About this tool

Reduce file sizes by up to 90% — free online compressor for images, video and audio.

Large files slow down websites, fill up storage, and take forever to share. FlipFileZone's free compressor uses industry-standard codecs to reduce file sizes dramatically while keeping the output looking and sounding great. No software to install — just upload, compress, and download.

Frequently asked questions

How much can I reduce a PNG file?

PNG files often compress 40-70% depending on content. Photos with gradients compress more than flat-colour graphics.

Will compression make my image blurry?

At 80%+ quality, the difference is invisible to the human eye. Only very low quality settings produce visible artefacts.

Can I compress a video without re-encoding?

Re-encoding is required to reduce video file size. We use H.264 and H.265 codecs at optimised bitrates.

Is there a file size limit for compression?

No enforced limit. Large video files may take a few minutes but will complete successfully.

Does compressing audio reduce quality?

At 192 kbps MP3 or higher, the quality difference from uncompressed audio is inaudible on standard speakers and headphones.
