The most-searched PDF headaches — too large, won't open, won't print, can't select text — and the free tool that fixes each one. Everything runs in your browser; files that do reach our servers are deleted within an hour.
Big PDFs are almost always full-resolution scanned images. Compressing re-encodes those images to a sensible size — often cutting the file by 70–90% with no visible change. If you have a hard limit (say 100 KB or 2 MB), compress to an exact target size instead.
Compress PDF →A PDF that won't open usually has a broken cross-reference table — often from an interrupted download or export. Repairing rebuilds the file's internal structure so viewers can read it again, without changing the content.
Repair PDF →Blank or failed prints are usually a corrupted or flattening-heavy PDF. Repairing the file fixes most cases; if a specific page is the problem, re-saving the document through a tool normalises it. Password-protected PDFs can also block printing — unlock it first.
Repair PDF →That means your PDF is a scan — a picture of text with no text layer. Running OCR recognises the words and adds an invisible, selectable text layer, so you can search, copy and (later) split by text.
OCR PDF →If you know the password but the file blocks editing, printing or copying, removing the permissions password unlocks those actions. Everything runs in your browser — the password is never uploaded.
Unlock PDF →Before fixing anything, it helps to see the facts: page count, page size, PDF version and document metadata (title, author, producer). PDF Info reads all of that right in your browser — nothing is uploaded.
