Here's where each one makes more sense.
You're compressing constantly, or your files are big
Occasional web images, and free is hard to beat
One app for images, video, audio, and PDFs. Convert, compress, and edit, all on your Mac. These are the essentials, and there's plenty more in the docs.
Over 100 formats across images, video, audio, RAW, and PDF. HEIC to JPG, MOV to MP4, FLAC to ALAC. Drop it in, pick the output, done.
Get under an email limit or a slow upload, without the quality drop you'd actually notice. No browser, no waiting.
Break a PDF apart, or drag pages around to reorder, rotate, and delete. Your documents never leave your Mac.
Stitch a pile of clips into one video. Drag to reorder, pick the format, export in a single pass.
Join tracks into one file, or split a long recording by its chapters. Podcasts and audiobooks, sorted.
Turn a folder of photos into a multi-page PDF. A4, Letter, or custom, with a password if you want one.
Merge a stack of PDFs into one file. Put the pages in the right order, set the size, and save it out.
Finder, Shortcuts, and Raycast. A conversion is never more than a right-click away.
Script it, drop it in a cron job, or hand it to a coding agent. The same engine as the app, right from your terminal.

Hello there 👋
I'm Alberto, the developer behind Picmal.
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.
Over time, that simple image converter has grown into something much bigger, mostly thanks to the people who use it.
Along the way, I've tried to stay true to a few simple ideas: your files should stay on your computer, the app should feel at home on your Mac, and you should only have to pay once.
One of my favorite parts of building Picmal is talking to customers. Many of the features in the app today started as conversations with people who needed something that didn't exist yet.
So if there's a feature you've always wished for, or something you haven't found in other tools, I'd love to hear from you. If it fits Picmal, I'll do my best to build it.
Best,
Alberto

If you compress images regularly, yes. Picmal does the same job on your Mac with no per-file size cap, no 20 image batch limit, and nothing uploaded. TinyPNG is excellent and free for occasional use, so if you compress a few images a month there's no reason to switch.
20 images at a time, 5MB each. Format conversion is limited to 3 free images, while compression itself is unlimited in batches of 20. Files are uploaded to their servers and deleted within 48 hours. Picmal has no caps because nothing leaves your Mac.
For normal web use the results are close enough that you won't see a difference at the same file size. TinyPNG has spent years tuning its lossy PNG quantisation and is genuinely very good at that one job. Picmal compresses JPG, PNG, WebP, HEIC, AVIF and more, plus video, audio, and PDFs.
In Picmal, yes, there's no size limit. That's usually the reason people look for a TinyPNG alternative, since camera photos and screenshots on a retina display go past 5MB easily.
Yes. It's a web service, so images are uploaded, compressed on their servers, and downloaded back. They state files are deleted within 48 hours. Picmal never sends an image anywhere and works with no internet connection at all.
Full refund within 14 days, no questions asked. Email support@picmal.app.
