*** 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: 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.

Excellent. - Has performed exactly as described. Just a thought for the creators to make the Crop tool more freehand. Awesome App.

Review by IslandMom53

Would love to use this but…... - I’ve spent the day trying to use this app. I never get very far and it crashes, and crashes, and crashes. So frustrating to use. I think it might do what I am looking for, but the darn program won’t stay open long enough to complete anything. Additionally I don’t see where there it a help or tutorial built in. Total waste of my time and money.

Review by Need metadata editor

Maddening - 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!

Version 1.3.4
Review by gnostic student

Solid app. Very responsive customer support. - Includes a very clever feature for renaming files that allows you to combine preset functions that you choose with your mouse together with characters that you type on the keyboard to create your own presets. The coolest part about that is how easy it is to use. It has all the filters that I need for batch editing. And when I wrote to the developer to ask a question, he replied within the hour with a very simple solution. Very helpful.

Review by Rick-G.

Great for editing “product" shots - Was looking for a quick and simple way to batch edit (white balance and exposure) product shots for our ecommerce business. This little app fits the bill perfectly. It’s the simplest thing I’ve seen yet to do an effective batch edit. Results are excellent too. Highly recommended. Thank you for a very useful photo app!

Review by ehny32

Does exactly what it claims - This is an excellent piece of software. It has some powerful features and does what it is supposed to do. It is stable too. The UI could maybe be a little more intuitive, but I worked it out. I had a question about how to do something and support got back to me very quickly with clear instructions. Great support!
