What do Reddit users actually recommend?
Across the threads we read, the advice sorts into three tiers. For most people, the recommendation is HandBrake: free, open-source, runs on everything, and once you learn one slider (constant quality) plus one cap (resolution), it compresses anything. For technical users, the answer is FFmpeg with two-pass encoding — the method that computes an exact bitrate for a target file size, which is what "compress to 8MB" websites implement server-side. For people who want zero setup, the recurring name is 8mb.video, a web tool built around Discord's old 8MB free limit, now offering presets up to 2,000MB; it gets real praise and real complaints, which we break down below. A second web tool, autocompressor.net, comes up repeatedly in newer threads as a faster alternative.
What Reddit does not recommend is telling: watermark-heavy freemium converters get mocked consistently, and "just use Discord Nitro" appears as a pragmatic footnote rather than advice. The community's revealed preference is clearly for tools that process locally — the r/ffmpeg crowd says the quiet part out loud: uploading a video to the cloud to shrink it feels silly when your own CPU can do the job.
Why does Reddit recommend HandBrake so often?
HandBrake earns the default spot for the same reasons it's been a recommendation since the DVD era: it's genuinely free with no watermark, it's maintained, and it exposes exactly the two controls that matter for Discord — resolution (480p/720p) and quality (RF constant quality) — without making you understand bitrates. The comment we keep seeing, "HandBrake will try to compress to the size limit," is slightly optimistic: HandBrake has no true "hit exactly N MB" mode, so the practical workflow is encode, check the size, nudge the RF value, repeat. That loop is fine for a handful of videos and tedious beyond that, which is exactly the gap target-size tools fill.
If you compress clips weekly and enjoy having full control, take Reddit's advice and install HandBrake — it's excellent software and this page won't pretend otherwise. If you compress occasionally and want the size problem solved in one click without installing anything, that's where browser-based target-size tools come in.
What do Redditors say about online compressors like 8mb.video?
The thread record on 8mb.video is genuinely mixed, which is what makes Reddit useful here. On the positive side, it's free, simple, has been reliable for years for many users, and its name alone explains what it does — one commenter called it "my best friend before and even after the limit was extended." On the critical side, three complaints recur: large uploads are slow because your file must travel to their server and back; queue times appear when the service is busy; and there are scattered reports of corrupted or zero-byte outputs on very large sources (one user's 1.4GB clip came back as a 40-byte file). None of these complaints allege bad intent — they're the predictable costs of the upload-compress-download architecture.
The same architecture is also the privacy story people rarely spell out: when you use any server-side compressor, a full copy of your footage — voice chat, DMs on screen, whatever the clip contains — transits and briefly resides on someone else's infrastructure. Reddit users who care about that are the loudest local-tool advocates.
What does r/ffmpeg say about target-size compression?
The power-user answer is well documented: two-pass encoding. Pass one analyzes the video to build a per-frame complexity log; pass two spends your exact bitrate budget where the video needs it. With a 20MB target and a known duration, the math is fixed — total bitrate ≈ file size ÷ duration — and FFmpeg lands under the cap reliably. Thread participants describe replicating 8mb.video's behavior with a handful of flags, and several have shipped their own batch scripts to r/discordapp. This is precisely the computation BitSized automates: we read your video's duration, compute the bitrate budget for the size you picked, and encode with FFmpeg's own engine (compiled to WebAssembly) inside your browser — the same two ideas Reddit's technical crowd endorses, minus the command line and minus the upload.
Where does BitSized fit in? (Our honest position)
We built BitSized because the Reddit consensus had a gap: HandBrake's power comes with an install and a learning curve, FFmpeg comes with a command line, and web tools come with uploads. BitSized keeps the two properties Redditors actually defend — local processing and exact target sizes — and drops the two barriers. It runs in your browser via WebAssembly, so there's nothing to install and nothing uploaded; you can disconnect from the internet after the page loads and it still works. The compressor uses FFmpeg's engine under the hood, applies the same bitrate math the r/ffmpeg threads describe, and supports batch queues for clip-heavy nights.
What we won't claim: that we're faster than a native desktop app on huge files (browsers have memory limits, and very long videos take real time on any machine), or that Reddit endorses us (these threads predate us). If you're a power user, follow Reddit to HandBrake or FFmpeg happily. If you want the Reddit-endorsed approach with none of the setup, try the compressor here — it's free and there's nothing to sign up for.
The threads we read (check them yourself)
Summaries above are paraphrases in our own words. Approximate dates come from thread metadata; Reddit threads evolve, so read the current versions directly:
r/discordapp≈ December 2024
“Plz help me find a good video compressor” ↗The most-upvoted advice in this thread is HandBrake, described as the tool that “will try to compress to the size limit.” Multiple commenters suggest lowering resolution before bitrate and trimming first.
r/ffmpeg≈ December 2022
“What parameters would a site like 8mb.video use?” ↗Power users replicate target-size compression locally with two-pass FFmpeg encoding. The recurring sentiment: “feels very silly to upload something to the cloud when I could just be doing this with my own CPU.”
r/discordapp≈ June 2025
“Made a quick video compressor via FFMPEG and a batch file to compress videos to sub 10MB” ↗A user ships their own FFmpeg batch tool; the comments fill with recommendations for autocompressor.net, with several commenters preferring it over 8mb.video for speed.
r/discordapp≈ September 2025
“I got tired of slow online converters and the 8MB limit…” ↗The OP's frustration with slow cloud converters draws a familiar split: “Handbrake is great if you know what you're doing” versus one-click web tools. Local tools dominate the recommendations.
r/discordapp≈ August 2024
“high quality free mp4 video compressor” ↗8mb.video gets genuine praise — “8mb.video was my best friend before and even after the limit was extended” — alongside a real failure report (a 1.4GB input coming out as a 40-byte corrupted file) and advice that newer codecs (HEVC/AV1) compress about 50% better at the same quality.
