Icaros vs SVG Explorer Extension for designers: Explorer thumbnails, video and SVG previews, systems, pricing and setup, compared from each tool's own sources. | Option | What it previews in Explorer | Systems | Price | Settings you can change | |---|---|---|---|---| | Icaros | Thumbnails for essentially any video media format FFmpeg supports [^1], plus properties for many popular media filetypes [^1] | Windows Vista, 7, 8/8.1, 10 and 11 [^1] | not published | Thumbnailing and properties on or off [^1]; cache size limit in MB with 0 meaning unlimited [^1] and a changeable cache location | | SVG Explorer Extension | SVG thumbnails in Windows Explorer so a user can keep an overview of SVG files [^2] | not published | not published | Installer must match the system's architecture; a 32-bit installer runs on a 64-bit system but the extension will not function [^2] | | SageThumbs 2K | Thumbnails for 363 file types Windows can't render natively, including camera RAW, Photoshop PSD, HEIC/AVIF and video [^3] | Windows 11, x64 and ARM64 [^3] | Free for personal, noncommercial use [^3]; commercial use US$2.99 a month or US$49 once per installation [^3] | Previews in Explorer [^3], right-click convert and combine to PDF [^3], Space-bar preview [^3] | ## The short answer Icaros adds Windows Explorer thumbnail previews for video file formats and media properties, while SVG Explorer Extension adds Explorer thumbnails for SVG files. SageThumbs 2K works inside Windows File Explorer, so the folders a designer already uses show pictures of files instead of blank icons [^3]. It also pulls previews out of design and CAD files such as Photoshop, Affinity, AutoCAD DWG and CorelDRAW [^3]. Icaros's page lists video thumbnails for essentially any format FFmpeg supports [^1] and Explorer properties for many popular media filetypes, on Windows Vista through 11 [^1]. SVG Explorer Extension's page limits itself to SVG thumbnails so a user can keep an overview of their SVG files [^2]. ## What Icaros, SVG Explorer Extension is built for Icaros's own page describes it as a collection of lightweight, high-quality add-ons that extend what Windows Explorer can show [^1]. It can provide Windows Explorer thumbnails for essentially any video media format supported by FFmpeg [^1], and it also provides Explorer property details for many popular media filetypes. The core add-ons have no dependencies [^1], though the settings program requires .NET Framework 4 [^1]. It works on Windows Vista, 7, 8/8.1, 10 and 11 [^1], with version 3.0.3 and earlier working partially on Windows XP with thumbnails only [^1]. Thumbnailing and properties can each be turned on or off [^1], the cache can be given a maximum size in megabytes with 0 meaning unlimited [^1], kept from growing when the hard drive runs low on space [^1], and moved to a location of choice [^1]. SVG Explorer Extension's page says it is an extension module for Windows Explorer that renders SVG thumbnails so a user can have an overview of their SVG files [^2]. Its installer must match the system's architecture, because a 32-bit installer will run on a 64-bit system but the extension will not function [^2]. Its page says little else, so check its own page for the systems it supports and for anything beyond thumbnails. ## What SageThumbs 2K is built for SageThumbs 2K is made by the team that publishes this site. It adds File Explorer thumbnails for 363 file types Windows can't render natively, including camera RAW, Photoshop PSD, HEIC/AVIF and video [^3]. For design and CAD files such as Photoshop, Affinity, AutoCAD DWG and CorelDRAW, it pulls an embedded preview straight out of the file, so the file does not have to be drawn from scratch [^3]. Thumbnails also work in OneDrive and Synology Drive folders, and it never downloads online-only files just to draw a thumbnail [^3]. Pressing the Space bar opens an instant preview, on by default unless another Space-bar previewer is installed [^3]. Images with an embedded ICC profile or a wide-gamut tag are converted into sRGB before display [^3]. It adds image dimensions, camera EXIF details and audio tags to Explorer's Details pane, hover tooltips and sortable columns [^3]. The makers say a corrupt or malicious file can't crash File Explorer, because it runs separately and reads files in a sandbox [^3]. ## Pricing and fees Neither Icaros's page nor SVG Explorer Extension's page states a price, so treat pricing as not published and read each project's page before paying anything. Neither rival states a card fee either, and no payment service is named for either tool. SageThumbs 2K is free for personal, noncommercial use under the PolyForm Noncommercial License 1.0.0 [^3]. Commercial use needs a licence for each installation: US$2.99 a month, or US$49 once for a licence that never expires and includes 12 months of updates [^3]. Business installs get a 7-day evaluation with every feature, after which thumbnails and previews stop until a licence key is entered [^3]. The licence is source-available, which means the code can be read but the noncommercial terms still apply [^3]. No card fee is stated. ## Getting started and everyday use Icaros's page lists a separate settings program, which requires .NET Framework 4 [^1], and which lets a user turn thumbnailing and properties on or off [^1] and set the cache size limit [^1]. Its core add-ons have no dependencies [^1]. It works on Windows Vista through 11 [^1], and version 3.0.3 and earlier work partially on Windows XP with thumbnails only [^1]. SVG Explorer Extension's page points out that the installer must match the system's architecture, since a 32-bit installer runs on a 64-bit system but the extension will not function [^2]. Its facts say nothing more about setup or daily use, so check its own page for install steps. SageThumbs 2K runs on Windows 11, with separate installers for standard PCs (x64) and ARM PCs (ARM64) [^3], and a portable zip that needs no admin rights [^3]. There is no separate app to open: thumbnails show up in Explorer folders [^3]. From the right-click menu a designer can convert, resize, rotate or flip images losslessly and combine them into a PDF or CBZ [^3]. Multi-file jobs such as resize and combine use every processor core [^3]. The right-click menu can be trimmed, reordered and regrouped [^3]. A command-line tool covers thumbnails, conversions and batch jobs [^3]. ## Things to check before you choose - Which systems do you work on? Icaros states Windows Vista through 11 [^1]; SVG Explorer Extension's page does not state systems, and SageThumbs 2K states Windows 11 [^3]. Check current requirements for each. - Do you need video thumbnails, SVG thumbnails, or both? Each tool alone covers a narrower set, so match the format you handle. - Will you use it for paid client work? Read each tool's licence terms for commercial use before installing on a work machine. - Do your exact file types show up? Test your own video, SVG, RAW and design files in each tool. - Is your machine 32-bit or 64-bit? SVG Explorer Extension needs the installer to match the architecture [^2]. - Do you want controls like a cache size limit or thumbnail on/off switches? Icaros lists them [^1] [^1]. ## How to choose - **You want video thumbnails for many media formats in Explorer:** Icaros [^1]. - **You want SVG thumbnails in Explorer:** SVG Explorer Extension [^2]. - **You want thumbnails and quick previews of design and CAD files right in Explorer:** SageThumbs 2K [^3] [^3]. - **You want Explorer properties alongside thumbnails for media files:** Icaros. - **You want to convert, resize or combine images into a PDF from Explorer:** SageThumbs 2K [^3]. - **You want wide-gamut images converted to sRGB for display in Explorer:** SageThumbs 2K [^3]. - **You use an older Windows, such as Windows 10 or 7:** Icaros states support from Vista through 11 [^1]; check each tool's current requirements. ## Frequently asked questions ### Is Icaros free? Icaros's own page does not state a price, so pricing is not published in the facts this page uses. Read Icaros's own page before paying anything or before using it for client work, since the fee and whether it covers commercial use are not stated. ### How much does SageThumbs 2K cost for business use? Commercial use of SageThumbs 2K needs a licence for each installation. It costs US$2.99 a month, or US$49 once for a licence that never expires and includes 12 months of updates [^3]. Business installs get a 7-day evaluation with every feature, after which thumbnails and previews stop until a licence key is entered [^3]. Personal, noncommercial use is free [^3]. ### Does Icaros show video thumbnails in Windows Explorer? Yes. Icaros's page says it can provide Windows Explorer thumbnails for essentially any video media format supported by FFmpeg [^1]. It also provides Explorer property details for many popular media filetypes. Thumbnailing and properties can each be activated or deactivated [^1]. ### Will the 32-bit SVG Explorer Extension installer work on a 64-bit computer? [[f:svg-explorer-extension-e338bd04]] Not as expected. Its page says the 32-bit installer will run on a 64-bit system, but the extension will not function [^2]. The installer must match the system's architecture, so choose the installer that matches your Windows version's bitness. ### Which Windows versions does each tool run on? Icaros's page states support for Windows Vista, 7, 8/8.1, 10 and 11 [^1]. SageThumbs 2K's stated platform is Windows 11, with separate installers for x64 and ARM64 PCs [^3]. SVG Explorer Extension's page does not state its systems, so check its own page. If you use older Windows, verify each tool's current system requirements before installing.
