How it works
One PDF, many photos
Modime decodes each HEIC, rotates it correctly, and lays your photos out in a single PDF. Choose your paper size (A4, US Letter, Legal), orientation, and how many photos fit on each page. Pages are in drop order.
Sensible compression
Photos are embedded as JPEG inside the PDF. You control the quality with the slider — 85% is a good balance of clarity and file size.
Questions
Is my data private?
Yes. Everything happens in your browser. Open your Network tab while converting — you’ll see zero traffic during processing.
Can I combine multiple HEIC files into one PDF?
Yes. Drop as many as you like. They’ll be combined into a single PDF in drop order.
What’s the practical upper limit?
Around 50 high-resolution iPhone photos on a modern computer. More is possible but may be slow; try splitting into batches if you hit the wall.
Can I use this offline?
After the page has loaded once, yes. Disconnect your internet and try it.
Why not just use my computer's built-in viewer?
You can — Preview on macOS or Photos on Windows handle a handful of files fine. Modime is faster for large batches, runs on any OS, and doesn’t require you to open a separate app first.
I just want single JPGs, not a PDF.
Use HEIC to JPG instead.
