*** Image Converter + Metadata Editor + Photo Browser ***

PhotoMill helps you convert a bulk of images into the most popular image formats, give your files meaningful names, watermark with text and image, adjust photos (brightness/saturation/exposure/grayscale/etc.), fit geometry (scale/crop/trim/etc.), remove private metadata, add your own copyrights etc.

Also, PhotoMill is a great batch metadata editor, renamer and photo browser.

Conversion to: HEIC, BMP, GIF, JPEG, JPEG 2000, PDF, PNG, TIFF
Color models: RGB, Gray, CMYK
Color depth: 8/16/32 bits; with or without alpha channel

Correct EXIF/IPTC metadata tags in your photos: place GPS coordinates, remove private information from your photos, correct or set capture dates, add your own copyright, keywords or rating.

The app has a bunch of features for comfortable browsing and multi-criteria search of photos in the Browser.
The Browser has 3 panels: Image Info - displays detailed information about a selected photo; Groups - splits photos into groups/subgroups based on a chosen criteria, for instance, by capture dates; Search - gives you an opportunity to search photos by different criteria.

You can give meaningful names to converted photos constructing file names in the “pro” way - using text and tags: index, capture date, original name, image width, “find & replace” etc. Also, you can rename photos without any conversion.

Fit image size with a bunch of geometry actions: scale, crop, add border, trim, trim color, rotate & flip, auto rotate (by EXIF orientation), change resolution.

• Text - you can use photo metadata information - tags: capture date, keywords, camera maker etc., as well as entered text. Font size can be either fixed or relative to an image width, height, long or short edge. Multiline text, stroke, shadow, rotation, tiling and other features.
• Image - image size can be either fixed or relative to main image size. Image tiling is also available.
• Rectangle - background for text; square or rounded. Fill and stroke color can be half-transparent.

Available filters: auto contrast, auto white balance, gamma, contrast, exposure, sharpness, grayscale, sepia, colorize, temperature, HSL channels (Hue/Saturation/Lightness), HSV channels (Hue/Saturation/Value,Brightness), RGB channels, curves.
Working with transparency: alpha mask, color to alpha, alpha to color.
Color matching: assign profile, convert to profile, proof with profile.

A little practice and this works quite well

Most photo's that are taken with the iPhone are preset to "Live" and are stored as "HEIC" file formats. There are reasons for this and one could (I think) change the file presets but I've never remembered to do this.
The issues come with sharing the files to other programs such as "Final Cut Pro" in y particular case.
One can reformat files using native Mac software but this is cumbersome and done one-at-a-time. This program allows you to batch convert files to several different formats, I typically use "JGP" formats as this is the most common, and works well with Final Cut.
Program works well, you do end up with two files, so to save space you may want to delete them after conversions and usages.

Recent update broke this app!

I'm frustrated. This app worked okay until I updated to the recent version. Now it's destroying my images by adding a huge chuck of white space on top of them. It wasn't doing this before I updated. But now as soon as I press the "Convert" button, all images are made super tall because a big chunk of white space is added to them that wasn't in the original image. Not only that, but if you try to export these images, they will now export with this extra chunk of white space added on top of them, which you have to manually crop out if you wish to use your image. Also, adding borders has become useless now because the image dimensions are messed up, so the border surrounds everything, including the extra white space that this app keeps adding. These are the things that were obviously destroyed with this update, and I'm worried about what else might no longer be working properly. It's upsetting, and I wish I could downgrade to my previous version of this app, but that option unfortunately doesn't exist. Now I'm stuck with an app that's no longer functional, just because I didn't anticipate that an update would break it.

Need metadata editor ,


This application does some things fairly well, and does others so poorly, or not at all, that it is maddening to try to use. It works pretty well if you want to insert some metadata into the file. For example, I use it to insert titles, captions, and keywords. This, it does pretty well, except that when you edit the metadata, it shows you what you put in the last time you used it. You must then delete that if you want to put different info into the file currently being edited. This works well if you are editing several similar pictures and want to put the same keywords into each one. However, if you want to edit metadata that is already in the picture (remove a keyword or correct a misspelling, for example) this is simply not possible, since the app does not retrieve the existing metadata into an editable area. This is an incomprehensible oversight! I have no idea how well it does the other functions (convert, rename, rescale, etc) since I don’t use it for that. If, however, you want to actually edit metadata rather than just insert it, this probably isn’t the app for you!
