FIRST CH TOOLS / Images / 58 HEIC CONVERTER

HEIC → JPEG/PNG Converter

Turns .heic photos from an iPhone into JPEG (or PNG) that opens anywhere. Batch conversion, an optional max-edge limit and ZIP download. Photos are never uploaded — everything runs on your device.

Drag & drop HEIC photos here or click to choose files (.heic / .heif, multiple allowed)
80–90 is a practical range (higher = better quality, larger files)

How to Use

  1. Pick the outputJPEG for photographs; PNG for screenshots, artwork or anything with transparency. Set a max edge too if the images are headed for the web.
  2. Choose your HEIC filesDrag & drop the .heic files from your iPhone, or click to pick them (multiple allowed). Conversion starts once the decoder has loaded.
  3. SaveDownload them one by one, or grab everything at once with “Download all as ZIP”.

About This Tool

HEIC (HEIF) is what an iPhone saves when Camera → Formats is set to “High Efficiency”. It packs the same quality into far fewer bytes than JPEG, but Windows’ built-in viewer, most web browsers and plenty of CMS upload forms still refuse to open it. In production work this shows up every time as “the client sent photos and none of them will open”.

This tool decodes HEIC with libheif (v1.23.2) compiled to WebAssembly, then writes the pixels back out as JPEG or PNG through the browser’s canvas. Your photos are never sent to a server. Unreleased shots, client material and pictures of people can all be handled without leaving your machine.

When a HEIC holds several images — a burst, for example — the cover (primary) image is the one converted. Rotation recorded in the file (HEIF’s irot/imir) is applied during decoding, so nothing comes out sideways. Note that EXIF is not carried over: going through a canvas drops the capture date and any GPS coordinates. That is handy when you want the location gone, but keep the original HEIC if you need the date (to inspect or strip EXIF from existing JPEGs, use the EXIF Viewer & Remover).

If the images are going on a website, converting the JPEG further to WebP or AVIF will shrink it again at the same apparent quality. For pure resizing and cropping there is the Image Resizer, and for exporting every social platform size at once, Social Image Sizes.
