What people are
saying about Picmal

"Clean and easy to use. Perfect for quickly converting images without unnecessary extras."

Marynes

"Everything works as expected - great app!"

Anthony Nguyen

"Great app! Simple and easy to use."

Beckett R

"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."

7107Labs

"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

"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."

Gianluca Savini

"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."

"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."

Charles Willson

"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."

Yiannis

"I love how Picmal's made compressing videos a frictionless, easy and straightforward."

George

"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 :)"

Adam L

"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!"

Trevor

"The program is very simple and practical, and its options are clear."

Abadi

"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!"

Marie-Theres

"Thoughtful, polished, and constantly improving. Alberto genuinely listens to feedback, and it shows in Picmal. Easy 5 stars."

Daniel Hewitt

"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."

Joel

"Picmal is simple and fast but also integrates complex workloads if needed."

Prices in USD. Any tax is added at checkout. Secure payment via Stripe.

How does the license work?

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.

What is the difference between Picmal and Picmal Pro?

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.

I bought Picmal and now I need more Macs. Can I upgrade?

Yes, for $30. Email support@picmal.app and I'll send you the link, then your existing key covers 5 Macs. The offer never expires, so starting with the cheaper plan is never the wrong call.

Should I buy here or on the Mac App Store?

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.

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.

Can I get a refund?

14 days, no questions asked. Email support@picmal.app. App Store purchases go through Apple instead.

Frequently Asked Questions

Something not covered here? Write to support@picmal.app

How much can Picmal shrink an audio file?

A lot, depending on the source. Lowering the bitrate (e.g. 320 kbps → 128 kbps) roughly halves an MP3; forcing mono on a voice recording halves it again; and converting an uncompressed WAV to MP3 or AAC can cut size by 80–90%.

Does compressing audio lose quality?

Lowering the bitrate of a lossy format trades some quality for size. At 192–320 kbps it's transparent for music, and 64–96 kbps is plenty for speech. For archival, compress to FLAC instead, which is lossless.

How do I make a voice memo or podcast smaller?

Turn on force mono and pick a speech-friendly bitrate (64–96 kbps). Voice recordings don't need stereo or high bitrates, so the file comes out a fraction of the size with no audible difference.

Can I control bitrate and sample rate?

Yes. Pick VBR/ABR/CBR mode and a target bitrate, set the sample rate (8 kHz up to 96 kHz) and bit depth (16/24/32-bit), and force mono when you don't need stereo.

Can I batch compress a whole folder of audio?

Yes. Drop multiple files or an entire folder into Picmal and compress them all with the same settings in one pass.

Are my files uploaded anywhere?

No. All compression happens locally on your Mac. No uploads, no per-file limits. It's a one-time $39, not a subscription.
