11Love the idea of Video Compressor! 👏 I had a similar experience building Optimize My Image https://optimizemyimage.netlify.app/, an online image compressor with no usage limits. Sometimes the best tools are the ones that solve a simple problem really well. 🚀
Cool tool to reduce size of video without losing much of quality. ATB !

A very good option :)
Running media processing fully client-side is the right call for a free tool — I take the same approach with the image compressor in my own toolkit, since nobody wants to upload personal photos or videos to a stranger's server just to shrink a file. Question: how do you handle the FFmpeg/WASM bundle size on first load? That's the trickiest tradeoff I've found between keeping the page snappy and supporting enough codecs. Also +1 for no watermarks — that's what keeps people coming back. Congrats!

For videographers delivering client work, a clear 4K quality-versus-file-size comparison would be especially useful. It would help us choose compression settings without risking visible playback loss.

Really like the 100% private, local-processing angle — for a free tool that's the right architecture, and it's what we do as well. Video compression in-browser is genuinely hard (codecs, memory pressure, large files), so props for pulling it off without any uploads. One suggestion: a quick side-by-side quality comparison or estimated output size preview would help users pick the right compression level with more confidence. Solid launch!
I tried it with a 6-second 720p H.264 clip (534 KB). Medium at 480p brought it down to 103 KB, and I didn't see any request carrying the file while it encoded, so the local-processing claim held up for me. Two things I noticed when I inspected the output: the video came out as HEVC inside the MP4, which not every player or browser can decode, so an "H.264 for compatibility" option could save someone a confused re-send. And the Medium button promised ~134 kbps audio, but the file kept my ~60 kbps mono track, so the size estimate (about 147 KB) was higher than the result. Under-promising is nice, but the label could follow the source bitrate.
Local WebCodecs processing is the right call for privacy. We do browser-side scene detection and trimming for vertical video, and the gotchas we hit were phone MOVs with rotation metadata and variable frame rate. Does VidPackit keep 9:16 portrait clips upright and audio in sync after compression? And is Safari/Firefox support on the roadmap?
Doing the whole encode locally with WebCodecs is the right call for privacy. Two questions: what do Firefox and Safari users get, since their WebCodecs support is partial? A fallback, or a "use Chrome" message? And for a long file, say a 2-hour recording, does it encode as it streams or hold the whole file in memory?
