About Convertify's Compress Tools
Large image and PDF files slow down websites, bounce back from email servers, and eat up storage on your phone. Convertify's compression tools shrink file sizes dramatically while keeping your photos and documents looking sharp — choose a quality level, a target file size, or compress an entire batch at once.
