Kompressor compresses images, for free, and does it well. If you also need to convert formats, work with video and audio, or handle PDFs, and you want Shortcuts and folder monitoring, Picmal covers all of it. Everything runs on your Mac.
Kompressor is a free Mac image compressor with a live quality preview for each file. Picmal costs $39 once and does more. It converts and compresses images, video, audio, and PDFs, with Shortcuts, folder monitoring, and Finder right-click.
Both run offline on your Mac. Kompressor does one thing, compressing images with a live quality preview. Picmal does more: convert, compress, and edit across images, video, audio, and PDFs.

More than image compression
Free, images only, with a live quality preview
One app for images, video, audio, and PDFs. Convert, compress, and edit, all on your Mac. These are the essentials, and there's plenty more in the docs.
Over 100 formats across images, video, audio, RAW, and PDF. HEIC to JPG, MOV to MP4, FLAC to ALAC. Drop it in, pick the output, done.
Get under an email limit or a slow upload, without the quality drop you'd actually notice. No browser, no waiting.
Break a PDF apart, or drag pages around to reorder, rotate, and delete. Your documents never leave your Mac.
Stitch a pile of clips into one video. Drag to reorder, pick the format, export in a single pass.
Join tracks into one file, or split a long recording by its chapters. Podcasts and audiobooks, sorted.
Turn a folder of photos into a multi-page PDF. A4, Letter, or custom, with a password if you want one.
Merge a stack of PDFs into one file. Put the pages in the right order, set the size, and save it out.
Finder, Shortcuts, and Raycast. A conversion is never more than a right-click away.
Script it, drop it in a cron job, or hand it to a coding agent. The same engine as the app, right from your terminal.
"Clean and easy to use. Perfect for quickly converting images without unnecessary extras."
"Everything works as expected - great app!"
"Great app! Simple and easy to use."
"It works perfectly now! Thanks and good work. It's really the kind of utility that I find very useful. I know that there are tons of free online tools doing the same thing but it's so much faster that way."
"Wonderfully simple app! I struggled with converting my images from one format to another constantly with online free tools. Picmal makes it effortless. Worth the money to avoid the hassle for sure!"
"You did a great job here! I like how easy Picmal is to use, and the frequent upgrades show that you are very committed to improving this beautiful software."
"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)."
"I really like these kinds of tools: simple interface, focused functions, one-time purchase, and continuous updates."
"Been enjoying the app! Thanks for the very handy utility."
"I f* love this app. Just so you know. Keep building!"

You pay once and keep it. No renewals, no subscriptions. Picmal activates on 2 Macs, Picmal Pro on 5, and you can move a license to another Mac whenever you want.
The app is identical, and so is the support: one person answers every email, and that person is me. Pro covers 5 Macs instead of 2.
Yes, and you only pay the difference: $30 takes Picmal to Pro, and older 1-Mac licenses have their own prices. Enter your license key here and the same key covers more Macs. The offer never expires, so starting with the cheaper plan is never the wrong call.
Same price, same engines, same quality. Apple handles the purchase, updates and refunds, and you get Family Sharing with no license key. Buying direct adds the command line tool, the Raycast extension, watched folders, camera EXIF on RAW conversions, and up to 5 Macs on one license. Here is the full comparison of the two builds.
Open Picmal on your old Mac, go to Picmal → Register license to deactivate, then activate on the new one. Takes about ten seconds.
Yes. I want Picmal to be affordable wherever you are. Students and educators get 40% off: verify your school email on the education page and the code lands in your inbox. If the price is steep for your country, checkout already adjusts it for you. If it still doesn't work, email support@picmal.app and tell me where you are, and I'll send a code.

Hello there 👋
I'm Alberto, the developer behind Picmal.
Picmal started because I was tired of opening a browser every time I needed to convert a few files. I figured there had to be a better way, so I built one.
Over time, that simple image converter has grown into something much bigger, mostly thanks to the people who use it.
Along the way, I've tried to stay true to a few simple ideas: your files should stay on your computer, the app should feel at home on your Mac, and you should only have to pay once.
One of my favorite parts of building Picmal is talking to customers. Many of the features in the app today started as conversations with people who needed something that didn't exist yet.
So if there's a feature you've always wished for, or something you haven't found in other tools, I'd love to hear from you. If it fits Picmal, I'll do my best to build it.
Best,
Alberto

If you need more than image compression, yes. Picmal converts and compresses images, video, audio, and PDFs in one app, with Shortcuts, folder monitoring, and Finder right-click. If images are all you need, Kompressor is free and does that well.
No. Picmal batches files without a per-file preview. If you want to see the before and after for each image before committing, Kompressor's live preview is genuinely useful.
Kompressor is free and does images only. Picmal is $39 and covers video, audio, and PDFs alongside images. It also converts formats, strips metadata, and works with Shortcuts and folder monitoring. If image compression is all you need, Kompressor is a fine choice.
No. Kompressor does images only. For video, audio, or format conversion, Picmal handles those.
