When to turn images into a PDF

  • Applications and forms: combine photos of ID, certificates or receipts into the single PDF many forms ask for.
  • Homework and notes: turn phone photos of pages into one document that's easy to submit.
  • Portfolios: share a set of images as one file that opens the same on every device.

Tips for a clean, readable PDF

  • Photograph documents in good light, straight on, and fill the frame.
  • Use a small margin for documents that may be printed, so nothing gets cut off.
  • If a form has a size limit, choose "Smaller file", or compress the images first with the image compressor.

Frequently asked questions

How do I combine several JPGs into one PDF?

Add all the images at once, arrange them in the order you want, and click Create PDF. You get a single PDF with one image per page.

How do I make the PDF smaller?

Choose "Smaller file". Large photos are scaled to a maximum of 2000 px and saved with stronger compression, which is still sharp for reading on screen and normal printing.

Which page size should I choose?

A4 is standard in most countries; US Letter in the US and Canada. Choose "Same as image" for digital-only PDFs where you don't want white borders.

Can I convert scanned documents?

Yes. Photos of documents or scans work well. Use A4 or Letter with a small margin so it prints like the original.

Is there a limit on the number of images?

There is no fixed limit. Dozens of photos work fine on a computer; on a phone, choose "Smaller file" for very large batches.

Are my images uploaded?

No. The PDF is created by your browser on your own device, so your documents stay private.
