What's new in v1.8.1

The ImageOptim alternative that also converts formats

ImageOptim is free, local, and good at what it does. It just can't convert a HEIC to a JPG, touch a video, or compress a PDF. Picmal does all of that on your Mac for $15.99 once.

TL;DR Picmal vs ImageOptim

ImageOptim is free, open source, runs entirely on your Mac, and squeezes PNG and JPEG about as hard as anything out there. Its limits are that it only compresses, only images, and development has been quiet for years. Picmal ($15.99, pay once) converts formats too, covers video, audio, and PDFs, and is actively maintained.

Pick Picmal if
You need to convert formats, not just compress. Or you've got video, audio, and PDFs to deal with and would rather not collect four apps.
Pick ImageOptim if
You compress PNGs and JPEGs for the web, you want the smallest possible file, and free and open source matters to you. It's a good tool, keep it.

Which one is right for you?

Here's where each one makes more sense.

Choose Picmal

Compression alone isn't the job

  • You need to convert formats, HEIC to JPG being the usual one
  • You want newer formats like AVIF and JXL, not just PNG and JPEG
  • Video, audio, or PDFs are part of the same pile of work
  • You'd rather use something that's still being maintained

Stay with ImageOptim

Free, open source, and it does the job

  • You only ever compress PNG and JPEG for the web
  • You want the last few percent of file size and nothing else
  • Free and open source is the point, not a compromise

"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)."

A note from Picmal's founder

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

Frequently asked questions

Can't find what you're looking for? Email support@picmal.app

Is Picmal a good ImageOptim alternative?

It depends what you're missing. ImageOptim is free, local, and very good at squeezing PNG and JPEG without visible loss. If that's all you need, keep it. Picmal is worth $15.99 if you also need to convert formats, handle video, audio, or PDFs, or want the app to still be getting updates.

Can ImageOptim convert between formats?

No. ImageOptim compresses an image and leaves it in the same format. It won't turn a HEIC into a JPG or a PNG into a WebP. That's the single most common reason people go looking for an alternative, and it's what Picmal does.

Is ImageOptim still being updated?

Development has been very quiet for a long time. It still works well on the formats it supports, but it hasn't kept pace with newer ones like AVIF and JXL, or with changes in macOS. Picmal ships updates regularly, listed at picmal.app/changelog.

Does Picmal compress as well as ImageOptim?

For everyday web and storage use, the difference isn't something you'll see. ImageOptim runs several open source optimisers in sequence and can shave out the last few percent on PNG, which matters if you're chasing absolute minimum size. Picmal trades that last few percent for covering video, audio, PDFs, and format conversion in one app.

Do both keep files on my Mac?

Yes. This is one thing they genuinely share. Neither uploads your images anywhere, both work with no internet connection. If you're comparing either of them to a web converter, that's the real difference.

Is ImageOptim free?

Yes, and open source. That's a real advantage and worth saying plainly. Picmal costs $15.99 once, so it only makes sense if the extra formats, media types, and integrations are worth that to you.

What if Picmal doesn't work for me?

Full refund within 14 days, no questions asked. Email support@picmal.app.
