What you get
Everything runs on your PC. Nothing is uploaded.
Click any line in a PDF and retype it. RevinHi matches the original font, size and color, so the change blends in.
Type straight onto the page in wrapping text boxes. 6 fonts, bold, italic, underline, alignment, background, border and rotation, or match the text nearby.
Drop ✓ ✗ • ◯ ☑ marks that size themselves to checkboxes and lines, tick real form checkboxes, and sign with a saved signature. Flatten when you're done.
Highlight, underline or strike through selected text, leave sticky-note comments that show up in other PDF readers, and add stamps like Approved, Paid or Signed with the date.
Find with Ctrl+F, select and copy text, fit to width or page, two-page view, night reading and presentation mode. Bookmarks, clickable links, back/forward, and it remembers your place.
Drag pages to reorder, rotate, crop, duplicate, reverse, delete, extract or insert blanks. Copy pages between tabs, merge files and split by ranges.
Make scanned PDFs searchable and selectable without uploading them anywhere. It all runs on your PC.
Black out sensitive text and it's actually removed from the file, not just covered up.
Turn photos and scans into a PDF, or export pages as PNG / JPG at up to 300 dpi. Pro adds PDF to Word, PDF to text and extract images.
Process many files at once. Add page numbers, headers & footers, Bates numbering, custom watermarks and custom stamps, convert to grayscale, remove blank pages and flatten annotations.
Shrink image-heavy PDFs, often by 80% or more, and lock files with AES-256 passwords.
Command palette (Ctrl+K), a shortcut sheet, copy/paste/align/snap/lock objects, print, and autosave with crash recovery. Or run the portable version straight from a USB stick.
