If you've ever tried sending an iPhone photo to a friend on Windows or uploading it to a service that doesn't support HEIC, you've hit the wall: HEIC is everywhere on iPhones but supported almost nowhere else.

Apple uses HEIC (High Efficiency Image Container) because it produces files about half the size of JPG for similar quality. The trade-off is compatibility — Windows 10/11 needs an extension, most websites reject the format, and tools like Slack and Discord refuse the upload.

This guide shows the fastest way to convert HEIC to JPG without uploading anything anywhere.

Quick answer

Open Convertify's image tool, drop your HEIC, pick JPG, download. Takes about two seconds.

Everything runs in your browser. No upload. No account. No watermarks.

Step-by-step

1. Open the image converter

Go to getconvertify.me/image.

2. Drop your .heic file

Drag from your desktop, photo library, or click the dropzone to pick. You can also drop multiple files anywhere on the page.

3. Pick JPG as the output format

Use the format dropdown. JPG is selected by default if your input was HEIC.

4. Adjust quality (optional)

Move the Quality slider between 10–100%. For most uses, 90% looks identical to the original at ~40% smaller. Drop to 70% for chat/social where the difference is invisible.

5. Download

Click Download. The JPG saves to your default downloads folder.

Why your files never leave your browser

Convertify uses WebAssembly — the same image library (ImageMagick) that powers Photoshop scripts and Wikipedia thumbnails, compiled to run in your browser tab.

When you drop a file:

Browser reads it into memory
WASM converts it to JPG locally
Result downloads to your computer

There's no server step. We never see your photo. Even if we wanted to, we couldn't — the file isn't on our infrastructure.

This matters for:

Personal photos you'd rather not upload to a random "free converter" site
Sensitive documents (HEIC supports embedded metadata)
Slow connections where uploading then downloading wastes bandwidth

Other HEIC-to-anything conversions

Convertify supports HEIC to:

Target	When to use
JPG	Universal compatibility, smaller file
PNG	Transparency, lossless
WebP	Smaller than JPG at same quality, modern browsers
AVIF	Smallest, but limited support outside Chrome/Firefox

All free, all in-browser.

Bulk convert HEIC photos

If you have a folder of HEICs (iPhone backups, AirDropped batches), use the batch tool instead. Drop the whole folder, pick JPG, get a ZIP back. Limit is 100 free conversions per day — go Pro for unlimited.

FAQ

Does Convertify keep my photos? No. Conversions run in your browser. We never receive the file.

Why does HEIC exist at all? Apple introduced it in iOS 11 (2017) to halve photo storage. Apple devices read it natively; everyone else has to convert.

Is the JPG quality the same? HEIC stores more color information than JPG, so JPG is technically a downgrade. At 90% quality the visible difference is essentially zero. At 100% it's pixel-near-identical for most photos.

Can I convert HEIC to PDF? Yes — convert to JPG first, then drop the JPG into the Markdown to PDF tool inside an image link, or use a PDF creator. We may add direct HEIC→PDF later.

What about HEIF? HEIF is the same format as HEIC (HEIC is just Apple's branding). Convertify treats both identically.
