100% offline · No upload · Free for 8 files/day

The problem with cloud tools

Online and cloud-based alternatives come with real trade-offs.

Tiny upload size limits

Online video compressors cap free uploads at a few hundred megabytes. A single phone clip or screen recording can blow past the limit before you even start.

Painfully slow uploads

You spend more time pushing a multi-gigabyte file up to a server than the compression itself takes. On slow or metered connections it is simply not practical.

Your footage sits on a server

Whatever you upload — unreleased content, recordings of meetings, personal videos — is processed and temporarily stored by a third party you have to trust.

Compress video on your own hardware, at full size

  • Compress MP4, MOV, AVI and MKV with no upload size limit
  • Convert between formats and codecs without re-uploading
  • Trim, split and merge clips to cut size before compressing
  • Control resolution, bitrate and frame rate for the size you need
  • Batch-compress a whole folder of videos in one run
  • Extract or remove audio, and generate thumbnails locally

What you can do

Built for video compressor that stays on your machine.

No size limit

Compress multi-gigabyte recordings that online tools reject — there is no upload cap when it runs locally.

Convert formats

Move between MP4, MOV, AVI and MKV, or turn clips into GIFs, without sending files anywhere.

Trim & split

Cut footage to the part you need and split long videos into segments to shrink size fast.

Tune quality

Dial in resolution, bitrate and frame rate so you hit a target file size without ruining clarity.

Batch compress

Queue an entire folder of videos and compress them all with one consistent setting.

Fully offline

No uploads, no waiting on a server — compression uses your machine and works without internet.

Frequently asked questions

Is there a file-size limit when compressing video?

No. Because compression runs on your own computer, there is no upload cap. You can compress multi-gigabyte recordings that online compressors would reject outright.

Which video formats are supported?

1FileTool works with MP4, MOV, AVI and MKV and can convert between them. You can also convert clips to GIF, extract or remove audio, and adjust resolution, bitrate and frame rate.

How is this better than an online video compressor?

Online tools force you to upload your footage and limit free file sizes. 1FileTool processes everything locally, so it is faster on large files, has no size limit, and your video never leaves your device.

Can I compress many videos at once?

Yes. The Batch Compress tool queues an entire folder of videos and processes them with the same settings, which is ideal for shrinking a backlog of recordings.

Is it free and offline?

All 25 video tools run 100% offline and are free for up to 8 files per day. Pro is a one-time purchase from $29 for unlimited compression.
