The Complete Guide to Free Online PDF Tools

PDFs are the universal format for documents, but editing them usually means expensive software or sketchy upload sites. Quill Tools processes PDFs entirely in your browser — your files never leave your device, so contracts, invoices, and personal documents stay private. This guide covers each free PDF tool and exactly when to reach for it.

01

Merge PDF Files

Combine multiple PDFs into a single document — perfect for assembling reports, stitching a resume and cover letter together, or packaging scanned pages. Drag files into order and download one merged PDF. Because everything runs locally, even confidential documents never get uploaded to a server.

02

Split & Extract Pages

Break a large PDF into separate files or pull out just the pages you need. Ideal for extracting a single chapter, removing confidential pages before sharing, or splitting a scanned batch into individual documents. Select page ranges and export instantly.

03

Convert Images to PDF

Turn JPGs and PNGs — like photos of receipts, whiteboards, or handwritten notes — into a single, tidy PDF. Reorder images, then export a portable document that's easy to email or print. Great for students digitizing notes and businesses filing receipts.

04

Rotate PDF Pages

Fix sideways or upside-down scans by rotating individual pages or the whole document 90, 180, or 270 degrees. Save the corrected orientation permanently so the PDF displays and prints the right way up everywhere.

05

Compress a PDF without wrecking the text

Most compressors take one silent shortcut: they flatten every page to an image. The file shrinks impressively and the text stops being text — no longer searchable, selectable, or readable by a screen reader, and you find out weeks later. Compress PDF offers both approaches explicitly. Lossless rewrites the file structure and leaves text untouched, with modest savings. Rasterise produces dramatic reductions and is the right choice for scans, which are already images. The tool detects whether a text layer exists and only warns when there is something to lose — and when savings come in under five per cent it says the file is already optimal rather than handing you a two per cent win.

06

Reorganise, number and watermark

Delete and reorder pages in a single pass, with thumbnails badged by their position in the finished document and deletions reversible until you save. Add page numbers with custom formats and a skippable cover page, or stamp every page with a watermark at adjustable opacity and angle. All three place content correctly on pages carrying a rotation flag — PDF editors draw in the unrotated coordinate system, so a number placed at bottom centre on a sideways scan lands against a side edge in most tools.

07

Passwords and text extraction

Unlock PDF removes encryption from a document you can already open — it decrypts, it does not crack. Protect PDF adds AES-256 with per-action printing, editing and copying controls. Both run qpdf as WebAssembly in the page, so neither the document nor the password is ever transmitted, which is a genuine difference from every well-known alternative. Extract Text pulls out the text layer and states plainly when a PDF is a scan with nothing to extract, rather than returning an empty box.
