ZenttraOps PDF Merger

Edit PDF page content, combine files, and choose exactly which page comes first, next, and last. Add your PDFs, follow local reading and processing progress, preview their pages, and drag pages into the order you need. Move selected pages to an exact position, rotate pages, duplicate them, remove unwanted pages, or reverse their order. Select individual pages, ranges, odd pages, or even pages. Undo and redo let you revise your edits. Full-page previews, the editor and stamp placement previews render at the current zoom and screen pixel density. Preview and editing open at Fit width; use Fit page for the whole page or zoom in to inspect details. The larger responsive page preview offers 100–300% zoom with scrolling. Rendering remains bounded for unusually large pages. Text and vector content stay in PDF form at export. Original images keep their source pixels; low-resolution scans cannot gain missing detail. Download the complete workspace as one PDF, or download only the selected pages. Reuse one of the source filenames or type a custom filename, and optionally add a document title and author. Page sizes, text, and vector content stay in PDF form without converting each page into an image. Use Stamps to create reusable text stamps with 200 searchable offline font families plus three standard fonts, size, colour, alignment, line spacing, rotation, underline, strikethrough and opacity controls, or load a PNG/JPG stamp. Standard fonts also support bold and italic; catalog fonts use their original supplied face. Save favourites on this device and click anywhere on a page to place them. A wooden stamp shows the selected text, then presses and lifts after placement; reduced-motion preferences disable this animation. Text stamps remain vector text, and image stamps keep at least 300 effective DPI when placed or resized. Move, resize and edit placed content with the page controls. Multiline text stamps create separately editable lines. Delete saved templates independently of stamps already placed in PDFs. Open Edit page, click existing text and type directly on the page. Keep font, size, colour and other formatting controls in the sidebar, and add formatted text. As horizontal text expands, lower content moves down when needed, with live spacing previews and undo. Separate columns remain in place unless they conflict with the expanded text. Use built-in fonts or import a TrueType font. Insert images and shapes, adjust shape appearance directly without an update button, draw on the page, move or resize content, and use undo and redo. Apply changes to return to the workspace. Blank page creates an A4 page for new content. Downloads have no added watermark. Click the extension icon to open the workspace, add your PDF files, arrange the pages, and download the result. Check the downloaded file before sharing it. Colour pickers include presets, hex/RGB controls and optional screen colour sampling. Close them with Done, Escape or a click outside while keeping colour changes applied. Leaving a page with edits opens a confirmation dialog. Keep editing is selected by default; Escape returns to editing, and Discard edits explicitly abandons the page changes. Your documents are processed on your computer. No upload, account, analytics, or website access is required. The extension works offline once installed. The PDF workspace is kept only while its tab remains open; download your result before closing or refreshing the tab. Only stamps you explicitly save remain locally for reuse. Supports up to 50 source files, 200 MiB of source data, and 1,000 pages per workspace. Save up to 50 stamps, with 50 MiB total local stamp storage. Encrypted PDFs, digitally signed or certified PDFs, signature fields, and some advanced forms are not supported. Ordinary form fields are flattened for export. Document bookmarks, embedded attachments, links, and interactive actions are not preserved. Scanned images stay images unless text is added to the page.
