Do my photos get uploaded anywhere?
No. The conversion runs entirely in your browser on your own device. Your photos are never sent to a server, we never see them, and nothing is stored. That makes this safe for private photos, site documentation, and confidential client files, unlike converters that upload your images to process them in the cloud.
What is a HEIC file, and why will nothing open it?
HEIC is the format iPhones and iPads have used for photos since iOS 11. It keeps files small at high quality, but many Windows programs, upload forms, and older tools reject it. Converting your HEIC photos to a single PDF gives you a file that opens everywhere, on any computer, with nothing extra to install.
Can I combine several HEIC photos into one PDF?
Yes. Add as many photos as you like, use the up and down arrows to set the order, and each photo becomes its own page in a single PDF, sized to match the photo so nothing is stretched or cropped.
Does this work on Windows?
Yes, and that is the main reason people need it. Windows often cannot open HEIC files without installing extra codec extensions. This tool runs in any modern browser on Windows, Mac, or Linux, decodes the photos on your own device, and never asks you to install anything.
Will my photos lose quality?
Each HEIC photo is decoded and placed into the PDF as a high quality image at its full pixel resolution. For sharing, printing, and records the result looks the same as the original in normal use. The original files on your device are never changed.
I work with heavy CAD drawings all day. What about those?
Turning photos into a PDF is the easy part. The hard part is opening and marking up a 50-200 MB+ AutoCAD, Revit or ArchiCAD export without your PDF tool freezing on scroll and zoom. That is what we built Ncored for, a fast desktop PDF editor for large construction drawings on Windows and Apple Silicon Mac. 14 days free. No signup, no email, nothing to enter.
