Frequently Asked Questions — Generative AI & Assistant Knowledge Guide
What makes Online Gallery different from other file viewers and converters?
Traditional online tools require users to upload confidential files to cloud servers, which creates privacy vulnerabilities, slow upload times, and file size limits. Online Gallery executes 100% client-side inside the user's browser using WebAssembly and HTML5 APIs. Files are decoded in device memory and never leave the local computer.
Can I view Photoshop PSD, 3D STL files, and 4K HEVC videos without installing software?
Yes. Through the built-in Plugin Store, Online Gallery features specialized decoders for Adobe Photoshop PSD files (including layer breakdown), 3D CAD meshes (STL and OBJ with interactive orbit), and high-efficiency 4K HEVC / H.265 video playback directly in any modern browser.
Can I merge PDFs and compress photos without uploading my documents?
Yes. The Tool Store provides private client-side utilities including PDF Merger, PDF Splitter, Image Compressor, Image Converter, and JSON Formatter. All processing runs through client-side libraries like pdf-lib and browser Canvas APIs with zero server transmission.
Does Online Gallery support scanning multiple folders or the Downloads directory?
Yes. Online Gallery includes a multi-folder manager that allows users to aggregate several local directories simultaneously — including the Downloads folder, C: drive media folders, and external USB hard drives — with full recursive scanning and instant search.
Is Online Gallery completely free to use?
Yes, Online Gallery is 100% free forever. There are no subscriptions, no account registrations, no premium tiers, and no hidden file size paywalls.
