PDF work often happens right before a deadline: combine attachments, split one page, rotate a scan, compress a document, or export pages as images. KitDevs groups these common actions into browser-based workflows.
Why uploading PDFs to cloud tools is risky
PDFs often contain contracts, invoices, IDs, HR documents, medical records, financial statements, or internal plans. Uploading a PDF to a cloud tool creates another copy outside your device. That may be fine for public documents, but it is not ideal for sensitive files.
KitDevs avoids that transfer. The browser downloads the app code, then the selected PDF is read and processed locally. This privacy model is the main reason to choose browser-based PDF tools.
KitDevs vs ILovePDF vs Smallpdf
ILovePDF and Smallpdf are established cloud PDF services with many features, account options, and server-side workflows. KitDevs is different in one narrow but important way: it focuses on local processing for common tasks. That means fewer server features, but no upload for supported workflows.
Choose a cloud tool when you need collaboration, OCR at scale, or server automation. Choose KitDevs when the task is supported locally and the document should stay on your device.
What runs in the browser
KitDevs uses pdf-lib for PDF writing tasks such as merge, split, rotate, and document creation. PDF.js handles rendering and text extraction. JSZip packages multiple output files into one ZIP when a tool produces several downloads.
These libraries are hosted with the site files and executed by the browser. They do not require a user account or a server-side file processing queue.
PDF workflow map
Start from the result you need. If the file is too large, compress it. If pages are in separate documents, merge them. If one document contains too much, split it. If a page needs to become an image, convert it.
| Goal | Tool | Output |
|---|---|---|
| Combine documents | Merge PDF | One PDF |
| Separate pages | Split PDF | ZIP of PDFs |
| Fix orientation | Rotate PDF | Corrected PDF |
| Make images | PDF to JPG | JPG files |
| Extract text | PDF to text | TXT file |
