PDF Tools
Choose whether you need to reduce an existing PDF, turn ordered images into pages, or join several documents. All three workflows run locally and report the resulting page count and bytes.
Available tools
PDF Compressor
Run a conservative structure pass on one unrestricted document and compare the result; image-heavy PDFs may need changes in the source application instead.
Open tool →PDF ToolsImages to PDF
Build a PDF from ordered JPG or PNG files, with controls for page size, orientation, margins, rotation, and how each image fits.
Open tool →PDF ToolsMerge PDF
Review the order of several valid, unrestricted PDFs before copying their pages into a single document on this device.

Already have one PDF that is too large? Try PDF Compressor and compare the measured output; scans may need a new export from the source application. Have separate JPG or PNG pages? Images to PDF lets you set page order, rotation, margins, and contain or cover. Have multiple PDFs? Merge PDF copies their pages in the order shown.
After any PDF workflow, open the downloaded document, count the pages, and inspect page order and legibility. The PDF-specific checks are in the practical guide.
What survives a PDF operation?
| Operation | Suitable use | What to inspect |
|---|---|---|
| Compress PDF | Rewrite the structure of a regular, unrestricted PDF. | Output bytes, every page, links, and form behavior. Scanned image resolution is not reduced. |
| Images to PDF | Place JPG or PNG images on new pages. | Page order, crop, margins, rotation, and readability. No OCR text layer is created. |
| Merge PDF | Copy pages from multiple unrestricted documents. | Interactive fields, bookmarks, attachments, and other document-level features may not carry across. |
Keep digitally signed originals. Rewriting or combining documents cannot preserve their original signature validity. Files with a detected signature are rejected; detection is not a signature-verification service. Never use the result to imply that a signature remains valid.
