Free Online PDF Tools
Edit PDFs without ever uploading them.
Your files never leave your device. No upload. No sign-up.
Every PDF tool on this page runs entirely inside your browser. Your documents are opened, edited and re-saved on your own device using pdf-lib — they are never sent to a server, never stored, and never seen by us. That makes SwiftTooly's PDF toolkit a safe choice for contracts, payslips, medical forms and anything else you'd rather not hand to a stranger's web server.

Browser-based vs upload-to-server
SwiftTooly (browser)
Files are decoded in JavaScript with pdf-lib, edited in memory, and re-saved through your browser's download dialog.
Typical upload-to-server tools
Files are uploaded to a third party, processed on their machines, cached on disk, and returned over the network — often with size limits, daily caps or a watermark.

Frequently asked questions
- Are my PDFs really not uploaded anywhere?
- Correct. The PDF tools here use the pdf-lib library running inside your browser tab. Open your browser's network inspector and you'll see no request leaves your device when you merge, split, compress or rotate a file.
- Is there a maximum PDF size?
- There is no hard limit, but very large PDFs (hundreds of MB) depend on how much memory your browser can allocate. Most modern laptops handle multi-hundred-page documents comfortably.
- Will the output PDF keep its fonts, signatures and form fields?
- Pages are copied byte-for-byte, so embedded fonts, vector graphics, images and visible form content are preserved. Interactive form fields and digital signatures may be flattened depending on the operation.
- Can I use these PDFs commercially?
- Yes. SwiftTooly never claims any rights over your content. The processed PDF is yours to use exactly as you would have used the original.
- Why doesn't SwiftTooly add a watermark?
- Because we're not trying to upsell you into a paid plan. Every tool is free, unlimited, and free of branding inside your output files.
