How to Compress Video

1 Drop your videos into the box above, or pick them from your device — there is nothing to install and no account to create.
2 Choose how hard to squeeze: a quality or bitrate target, and optionally smaller dimensions if size matters more to you than detail.
3 Start the job and let the workers re-pack the file; your original is never modified in place.
4 Compare the new size against the original, then download the compressed Video file.

Compress Video FAQ

Does the format of my file change how much I can save?
+
Very much so. this format is read and written by the same streaming pipeline as everything else we support. That determines both the headroom available and whether the saving costs you anything in fidelity.
Yes — the container and codec are probed before anything runs, so mixed uploads in one batch are handled per file. It is worth knowing before you overwrite an original you might need again.
Compressing the same file repeatedly. Each pass on a lossy format is a fresh generation of loss and the savings shrink while the damage accumulates. Go from the original to your target in one step, and keep the original.
Concretely, each file is probed first, then re-encoded at the CRF you set with the picture optionally scaled, so a mixed batch of containers is handled per file rather than assumed uniform. Nothing about it depends on you installing software: the job runs server-side and hands back a finished file.
Yes, and it matters here more than anywhere else — video jobs run in minutes, so queueing the batch in parallel is the difference between one wait and several.
They are carried across wherever the target container can hold them, including multiple audio languages, embedded subtitles and chapter markers, rather than silently keeping only the first track of each.
Yes: free accounts process video up to 500 MB per file whichever container you brought; ffmpeg with x264, x265 and libvpx does the encoding. It is high enough that upload speed is usually the binding constraint rather than the cap itself.
Only if the operation requires re-drawing frames. Container-level and timeline-level work is done as a stream copy, which is bit-identical to the source and finishes in seconds. Anything that must re-encode does so at a quality level you choose.
WORD.to is built around the editable end of a document's life — the DOCX that is still being written, still being styled and still being argued over, before anyone flattens it for sending. Office files are containers full of other people's media — images, embedded audio, fonts — so the work people need on them is usually the work they would need on those contents anyway. Compress Video shares the upload, the caps and the account with the conversions for that reason.
The converter on this site takes documents out to PDF for sending, to images for embedding and to plain text for anything that has to read them programmatically, and back the other way. Doing that afterwards keeps the editable original around, which is the part you cannot get back once it has been flattened.
The engines are shared — the same document toolchain, the same workers, the same limits. What a Word site adds is a view on what survives leaving the Office format and what does not, which is the question every one of these jobs actually turns on. It also starts from one fact about the format this site is named after: the document is a zip of XML, so text edits are cheap and the weight is almost always the embedded images.
No account, and nothing is kept: uploads are deleted from the workers shortly after the job finishes, nothing is read and nothing is indexed. Free accounts exist for history and batch size, not for access.
