Tips for best results

PDF to Word: PDFs with selectable text convert far better than scanned documents. Scanned PDFs need OCR for editable output.
Reduce image size: Convert JPG or PNG to WebP to reduce file size by 25–35% with no visible quality loss — ideal for websites and email.
Images to PDF: Use JPG to PDF to combine multiple images into one document — great for sharing photo albums or scanned paperwork.
Compress PDF: Use Compress PDF before emailing large files. Typically reduces size by 30–60% with no visible quality change.
