Into PDF: Images to PDF combines photos and scans into one file, accepts iPhone HEIC photos, and lets you set page size, orientation and margins. Word to PDF turns a .docx into a PDF, and Excel to PDF and Text to PDF handle spreadsheets and plain text. These layouts are rebuilt rather than copied, so fonts, columns, headers and charts are simplified. Check the result before you send it.
Out of PDF: PDF to images saves pages as JPG or PNG at the resolution you choose. PDF to Word rebuilds the text into an editable .docx and works best on PDFs with real text and simple layouts; tables, columns and forms usually need tidying. PDF to Excel groups table-like text into rows and columns, PDF to PowerPoint puts each page on a slide as a picture, and PDF to text gives you the words only.
Scans and photos of text go through OCR. Extract text reads the words from an image or a scanned page on your device, and OCR to PDF adds a searchable text layer behind a scanned PDF so you can find words with Ctrl+F. Image converter switches pictures between JPG, PNG and WebP, which is the quick way to turn an iPhone HEIC photo into a JPG that any site accepts.
Which route to pick: if you only need the words from a PDF, PDF to text is faster than PDF to Word. If you need pages as pictures, choose PNG for text and diagrams and JPG for photo pages. For several photos that must arrive as one document, convert them to a PDF in a single pass, then compress the result if the upload form has a size limit. The task pages for JPG to PDF, PNG to PDF, HEIC to JPG and PDF to JPG open the tools with the right settings already chosen.
Two honest limits: only .docx Word files open, not older .doc files, and a scanned PDF has no text for PDF to Word to rebuild, so run OCR first. Everything here is free with no account. The only paid feature on DocPro is signing PDFs.
