The short answer. FlowVision is the one built around a cover-flow style waterfall rather than a grid. qView is the minimalist one designed for usability. LeafView and Tauview are the same idea built on different wrappers — Electron and Tauri respectively — so the interesting question between them is what the wrapper costs rather than what the viewer does. Pixpresso is the only one here that edits as well as shows. A viewer is the app you use fifty times a day for ten seconds, so the things that matter are startup, how it remembers where you were, and whether it opens the format your camera actually produced.
This guide covers 5 image viewers for macOS. Every fact below is drawn from the same verified records that back each app’s own page. The recommendations are our editorial judgment, not payment.

What actually decides this
- Navigation model. Cover-flow, grid, single image and filmstrip are four different ways of moving through a folder, and the one you want depends on whether you are picking or reading. A grid is for triage; a single image is for looking.
- What the wrapper costs. Two viewers built on the same idea and the same JavaScript library differ mainly in what sits between you and the file. That shows up as memory use and cold start on a folder of five hundred large images, not as features, and it is the axis that separates the Electron build from the Tauri one here.
- Format coverage, including what your camera writes. JPEG and PNG are table stakes. HEIC from an iPhone and a manufacturer RAW format are the ones that decide whether the viewer is actually useful, and a viewer that opens neither will hand the file to Preview instead of handling it.
- Viewer or viewer and editor. A viewer that also crops, resizes and converts is a convenience that comes at the cost of a heavier interface. If the conversion is a one-off, the system has tools for it; if it is a weekly job, having it in the same window is worth the bulk.
- What it remembers. Position in the folder, sort order, zoom level and which files you marked. On the second visit these are the difference between a viewer and a slideshow, and they are invisible until you have used the tool for a week.
Our picks
- FlowVision — Its record describes an RWaterfall-style viewer, which is the cover-flow navigation case. Choose it when you navigate a folder by moving through it rather than picking from a grid.
- qView — Its record describes an image viewer designed with minimalism and usability in mind, which is the lightweight case. Choose it when you want a minimal viewer that gets out of the way.
- LeafView — Its record describes a minimalist viewer based on Leaflet.js and Electron, which names both the base and the wrapper. Choose it when you want the Electron build of the Leaflet-based viewer.
- Tauview — Its record describes a minimalist viewer based on Leaflet.js and Tauri, which is the same idea on a smaller runtime. Choose it when you want the same viewer on the lighter wrapper.
- Pixpresso — Its record describes a viewer and editor for cropping, resizing, annotating and converting, which is the combined case. Choose it when you want conversion and annotation in the same window as the viewing.

How to choose
- Free of charge. Pixpresso — no payment is required.
- No licence fee, source available. FlowVision, LeafView, qView and Tauview — the source can be read and, under the terms of each licence, reused.
Open source: FlowVision, LeafView, qView and Tauview (4 of 5).
Common mistakes
- Judging a viewer on a folder of ten files. The interesting behaviour appears at five hundred, and so does the memory use.
- Assuming HEIC is covered because the app says it handles images. Support for the format your camera writes is a separate claim from support for images in general.
- Using a viewer as an image library. Once you need tags, ratings and search, you want a different category of tool and the viewer will keep disappointing you.
- Choosing the wrapper before choosing the navigation. The wrapper is a performance difference; the navigation model is the one you live with.
How this guide was put together
Each app’s facts come from its own record: the developer’s own pages and repository, the App Store listing where one exists, and the documentation, each with a source grade and an access date. Where a fact rests on the developer’s own statement rather than on something we verified independently, the sentence says so. Where our data has no value for something, the guide says “not published” instead of guessing.
A price appears here only where the record carries one from a stated source; the guide never estimates one, and it records the pricing model alongside so the two can be read together. Prices change and vary by region, so each app links to its own page for the current detail.
The facts and the recommendations are kept apart on purpose. Everything in the app entries, the comparison table and the answers above is composed from the records. The short answer, the criteria and the picks are our editorial judgment: they reflect what we would choose and why, and they are not paid for. Where we make a recommendation we name the condition it applies under, because we do not call anything “the best” without explaining the criteria.
Frequently Asked Questions
How do I choose between these image viewers?
There is no single answer — it depends on what you need. This guide covers 5 image viewers: FlowVision, LeafView, Pixpresso, qView and Tauview. They differ mainly in pricing model, licence and the trade-offs each one carries. Pick by the trade-off you care about rather than by rank.
Are these image viewers free?
Pricing across this group: open source (FlowVision, LeafView, qView and Tauview) and free (Pixpresso). We quote a price only where the record carries one from a stated source, and we never estimate one. Prices change and vary by region and by store, so always check the developer’s own page for the current figure.
Which of these image viewers are open source?
FlowVision (GPL-3.0), LeafView (MIT), qView (not published) and Tauview (MIT) are open source.
Do these image viewers support Apple Silicon?
Our data does not carry an explicit Apple Silicon statement for any app in this group, so we do not claim one. The absence of a statement is not the same as the absence of support.
How do I choose between them?
Start with how you pay: the guide groups these apps by pricing model, because the budget is the constraint most people actually have. Then check the trade-offs listed for each app: the limitations are the part that decides most people’s choice, because they describe what the app will not do for you.
