PDF and image converter — processed on your device

The six most common PDF and image tasks, running entirely in your browser: files are never uploaded to a server, which suits contracts, invoices, and internal paperwork. Converting Word, Excel, or PowerPoint to PDF, and compressing PDFs, are not included in this version yet.

How to use

  1. Choose an operation: image to PDF, merge PDF, split PDF, rotate pages, compress images, or convert image format.
  2. Drag files into the box or click to select; for merge PDF and image to PDF, reorder them with the up/down buttons.
  3. Adjust the options (page range, rotation angle, image quality), then click Process.
  4. Download the result and open it to check before sending it out.

Frequently asked questions

Are my files uploaded anywhere?
No. Everything runs on code inside your browser, so your files never leave your device. The PDF library is downloaded to your browser the first time you click Process. AdSys never receives or stores your files.
Can it convert Word or Excel to PDF?
Not in this version. Converting Office files needs a separate conversion server. For now, the fastest option is File → Save As → PDF inside Word or Excel.
Why won't a password-protected PDF open?
A password-protected PDF must be unlocked with a PDF reader first. The tool does not crack passwords.
Does compressing an image reduce quality?
Yes — compression trades file size for quality. 75–80% is usually hard to notice by eye; the tool shows the size before and after so you can choose.
