Carpathron PDF Editor

Everything you do with PDFs, in one app
Edit with the original fonts
Click a paragraph and type. The app recognises the document's fonts and uses them, or the closest installed or built-in font with the same widths, so the page keeps its look.
OCR for scans and photos
Scanned pages become real text in a matching font and size, or a searchable layer under the picture. English, Romanian, Italian, French, Spanish and German, on your PC.
Comments and review
Highlights, notes, text boxes, callouts, stamps, drawings and measurements, with replies and a comment list you can export.
Pages and files
Tabs for several documents, merge files of any kind, split, extract, insert, rotate, crop, page numbers, Bates numbers, headers, watermarks and bookmarks.
Forms and signatures
Fill in and create forms, find fields automatically, fill from a CSV, sign with your hand-drawn signature or with a certificate, and check signatures.
Protect and clean
Passwords and permissions, true redaction (also of e-mails, phone numbers and IBANs), and a scan that finds earlier versions, metadata and hidden text — run it again to see that they are gone.
Convert and compare
To and from Word, Excel, PowerPoint, HTML, text and images; compare two versions and get the changes as a Word file with tracked changes.
Your own cloud
Open and save on Google Drive, Dropbox, OneDrive, FTP, SFTP, WebDAV (Nextcloud and others) or S3 storage with your own account. Files go directly between your PC and your storage.
AI assistant with your own key
Ask questions about the document, summarise or translate it with Claude, ChatGPT, Gemini, Meta AI, Mistral, Groq, DeepSeek, Grok, OpenRouter or a local Ollama model. You add your own API key; it is stored encrypted on your PC and the text goes straight to the provider you chose.
Batch and automation
Process many files at once, watch folders and treat every new file automatically, or run the app from the command line.

Questions
What do I need?
Windows 10 or 11 (64-bit), macOS 12 or later (Apple silicon or Intel) or 64-bit Linux. The app, the OCR languages and the fonts are included; no account is needed to read PDFs.
What is free?
Reading, searching, printing, filling in forms, opening from your cloud and checking signatures are free, without a time limit. Editing, OCR, conversions and the other tools need a license.
Can I try the editing tools first?
Every editing tool is free to try for 3 days on each PC, counted from the first start. After that, reading stays free and editing needs a license.
How is the license counted?
One license per PC where you edit. Buy as many PCs as you need in one order; longer plans cost less per month.
How do I activate it?
Open Carpathron PDF Editor, click Plans (bottom right, or Tools → Plans), paste the key and press Activate. To move it to another PC, press Release this PC first.
Does it need the internet?
Only to start the trial, to activate the license and to check it every few days. Your documents never leave your PC, except when you open or save them in your own cloud or ask the AI assistant, which sends the text to the AI provider you chose.
Which clouds can I use?
FTP, FTPS, SFTP, WebDAV (Nextcloud, ownCloud, Synology, Box, pCloud) and S3-compatible storage work at once with your login. Google Drive, Dropbox and OneDrive work through their sync folders, or directly with your own free app ID from Google, Dropbox or Microsoft (the app explains the steps).
How do renewals work?
Monthly to yearly plans renew automatically through PayPal; you can stop the renewal any time in your account and the license keeps working until the end of the time you paid for. The 2-year plan is one payment.
Can I get an invoice?
Yes. Write to contact@qubitpage.com with your order number and your company details.
