If you use an iPhone regularly, you've probably run into HEIC files.
On the phone, everything works perfectly.
But the moment you need to actually use those images somewhere else, things get awkward.
Maybe:
- a website only accepts PDF
- someone can't open the HEIC image
- you need to send multiple photos as a single file
- or you're trying to upload documents captured on your phone
I kept hitting this problem often enough that I decided to build a small tool around it.
That's how HEICFlow started.
Why HEIC Can Be Frustrating
HEIC is Apple's modern image format.
It has real advantages:
- better compression
- smaller files
- good image quality
From a storage perspective, it's great.
But compatibility still creates friction.
Many workflows still prefer:
- JPG
- PNG
especially when images move beyond your phone.
And in practice, most people aren't trying to "manage file formats."
They're trying to complete a task.
The Real-World HEIC Problem
Here are some situations I kept seeing.
1. Document Uploads
People use iPhones to photograph:
- passports
- receipts
- application forms
- IDs
- paperwork
Then they hit:
PDF only
Now they need a quick conversion workflow.
Not an editor.
Not a design tool.
Just something that works.
2. Sharing Multiple Photos
This is surprisingly common.
Imagine:
- travel photos
- event pictures
- screenshots
- reports
Sending 15 separate images feels messy.
A single PDF is cleaner.
Easier to email.
Easier to archive.
And often easier for the recipient.
3. Workflows and Productivity
HEIC files show up in work too.
Things like:
- meeting whiteboards
- inspection photos
- invoices
- contracts
- project documentation
Combining images into one PDF usually fits these workflows better than sharing raw files.
Building HEICFlow
I wasn't trying to build another all-in-one image suite.
There are already plenty of powerful tools.
Instead, I wanted something focused:
HEIC → PDF
Fast.
Simple.
Minimal steps.
No feature overload.
Just upload and convert.
So I built HEICFlow.
The current version focuses on a single workflow because I wanted to solve one problem well before adding complexity.
Current and Future Plans
Right now:
✅ HEIC → PDF
Planned next:
- HEIC → JPG
- HEIC → PNG
- additional lightweight HEIC utilities
The idea is to keep HEICFlow small and practical.
More workflow tool than software suite.
Try HEICFlow
If you regularly work with iPhone photos and run into HEIC compatibility issues, I'd appreciate feedback.

I'm especially curious:
What HEIC workflow frustrates you the most?
