Picmal: The Mac Media Converter We Didn't Know We Needed
Most of us convert media the lazy way. You search for “HEIC to JPEG”, open whichever site loads first, drop the file in, and wait for the download button to appear. That workflow works—right up until there are forty images instead of one, or you’re dealing with documents you don’t want sitting on someone else’s server.
macOS doesn’t completely solve this problem. Preview can export images if you know where to look, and QuickTime handles a handful of video formats. For everything else, you end up jumping between browser-based converters, small utilities, or even Terminal commands.
Picmal, from indie developer Alberto Gallego, takes that entire workflow offline and brings it into a single Mac app.
What is Picmal?
Picmal is a macOS app that converts and compresses images, video, and audio on your own machine. It means you don’t have to worry about creating an account, uploading your files anywhere, or paying a subscription fee. You drop in files or a whole folder, choose an output format or a compression preset, and it does the job.
The idea behind Picmal is very simple. As developer Alberto explains:
“Picmal started because I was tired of opening a browser every time I needed to convert a few files. I figured there had to be a better way, so I built one.”
That philosophy has remained consistent as the app has grown. Alberto says he has tried to stay true to three principles: your files should stay on your computer, the app should feel at home on your Mac, and you should only have to pay once.
What we like is that Picmal isn’t trying to be an editor. It converts, compresses, and resizes in bulk, and that’s the end of the feature list. When we first came across Picmal, we wanted to test its privacy-focused approach to all sorts of conversions, but we’ve grown to like it for more than that.
Features Highlight
- Everything stays offline. Every conversion happens locally, so your files never leave your Mac.
- Batch processing built for real workloads. Convert, compress, or resize thousands of files with presets and automation.
- Supports images, videos, audio, and PDFs. One app replaces several small conversion utilities, more than an image converter.
- Deep macOS integration. Finder, Shortcuts, Raycast, watch folders, and command-line support make repetitive jobs much faster.
Three Sections on Picmal
Rather than overwhelming users with dozens of individual tools, Picmal combines its capabilities into a straightforward workflow. During our testing, three sections consistently stood out.
Media
The Media section contains the Convert and Compress tools, and images and videos share the same queue. This means a folder of HEIC shots, a PSD, and an MP4 can go through in a single pass. Resizing offers six modes, and maximum file size criteria earns its place because “get this under 2MB” is an instruction real people are actually given. Video Options adds a Resolution setting from 2160p down to 360p, and Picmal only ever scales down while holding the aspect ratio.
Remove Background is the one we keep going back to, and it beats the built-in macOS utility often enough that we stopped checking the result. Vectorize traces a PNG or JPG into a real SVG with actual paths, and it handles a whole batch in one pass. Picmal will also turn a multi-page PDF into one image per page, which is exactly the five-minute job that usually sends people back to a stranger’s server.
Audio
The audio side covers around 30 formats, though the compression controls matter more than the count. You can target a bitrate, choose VBR, ABR, or CBR, change the sample rate, or force a stereo file down to mono.
The audiobook handling is where it stopped feeling like a converter, since M4B files convert to and from M4A and MP3 with chapters and cover art intact, while Split by Chapter breaks a long book into one file per chapter, and Merge Audio turns loose tracks back into a chaptered M4B.
The PDF section is the newest part of the app and the one changing fastest, which cuts both ways. Organize Pages reorders and deletes pages visually, Split PDF cuts a document by page range, and Combine PDFs merges several documents in whatever order you drag them into.
Images to PDF works the other way around, building a multi-page document from a batch of images, with a choice of page size and quality, an optional password, and a filename of your own. It’s small, but it replaces the one browser upload we always felt worst about.
Our Hands-on Take
Picmal enters a category that is already busy and almost saturated. Permute has been converting files on the Mac for years, ffmpeg does all of this for free if you’re willing to live in a terminal, and the web is full of converters that ask for nothing but your files. Picmal sits in the space between those options.
The app keeps everything local, it works quickly, and it doesn’t ask you to make a single decision before your first conversion.
UI & Quality
The entire interface fits into a single window, with a toggle at the top and a drop area below it. Once you’re ready to convert files, the workflow is refreshingly simple. Drag your files—or an entire folder—into the window, choose an output format or preset, and start the conversion. Progress is displayed for each file individually, and you can save the results beside the originals or in a destination folder of your choice.
For most users, there isn’t much to learn. The interface stays out of your way, while more advanced controls remain available whenever you need them.
Finer Control
Picmal lets you save your frequently used settings as presets. You choose an output format, a compression level, and a resizing rule (if needed), and then you can drop files onto the preset instead of rebuilding those settings each time.
The automation goes further with watch folders: anything you drop into a designated folder is converted according to the rules you’ve already set, and the app never has to come to the front. The app even ships with a command-line tool that behaves exactly like the interface, and that is a genuinely nice surprise too.
Performance & Privacy
Picmal runs every conversion on your own Mac, and that brings you two benefits. Your files never leave the machine, which matters the moment you’re handling anything you’ve promised to keep confidential. And instead of waiting on an upload, a queue, and then a download, Picmal runs the job on your own cores in parallel.
On Apple Silicon, that difference is easy to notice. Picmal can also strip metadata, and we appreciate that more than we expected to. The app will remove GPS coordinates and camera information from the file as it converts, and no online converter has ever offered us that.
Room for Improvement
Our biggest issue with Picmal is the absence of a free trial. You can install the app and click around, but you cannot convert a single file without buying it first, and a refund window is not the same reassurance as running your own files through the app for a week.
For an app whose main selling point is that it handles your files safely, asking for trust before it demonstrates any is an odd choice. Accessibility support is also fairly limited, and Picmal is currently available only in English.
Picmal Pricing
Picmal is available as a one-time purchase, which already makes it stand out in a category where many utilities have moved to subscription pricing.
A lifetime license starts at $39, including future updates. That’s an approachable price for a Mac utility, especially if media conversion is something you do regularly rather than occasionally.
How Picmal Compares to the Alternatives
Most Mac users already have several ways to convert files. The question isn’t whether Picmal can do the job—it’s whether it offers a better workflow than the tools you already have.
| Tool | Best for | Limitations |
|---|---|---|
| Preview | Occasional image or PDF conversion | Limited batch processing, almost no automation, no audio or video support |
| Online converters | One-off jobs | Upload limits, slower workflows, privacy concerns, inconsistent quality |
| ffmpeg | Advanced users and scripting | Extremely powerful, but intimidating for most people |
| Permute | Beautiful interface and media conversion | Strong competitor, but less focused on workflow automation |
| Picmal | Frequent conversions across images, audio, video, and PDFs | No free trial, fewer editing capabilities |
If you only convert a handful of files every month, Preview or an online converter may already be enough. But if file conversion has quietly become part of your weekly workflow—whether you’re creating content, managing media, or handling client files—Picmal starts making a compelling case for itself.
Final Verdict
Picmal handles a small task that most Mac users run into repeatedly. If you convert or compress media regularly, the app removes browser tabs and upload waits from the equation while ensuring that this year’s files stay on the device. The best part? It does it all without a subscription.
The format’s coverage is wide enough to accommodate whatever you have, and because the queue does the work, the fortieth file costs you no more effort than the first. Moreover, Picmal is not an editor, and it doesn’t pretend to be one.
Though there’s no free trial, the app costs under forty dollars once, and there is a refund window sitting behind that, so the trust the developer is asking for is small. While we understand Picmal isn’t for everyone, many people we know will definitely benefit from it.
