Adobe Acrobat (https://www.adobe.com/acrobat) is a popular tool, but it has significant limitations. The main difference with FreeConversion is privacy: unlike Adobe Acrobat which sends your files to remote servers, FreeConversion processes everything locally in your browser using WebAssembly technology.
This means your sensitive documents (contracts, resumes, bank statements) never leave your computer. Additionally, FreeConversion is 100% free with no file limits, no registration, and no ads.
Yes, compressed PDFs remain in standard PDF format and open in all PDF readers (Adobe Reader, browsers, mobile apps, etc.).
Yes, our PDF compressor is completely free. No hidden fees, no registration required, and no file size limits.
Currently, you can compress one file at a time. However, the process is very fast and you can compress as many files as you want consecutively.
Low compression (10-30% reduction) preserves maximum quality. Medium (30-50%) offers a good balance. High (50-70%) significantly reduces size with slight image quality loss. Maximum (70-90%) creates the smallest possible file.
