5MB satisfies strict forms, legacy email gates, and quick DM uploads. Drop your clip and FitToMB targets the exact size for you.

Drop video or click to upload · Presets: 5MB · 8MB · 10MB · 25MB

🔒 Secure & Private: Files auto-delete after 1 hour. No sign-up required.

Keep videos tiny without guesswork

When portals or ticketing forms limit uploads to 5MB, there's no room for trial and error. FitToMB calculates the bitrate automatically so you can focus on the story. Need channel-specific pointers? Bookmark the email compression guide and the Discord size playbook for backup options.

Steps to compress a video to 5MB

  1. Upload your video. Drag in any MP4, MOV, MKV, or WebM-no account required.
  2. Select the 5MB preset. Lock the size at 5MB or type the exact number you need.
  3. Adjust resolution if needed. Keep 720p for short clips or choose 480p/360p for longer recordings.
  4. Compress & download. FitToMB runs a two-pass encode and returns a share-ready MP4 under 5MB.

Planning a longer tutorial? Run the Video Bitrate Calculator first so you know how much bitrate you can spend before exporting.

Need a little more room? Hop to the 8MB workflow when 5MB is too tight.
Got approval for richer clips? Shift to the 15MB preset for longer explanations.
Targeting Discord limits? Follow the 10MB playbook for standard server caps.
Need inbox breathing room? Use the 20MB guide when Gmail or Outlook allows more headroom.
Sending email attachments? Use the 25MB exact-size guide for inbox-friendly exports.

How to stay under 5MB

Use these conservative targets before exporting-landing slightly under keeps uploads successful.

Clip length Suggested resolution Target video bitrate Notes
< 20 seconds 720p @ 30 fps ~800 kbps Perfect for quick teasers and promo snippets.
20-45 seconds 720p @ 24 fps ~600 kbps Lower the frame rate to stretch runtime while keeping UI text readable.
45-75 seconds 480p @ 30 fps ~420 kbps Great for support walkthroughs and help-desk uploads.
> 75 seconds 360p @ 24 fps ~300 kbps Split long clips or provide a higher-quality download link.

FAQ

How does FitToMB stay under 5MB?

We calculate the bitrate for a 5MB ceiling and run a two-pass encode so the final MP4 lands safely under the limit.

Why would I target 5MB?

Some ticketing systems, chat apps, and legacy email gateways reject files over 5MB. Using a precise preset avoids manual retries.

Will the video still look good?

Short clips stay sharp at 720p. For anything longer than ~30 seconds, cap resolution at 480p or 360p to protect text clarity.

Does audio count toward the limit?

Yes. Keep audio between 64-96 kbps and leave a little buffer if you include subtitles or metadata.
