picks the resolution, frame rate, and bitrate for you, then checks the finished file byte for byte. No bitrate math and no quality sliders, just a number.

One number in, a video that fits
- 01
Target size, not guesswork
Tell Below the limit you care about, like 20 MB for Discord or about 18 MB for an email that keeps getting rejected. It works out every encoding setting for you.
- 02
Presets and My Sizes
10, 25, 50 and 100 MB are one tap away, plus three custom slots for the limits you hit again and again.
- 03
Checked byte for byte
Below measures the real output file after encoding, in decimal megabytes, the same unit Photos, email and messaging apps use.
- 04
Private by design
Everything happens on your iPhone. No account, no upload, no analytics, no ads. Your video never leaves the device.
- 05
Photos, Files, Share Sheet, Shortcuts
Compress from wherever the video lives. A Shortcuts action lets it run inside your own automations.
- 06
Your original is untouched
Below writes a new, smaller file and never modifies or deletes the source video.
Common video size limits
Type the limit into Below and it does the rest. These are the ones people hit most, as of October 2026.
| Where | Limit | Good to know |
|---|---|---|
| Discord (free) | 20 MB | Raised from 10 MB in August 2026. Nitro tiers are higher. |
| Gmail, Outlook.com, Yahoo Mail | 25 MB | Email encodes attachments, which adds about a third, so a 25 MB file can still be refused. Aim for about 18 MB. |
| iCloud Mail | 20 MB | Mail Drop sends bigger files as a link when you use Apple Mail or iCloud.com. |
| Text message (MMS) | about 1 to 5 MB | Depends on the carrier. iMessage between iPhones has no published limit. |
Limits change and work or school accounts can differ. If a service tells you a different number, use that one.

Send a note with your device model, iOS or Android version, and what you were trying to compress. That is usually enough to work out what happened.
Common questions
How do I compress a video to under 25 MB on iPhone?
Open Below, pick the video, choose the 25 MB preset and tap compress. Below sets the resolution, frame rate and bitrate itself, then measures the finished file so you know it fits. For email, a lower target such as 18 MB is safer, because email adds overhead to attachments.
How do I make a video small enough for Discord?
Discord lets free accounts upload files up to 20 MB. Enter 20 MB (or a little less, such as 19) in Below, compress, and upload the new file. Your original stays untouched.
My email says the video is too large. What do I do?
Most email services cap attachments at 20 to 25 MB, and the real limit is lower because attachments grow when email encodes them. Compress the video to about 18 MB in Below and attach the smaller copy.
How do I compress a video to an exact size?
Enter the maximum size in megabytes. Below works out the encoding settings, compresses, then checks the real file on disk. You never touch a quality slider or do bitrate math.
Will compressing to a size ruin my video?
Below keeps as much quality as the limit allows by choosing resolution and frame rate for you. Very short clips and very small limits can leave too little room, and Below tells you instead of producing something unwatchable.
My video will not go under the limit I asked for.
Very short clips and very small limits sometimes leave no room for a watchable result. Below tells you when that happens instead of producing something unusable. Raise the limit slightly and try again.
Below says my video is already small enough.
If the original is already under your limit, Below keeps the original quality and tells you so rather than re-encoding it for no reason.
The result is a different size than I expected.
Sizes use decimal megabytes, where 1 MB is 1,000,000 bytes. That is the same unit Photos and most messaging and email services use. Below measures the real output file after encoding, so the size it reports is the size on disk.
I bought Below Pro and it is not unlocked.
Open Below, reach the Below Pro screen, and tap Restore Purchases. Make sure you are signed in to the same Apple Account you used for the purchase. Below Pro is a one-time purchase, so it restores on any device signed in to that account. On Android, open the same Below Pro screen and tap Restore purchases while signed in to the same Google Play account you used to buy it. Pro also comes back on its own when the app opens.
How many free compressions do I get?
The first three successful compressions are free, at full quality and with no watermark. After that, Below Pro unlocks unlimited compressions for a single one-time purchase.
Where did my original video go?
Nowhere. Below never changes or deletes your original. It writes a new, smaller file and leaves the source untouched.
Can I use Below from Photos, Files, or Shortcuts?
Yes. Share a video from Photos or Files and choose Below to compress inside the share sheet. In Shortcuts, use the Compress Video Below Size action with a video and a target in megabytes.
How do refunds work?
Purchases are handled by Apple or Google Play, depending on where you bought. On iPhone or iPad, request a refund at reportaproblem.apple.com. On Android, request it through Google Play (order history).
