🔧 Powerful PDF Editing Tools

📄 Merge PDF
Combine multiple PDFs into one file in the order you choose. Drag to reorder; password-protected files must be unlocked before merging.

✂️ Split PDF
Extract pages by range or export selected pages to a new PDF. Use range notation to keep exactly what you need.

🗑️ Delete Pages
Select unwanted pages in a grid and remove them to trim your document quickly.

🔀 Rearrange & Rotate
Drag to reorder pages; rotate pages in bulk to fix scan or photo orientation.

🗜️ Compress PDF
Multiple compression levels (Basic / Recommended / Strong) to balance file size and visual quality.

⚫ Grayscale
Convert color PDFs to black and white—great for printing or smaller file size.

🔧 Repair PDF
Try to rebuild the index and cross-reference table of damaged or incomplete PDFs to restore accessibility.

🔄 Convert & Extract

📷 Images to PDF
Create PDFs from JPG, PNG, or WEBP; reorder images and choose original aspect ratio or A4 layout.

🖼️ PDF to Images
Export pages as PNG or JPEG with multiple quality levels and per-page selection.

📦 PDF to ZIP
Package each page as a separate PDF file inside one ZIP archive.

🖼️ Extract Embedded Images
Export embedded image assets from the PDF and save them as a ZIP.

📝 PDF to Text
Read the PDF text layer and export a .txt file or copy to the clipboard (scanned documents without a text layer may not yield text).

📋 Edit Metadata
Edit title, author, subject, keywords, and other properties; set a default author in Settings.

⚡ Batch Processing
Run the same action on multiple PDFs (e.g. batch compress)—process in one go and review results file by file.
