Files, search and PDF
Browse, search and organise your files.
Litesum Library is the place your files are found: browse, search and organise your photos, videos and documents, with a built-in PDF reader, editor and converter, all on your own computer.

- Two programs
- The browser, and a PDF application in its own window
- PDF engine
- PDFium, built into the application
- Graphics card
- None required. Library deliberately uses no GPU.
What it does
What you can do with Library.
Browse a folder the moment it opens
Nothing is indexed before you can look: a folder lists live, with drives and a folder tree beside it.
Open a PDF in its own window
A PDF opens in a separate Litesum Library PDF application rather than a tab in the browser, with page navigation, zoom, fit width and fit page. A second document joins the same window as a tab, not a second process.
The PDF window stands on its own
Close the browser and your PDF stays open in its own window, exactly where you left it.
Convert PDF pages to PNG or JPEG
Convert ▸ To Image, or Ctrl+Shift+I, writes the pages you choose at the resolution you choose.
Open a file from the command line
Given a path, Library starts on that file, selected in its folder.
Files
What it opens and what it saves.
| Format | Opens | Saves | Notes |
|---|---|---|---|
| Yes, in its own window | Pages as PNG or JPEG | Reading with navigation, zoom and fit. Convert ▸ To Image writes chosen pages at a chosen resolution. | |
| Images, video, audio, RAW, documents | Listed with their properties | — | Every file is listed with its kind and properties and can be shown in File Explorer or opened with the system's application. |
Requirements
What you need to run it.
- Operating system
- Windows, 64-bit.
- Graphics
- No graphics card required.
When a membership ends
Your work stays. Come back any time.
Your files and programs stay right where they are, ready whenever you’re ready to resubscribe. Or simply uninstall. The decision is always yours.
Membership
Litesum Library is included in Litesum Complete.
Planned at £9.99 per month for every released Litesum application, 6 launching together, on 2 computers, cancellable from your account page. Everything you open, edit or export stays on your own computer. It is never uploaded, never used for training and never held behind a subscription.
Does Library develop RAW photographs?
No. Library browses the folders you already have and lists every file in them, RAW files included; developing a RAW photograph is Photo's job.
Does it have to index my whole drive before I can use it?
No. Browsing is live from the first moment you open a folder.
Will it delete duplicates for me?
Never automatically. Deleting a file is always a distinct, explicit action of your own.
Does anything leave my computer?
No. Browsing, PDF reading and conversion all run on your own computer.
When will Litesum Library be available?
Litesum Library launches with the rest of the suite on Litesum Complete.
Will it be included in Litesum Complete?
Yes. One membership covers every Litesum application at no extra cost.
