A while back, I was chatting with friends who needed to submit documents to Home Office. What surprised me was how many of them were using free online tools to handle PDFs containing bank statements, salary slips, and address proofs.
These weren't careless people, they just didn't realise what happens when you upload a PDF to a "free" website. Your files pass through someone else's server. Your personal data like account numbers, addresses, income details all ends up who-knows-where.
When someone need to merge two PDFs or reorganise pages in a PDF, they usually search online for the "best" way and click the first result. It's convenient. But convenience shouldn't mean giving away your privacy.
So I built PDF Toolbox. Everything runs locally on your device. No uploads. No servers. No accounts. Just you and your documents.
This is a complete rebuild of PDF Unlocker, which only removed PDF passwords. With the new name: PDF Toolbox now includes 17 professional tools:
Organize
- Merge multiple PDFs into one
- Split PDFs into separate files
- Rotate, reorder, extract, or delete pages
Optimize
- Compress PDFs to reduce file size
- Resize pages to different dimensions
- Flatten tools to produce a static, non-editable PDF where all visual elements are permanent and indistinguishable from original content
Create & Convert
- Convert PDFs to images (PNG, JPEG)
- Create PDFs from photos or scanned documents
- Make scanned documents searchable with OCR
- PDF to PDF/A Converter
Secure
- Unlock password-protected PDFs
- Add password protection
- Remove metadata (author, dates, edit history)
Edit
- Add watermarks
- Insert page numbers
- Sign PDF documents
The app use Apple's native PDFKit and Core Graphics. No third-party libraries touching your documents.
