🛠️ Top five tips to use AlterPDF effectively

Save images from a PDF: If you’ve scanned documents to PDF, you can extract the images separately with "Extract Images". It’s an easy way to reuse or analyze graphics.

Back up as images: Use "Convert PDF to Images" to save the entire PDF as high-resolution images. Ideal for archiving, sharing, and viewing without a PDF reader.

Combine attachments with Merge PDF: If you have multiple PDFs, e.g., receipts or contracts, you can quickly combine them into a single file with "Merge PDF".

Extract text as TXT: Use "Extract Text" to convert a PDF’s content into a simple text file you can edit in Notepad, Word, or any other text editor.

Encrypt your files: Sending sensitive information? Use "Encrypt PDF" to protect your documents with a password so unauthorized users can’t read them.
