Compress video on your Mac without losing quality

How to compress a video on your Mac

1

Drop your video

Drag in one clip or a whole folder of videos.

2

Set quality & codec

Pick a CRF level and codec (H.264/H.265). Watch the size estimate update live.

3

Compress

Click Compress. Everything runs on your Mac.

Real control over the trade-off

CRF quality slider

0–51 scale. CRF 18–20 is visually lossless; push higher for smaller files when you need them.

Modern codecs

H.264 for compatibility, H.265/HEVC for ~50% smaller files, VP9 and AV1 for the web.

Frame-rate reduction

Drop 60 fps to 30 fps to shrink screen recordings and tutorials that don't need cinematic motion.

Size estimate first

See the projected output size before you encode, perfect for hitting an email or upload limit.

When you actually need this

Modern phones and cameras produce enormous files. A two-minute 4K clip can be over 1 GB. Most of the time you just need it small enough to send or store.

It won't fit in an email

Gmail and most providers cap attachments around 25 MB. Drop the CRF and resolution until the live size estimate fits, then send.

Upload limits and slow uploads

Discord, Slack, and form uploads reject big files or crawl. A smaller H.265 file uploads in a fraction of the time.

Screen recordings

Tutorials and demos don't need 60 fps or full resolution. Halving both can shrink a recording by 80% with no real loss.

Reclaiming disk space

Old vacation clips eating your SSD? Re-encode to H.265 and cut the file size roughly in half.

What people are
saying about Picmal

"It's a Mac-assed Mac App. Focused, customizable, flexible, well designed and super fast. 10+ times a day I need to convert a file for use on a website. Picmal makes that process a joy . My favorite conversion is taking a multipage PDF and converting each page to an individual image with one click (something even Preview can't do). "

"Picmal is an excellent way to manage file conversion and compression jobs of any size. There are other apps that accomplish something similar, but the simplicity and speed with which you can manage batch conversion and compression with Picmal sets it apart and makes it worth checking out."

" Simple and powerful is a combination that is hard to get right. Picmal nails it! I find image presets particularly useful. Set it up and then just drag and drop to resize and convert."

" I love the app! I use it 4-5 days a week for audio and image conversion as I tag and add missing album artwork to my library of 70,000 songs. After that is done, I would like to try it out with my Blu-ray collection on Plex. I truly appreciate the hard work that goes into creating and frequently updating an app such as this. All the best!"

"I use Picmal to convert images. It works perfectly . I can just leave the Picmal window open on my desktop. Whenever I want to convert an image, I drag the file onto the window and click “convert”—and seconds later, the converted file is in the appropriate folder with the suffix “converted.” It couldn’t be easier or more hassle-free!"

Frequently Asked Questions

How do I compress a video on my Mac?

Open Picmal, drag your video in (or a whole folder), pick a quality level and codec, and click Compress. A live size estimate shows how small it will be before you export, and everything runs on your Mac with no upload.

How much can Picmal shrink a video?

It depends on the source and your settings, but 50–80% is common. Switching to H.265 (HEVC) alone cuts size roughly in half versus H.264 at the same quality, and lowering the CRF, resolution, or frame rate shrinks it further.

Does compressing a video lose quality?

Only as much as you choose. Picmal uses a CRF quality slider. At CRF 18–20 the result is visually lossless. Picmal also shows an estimated output size before you encode, so you can dial in the size/quality trade-off without guessing.

Can I compress a video to send by email?

Yes. Most email providers cap attachments around 25 MB. Lower the CRF, drop the resolution, or reduce the frame rate and watch the live size estimate until your clip fits, then export.

Which video formats can Picmal compress?

MP4, MOV, MKV, AVI, WebM, M4V, MPG, HEVC, FLV, WMV, 3GP, M2TS/MTS, VOB, TS and more. You can keep the same container or switch it while compressing.

Can I batch compress multiple videos?

Yes. Drop multiple videos or a whole folder into Picmal and compress them all with the same settings in one pass.

Is there an upload, watermark, or size limit?

No. Picmal compresses entirely on your Mac. No uploads, no queues, no watermark, and no file-size cap. It's a one-time $15.99, not a subscription.
