Every common batch compression need, covered
Batch compression is more than just picking a few extra files. Here are the specific needs users ask about most.
Batch compress by file count
Pick a handful or dozens of videos — there is no fixed count limit. The tool compresses each file in sequence, so there is no need to repeat the process.
Keeps original file names for easy matching
Compressed files keep their original names (only the extension changes), so they map one-to-one to your source assets instead of getting hard-to-read random names.
How multi-folder assets are handled
Due to browser security limits, web tools cannot read or recreate your local folder hierarchy. If assets are spread across several subfolders, upload and compress folder by folder, then move the results back into place.
Compress to a target size or bitrate
Batch mode offers preset compression levels mapped to target bitrate ranges, applied to every file. To set an exact target size or bitrate for a single video, switch to the single-file compressor.
Batch compress your phone photo gallery
Works in iOS Safari 16+ and Android Chrome — multi-select videos in your phone gallery and upload them directly for batch compression, no app needed.
Batch compression that keeps quality intact
The compression algorithm allocates bitrate intelligently, keeping visual quality as high as possible while shrinking size. For higher quality needs, choose a lighter compression level or test with a small batch first.
Batch compress MP4, MOV, WebM and MKV together
Videos in different formats can be mixed in the same batch — the tool detects each one and outputs uniformly to MP4 or WebM, no manual conversion needed first.
Error isolation — one failure will not stop the rest
If a file fails to compress due to an encoding issue, the system keeps processing the rest of the queue. Once done, you can review the results and retry the failed file on its own.
Free up device storage
Compress an entire album or asset folder at once and free up 40%-70% of storage on average — great for clearing out a backlog of videos on your phone or computer.
Batch compression vs single-file compression: which one?
Both tools share the same compression engine — the difference is how files are processed and how fine-grained the settings are. Pick the one that fits your scenario below.
| Tool | Setting granularity | Best Use Case |
|---|---|---|
| Batch compression (this tool) | Applies one compression level to all files | Large sets of assets that need the same treatment, such as organizing an album, archiving shoot footage in bulk, or compressing a batch of course or training videos. |
| Single-file compression | Lets you adjust the compression level and settings per video | When each video has different quality requirements, or you need to fine-tune one important file, processing them individually gives you more control. |
Common use cases for batch video compression
Compress a full season of footage or archive of past work at once, saving storage while making it easy to package and share with clients or collaborators.
Straight-off-camera 4K footage takes up huge amounts of space; batch compressing before archiving significantly improves how efficiently you use your drives and external storage.
Compress a batch of training or meeting recordings down to a size suited for online distribution, easing storage and bandwidth pressure on internal drives and learning platforms.
Phone gallery full of videos you cannot bear to delete? Batch compress and re-save them to free up a large amount of storage without losing the content.
Cloud storage is usually billed by capacity — batch compressing before uploading directly cuts the paid space you use and the upload time.
Batch compress all your footage before importing it into editing software to shrink project file size, reduce lag on your device, and make it easier to move assets between devices.
Supported Video Formats

About Batch Compression
The batch video compressor processes multiple video files at once, using smart compression algorithms to dramatically reduce file size while preserving good visual quality. It's ideal for scenarios where you need to handle lots of video files.
Batch compression is especially useful for clearing out large numbers of video files — on average it saves 50% or more storage space. The effect is even more noticeable on high-definition footage, effectively solving tight storage problems.

Frequently Asked Questions
How much space can batch compression save?
Depending on the video type and compression level, you can typically save 40%-70% of storage space. Results are especially noticeable with HD video.
How is quality preserved after compression?
We use advanced compression algorithms that intelligently allocate bitrate, shrinking file size while keeping visual quality as high as possible. You can choose the compression level that fits your needs.
How many files can I compress at once?
There's no hard limit, but it's best to match your device's capabilities. We generally recommend 5-15 files at a time to avoid tying up your system for too long.
What if a file fails during compression?
If one file fails, the system will continue processing the rest and show an error message. Once compression is done, you can review the detailed results.
Are file names and folder structure preserved after batch compression?
File names are preserved (only the extension changes) so you can match them to the originals. Because of browser security limits, the tool cannot detect or recreate your local folder hierarchy. For assets spread across multiple subfolders, upload and compress them folder by folder.
Can I batch compress any number of files?
Yes, there is no fixed file count limit. Whether you pick a handful or dozens of videos is entirely up to you, and the tool processes them in sequence. For a smoother experience, keep the batch size reasonable based on your device memory.
Can I batch compress to a specific file size or bitrate?
Batch mode offers several preset compression levels, each mapped to a target bitrate range, applied uniformly to all files. It does not yet support setting an exact target size per file. If you need a precise bitrate for a single video, use the single-file compressor instead.
Can I batch compress videos from my phone gallery?
Yes. The tool works in mobile browsers (iOS Safari 16+ and Android Chrome) — multi-select videos in your phone gallery and upload them directly for batch compression, no app required. When compressing large batches on a phone, memory is limited, so choose fewer files at a time or process in smaller batches.
Which video formats does batch compression support?
Reads MP4, WebM, MOV, MKV, AVI and other common formats, and outputs uniformly to MP4 or WebM. Files of different formats can be mixed in the same batch.
What is the difference between batch compression and single-file compression?
Single-file compression lets you fine-tune settings for one video (e.g. a custom compression level per file). Batch compression applies the same level to many files at once, ideal when a large set of assets needs the same treatment.
Does batch compression upload files to a server?
No. All compression happens locally in your browser — files never leave your device, fully protecting your privacy and unaffected by upload speed.
Does batch compression require payment or sign-up?
It's completely free, with no account, watermark, or usage limits. Just open the page and start — all processing happens locally and uses no server resources.
