FlashView is a speed-focused photo viewer and culling tool for Windows, built for photographers who shoot large volumes. Point it at a folder of tens of thousands of RAW or JPEG files and start scrolling immediately — no catalog, no import, no waiting. Next/previous is near-instant, even on large RAW files (including Canon, Sony, Nikon), because FlashView reads the embedded preview instead of fully decoding every raw.

It's a viewer and culling tool, not an editor: browse, zoom, rate and flag your keepers, and write XMP sidecars that Lightroom, Capture One and other tools read back. No subscription - FlashView is a one-time purchase with a perpetual license.

Highlights: - Instant browsing of folders with tens of thousands of photos - No catalog or import step — just open a folder - Fast RAW viewing (incl. CR3) via embedded previews - Rate/flag for culling, XMP-sidecar compatible - Clean and distraction-free: no ads, no tracking, dark mode, keyboard-driven - One-time purchase, no subscription - Windows 10 / 11

Questions & Answers

As answered by people managing FlashView and nomacs.

What makes your product unique?

FlashView's answer

FlashView is built around one thing: speed. Open a folder of tens of thousands of RAW or JPEG photos and start scrolling instantly — no catalog, no import, no database. Next/previous stays near-instant even on large RAW files (including Canon, Sony, Nikon, etc), because it reads the embedded preview instead of fully decoding every raw. It's a focused viewer and culling tool, not a heavy all-in-one suite.

Why should a person choose your product over its competitors?

FlashView's answer

It's fast on large shoots and it's a one-time purchase with no subscription — unlike suites that moved to monthly plans. You get instant browsing, rating and flagging for culling, and XMP sidecars that Lightroom and Capture One read back — no ads, no tracking, no forced cloud account. If you already develop in Lightroom or Capture One and just need a fast way to view and cull, FlashView does that one job extremely well.

How would you describe the primary audience of your product?

FlashView's answer

Photographers on Windows who handle large numbers of images: wedding, sports and event shooters culling thousands of frames, plus enthusiast and advanced photographers who want a fast, modern image viewer without a subscription. It's for people who already edit in Lightroom or Capture One and want a quicker way to view and select.

What's the story behind your product?

FlashView's answer

FlashView began as a personal tool — a photographer frustrated that existing viewers crawled when pointed at folders of tens of thousands of RAWs. The goal was a viewer that feels instant on modern hardware: aggressive prefetching, embedded-preview decoding, and a clean keyboard-driven interface. It grew into a product for other photographers with the same problem.

Which are the primary technologies used for building your product?

FlashView's answer

.NET 8 and WPF on Windows, with Windows Imaging Component (WIC) for decoding, Direct3D-accelerated rendering, and multi-threaded prefetching and caching for low-latency browsing.

  • How can I export an image displaying in CMYK as RGB?
    How that cmyk profile is shown depends on the image viewing app too and if it [the app] can show that colour profile. Have you tried opening the image in a webbrowser, if it's updated and your monitor has the specs for it, try drag&drop the image to an open browser tab. As for img viewing app you can try nomacs.
