What people are
saying about Picmal
"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!"

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.
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.
Frequently Asked Questions

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 $29, not a subscription.
