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)."

"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!"

River Sloane, Picmal user

"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!"

"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 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!"

Is Picmal a good Kompressor alternative?

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.

Does Picmal have real-time preview like Kompressor?

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 useful.

Why pay for Picmal when Kompressor is free?

Kompressor is free and does images only. Picmal is $29 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.

Can Kompressor convert video files?

No. Kompressor does images only. For video, audio, or format conversion, Picmal handles those.

What if Picmal doesn't work for me?

Email support@picmal.app within 14 days and I'll refund you in full, no questions asked.
