LocalDocu vs Smallpdf questions
Is there a free Smallpdf alternative without limits?
LocalDocu is free with no task limits or sign-up, because processing runs on your device instead of paid servers. It covers merging, splitting, page editing, compression and Word-to-PDF.
Does Smallpdf upload my files?
Yes. Smallpdf processes files on its servers. Its privacy notice states that files processed with most tools are deleted after one hour, while files you store in an account are kept until you delete them.
Can LocalDocu replace Smallpdf entirely?
For organising and compressing PDFs, often yes. For e-signing, OCR or editing text in a PDF, you will still need a tool like Smallpdf or Acrobat.
