Zipic review for fast local image compression on Mac

What Zipic is and who it is for

Zipic is a native image compression tool for Mac, with a Windows version now in beta on the Microsoft Store. It compresses, converts and resizes images locally on your device to reduce file sizes, so nothing is uploaded to a server. The maker is 5KM Tech, and the app is sold as a one-off license rather than a subscription.

It is aimed at people who handle a steady stream of images: web designers and developers trimming files before upload, bloggers who paste screenshots into posts, app developers who need ICNS icons, and anyone whose screenshots folder keeps growing. If you only shrink a handful of images a month, the free tier or a free utility will likely be enough. Zipic makes more sense when compression is part of your daily workflow and you want it to happen in the background.

Key features of the Zipic tool

Compression, resize and conversion

The vendor lists six compression levels (a higher number means smaller files), quick resizing, and conversion between WebP, HEIC, JPEG and other types. You can replace the original file, save a copy with a suffix, or send output to a chosen location. Batch processing is included on the free plan, so you can drag and drop a whole folder into the main window and let it work through the images.

Zipic's docs say it reaches high compression ratios "up to 90%+" while keeping images visually lossless. That is the vendor's own claim, and real results depend on the source files, so treat it as a best case rather than a promise.

Supported image formats

Zipic supports 12 image formats. The free plan covers JPEG, PNG, WebP, HEIC and GIF. The paid license adds AVIF, JPEG XL (JXL), TIFF, ICNS, PDF, SVG and APNG. The FAQ also mentions native WebP encoding (including animated WebP) and progressive JPEG on by default. This broad list is the main thing that separates it from older Mac compression apps.

Workflow automation

This is where the upgrade earns its price. Folder monitoring compresses new images that land in a watched folder, with custom rules. Clipboard auto-compress shrinks any image you copy, which pairs well with a screenshot app. Notch Drop lets you drag images onto the MacBook screen notch without opening the app window. There is also a Finder right-click menu, a menu bar item, a Raycast extension, Apple Shortcuts support and a URL scheme for scripting.

Privacy and performance

All processing happens on your device and images are never uploaded, according to the vendor, and it works offline. That matters if you handle client work, unreleased product shots or anything sensitive. Zipic says it uses open source libraries, and an independent review on AppAddict notes the engine is built on mozjpeg, pngquant and similar tools that most of this category runs on, so raw results may not differ much from rivals that use the same libraries. The difference is in the design and how little you have to think about it.

Interface and install

Zipic is a native app, so it follows the macOS look, including dark and light mode, and the vendor says it is built for both Apple Silicon and Intel Macs. Once installed, you can use it from the main window, the menu bar or Finder. The AppAddict reviewer described the idea as drag, drop, done, and praised how easily it fits into existing habits, and the user quotes shown on the Zipic site mostly praise the interface and design.

Pricing and Pro plans

Zipic uses a pay once model with lifetime updates. Prices below were shown on zipic.app when checked, as a discount against a higher list price.

The pricing page also has a one-device option on the Personal plan. The key is emailed straight after purchase. There is no subscription option, which some buyers will see as a plus.

Limits and system requirements

• Images only. Zipic does not handle video. If you also want to shrink screen recordings, you will need another tool.
• System requirements. The Mac app needs macOS 13 (Ventura) or later, so older Macs are out. The Windows version is still labelled beta.
• Free tier is capped. After the trial you get 25 images a day and only the basic formats, and the automation is paid only.
• Strong cheaper competition. The AppAddict reviewer liked Zipic but stayed with Clop, which offers similar folder watching and clipboard automation at a lower one-off price and also handles video and PDFs. Zipic's remaining edge in that scenario was its wider image support.
• Support is email based. The vendor offers documentation and an email address, and says it typically replies within 24 hours.

Alternatives

• Clop: Mac compression with clipboard and folder automation that also covers video and PDFs.
• ImageOptim: free, open source Mac app focused on lossless compression, with no automation or conversion.
• Squoosh: free browser-based compressor for one image at a time, handy if you do not want anything installed.

Verdict

Zipic is a well-designed, local image compression tool for Mac with a fair one-off price and wider format support than most rivals. I would pick it if you work with AVIF, JPEG XL or ICNS and want compression to run automatically from a watched folder or the clipboard. If you only compress the odd photo, or you also need video, a free tool or Clop is the better fit. Try the 7-day Pro trial first, as it shows quickly whether the automation makes your day easier.
