I had a client site where the developers used ALL PNG IMAGES and it was SLOW. Thank you for this awesome plugin you saved me a ton of time not having to convert manually & re-upload via GIMP!

Easy to use and efficient. The bulk convert page loads fast, the images were generated and replaced neatly. I saved over 80MB converting approximately 350 PNGs, and this was only a test run. Lovely plugin!

The plugin converts the format and replaces the address in the database well and without any problems. Be sure to back up before use to avoid problems

Плагин нашел лишь малую часть моих PNG. Затем заменил полноразмерные png на jpg при этом они все исчезли из тех записей где стояли. Также (!) уменьшенные варианты этих же изображений ОН ОСТАВИЛ В ТОМ ЖЕ ФОРМАТЕ PNG. Таким образом были убиты самые большие PNG и больше ничего не изменилось. Я это делал птому что у меня есть backup сайта 🙂
