HEIC Converter

Convert HEIC photos (from iPhone / iOS) to PNG or JPEG. All processing happens in your browser.

Drop a HEIC file or click to select

Supported formats: .heic,.heif,image/heic,image/heif · Max size: 50MB

How to use

  1. Drag & drop your HEIC/HEIF file

  2. Choose the output format (PNG / JPEG)

  3. Download the converted image

You move photos off an iPhone and find files ending in .HEIC that will not open, will not preview on Windows, and get rejected by upload forms. Nothing is broken — iOS simply saves in HEIC by default.

HEIC stores the same quality in a smaller file than JPEG, but support for it is still patchy. OFFiler converts HEIC to JPEG or PNG inside your browser, with no photo ever leaving your device. Below: why conversion is needed at all, how to choose the quality, and what to chain afterwards.

Why conversion is necessary

Browser support is split

Safari displays HEIC natively; Chrome and Firefox do not. That gap is why the same photo opens fine on an iPhone or a Mac and refuses to open in Chrome on Windows — and, ultimately, why upload forms still ask for JPEG.

This tool decodes HEIC into pixels inside the browser and writes the result out as JPEG or PNG. The decoder is loaded only when you actually need it, so it costs nothing when you are using the other tools.

JPEG or PNG, and at what quality

You can output JPEG or PNG. For photographs, JPEG is normally the right answer. Quality presets are high (92), balanced (75), and small (55), and a direct value can be entered; the default is 92, chosen so that converting out of HEIC does not visibly cost you quality.

PNG is lossless, so nothing degrades, but for photographs the file will be considerably larger than JPEG. Choose it when the image is an intermediate you will edit further, or when transparency is involved.

Things to watch for

The output is usually larger than the input

HEIC compresses efficiently, so expressing the same quality as JPEG normally produces a bigger file. "It got larger after converting" is not a failure, it is the nature of the formats. If size matters, drop the quality preset or chain compression or resizing afterwards.

Decoding leans on your device

HEIC decoding is computationally heavy, and high-resolution photos can take a moment. You may wait longer than you would on a server-side converter — in exchange, the photo never leaves your device, which matters most for exactly the photos you would hesitate to upload.

Files with .heic and .heif extensions are accepted. If your iPhone is set to "Most Compatible", photos are already saved as JPEG and you do not need this tool at all.

What to chain afterwards

Building a submittable PDF

To submit documents or receipts photographed on an iPhone as a PDF: the image-to-PDF tool accepts only PNG and JPEG, so HEIC cannot go in directly. Convert to JPEG here first — and slot in the EXIF remover on the way if the location should not travel with them.

Frequently asked questions

What is HEIC?
A high-efficiency image format used by iPhones. Some Windows apps and websites can't open it, so converting to PNG/JPEG helps.
