Bigger files take longer — your CPU does the work, privately.
No upload limit, because there’s no upload
Cloud compressors cap how big a file you can upload — and uploading a multi-gigabyte video is slow and a privacy risk. Here the work happens on your own device, so the only real limit is your computer’s memory, not an arbitrary upload cap.
For very large files, use a desktop browser with plenty of free RAM, close other heavy tabs, and consider the 1080p (YouTube) preset to downscale 4K — that alone can cut size by half or more.
If a giant file fails
Browsers limit how much memory a page can use, so extremely large clips can fail on low-memory devices. If that happens, trim the video to a shorter section, lower the resolution, or split it into parts — each part compresses independently.
Frequently asked questions
How do I compress a 1 GB or 2 GB video for free?
Drop it in and set a target size. Because compression runs on your device, there’s no upload limit — though very large files need a capable computer with free memory.
Why might a very large file fail?
Browsers cap per-page memory. On low-RAM devices a multi-gigabyte clip can exceed that. Use a desktop, downscale to 1080p, or split the video into parts.
Is it faster than online uploaders for big files?
Often yes — you skip the slow upload entirely. Compression speed then depends on your CPU.
Is my large file private?
Yes — it’s never uploaded. The whole process happens in your browser.
