Convert HEIC, WEBP and AVIF to JPG

Features

• Nothing is uploaded, ever. Search for "convert HEIC" and almost every result is a website, which means your photographs travel to a stranger's server and stay there under a policy you never read. This app contains no networking code at all.
• It tells you the truth about size. Converting to JPEG usually makes files larger, because JPEG is thirty years older than the format you are leaving behind. The numbers shown here are the real ones, and they go up when they go up.

Drop, pick, convert

1. 01

   Drop the files in

   Or a whole folder, or open them from the panel. HEIC, WEBP, AVIF, PNG, JPEG, TIFF, and whatever else your Mac can read: the app asks the system at launch instead of promising a fixed list.

2. 02

   See what you actually have

   Every row shows the dimensions, the format read from inside the file rather than off its name, the camera that took it, and a pin if the photo carries a location.

3. 03

   Choose the format and the destination

   JPEG, PNG or HEIC, at a quality you set, saved beside the originals or into a folder you pick. One switch decides whether the camera metadata travels, and the pins in the list update to match.

4. 04

   Convert, then check the numbers

   Every row shows the size before and after. Nothing is estimated, and nothing is rounded into a claim about savings.

The parts other converters leave out

After the run

What it cost, in real numbers

Six files converted and one skipped, each with its size before and after. Most of the numbers go up, because that is what converting to JPEG does, and an app that hid it would be lying about the trade. What you get in return is a file that opens everywhere.

Set once

Defaults, and a promise about your originals

The format, quality and metadata setting you want every time, plus how the copies are named. Underneath sits the sentence the whole app is built around: originals are never changed or overwritten. A conversion only ever adds a file.

What you get

• The three formats people get stuck on. HEIC from an iPhone, WEBP from a web page, AVIF from a newer one. These three are why anyone goes looking for a converter, and each is identified by reading the file itself, never by guessing from the extension.
• No limit on a batch. Seven files or seven hundred, as often as you like. There is no cap, no daily allowance, and no paid tier waiting to raise one, because there is no paid tier.
• Your originals are never touched. Every conversion writes a new file. Nothing is modified in place, nothing is overwritten, and there is deliberately no option anywhere in the app to delete what you started with.
• The location travels only if you say so. A photograph records where it was taken. Rows with coordinates show a pin, the pin is struck through when the copies will be written without them, and the switch that decides is one click away in the title bar.
• A quality dial, not a size preset. Finder's built-in Convert Image offers Small, Medium and Large. This app offers the number that actually decides the trade-off, applied consistently to every file in the batch.
• Copies where you want them. Beside the originals, which is usually what you want, or in a folder you choose once. The title bar always states which of the two is about to happen.
• When it cannot convert, it says why. A file that is not an image is skipped, with the reason on its own row. A damaged file is flagged as possibly damaged instead of failing the whole batch. Nothing stops halfway with a dialog you have to dismiss.
• No account, no analytics, no network. Nothing to sign in to and nothing being counted. The app makes no network requests of any kind, which makes for the shortest possible privacy policy.

Why the copies come out bigger

People convert images expecting to save space, and this is the one case where converting costs space instead. That deserves a plain explanation rather than a footnote.

JPEG was standardised in 1992 and has not changed since. HEIC and AVIF are still images built from modern video codecs, and they store the same photograph, at the same visual quality, in roughly half the bytes. Converting to JPEG runs that in reverse: a 289 KB HEIC becomes a 376 KB JPEG, and a 110 KB AVIF becomes a 177 KB JPEG. Those figures are measured, at a quality where the loss is invisible.

So this is a compatibility tool, not a compression tool. The extra bytes buy a file that every piece of software on earth can open, which is worth a great deal on the day something refuses to open the one you have. If space is what you are short of, the useful dial is quality, and the useful direction is the other way: converting JPEG to HEIC roughly halves the size.
