Do you need an MD editor that can generate content with AI, convert markdown into mind maps, or convert brain maps into markdown?
Just like the video demonstration。

How do you quickly review a folder with 10+ image formats? Here’s the workflow we built
Disclosure: I’m part of the team building OpenFiles.
If a folder contains only JPG and PNG files, the system image viewer is usually enough.
The frustrating part starts when one project folder contains JPG screenshots, PNG exports, iPhone HEIC photos, WebP and AVIF files downloaded from the web, TIFF scans, a JXL image, and several camera RAW files. You can end up converting files just to inspect them, or opening several apps before you have even decided which images you want to keep.
This mixed-format folder is one of the workflows we designed OpenFiles around.
OpenFiles is a desktop file manager for Windows and macOS with a built-in image viewer. It currently recognizes 27 image formats, including common formats and less convenient ones such as HEIC/HEIF, AVIF, WebP, TIFF, JXL, PSD, SVG, DNG, and multiple camera RAW formats.
The number of formats is not really the interesting part, though. The useful part is being able to stay in one folder while you:
- browse the folder as a gallery and open images without choosing a different app for each format;
- switch between mixed-format files for a first review;
- zoom, pan, rotate, or fit an image to the window;
- place two images side by side in a resizable split view;
- run OCR when an image contains text; and
- convert supported camera RAW files to JPG or PNG when you need a more portable copy.
There are a couple of boundaries worth stating clearly. “27 image formats” describes the image viewing coverage; it does not mean that every one of those formats can be converted to every other format. The current batch converter is narrower: it supports camera RAW to JPG/PNG and LIVP to JPG/MOV. OpenFiles is also not intended to replace Lightroom, Photoshop, or another full photo editor. It is mainly for opening, reviewing, comparing, and organizing files before deeper editing is necessary.
OpenFiles is proprietary and free to use. If your folders contain only ordinary JPG and PNG images, it may not add much over the viewer you already have. I think the difference becomes more useful when files arrive from several phones, cameras, design tools, websites, or clients and all land in the same folder.
If you regularly deal with mixed-format image folders, what causes the most friction for you: missing format support, slow thumbnails, switching between files, comparing near-duplicates, or converting the final selection?

Update: JPEG XL support is now available in OpenFiles Desktop 3.2026.802.
Update: JPEG XL support is now available in OpenFiles Desktop 3.2026.802.
This first release includes direct .jxl opening and preview, in-app thumbnails while browsing folders, and animated JXL playback.
This is a first milestone, not a claim of complete JPEG XL support. It does not yet include progressive or partial-decode inspection, bandwidth emulation, layer-by-layer viewing, or a fully verified HDR, wide-gamut, ICC and XMP workflow.
I’m still looking for real files that expose orientation, color, metadata or performance problems. If you test the release, please include your platform, the sample file if shareable, and what you expected versus what OpenFiles displayed.

I’m building a lightweight DWG/DXF viewer for quick checks — what should it never get wrong?
Sometimes I receive a DWG or DXF file that I don’t need to edit. I just want to open it, inspect the drawing, and decide whether I need to fire up a full CAD package.
I’m the developer of OpenFiles Desktop, and I’ve been working on a local viewer for that workflow. It can open DWG and DXF files directly, but it’s meant for quick inspection—not as a replacement for AutoCAD or a full CAD editor.
The basic viewer works. What I’m more interested in are the things lightweight viewers usually get wrong: missing fonts, broken hatches or line types, layouts, external references, units, large drawings, or compatibility with different DWG versions.
For a quick review, do you need layer controls and measurements, or is accurate rendering enough?
If there’s anything else you’d want from a lightweight CAD viewer, feel free to mention it. I’m still deciding what to work on next, so even small workflow frustrations would be useful to hear about.
The screenshot shows a sample drawing opened in the current version. If you have a file that other viewers usually render incorrectly—and you’re allowed to share it—I’d be happy to test it.

If a desktop file viewer added JPEG XL support, what would you want from it?
Hi, I’m working on OpenFiles Desktop. It doesn’t support JPEG XL yet, but I’m looking into adding it.
Before I start, I’d like to understand what people who actually use JXL expect from a desktop viewer.
Is being able to open a .jxl file enough, or would you also want things like:
- thumbnails and folder browsing
- EXIF, XMP and ICC profile support
- HDR and animation
- lossless JPEG transcoding
- batch conversion to and from JPEG, PNG or AVIF
- exporting without losing metadata
I’m also interested in the less obvious problems. Are there particular JXL files that other viewers display incorrectly? Things like wrong colors, orientation issues, missing metadata, slow decoding, or unusually large images?
What platform are you using, and what does your current JPEG XL workflow look like?
If you have a sample file that tends to break viewers, feel free to share it. I’d be happy to test against real-world files rather than only simple samples.

Welcome to r/OpenFilesDesktop — one app for 350+ file formats
Hey everyone — welcome to r/OpenFilesDesktop
I’m the developer of OpenFiles, and I created this community so users can talk directly with me and with each other.
OpenFiles began with a very small frustration: I had backed up an iPhone Live Photo as a .livp file, but the service holding it could not preview it. Solving that one unusual format led to a much bigger question:
Why should opening an unfamiliar file mean hunting down and installing another single-purpose app?
Today, OpenFiles is a privacy-first desktop app that opens 350+ file formats across images, documents, code, video, audio, archives, mind maps, data files, and more. The goal is to make file work less fragmented: browse, preview, make lightweight edits, convert or export, and bring AI assistance into the same desktop workflow. Core file processing happens locally, so you do not have to upload a private file to a random online converter just to inspect it.
The longer-term vision goes beyond being a universal file viewer. I want OpenFiles to become a practical, local-first home for AI-assisted file work — a place where an assistant can help you understand documents and code, analyze structured data, and turn results into useful files that stay part of your normal desktop workflow. That vision is still being built, and this community should help shape it.
What belongs here
- Ask how to open, preview, edit, or convert a file format.
- Share a useful or unusual OpenFiles workflow.
- Report bugs and compatibility problems.
- Request new formats or features — real use cases are especially helpful.
- Share honest feedback, including what feels confusing or unfinished.
- Follow development updates and help test new releases.
When reporting a problem, please include your operating system, OpenFiles version, file extension, and the steps that caused it. Screenshots and sanitized sample files are helpful, but please never post confidential or personal files publicly.
OpenFiles is still growing, and specific feedback from real workflows has a direct impact on what gets built next. If the app saved you from installing one more tool, I would love to hear about it. If it failed on the exact file you needed, I want to hear that too.
To get things started:
What is the strangest, most frustrating, or most important file format you regularly work with?
Thanks for being here.
