A shared document workspace, with the right runtime for the job.
EVB Viewer opens local PDF, DjVu, and image files in the browser. The desktop app adds searchable-PDF OCR, native OS integration, and more room for large merge/export jobs.
Choose the right entry point
Start in the browser for quick local PDF, DjVu, and image work, or choose the desktop app for searchable-PDF OCR, native OS integration, and larger merges.
Web app
Best for opening local PDFs, DjVu files, and common images immediately, then reviewing, marking up, and exporting without installing anything.
- PDF, DjVu, and image workflows
- No install or updater friction
- Great for quick review, markup, page edits, and export
Desktop app
Best for searchable-PDF OCR, native OS integration, larger merge jobs, and workflows that need more than browser memory limits.
- Searchable-PDF OCR
- Larger merge and export jobs
- Native desktop dialogs and OS integration
Core workspace capabilities
Read, review, annotate, reorganize, and export documents in one workspace, then choose the runtime that fits the job.
PDF, images, and DjVu where it fits
Browser workflows open local PDFs, DjVu files, and common images. The desktop app adds searchable-PDF OCR and avoids browser memory caps on heavier jobs.
OCR with searchable output
Desktop builds run searchable-PDF OCR locally and keep the result inside the edited document.
Deep annotation tools
Highlight, underline, strike out, draw, place notes, and keep review work inside the file.
Page operations
Delete, extract, reorder, rotate, crop, and capture pages. Browser merges are capped for memory; desktop is better for large batches.
Workspace management
Use tabs, split layouts, bookmarks, search, and focused side panels instead of bouncing between tools.
Multiple export targets
Export to PDF, PNG, JPG, TIFF, and DOCX from the same workspace that handled review and edits.
How the product fits real work
A typical EVB Viewer session starts with quick browser work and moves to desktop when searchable-PDF OCR or scale requires it.
01
Start in the browser
Open a local PDF, DjVu file, or image immediately when installation would slow the task down.
02
Review and annotate
Search, comment, highlight, compare, and reorganize pages without leaving the workspace.
03
Move to desktop for OCR or scale
Install the desktop app for searchable-PDF OCR, native OS integration, and larger merge/export jobs.
04
Export the result
Save the outcome in the format the workflow needs instead of rebuilding the document somewhere else.
