Why make a copy of a HEIC photo?

HEIC packs a photo like a lunchbox: the receiving app needs to know how to open it. FluffyBench's HEIC converter reads the picture and saves a separate JPG, PNG or WebP.

A HEIC photo is read into a separate image file, with the original beside the new copy.

What changes when HEIC becomes JPG?

JPG rounds off some picture detail when it saves, a little like a photocopy softening tiny edges. Quality changes how much detail it keeps.

For one locally prepared HEIC photo, the default JPG came out about half the size; Quality 100 made a larger file than the HEIC. Formats and quality settings pack pictures differently, so a JPG is not automatically smaller.

The whole ship-wake photo marks one region, followed by matched HEIC and two JPG crops with their complete file sizes.

Need a smaller JPG or different pixel dimensions?

Percentage shrinks both sides together. Dimensions can fit the same photo inside a smaller box without stretching it when Keep aspect ratio is checked.

The original photo outline contains a smaller copy with unchanged proportions; a width-and-height box contains the whole wide photo with space above and below.

Need to fit a strict upload cap? FluffyBench's Image Space Saver helps you compare size and quality choices for that job.

What should you check before sharing a converted photo?

Open the saved copy in its destination. FluffyBench's Image Viewer is shown here as an example: the photo opens as JPG, you can read the file information and inspect the picture.

The saved ship-wake JPG opens as a photo in Image Viewer.

Check the picture

Image Viewer identifies the saved file as JPEG and shows its dimensions and size.

Check the format, dimensions and size

  1. Format

    Check that your destination accepts the saved format: JPEG here.

  2. Size

    Compare the finished file size with your upload cap.

  3. Look

    Inspect the picture detail that matters for your use.

What does FluffyBench preserve from HEIC?

A converted photo carries the main picture, with rotation and mirroring applied. Some things stored beside the HEIC picture don't travel into the copy.

Rotation and mirroring are applied; the separate alpha image, HDR brightness, EXIF and GPS are not retained. WebCodecs converts Display P3 to sRGB.
The browser's image decoder handles color itself when it reads the photo; embedded ICC profiles aren't copied into the output.

Extra pictures and sequences don't always travel into the copy; read any notice on the completed row. For moving pictures, see GIF, WebP and APNG compared.

Why did a HEIC conversion stop?

FluffyBench needs your browser to read HEIC. If it can't, the workspace shows a message like this Windows example, with a suggestion for that device.

This browser can't convert HEIC photos. Open this page in Chrome or Edge to convert them here.

Windows browser notice

Follow the suggestion displayed on your device.

A message naming bit depth or color sampling means the file uses a HEIC variant FluffyBench can't read. It reads 8-bit, 4:2:0 images; 10-bit, 4:4:4 and 4:2:2 inputs are refused.
