Frequently Asked Questions
Is FileCompressor free?
Yes. Every tool is free with no sign up, no watermark and no file limit.
Are my files uploaded?
No. Compression runs in your browser using your own device, so files are never uploaded, stored or shared.
How do I compress an image to 100KB or 50KB?
Open the Compress Image to 100KB or 50KB tool, add your photo and download the result. It keeps the best quality that fits the size limit.
Can I compress videos and audio too?
Yes. The video tools re-encode MP4, MOV, WebM, MKV and AVI to smaller H.264 MP4, and the audio tools turn MP3, WAV, M4A, FLAC and OGG into compact MP3, all inside your browser.
Which formats are supported?
JPG, PNG, WebP, GIF and BMP images, MP4, MOV, WebM, MKV and AVI videos, MP3, WAV, M4A, FLAC and OGG audio, PDF documents, and any file type for ZIP archives.
