What Picmal actually does

Convert, compress, and resize images, video, audio, and PDFs. All on your Mac, nothing touches a server.

Convert, compress & PDF

Anything in, anything out

Any format, in or out

Images, video, audio, RAW, PDF — over 100 formats. PSD to PNG, MOV to MP4, FLAC to ALAC. Pick the output and go.

See it before you commit

Slide between the original and the compressed version, then dial in the quality.

Before/after slider comparing the original 1.6 MB photo with the 145 KB compressed version

RAW and PDF, too

Camera RAW in, JPEG out. Rasterize a PDF to PNG at the DPI you pick.

Smaller files, same quality

Fit an email limit or a slow upload without the quality drop you'd actually notice. Convert and compress in one pass.

Combine PDFs

Merge a stack of PDFs into one. Drag to reorder pages, pick the page size, save it out.

Images to PDF

Turn a batch of photos into a multi-page PDF. A4, Letter, or custom — with an optional password.

Batch & automate

Built for hundreds of files

Drop a folder, walk away

Thousands of files at once, whole folders, mixed formats. Picmal sorts out each file type and works through them all.

Run it overnight

Schedule big jobs for later. They survive quitting the app.

Watched folders

Drop a file in, it converts itself. Set it once, forget it.

Optimize from the clipboard

Copy a screenshot, paste it back smaller. Picmal compresses what's on your clipboard automatically.

Presets & controls

Simple by default, deep when you need it

Presets for the usual stuff. Full control for the rest.

One-click presets for web, social media, and archiving. Save your own when none of them quite fit.

Picmal presets and settings

Watermarks

Stamp every file in a batch, scaled to fit any size.

Your metadata stays

Keep camera info, dates, and GPS — or strip what you don't want shared.

Why Picmal

Private, offline, and yours

Designed for Mac

Built in Swift for Apple Silicon and designed around macOS. It plugs into Finder, Quick Actions, and Shortcuts, and feels like it came with your system — not an Electron wrapper.

Works offline

No internet required, ever. Convert on a plane, at a café with terrible Wi-Fi, or with the network off completely. Nothing queues and nothing waits on a server.

Privacy first

Your files never leave your Mac. Nothing is uploaded, there's no account, and nobody tracks what you convert. What's on your machine stays on your machine.

"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). "

Is Picmal a good Kompressor alternative?

If you need more than image compression, yes. Picmal converts and compresses images, video, audio, and PDFs in one app, with Shortcuts, folder monitoring, and Finder right-click. Kompressor is a great free option if images are all you need.

Does Picmal have real-time preview like Kompressor?

No — Picmal batches files without the per-file preview. If seeing the before/after for each image before committing matters to you, Kompressor's live preview is genuinely useful.

Why pay for Picmal when Kompressor is free?

Kompressor is image-only and free. Picmal is $15.99 and covers video, audio, and PDFs alongside images — plus format conversion, metadata removal, Shortcuts, and folder monitoring. If image compression is all you need, Kompressor is a perfectly good choice.

Can Kompressor convert video files?

No. Kompressor is image-only. For video — or audio, or format conversion — Picmal covers those.

What if Picmal doesn't work for me?

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