Make heavy videos light enough to send, and never bigger than the original
Drop an MP4, MOV, or WebM up to 100MB. It is processed in your browser.
Drag the timeline handles to keep the best part, then set the size, filter, mosaic, or volume if you like.
Choose messenger, social media, or high quality, check the estimated size, and download.
Messengers and email limit attachments, and big videos are slow to send and upload. Prezll re-encodes your video in the browser at a lower bitrate and resolution, then checks the result against the original so the file never gets bigger. Trim unneeded parts, fit social media sizes, and hide faces or license plates with mosaic or blur along the way. Nothing is uploaded.
No. Everything runs in your browser, so your video never leaves your device.
No. Prezll checks the final size and re-encodes at a lower setting if needed, so the saved file is always smaller than the original.
Up to 100MB per video. Very large or high-resolution videos can be slow on phones, so try a computer if one fails.
