compressvid.ioReduce video file size online without visible quality loss. Pick a target like 19 MB for Discord or 24 MB for Gmail, and get a clean MP4 back — no install, no watermark.
Quality mode targets CRF and does not guarantee an exact MB size. Switch to target size or bitrate for a hard limit.
Only use this for very old devices or playback issues (reduces compression ratio).
Compress a large video into a smaller file online — no software to install and no watermark on the result.
Drag and drop an MP4, MOV, MKV, AVI, WebM or other video file, or pick one from your phone or computer. Free uploads go up to 1 GB.
Pick a preset like “50% smaller”, tap a size such as 20 MB or 25 MB, or type any size in MB. Need more control? Switch to Advanced for codec (H.264/H.265) and quality settings.
The video is compressed on our cloud servers. Download the result as an MP4 — no watermark — and send it wherever it needs to go.
Most “video too large” errors come from a platform’s upload cap. Compress to a target a little under the limit so container overhead never pushes you over.
| Where you’re sending it | Upload limit | Compress to |
|---|---|---|
| Discord (free) | 20 MB | 19 MB |
| Discord Nitro Basic | 50 MB | 48 MB |
| Gmail attachment | 25 MB | 24 MB |
| Other email (Outlook, Yahoo, work mail) | Often 20–25 MB | 19 MB to be safe |
| WhatsApp, Telegram, Messenger | Large files allowed, but chats re-compress video | Smaller file = faster send, your quality settings |
| Forms, LMS & job portals | Usually set by the site (often 10–100 MB) | 5% under the stated limit |
Discord raised its free upload limit from 10 MB to 20 MB in August 2026 — older guides that say “compress to 8 MB or 10 MB” are out of date. Full breakdown: Discord file size limit. Limits checked October 2026; platforms change them, so check the official help page if you’re right at the edge. Step-by-step: how to compress a video to an exact file size.

Most compressors make you guess. This one starts from the size you need and works backward.
Type the size you need in MB — 19 MB for Discord, 24 MB for Gmail — or use a percentage preset. The bitrate is calculated from your video’s length so the result lands close to your target.
Choose H.264 for maximum compatibility or H.265 for roughly 30–50% smaller files at similar quality. Advanced mode exposes CRF quality, resolution and bitrate controls.
Compress videos up to 1 GB free (10 GB on paid plans) from MP4, MOV, MKV, AVI, WebM, WMV and most other formats. Output is a widely compatible MP4.
Everything runs in your browser on iPhone, Android, Windows, Mac or Chromebook. Your compressed video is clean — no logo, no intro, no outro.
Encoding happens on cloud servers, so a long 4K recording won’t freeze your laptop or drain your phone battery while it compresses.
Files are encrypted in transit and deleted automatically after processing. Download links expire after about 24 hours, and we never use your videos for anything else.
The situations where “file too large” turns into “sent”.
Free Discord uploads stop at 20 MB and Gmail attachments at 25 MB. Set the target to 19 MB or 24 MB, compress, and the clip goes through as a playable video instead of a cloud link or an error message. Need a one-click Discord preset? Open the Discord video compressor.
Messaging apps and social platforms re-compress what you upload, often harshly. Compress it yourself first with sensible settings and the version people see stays sharper — and it sends faster on mobile data.
An hour of screen recording can run to several gigabytes even though most of the frame never changes. These videos compress extremely well — often to a fraction of their size — so they upload to an LMS or shared drive in minutes.
Video compression makes a file smaller by encoding it more efficiently — mainly by lowering the bitrate (how much data each second of video uses). File size ≈ bitrate × duration, so a 60-second clip that needs to fit 19 MB can use about 2.5 Mbps in total. A few rules keep the picture looking good:
Modern encoders keep 1080p looking clean at surprisingly low bitrates. Only drop to 720p when the target size is very small for the video’s length.
H.265 (HEVC) needs roughly 30–50% less data than H.264 for similar quality. Pick H.264 when the video must play on older devices or every browser.
In quality mode, lower CRF means better quality. 21 is a good default; go above 28 only when size matters far more than detail.
Aim about 5% below a hard limit. Audio and the MP4 container add a small overhead on top of the video stream.
