Handling images one at a time costs a lot of hours when you are preparing a whole gallery or catalog. This bulk image compressor takes the entire batch at once: drop in the files, set the options a single time, download an archive.
The report that comes with it lists the size before and after for each image, plus the total savings. That is useful for justifying an optimization pass to a client, or just for checking that the settings you chose deliver what they promise.
Resizing happens as the file is read: the pixels you do not need are never decoded, which noticeably speeds up a batch of camera photos.
When is this tool useful?
- Slim down visuals before putting them online
- Standardize the format of a batch of photos
- Prepare images to send by email
- Fit an image to the constraints of a site or a platform
