Crimson Pdf vs PDFWorldEditor

Crimson Pdf is the everyday PDF toolkit for iPhone and iPad. Convert, scan, sign, edit and protect documents — all 100% on-device. Nothing uploaded, nothing tracked, completely free with no in-app purchases or ads. Whether you're sending an invoice from a coffee shop, signing a lease before a viewing, or compressing a 200-page report for email, Crimson handles it in seconds. Powered by Apple's native PDFKit, VisionKit and PencilKit frameworks for instant offline processing. ■ CONVERT — 10 TOOLS Turn PDFs into Word (DOCX / RTF), Excel (XLSX), PowerPoint (PPTX), images (JPG / PNG), plain text and CSV. Convert back the other way: images, Word (.docx / .doc / RTF / HTML / TXT), Excel spreadsheets and PowerPoint slides into clean PDFs. ■ SCAN & OCR Snap any printed page with the built-in scanner — auto edge detection, perspective correction, multi-page output. Extract searchable text from photos and PDFs using Apple's on-device Vision framework. Nothing is sent to a server. ■ SIGN & ANNOTATE Draw your signature with Apple Pencil or finger using PencilKit, then stamp it onto any contract. Highlight, add sticky notes, and erase — all with precise tap targeting on the page. ■ ORGANIZE Merge, split, rotate, reorder pages. Compress to shrink a 10 MB PDF down to ~1 MB before sharing. Lock with a password. Add page numbers (1, 1/12, or Page 1 of 12 styles) and watermarks for confidential drafts. ■ FORMS Detect and fill PDF form fields automatically. Save filled copies without flattening so you can edit later. ■ DESIGNED FOR iOS Built entirely with SwiftUI for iOS 17 and above. Clean light theme, smooth gradient animations, haptic feedback, dynamic type and accessibility support. Files surface in the iOS Files app — no walled garden. ■ PRIVACY FIRST — NO DATA COLLECTED Every conversion, scan and OCR pass runs on your device. No cloud uploads, no analytics, no tracking, no third-party processing. Crimson Pdf makes zero network requests for its core functionality. ■ MULTI-LANGUAGE Available in 17 languages: English, Vietnamese, Spanish, French, German, Portuguese (Brazilian & European), Arabic, Hindi, Bengali, Indonesian, Japanese, Korean, Russian, Turkish, Chinese (Simplified & Traditional). Crimson Pdf is completely free. Every tool is unlocked from day one — no ads, no subscriptions, no in-app purchases.

PDFWorldEditor opens, reads and transforms your PDF documents right from your phone. WHAT YOU CAN DO Read. Open a PDF, scroll, zoom, jump to any page. Annotate. Highlight, draw, write on a page, add a note. Sign. Draw your signature once, place it wherever you want, and reuse it on your next documents. Assemble. Merge several PDFs into one. Reorder pages, rotate them, delete them. Create a blank document and insert a photo. Compress. Reduce the size of a file too heavy to send by email. Convert. Turn a PDF into an editable Word document, or into images. Scan. Photograph a sheet of paper: the image is straightened, the text is recognised, and you get a PDF you can search for a word in. Edit text. Tap a word in an existing PDF and replace it. Useful for correcting a date, an amount, a name. Print and share. Send the document wherever you want with your iPhone's share sheet. WHAT THERE IS NOT No account required: everything works without signing in. Signing in is optional, with Apple or with Google. It only serves to recognise you: your documents are never attached to an account. No advertising. No subscription, no in-app purchase. No tracker, no analytics. YOUR DOCUMENTS Reading, annotating, signing, merging and reordering pages all happen entirely on your iPhone, offline. Four features need computing power the phone cannot provide on its own: compress, convert, scan and edit text. They send the document to our server in Germany for the time of the computation. We have neither a database nor storage space: the file is not kept after the response. Everything is explained in detail in our privacy policy. App published by HYVRAX, a French company.
