Squishr
Guaranteed Under the Limit · 100% On-Device
Drop a video.
Make it fit.
Tap a target — Discord's 10 MB, WhatsApp's 16 MB, email's 20 MB, or any size you type — and Squishr compresses your video to a file that is guaranteed to land under the limit. Entirely on your Mac. Nothing is ever uploaded. Available in 13 languages.

See it in action
Pick a target. Squishr works out the bitrate, encodes, then checks the real byte size.
How it works
Three steps, then it fits.
Drop in your video
Drop any video onto the window — or a whole folder for a batch. A filmstrip appears with the real duration and size, ready to trim if you want.
Tap a target
Discord — 10 MB, WhatsApp — 16 MB, Gmail — 25 MB, iMessage — 100 MB, Telegram — 2 GB, or type any size. An honest quality meter shows how it will look before you wait — with one-tap fixes if the target is tight.
Compress
Squishr computes the exact bitrate from the real duration, encodes on Apple hardware, verifies the actual byte size, and automatically re-encodes smaller if needed. The file always fits — and your original is never touched.
Features
Never a 10.2 MB failed upload again.
One focused, native window that does the math other tools won't — without ever sending your video to the cloud.
Guaranteed to fit
Squishr computes the exact bitrate from your video's real duration, encodes, then verifies the actual byte size of the output — and automatically re-encodes smaller if it's over, with a two-pass precision fallback. The file always lands under the limit.
Verified byte size
Copy, then paste the file
When the squish finishes, hit Copy and the whole video file lands on your clipboard. Paste it straight into Messages, Discord, Mail, or a Finder window — no hunting down the export, no dragging across three windows.
Paste anywhere
An honest quality meter
Before you wait for an encode, a meter predicts how the video will look at that size — Great, Decent, or Rough — with one-tap fixes: drop to 720p, cap 30 fps, shrink the audio, or trim it shorter.
Before encoding
Trim on a filmstrip
Drag handles on a filmstrip to keep just the moment, or type the exact in and out times when dragging isn't precise enough. A shorter clip means dramatically better quality at the same target — the meter and size estimate update live.
Batch everything
Drop any number of videos — or a whole folder, subfolders and all, in reading order — and compress them to one target, with per-file progress and results. Sort the queue by name, size, length, status or how much each one saved. Every row has its own stop button, so a long encode can be ended without stopping everything queued behind it, and every row can show its original in Finder — including one that failed, which is exactly when you want to go and look at the file. When the queue spans more than one folder, each row says which folder it came from.
Presets for real limits
Discord — 10 MB, WhatsApp — 16 MB, Email — 20 MB, Gmail — 25 MB, Discord Nitro Basic — 50 MB, iMessage — 100 MB, Signal — 100 MB, Nitro — 500 MB, Telegram — 2 GB, or any custom size you type. Targets use the strictest interpretation of each cap, so uploads never bounce.
The hard files work
Rotated iPhone portrait video stays portrait. HDR is tone-mapped properly so colors don't wash out. 120 fps screen recordings get capped when the budget is tight, 5.1 surround is downmixed, GIFs become tiny MP4s, and variable-frame-rate captures keep their timing.

Apple hardware speed
Encoding runs on Apple VideoToolbox hardware, so most videos compress in a fraction of their runtime. Output is a standard MP4 (H.264 + AAC, faststart) that plays everywhere — with HEVC and AV1 there when you want a smaller file.
VideoToolbox
Pick your trade
Faster, Balanced, or Best quality — which goes straight to two-pass encoding for the most picture per byte, and says up front that it will take longer. Choose AV1 and a long video holds together at a size where H.264 falls apart; Squishr tells you plainly that it is slow and worth checking playback first.
H.264 · HEVC · AV1
Honest progress
The progress bar tracks the real encode from the first frame to the last — no leaping to 99% and hanging there — and tells you how long is left, for the video in front of you and for the whole batch. When it says almost done, it's almost done.
Non-destructive
Your originals are never modified. Every compress writes a new file ("clip — Discord.mp4") next to the original or into a folder you choose, and existing files are never overwritten — there is no Replace switch to turn on, and no output can take the name of a video sitting in your queue. Stopping a compress leaves the folder exactly as it found it, even if you stop it on the very last step.
Originals untouched
Unlimited, no strings
No watermarks, no daily caps, no queues, no file-size ceilings on input. Compress as many videos as you like, forever, for free.
100% on your Mac
Nothing is uploaded — ever. No account, no cloud, no telemetry. Web compressors make you upload your video to someone else's server; Squishr never does.

13 languages, built in
Squishr speaks 13 languages out of the box — German, English, Spanish, French, Italian, Japanese, Korean, Dutch, Polish, Brazilian Portuguese, Russian, Turkish and Simplified Chinese. It auto-detects your Mac's system language on first launch, or pick one yourself anytime from the in-app flag picker; the whole window follows, sheets and row labels included.
13 languages
Automatic update checks
Squishr quietly checks about once a week and badges the update button when a newer version is ready — never a pop-up, and nothing downloads or installs automatically. Turn it off anytime.

FAQ
Common questions.
Is Squishr really free?
Personal use is free forever — unlimited files, no account, no trial timer, no watermarks. If you use Squishr at work, a one-time $5 business license per computer keeps it supported.
How is the file guaranteed to fit?
Squishr computes the exact bitrate for your target from the video's real duration, encodes with Apple VideoToolbox hardware, then verifies the actual byte size of the output. If it's over the limit, Squishr automatically re-encodes smaller — falling back to two-pass x264 precision encoding when needed. The file always lands under the limit; you'll never see a 10.2 MB "failed to upload" again.
How does the business license work?
If you use Squishr commercially, buy a one-time $5 license per computer from the pricing section — secure checkout via Stripe, and your license key is emailed instantly. The personal tier is the full app with no nag screens, so you can evaluate it freely first.
Does Squishr upload my videos anywhere?
No. Every compress runs entirely on your Mac — nothing you open or export is ever uploaded, and there's no account and no telemetry. The only time Squishr contacts our server is if you enter a business license key (to validate it) or click Check for Updates (which sends only the app version). Your video is never involved.
Will it change my original files?
Never. Squishr is non-destructive by design: every compress writes a new file ("clip — Discord.mp4") next to your original or into a folder you choose. Existing files are never overwritten — Squishr picks a unique name instead.
What if my video will look bad at 10 MB?
Squishr tells you before you wait. A quality meter predicts how the video will look at that size — Great, Decent, Rough, or Won't look good — and offers one-tap fixes: drop to 720p, cap 30 fps, shrink or drop the audio, or trim to the moment that matters. A shorter clip is the biggest quality win of all.
What formats can it read and write?
In: almost any video — MOV, MP4, MKV, WebM, AVI, even GIFs (which become tiny MP4s). Out: a standard MP4 (H.264 + AAC, faststart) that plays everywhere Discord, WhatsApp and email do — with HEVC and AV1 available as opt-ins where smaller files matter more than universal playback. AV1 holds a watchable picture at sizes where H.264 falls apart, but no Mac encodes it in hardware, so it is much slower; Squishr says so before you start, and reminds you to check that wherever you are posting can play it.
Why 10 MB for Discord?
Discord cut free uploads from 25 MB to 10 MB, and the cap is enforced in bytes — a "10.2 MB" file bounces. Squishr's Discord preset targets the strictest interpretation of the limit and verifies the real byte size, so the upload always goes through. Nitro Basic (50 MB) and Nitro (500 MB) presets are included too.
Will macOS warn me about an unidentified developer?
No. Squishr is signed with an Apple Developer ID and notarized by Apple, so it opens with a normal double-click the first time — no Open Anyway dance, no Terminal.
How do I update Squishr?
Squishr updates itself. It checks about once a week and, when a new version is out, shows you what changed and offers to install it in place — the download is signature-checked, and one that doesn't verify is refused. You can also check on demand, turn the automatic check off in the update panel, or download the DMG from this page and drag it into Applications yourself. Your preferences carry over.
Is there a Windows version?
Not yet — Squishr is Mac-only for now. It's built as a native Mac app from the ground up, window to encoder.
