Does the job without fuss

By Tyler Tork (TylerTork) on September 19, 2025

This is invaluable when working with non tech-savvy users who don't know how to reduce the sizes of images before uploading, and a big convenience for other users. I could wish the instructions were a little clearer, and the default values for a lot of the settings results in a very poor-quality image, so I would've chosen different, less strict limits for file size and quality settings. It's also not being updated to reflect the fact that it works with recent WordPress versions -- but it does, so far.

So: not a perfect plugin, but the only one I can find that does exactly what I need for image uploading on CF7.

Works wel, required field has errors

It is impossible to require customers upload pictures. If I require an upload, the pictures won't send to my mail address. This is a long-known issue, but creator wont patch this problem.

Excellent works well on mobile devices

Great plugin. I didn't need the compressing function but was more looking for multi-uploader that worked on mobile devices. After my Contact Form 7 form is submitted I have some code which puts the information into Woocommerce. All the other uploaders seem to have a problem if the images are created from a camera. This plugin doesn't and it works very well. Would be nice to have additional options for mobile cameras. Currently when I click browse files I have the option of using the camera or selecting existing images. A default options straight to camera would be great. Also the ability to take multiple photos without having to keep going back and clicking browse files would be even better. Similar to how ebay does it when adding a listing.

Really useful

Well Done!

Excellent little plug-in, thank you! The only issue I had was that by making the uploading of a photo *required, it didn't work. By removing the *requirement, it works like a charm!! 5 stars from me 🙂

Perfect!!!!!!
