1Upload the AVI videos you want resized — work from the largest original you have rather than from a copy you already shrank once.
2Set the new size: for an image, a width and height in pixels with an optional aspect-ratio lock; for a video, one of the preset sizes from 1920x1080 down to 640x360.
3Start the resize; the picture is scaled to the size you chose.
4Download the resized AVI file.
Resize AVI FAQ
Does the source format affect the result of a resize?
+
It does. AVI is the 1992 Microsoft container: broad codec support but no modern streaming features, no B-frame-friendly indexing and poor subtitle handling. 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 AVI I should watch for?
+
Yes — AVI has no modern index or B-frame-friendly structure, so accurate seeking usually requires a real re-encode rather than a copy. Worth checking before you resize a file you will not be able to regenerate.
What is the most common mistake when resizing AVI 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.
Can I run Resize AVI on several AVI videos at once?
+
Yes. Uploads queue in parallel, which matters more here than anywhere else because video jobs are minutes rather than seconds. Free accounts run one file at a time; a pass lifts that.
Is there a file size limit on Resize AVI?
+
Yes: free accounts process video up to 40 MB per file, by far the most generous cap on the site; ffmpeg with x264, x265 and libvpx does the work, which is the same toolchain behind most desktop video software. Video is the one family where the cap is high enough that upload time, not the limit, is what you will actually notice.
Why does a Word site host Resize AVI?
+
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 AVI shares the upload, the caps and the account with the conversions for that reason.
What should I do with the result once Resize AVI 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 AVI 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 is needed. Uploads and results are kept for about 24 hours, which leaves time to download the result, and are then deleted automatically; nobody reads, lists or indexes them. Several files in one job need a paid plan.
