What it does
SquishyFile is a browser-based video compressor that runs entirely on the user's own device using WebCodecs and WebAssembly, so no file is uploaded to a server. It accepts MP4, MOV, MKV, AVI, and WebM files and always exports a widely compatible H.264 MP4. Users can choose a quality level via a slider or specify an exact target file size in megabytes, which the tool uses to calculate the required bitrate automatically.
Use cases
- Shrinking a large iPhone MOV recording to under 25MB so it can be sent as an email attachment
- Compressing a video to a platform-specific size limit such as 16MB for WhatsApp or 20MB for a free Discord account
- Reducing a 4K screen recording or long clip to the smallest watchable file size before archiving or sharing
- Compressing a video on an iPhone or Android device in Safari or Chrome without installing an app
- Processing a batch of clips to the same target size, since the target setting stays in place between files
Who it is for
- General users who occasionally need to shrink a video for a specific upload or attachment limit and do not want to install software
- iPhone and Android users who want a browser-based option without an App Store download
- People with privacy concerns who prefer their video never leave their own device during compression
- Professionals or hobbyists on locked-down or shared computers where installing desktop software is not an option
Alternatives and comparison
SquishyFile positions itself against two broad categories: upload-based online tools such as Clideo, VEED, and FreeConvert, which process files on remote servers and often restrict free use with size caps or watermarks; and desktop applications such as Handbrake, which offer more control but require installation. The main trade-off SquishyFile accepts in exchange for browser convenience and privacy is that compression speed depends entirely on the user's own hardware.
- Handbrake
- A free, open-source desktop application with deep encoder control; requires download and installation and has a steeper learning curve, but offers better quality-per-megabyte for high-volume or advanced use.
- Clideo
- An upload-based online tool; convenient and hardware-independent, but the file is sent to a remote server, and the free tier commonly imposes size caps, watermarks, or account requirements according to the page.
- VEED
- Another upload-based online editor and compressor; similar trade-offs to Clideo — processing happens on a server rather than the user's device, and free-tier restrictions apply.
- FreeConvert
- An upload-based converter and compressor listed alongside similar tools on the page; files leave the device, and free-tier limits on size or watermarks are noted as common across this category.
