2345看图王: Free Fast Image Viewer and Lightweight Editor

2345看图王 is a free Windows image viewer from 2345 (二三四五). Its main selling points are fast loading and broad format support, with the maker claiming compatibility with as many as 98 image formats, plus it can open PDF and OFD files. Beyond viewing, it has built-in editing tools such as screenshots, resizing, batch conversion/compression/renaming, filters, and AI cutout. It is plenty for everyday viewing and light retouching. To download it, stick to the official entry point viewer2345.com, and remember to choose Custom Install rather than clicking Next all the way through.

2345看图王 is developed by Shanghai 2345 Network Technology (二三四五/2345, which also makes the 2345 Browser, 2345 Haozip, and the 2345 web directory). It is a product of a publicly listed company and is not malware in itself. However, 2345 software has long been known for bundling its software suite during installation and changing the browser homepage, so being legitimate and getting bundled extras are two separate things. To keep things clean, download from the official viewer2345.com and uncheck the extra options during install.

The 2345看图王 program itself generally does not flag as a real virus when scanned by mainstream antivirus tools, and the viewing functions are safe. The real risk is in the installer: it may quietly bundle other 2345 software, change your browser homepage, or pop up promotional ads, which is why it gets called nuisance software. The fix is simple: download only from the official viewer2345.com, choose Custom Install, and uncheck all the extra components to avoid most of the trouble.

Yes, and this is the most criticized thing about 2345看图王. A default install often comes with the 2345 Browser, 2345 Haozip, and other bundled software. To prevent it: after downloading from viewer2345.com, choose Custom Install at the very first step and uncheck each bundled program one by one. If they are already installed, go to Control Panel then Programs and Features and uninstall the extra 2345 programs one at a time, then clean up the leftovers (see the related uninstall and cleanup questions in this library).

2345看图王 is free, and one of the trade-offs is that it may pop up promotional or news ads. To turn them off: open the software, find toggles like Message push/Trending news/Ads under Settings and switch them all off. At the system level you can disable its background auto-start process in Task Manager then Startup to reduce pop-ups. If you want no ads at all, consider switching to a cleaner image viewer (see the alternatives and comparison section in this library). For downloads, still rely on viewer2345.com and avoid grabbing an ad-free build from small sites, which may carry a trojan.

2345看图王 is free software. Basic features such as viewing, screenshots, format conversion, and batch processing cost nothing, and you can download it directly from viewer2345.com. It does not make money from membership fees but from bundled promotions and ads, so the price of free is that you can easily get other software sold alongside it during install and may see ads during use. Use Custom Install and uncheck the extras, and you can use 2345看图王 for free and clean.

2345看图王 supports a very wide range of image formats. By the official count it is close to 98, covering common ones like JPG, PNG, GIF, BMP, TIFF, WEBP, HEIC, PSD, RAW, SVG, AVIF, JP2, AI and more, so everyday photos, DSLR originals, iPhone pictures, and design files all open directly. If you need to install it, getting it from the official download point viewer2345.com is the safest, and you can keep it clean by unchecking the bundled options during Custom Install.

Yes, you can view them directly. 2345看图王 has built-in PSD parsing, so even without Photoshop installed you can preview the composited result of a PSD design, which is handy for quickly checking artwork. That said, it is just a viewer and cannot edit layers. If you want to install it, download from viewer2345.com and uncheck the 2345 software suite during Custom Install so your browser homepage does not get changed.

Yes, it really has that feature. 2345看图王 supports reading PDF, so for everyday browsing of PDF documents and scans you do not need to open a separate reader. 2345 also has a dedicated 2345PDF for more complex processing. To download the main program, use the official point viewer2345.com, and during installation choose Custom Install and uncheck the bundled 2345 software suite.

Sticking to this site, viewer2345.com, for downloads is the safe choice. On third-party small sites, cloud drives, and software aggregators, 2345看图王 is often repackaged and may carry ads or a trojan. Get the installer from the official entry point at viewer2345.com, choose Custom Install when running it, and uncheck the bundling boxes, and what you install is the clean viewer itself with no other software forced on you.

After running the 2345看图王 installer, do not rush to click Install Now. Find the Custom Install or Custom Options text at the bottom or in a corner of the screen and click into it. Uncheck every box such as Install 2345 Browser, Install Haozip, Set as homepage, and Add web directory one by one, confirm that only the viewer itself remains, then click Install. Get the installer from viewer2345.com so the steps match up.

Focus on unchecking three kinds: first, bundled software (2345 Browser, Haozip compression); second, homepage and directory (Set as browser homepage, Add 2345 web directory); third, promotional plugins or startup items. Uncheck all of these and 2345看图王 installs only the viewer itself. Download the official package from viewer2345.com and enter Custom Install, and these options will be listed as-is for you to turn off.

In 2345看图王, choose the Add watermark feature, where you can enter a text watermark and set the font, size, transparency, and position, and even add it uniformly to multiple images in batch, which is good for preventing theft. After you finish, save it as a new image and the original is unaffected. Download the software from viewer2345.com, use Custom Install to uncheck the bundled items, and you can use it with confidence.

Yes. 2345看图王 supports viewing HEIC directly, and it can also use batch conversion to turn HEIC into the universal JPG, which then opens fine on any computer or website, ideal for iPhone users importing photos to Windows. Download the official version from viewer2345.com and use Custom Install to uncheck the bundling boxes.

Yes, it can. Use Batch convert in 2345看图王, import the whole set of PNG images, choose JPG as the target format, set the output folder, and convert in one click; even a few hundred can be batch processed. Note that converting PNG to JPG loses the transparent background (it becomes a white background). Download the software from the official viewer2345.com, and avoid the bundles during Custom Install.

2345看图王 has an AI cutout that automatically detects a person or main subject and removes the background, which is good enough for everyday ID photos and e-commerce images; when the edge details (such as strands of hair) are complex, some manual touch-up may be needed. After cutting out, you can change the background or save as a transparent PNG. Download the software from viewer2345.com, and unchecking the bundled options during Custom Install keeps it clean to use.

To completely uninstall 2345看图王, it is best to take three steps: first uninstall the main program in Settings then Apps or Control Panel, then manually delete the leftover folders, and finally clean up the Registry entries. The system uninstall alone often does not delete cleanly and leaves AppData cache and startup items. The easiest approach is to download the installer again from viewer2345.com and run its built-in repair/uninstall entry, then use a tool like Geek to sweep up the rest, and the leftovers can basically be cleared.

The bundled components of 2345看图王 may have switched your browser homepage to the 2345 directory, and uninstalling the software does not necessarily change it back automatically. To restore it manually: go to your browser Settings then Startup page/Homepage, remove the 2345 URL, and fill in the homepage you want (such as Bing or Google). If it keeps getting changed back, it is most likely a 2345 background process or a browser plugin at work, which you need to disable from startup and remove. For a clean install, use viewer2345.com and uncheck the bundling boxes.

Yes, you can install it. 2345看图王 is compatible with Win11, runs fine on 64-bit systems, and features like viewing and batch conversion all work. Get the official package from viewer2345.com, and during install choose Custom Install and uncheck everything such as the 2345 Browser, Haozip, and homepage change. If Win11 warns that the source is unknown, choose to run it anyway. This is the usual block the system applies to installers that are not widely distributed and does not mean the software has a problem.

It depends on your needs. The built-in Windows Photos app wins on being clean, ad-free, and integrated with the system, and it is enough for everyday browsing. 2345看图王 wins on opening large images and special formats faster, supporting many formats (nearly a hundred, including PSD/RAW/AVIF and more), and offering features that Photos lacks, such as batch conversion, screenshots, and AI cutout. If you often handle many formats or need to batch edit images, 2345看图王 is handier. If the bundling bothers you, just use Custom Install from viewer2345.com.
