1Upload the videos you want resized — work from the largest original you have rather than from a copy you already shrank once.
2Type a target width, a target height or a percentage, and leave the aspect-ratio lock on unless you deliberately want stretching.
3Run the resize; every file in the batch is taken to the same target in a single pass.
4Download the resized Video file, or the whole set together as one archive.
Resize Video FAQ
Does the source format affect the result of a resize?
+
It does. this format is read and written by the same streaming pipeline as everything else we support. That is what decides whether shrinking the file is purely a question of pixels or also a question of re-encoding.
Is there anything specific to Video I should watch for?
+
Yes — the container and codec are probed before anything runs, so mixed uploads in one batch are handled per file. Worth checking before you resize a file you will not be able to regenerate.
What is the most common mistake when resizing videos?
+
Upscaling. Enlarging cannot invent detail that was never captured, so the result is a soft version of the original at a bigger size. Always resize down from the largest source you have, and resize once rather than in stages.
How does Resize Video change the dimensions?
+
Concretely, each clip is probed for its real resolution first, then scaled and re-encoded, so a batch of mixed sources lands on one target size rather than one scale factor. You give it a target width, a target height or a percentage, and it works from the original rather than from a previously resized copy.
Can I run Resize Video on several videos at once?
+
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.
What happens to audio, subtitle and chapter tracks?
+
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.
Is there a file size limit on Resize Video?
+
Yes: free accounts process video up to 40 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.
Will Resize Video lower the quality of my videos?
+
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.
Why does a Word site host Resize Video?
+
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. Resize Video shares the upload, the caps and the account with the conversions for that reason.
What should I do with the result once Resize Video is finished?
+
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.
Is Resize Video here the same tool the sibling sites run?
+
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.
Do I need an account, and does anything get kept?
+
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.
