Guides › How to convert HEIC to JPG and turn images into a PDF
Fix iPhone HEIC photos that won’t open, and combine images into a single PDF — free and private.
Open Pyntra — it's free →Two everyday conversion headaches: iPhone photos saved as HEIC that will not open on a Windows PC or in some apps, and needing to combine several photos into a single PDF for a form or upload. Both are easy to fix once you know what is going on. This guide explains the HEIC format and shows how to convert images to JPG or into a PDF, privately and for free.
By default, modern iPhones save photos in HEIC, a format that stores high quality in a smaller file than JPG. The catch is that HEIC is not universally supported: send one to a Windows PC or upload it to an older web form and it may refuse to open. Converting the file to JPG solves this instantly, because JPG opens everywhere.
Converting is simply re-saving the image in the JPG format. The visible quality stays effectively the same for normal use; you just get a file that every device and app understands. If you regularly send photos to non-Apple devices, converting to JPG before sharing avoids the "I can’t open this" reply.
Forms, applications and portals often ask for a single PDF rather than a pile of separate images. Combining photos into one PDF puts each image on its own page in the order you choose, producing one tidy file that is easy to upload and to read. It is the standard way to submit scanned documents, receipts or ID photos.
Personal photos and documents are exactly the kind of thing you should be careful about uploading to random conversion sites. Pyntra converts HEIC to JPG and turns images into a PDF entirely in your browser, so your files never leave your device and there is no account to create.
