A few things you might wonder.
Are these PDF tools really free?
Yes. All 16 tools here are free to use, with no account required. To keep processing manageable, each task accepts up to 300 MB of input and PDFs of up to 500 pages in total. Images are limited to 20 per task.
Where do my files go?
They stay in your browser during processing. We do not upload your documents to a processing server. Clear the workspace or close the tab when you finish. Files you download stay on your device until you delete them.
Can I use HappyPDF on my phone?
Yes, in a modern browser. Large documents may need more memory than a phone has available. Try smaller files if your browser slows down or closes the tab.
Does it work with password-protected PDFs?
Use Unlock PDF with the appropriate password, then process the unlocked copy in other tools. Editing a digitally signed PDF can invalidate its signature.
Can I compress PDFs or convert them to Word?
Compress PDF is available with text-preserving and scanned-page modes. PDF-to-Word conversion is not included. Compression results depend on your source file.
