KillerPDF v1.7.5

KillerPDF is a lightweight PDF conversion and document processing application that focuses on simplicity, speed, and privacy. Instead of relying on cloud-based services, it performs PDF operations locally on your computer, allowing you to convert, merge, split, compress, and manage PDF documents without uploading sensitive files to external servers.

For users who frequently work with confidential documents, KillerPDF offers a practical alternative to online PDF tools.

Many online PDF services require users to upload documents before processing them. While convenient, this approach may not be suitable for business documents, contracts, invoices, or personal files.

KillerPDF addresses this by processing documents locally whenever possible. This reduces privacy concerns while also eliminating the need to wait for files to upload and download.

The application is designed with a straightforward interface that emphasizes common PDF tasks over complex editing features.

Key Features of KillerPDF

PDF Conversion

KillerPDF supports converting documents between PDF and various file formats, making it easier to work with reports, presentations, and office documents.

The conversion process is simple and requires only a few steps.

Merge PDF Files

Users can combine multiple PDF files into a single document.

This feature is useful for creating reports, assembling scanned documents, or organizing related files into one PDF.

Split PDF Documents

Large PDF files can be divided into smaller documents or individual pages.

This makes it easier to extract specific sections without modifying the original file.

PDF Compression

The built-in compression tool helps reduce PDF file sizes while maintaining acceptable document quality.

Smaller files are easier to email, upload, and archive.

Local Processing

One of KillerPDF's strongest advantages is local document processing.

Keeping files on your own computer improves privacy and may also speed up processing for large documents since there is no need to transfer files over the internet.

Easy-to-Use Interface

The application focuses on essential PDF tools with a clean interface that is suitable for beginners.

Most operations require only selecting a file, choosing the desired action, and saving the result.

KillerPDF v1.7.5 Release Notes:

KillerPDF 1.7.5 is a small maintenance release that closes several visible annotation, scrolling, shortcut, theme, and localization regressions. It keeps the faster scrolling introduced in 1.7.4, makes Transform trustworthy with freshly placed text, and gives the text annotation toolbar a cleaner two-row layout.

Added

  • Shift+mouse wheel now scrolls wide pages horizontally, using the same scrolling path as a tilt wheel (#209, thanks Ryokoxx).
  • Ctrl+B, Ctrl+I and Ctrl+U now bold, italicize and underline while you are editing a text box. They were listed in the shortcuts for weeks without ever being wired up.
  • Hungarian OCR completes the twelve-language OCR catalog, so every language available for the KillerPDF interface now has a matching downloadable recognition model.

Changed

  • The text annotation toolbar now uses a deliberate two-row layout: font above size, text color above fill color, and text opacity above fill opacity. It is taller but substantially narrower, with each lower control aligned beneath its corresponding upper control instead of leaving Fill Opacity stranded on an accidental wrapped row.
  • The sidebar moved from Ctrl+B to F9, and moving it left or right from Ctrl+Shift+B to Shift+F9. Ctrl+B was documented as bold and as the sidebar at the same time, and it was the sidebar that answered. F9 was the one function key with nothing of its own to do: the four view modes still have F5 to F8, and the wheel over the view still cycles them.
  • The current-page span badge now casts a small shadow beneath its rectangle, while its text remains independently rendered and crisp. The 98SE theme keeps the badge flat with the rest of its classic chrome.

Fixed

  • Rotating a page now keeps upright text boxes, images, and signatures inside the new page bounds. Their centers still follow the rotated sheet, but an item near the old long edge is clamped before it can become invisible and unrecoverable off-page (#169, thanks terada-d).
  • Fast wheel scrolling in Single Page and Two-Page views no longer carries its remaining momentum into an accidental page change at the edge. Scrolling keeps its existing speed; changing pages requires a deliberate second wheel gesture (#205, thanks 1mk3r).
  • Transform now commits an active text box before building its preview, so text placed immediately before opening Transform is included in both the preview and the transformed page.
  • Grid zoom now updates every page seam in one layout pass, so the pages no longer resize first and then visibly settle one border at a time as their refreshed bitmaps arrive.
  • Switching themes, accents, or languages with an annotation or crop bar open now rebuilds that bar completely in both split panes. This fixes controls retaining colors from the previous theme, including the light-theme mismatch, and keeps code-built crop labels, tooltips, and buttons current without reopening the tool.
  • Nine dialogs, including the install and update prompts, now preserve their intended line breaks. The strings carried the breaks but not the attribute that stops XAML collapsing them, so adding more had no effect (#231, thanks bovirus).
  • Shortcut key and mouse names, including Ctrl, Shift, Home, End, Delete, Click and Scroll, are now translatable in all twelve languages. The list and visual keyboard are generated from one shared table, fixing the missing Alt+M entry and inconsistent navigation descriptions while preventing the two views from drifting again (#230, thanks bovirus).
  • Shared dialog buttons now translate OK, Cancel, Yes, and No, including the custom color picker (#227, thanks Mr-Update).
  • Recent files now translate the missing label instead of leaving it in English (#227, thanks Mr-Update).
  • Annotation copy, paste, and delete confirmations now use the active language and the correct singular or plural message (#227, thanks Mr-Update).
  • Search now translates its empty, error, summary, navigation, and close messages. Its result field is wider so longer translated states are not clipped (#227, thanks Mr-Update).
  • OCR model downloads now translate their progress and cancellation hints, including multi-model downloads, and flatten/export progress is translated as well (#227, thanks Mr-Update).
  • The portable launcher now publishes cleanly with the .NET 10 SDK without trying to copy an unused binding-redirect configuration file.
