Every platform in one pass
A macOS .icns, a Windows .ico, and an iOS .appiconset from the same source, all sizes rendered for you.
Drops straight into Xcode
The .appiconset comes with its Contents.json and every required size, ready for your asset catalog. iOS icons flattened to opaque, per App Store rules.
Handles any source
Non-square art fits without cropping. Pick a Big Sur squircle, Tahoe, or None for the macOS tile shape.

From the people
who use it
"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)."
"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!"
"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!"
"Working on a presentation and had to convert and resize a lot of images. Picmal did them all in a flash."
"I feel Picmal is one of the apps that I would categorize as essential. There are many features that distinguish the app from other web converters such as Folder Watching and Clipboard Optimization."
"Clean and easy to use. Perfect for quickly converting images without unnecessary extras."
"Everything works as expected - great app!"
"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."
"I f* love this app. Just so you know. Keep building!"
"I like the interface. I like the batch processing. I like the fact in the I can set default conversions. I like your program a lot."
"I like the quality of the image processing. It also supports all the important image files. But it still needs some work regarding both the UI and the UX design of it."
"I love how Picmal's made compressing videos a frictionless, easy and straightforward."
"It's simple to use and does everything I need it to do. Hell, it does much more than I need and the developer keeps adding features :)"
"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!"
"The program is very simple and practical, and its options are clear."
"Thoughtful, polished, and constantly improving. Alberto genuinely listens to feedback, and it shows in Picmal. Easy 5 stars."
"Picmal is simple and fast but also integrates complex workloads if needed."
"Picmal is complete. The quality is good, and it does exactly what I need."
"Easy to use, automation & batch processing. AVIF & Webp support"
"keep up the great work! Very cool tool you've built here."
"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."
"Me ha sosprendido la compresion que realiza el programa y si apreciar la calidad."
"The easy going workflow"
"I just sent a few samples through to check everything, and I am very pleased with the results. Everything worked correctly and above all it was easy and not unduly complicated."

How does the license work?
You pay once and keep it. No renewals, no subscriptions. Your license activates on the number of Macs you bought it for, and you can move it to another Mac whenever you want. Prices are in USD, tax is added at checkout, and you pay through Stripe.
I bought Picmal and now I need more Macs. Can I upgrade?
Yes, and you only pay the difference. Going from 1 Mac to 2 is $10, 2 to 5 is $50, 5 to 10 is $60, and every other jump works the same way. Enter your license key here and the same key covers more Macs. The offer never expires, so starting small is never the wrong call.
What happens if I get a new Mac?
Open Picmal on your old Mac, go to Picmal → Register license to deactivate, then activate on the new one. Takes about ten seconds.
Do you offer student or country discounts?
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.

How do I generate an app icon on my Mac?
Drop your source image into Picmal, pick App Icons as the output, choose the platforms you want, and click go. Picmal renders every size and packages them for you.
What formats do I get out?
A macOS .icns file, a Windows .ico file, and an iOS .appiconset folder. You can generate one platform or all three at once from the same source image, so a single render covers your Mac app, your Windows build, and your iOS project.
Can I use the iOS set directly in Xcode?
Yes. Picmal writes a proper .appiconset folder with the Contents.json and every required size, so you drop it straight into your Xcode asset catalog and it's ready to build. The iOS icons are flattened to opaque with no alpha channel, which is what the App Store requires.
What if my source image isn't square?
Picmal fits a non-square image into each icon without cropping it, so nothing important gets cut off at the edges. For the cleanest result, start from a square image at the highest resolution you have, ideally 1024x1024 or larger.
Can I change the macOS icon tile shape?
Yes. Pick the Big Sur squircle for the classic rounded-square macOS tile, Tahoe for the newer shape, or None if you want to keep your full-bleed artwork and mask it yourself. Windows .ico and iOS icons keep their own platform conventions.
Can I generate icons from Shortcuts or the command line?
Yes. Picmal ships a Shortcuts action so you can wire icon generation into an automation, and a command-line tool so you can script it into a build step. Point either at a source image and get the same icon set the app produces.
Do my images stay private, and what does it cost?
Everything happens locally on your Mac. Your source art never gets uploaded, there are no per-file limits, and nothing leaves your machine. It's a one-time $29, not a subscription, updates included.
