HEIC to PDF converter for iPhone photos of documents
You photographed receipts, a signed form or handwritten notes on your iPhone, and the office wants a PDF. Send the HEIC photos to your todo.is agent: it converts them, crops each page to the paper, makes the text readable and returns one PDF in the right order.
The prompt
- Make a PDF from the attached iPhone HEIC photos: [ATTACH THE HEIC PHOTOS]. These are [WHAT THEY ARE]. Put them in the order [ORDER], one per page on [PAGE SIZE]. Crop each photo to the paper edge, turn it upright and make it look like a clean scan ([COLOUR MODE]). Add searchable OCR text. Keep the PDF under [SIZE LIMIT] and name it [FILE NAME].pdf.
What to change
- [ATTACH THE HEIC PHOTOS]: Attach the .heic photos. Send them as files from the Files app or as documents in WhatsApp to keep them sharp.
- [WHAT THEY ARE]: E.g. "travel receipts for an expense claim", "a signed rental form" or "lecture notes".
- [ORDER]: E.g. "by date taken" or "as numbered on the pages".
- [PAGE SIZE]: E.g. "A4" or "Letter".
- [COLOUR MODE]: E.g. "black and white like a scan" for text, or "colour" for receipts with stamps.
- [SIZE LIMIT]: E.g. "4 MB".
- [FILE NAME]: E.g. "Expenses_Berlin_Trip_Oct".
Example result
- HEIC to PDF: Berlin trip receipts
- 11 iPhone photos · 11 A4 pages · colour · searchable · 1.6 MB
- Pages, by date taken
- • 1. Taxi, airport to hotel · 6 Oct
- • 2. Hotel deposit slip · 6 Oct
- • 3. Lunch with client, Café Anker · 7 Oct
- • 4. Train ticket, Berlin to Leipzig · 7 Oct
- • …
- • 11. Hotel final bill · 9 Oct
- What happened to each photo
- • HEIC converted with the colour profile kept
- • Cropped to the receipt edges, removing the desk and your fingers
- • Straightened the receipts photographed at an angle and turned 3 sideways photos upright
- • Brightened and raised contrast so thermal paper print is readable
- • Centred on an A4 page with a small margin, so it prints like a scan
- Searchable text
- Each page has an OCR text layer, so the finance team can search "VAT" or copy totals. Faded thermal receipts can come out with errors, so the image is what counts.
- Totals (from OCR, please check)
- Your agent also read the totals: 11 receipts, 486.30 EUR. Ask for an Excel expense sheet with date, vendor, amount and VAT per receipt if your claim form needs one.
How to do it with todo.is
- Copy the prompt and describe the documents, order and colour mode.
- Attach the HEIC photos in todo.is or send them to your agent on WhatsApp as documents.
- Your agent converts, crops and orders them, then returns one searchable PDF.
- Reply with fixes such as "page 5 is too dark" or "split into one PDF per receipt".
Tips for a better result
- Put receipts on a dark surface when you photograph them. The paper edge is easier to find and crop.
- Thermal receipts fade. Convert and send them soon after the trip.
- Black and white mode makes text documents look like a real scan and keeps the file small.
- Ask your agent to remember your expense format. Next trip, just send the photos.
HEIC to PDF converter: FAQ
- How do I convert iPhone photos to one PDF? Attach the HEIC photos and say the order. Your agent converts them and puts one per page in a single PDF.
- Can it make photos look like a scan? Yes. It crops to the paper, straightens, and cleans the background in colour or black and white.
- Will the PDF be searchable? Yes, an OCR text layer is added. Faded or crumpled pages can have reading errors.
- Do I need to convert HEIC to JPG first? No. Your agent reads HEIC directly and converts it as part of building the PDF.
