ZenttraOps PDF Editor

Edit, stamp and merge PDFs. Convert JPG/PNG to PDF, PDF to images or text, with resolution controls. Works offline.

Edit, stamp, arrange, merge and convert PDFs on your computer. Choose Editor or Converter, select your files and download the result. Works offline, with no account, document upload or added watermark. EDIT AND MERGE • Edit existing PDF text directly on the page. Add text, images, shapes, highlights and drawings, or start with a blank page. • Adjust fonts, size, colour, opacity, alignment and spacing. Choose from 200 bundled font families plus three standard families, or load a TrueType font. • Arrange pages from several PDFs. Reorder, rotate, duplicate, remove, reverse or select a page range before downloading. • Download all arranged pages or only the selection. Use the combined source filenames or enter your own name and optional document details. • Preview at Fit width, Fit page or up to 300% zoom. Text and vector graphics stay in PDF form on export, and images retain their original pixel detail. CREATE AND REUSE STAMPS Create text stamps or import PNG/JPG images. Personalise text, font, size, colour, alignment, spacing, rotation, decorations and opacity. Select saved stamps from the Stamps dropdown and place them anywhere on a page. Placed stamps can move or be removed; edit their content in Manage stamps, then place a new impression. Your saved library stays on this device across browser closure, separately from Clear workspace. CONVERT OFFLINE • JPG/PNG to PDF: order your images and combine them into one PDF. Resolution sets the printed page size while preserving supported source pixels. • PDF to JPG/PNG: choose pages, format and 72, 150, 300, 600 or 1200 DPI. Multiple page images download together in a ZIP. • PDF to text: extract the existing text layer into a UTF-8 text file. 1200 DPI produces actual full-resolution page images, including standard A4 and Letter pages. Large exports need more memory. Oversized or failed conversions report an error rather than silently lowering resolution. Low-resolution scans cannot gain missing detail. Text extraction does not perform OCR or reproduce the original page layout. KEEP YOUR WORK Editor files, arrangement, document details, applied edits and unfinished editor drafts save in this browser for recovery. Let saving finish, then refresh the same workspace to recover the latest completed save. Separate workspace tabs remain independent. Clear workspace removes its recovery copy; saved stamps remain. Converter files and results are separate and kept only while the app tab is open. Download them before refreshing or closing. Saved work and stamps are not synchronized. Clearing extension data, uninstalling or browser storage eviction can remove local saves; download important results separately. PRIVACY Documents, images, fonts and entered content are processed locally. The extension does not upload documents, track browsing or use analytics. It requests no extension permissions. Website links open only when you select them. LIMITS AND COMPATIBILITY Editor: up to 50 source files, 200 MiB of retained source data and 1,000 pages. Stamps: up to 50 saved templates and 50 MiB total storage. Converter: up to 50 image inputs or one PDF, with 200 MiB input and output limits. Source images are limited to 40 million pixels; PDF image output to 150 million pixels and 16,384 pixels per edge. Encrypted, digitally signed or certified PDFs and some advanced forms are unsupported. Ordinary forms are flattened. Bookmarks, attachments, links and interactive actions are not preserved. Text reflow stays within the current page. Scanned text remains an image unless a text layer already exists. Check important documents after export. Version 1.3.1 adds offline conversion up to 1200 DPI, more preview detail at high zoom, and calmer workspace feedback.
