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."

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.
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.
