# Image EXIF Editor

Write your own EXIF fields into a photo: artist, copyright, description, software and the date taken. Fields you leave empty stay as they are, and the rest of the metadata, including the color profile and XMP, is kept. It works with JPEG, PNG, WebP and AVIF files and suits photographers who want credits in every exported image or need to correct a wrong camera date.

## Frequently asked questions

### Which EXIF fields can I set?

You can set Artist, Copyright, ImageDescription and Software in the main EXIF directory, and the date taken, which is written to both DateTimeOriginal and DateTimeDigitized. Each text field takes up to 256 characters. At least one field must be filled in.

### What happens to fields I leave empty?

Empty fields are not touched. Existing EXIF values, GPS data, the ICC color profile and XMP stay in the file, and only the fields you fill in are added or replaced.

### How do I enter the date taken?

Use the form YYYY-MM-DD HH:MM or YYYY-MM-DD HH:MM:SS, for example 2024-06-15 18:30. The EXIF form with colons, such as 2024:06:15 18:30:00, also works. Impossible dates such as February 30 are rejected, and missing seconds are saved as 00.

### Can I use accents or symbols?

EXIF text fields are plain ASCII, so accented letters and symbols are written in their closest ASCII form. For example, Müller is saved as Muller and the copyright sign as (C). For full Unicode text, editing apps use XMP instead of EXIF.

### Which formats are supported?

JPEG, PNG, WebP and AVIF files up to 5 MB and 4000 pixels a side. GIF cannot store EXIF and TIFF EXIF output is not supported by the image engine, so those uploads are rejected with a message. Convert them with the Image Converter first.

### Does editing EXIF reduce image quality?

The image is written again with its metadata. PNG stays lossless, JPEG is saved at quality 92 with the original chroma subsampling, WebP at quality 92 and AVIF at quality 80. Repeated edits of the same JPEG add small amounts of compression each time, so edit from your original export when you can.

### Why add copyright and artist to my photos?

These fields travel with the file, so anyone who downloads the image can see who made it and who holds the rights. Stock sites, image search engines and many photo apps read them, and they help when you have to prove ownership.

### Can I fix a wrong camera date?

Yes. Cameras with a wrong clock or a missed time zone change record wrong capture times, which breaks sorting in photo libraries. Enter the correct date taken and the tool replaces DateTimeOriginal and DateTimeDigitized.

### How can I check the result?

Open the edited file in the Image Metadata Viewer. Your values appear in the EXIF table under Artist, Copyright, Description, Software and Taken.

### Can I delete EXIF fields with this editor?

No, the editor only adds or replaces fields. To start from a clean file, run it through the Image Metadata Remover first and then add the fields you want to keep with this editor.
