Convert, unlock, compress, merge, split and manage PDFs — all from your browser. Every tool on this hub runs 100% client-side using pdf-lib and pdfjs-dist, so your files never leave your device. No account, no watermarks, no usage limits.
Extract readable PDF text into a real editable .docx document. Original layout, tables and images are not preserved; scanned pages need OCR, which is not included.
Convert text from .docx or .txt into a PDF with wrapped lines and page breaks. Original formatting, images and tables are not preserved. Legacy .doc files are not supported.
Stitch several PDFs into one file — cover letter + CV, or scanned pages that arrived one at a time.
Pull out the pages you actually need from a long PDF — one chapter, a single invoice, or every page as its own file.
Optimize PDF structure without rasterizing, or choose stronger JPEG page compression for scans. JPEG mode removes searchable text, links, forms and signatures. If the result is larger, the original file is returned.
Turn each PDF page into an image you can drop into a slide, a social post, or a website — without screenshotting page by page.
Turn a stack of phone photos or scans into one PDF — the format receipts, forms and portals actually accept.
Fix a PDF that opens sideways or upside-down — usually a scanner that grabbed the page the wrong way round.
Remove PDF encryption locally using the correct password with modification permissions. This tool does not recover forgotten passwords.
Encrypt your PDF locally with AES-256 and a password required to open it. Keep your password safe. Unlock already encrypted documents before adding a new password.
