Stop fighting HEIC files.
Ever AirDropped a photo from your iPhone to your Mac, or saved one from the Photos app, and ended up with a HEIC file that a website, form or tool won’t accept? Dropfix watches any folder you choose and when a new HEIC file arrives, it’s converted to the format and size that you decide.
Free to download, with 100 conversions a month included. Dropfix Pro is a one-time unlock of A$6.99 for more folders and rules with no monthly limit. Requires macOS 15.6 or later. Everything happens on your Mac: Dropfix has no account, no analytics and never sends your photos anywhere.

- Drop a file inDropfix waits for it to finish arriving, then converts it. The result is written next to the original, never over it.
- Confirm, or don’tA step-by-step panel shows each conversion. Or switch to automatic conversion with a brief notificationPRO and let it run on its own.
A look inside
Small, and out of the way
Everything lives in a menu bar panel. These are the real screens.
Use cases
Where it earns its keep
Anywhere iPhone photos meet a system that wants JPEG.
AirDrop from your iPhone
AirDrop lands in Downloads as HEIC. Put a rule on Downloads and every photo you send yourself is a JPEG by the time you look for it.
Uploading to websites and forms
Listing photos for a rental or marketplace, a job application, a CMS, a client portal: many only take JPEG or PNG. Convert first and the upload just works.
A drop folder for the right format
Make a folder called “To JPEG” and give it a rule. Drag any image in and it comes out in your preferred format and size.
Smaller files for email and messaging
The Small size shrinks photos to 1280 px on the longest side, so a batch of holiday photos fits in one email.
Screenshots and web images
PNG screenshots to JPEG for sharing, WebP downloads to PNG for editing. Dropfix handles PNG, JPEG, TIFF and WebP as well as HEIC.
Photos exported from the Photos app
Exporting originals from Photos on the Mac gives you HEIC. Export into a watched folder and the JPEGs appear beside them.
Formats and sizes
Your format, your size
Each rule pairs one input format with one output and a quality. PRO marks what Dropfix Pro adds; the free version watches one folder with one rule and includes 100 conversions a month.
Formats
Any of these arriving in a watched folder…
…becomes the output you chose, JPEG or PNG.
Sizes
The same four as Finder’s Convert Image.
Actual Size: original dimensions, for archiving or printing.
Large: 4096 px on the longest side. Full detail on a 4K screen, enough for an A4 print.
Medium: 2048 px, sharp on most screens, good for email and sharing.
Small: 1280 px, the smallest files, for messaging and the web.
JPEG is saved at 80% quality, PNG stays lossless, and nothing is ever enlarged.
Metadata kept
EXIF, GPS location, colour profile and rotation carry across to the converted file.
Originals are safe
Converted files never overwrite anything. Optionally the originals move to the Bin, where they can be recovered until you empty it. Doing that automatically, without confirming each time, is part of Dropfix Pro.PRO
Rules never chain
Files Dropfix makes don’t trigger another rule, so HEIC to PNG and PNG to JPEG can share a folder without looping.
Convert what’s already therePRO
Point Dropfix at a folder full of HEIC files and press the rule’s run-now button. It always confirms before any originals move.
Privacy
Everything stays on your Mac
An app that watches your folders has to earn trust, so here is exactly what Dropfix does.
No account, no analytics
Dropfix has no sign-in, no usage tracking and no crash reporting. There is nothing to opt out of.
Your photos never leave your Mac
Conversion uses macOS’s own image libraries. The only time Dropfix talks to anything is to confirm a Dropfix Pro purchase with the App Store.
Only the folders you choose
Dropfix sees only the folders you pick in its folder chooser, and only acts on files that match a rule you set.
In plain English

Questions
Frequently asked
More in the full FAQ.
What is a HEIC file, and why can’t I upload it?
HEIC is the format iPhones and iPads use for photos. It makes smaller files than JPEG at the same quality, but many websites, forms, CMSs and older tools only accept JPEG or PNG, so a HEIC upload is refused or shows as a blank image. Dropfix turns HEIC files into JPEG or PNG the moment they arrive on your Mac.
How does Dropfix work?
You choose folders to watch, such as Downloads or Desktop, and add a rule to each, like “HEIC to JPEG, Actual Size”. When a file matching a rule lands in that folder, Dropfix waits for it to finish arriving, then converts it. The converted file is written next to the original. Files Dropfix makes never trigger another rule, so rules can’t loop.
Does it convert automatically or ask me first? PRO
Your choice. By default a small panel opens from the menu bar icon showing the stages, Reading, Converting, Originals and Done, so you can confirm the output and decide what happens to the originals. With Dropfix Pro you can choose Convert automatically with a brief notification instead: the menu bar icon flashes a few times and a small alert appears below it with the details.
What happens to the original photos?
Nothing, unless you ask. Converted files never overwrite anything. You can have the originals moved to the Bin, which is Finder’s own Move to Bin, so they can be recovered until you empty it. The first time, Dropfix shows how to get them back. Doing that automatically, without confirming each time, is part of Dropfix Pro.
Which formats does it handle?
In: HEIC, PNG, JPEG, TIFF and WebP. Out: JPEG or PNG. Each rule picks one input format and one output.
Can I control the size and quality?
Yes. Each rule has a size, the same four as Finder’s Convert Image: Actual Size (original dimensions), Large (4096 px on the longest side), Medium (2048 px) or Small (1280 px). JPEGs are saved at 80% quality; PNG is lossless. Nothing is ever enlarged.
