ZenttraOps PDF Editor

Edit PDF text, add stamps and drawings, arrange pages and merge multiple PDFs into one document. Works offline.

Edit, stamp, arrange and merge PDFs on your computer. Choose the pages you need, put them in order and download the result. No account, upload or added watermark. Arrange your PDF • Import PDFs by clicking the empty drop area or dragging files into the workspace. • Preview pages, drag them into order or move selected pages to an exact position. • Rotate, duplicate, remove or reverse pages. Select individual pages, ranges, odd pages or even pages. • Download all pages or just the selection. The filename combines included source names in page order, or you can enter a custom name. Add an optional title and author. Edit page content Click ordinary PDF text to edit it directly. Use the four-arrow handle to select and delete the whole item. Add text, images, shapes and drawings, or start with a blank A4 page. Adjust fonts, size, colour and opacity; use common font-size presets or enter a custom size. Expanding horizontal text can move lower content down within the current page. Undo and redo help you review changes before applying them. Create and reuse stamps Create text stamps or import PNG/JPG images. Choose from 200 searchable offline font families plus three standard families, with controls for size, colour, alignment, line spacing, opacity, rotation, underline and strikethrough. Standard families also support bold and italic; catalog fonts use their supplied faces. Font menus preview available typefaces. Save templates in Stamps and choose one from the dropdown for direct placement. Your saved library stays on this device across browser closure. Clear workspace leaves the library intact; delete templates separately in Manage stamps. A wooden-stamp preview shows the selected text and animates placement, respecting reduced-motion settings. Newly placed stamps can be dragged or moved with arrow keys, or removed. Their text, style, size and rotation stay locked in this editor. Multiline text and decorations move together. Edit a template in Stamps and place a new impression; existing impressions do not change. Clear previews and native PDF output Preview and editing open at Fit width. Use Fit page or zoom to inspect details. Page and editor previews render at twice the screen pixel density, within memory limits for large pages and high zoom. Text stamps remain vector text, and image stamps are limited to a placement size that preserves at least 300 effective DPI. PDF text, drawings and vector content remain in PDF form on export, and images retain their original pixel detail. Low-resolution scans cannot gain missing detail. Automatic local recovery PDFs, page arrangement, metadata, applied edits and unfinished editor drafts automatically save in local browser storage. Let saving finish, then refresh the same workspace to recover the latest completed save. Separate workspace tabs remain independent. Clear workspace removes that workspace's recovery copy and resets its filename and document details to blank. Page-editor undo history resets after recovery; current edits and drafts remain. The extension works offline once installed. It requests no extension permissions and does not upload documents, track browsing or use analytics. Saved work and stamp templates are not synchronized. Storage failures are shown; clearing extension data, uninstalling or browser storage eviction can remove local saves. Download important results for a separate copy. Limits and compatibility Up to 50 source files, 200 MiB of source data and 1,000 pages per workspace; up to 50 saved stamps with 50 MiB total stamp storage. Encrypted, digitally signed or certified PDFs, signature fields and some advanced forms are unsupported. Ordinary forms are flattened. Bookmarks, attachments, links and interactive actions are not preserved. No OCR: scanned pages remain images. Text reflow stays within the page and rejects changes that would overflow or move a stamp. Check important documents after export.
