Real PDF redaction: drag black boxes over sensitive content and the pages are rebuilt as images, so the hidden text cannot be copied or recovered.

Compare Two PDFs

Find what changed between two PDF versions with a word-level diff and a pixel difference view, page by page. Both files stay in your browser.

Auto-Rotate PDF

Detects the text direction on every page and rotates each one the right way up, with a confidence score and a manual override per page.

Remove Blank Pages from PDF

Finds empty pages by measuring how much ink each one carries, ignores scanner speckle with a tolerance slider, and rebuilds the PDF without them.

Break a large PDF into parts that each fit under a size limit you choose. Every part is measured after saving, so it really fits.

Unlock PDF (Remove Password)

Open a password-protected PDF with the password you already have and save an unprotected copy, with no printing or copying restrictions left on it.

Check a PDF for the structural basics of accessibility: tagging, a structure tree, a document language, a real title and alt text on every figure.

Extract Attachments From PDF

Find and download every file embedded inside a PDF, including e-invoice XML payloads and file-attachment annotations, straight from your browser.

PDF to One Long Image

Turn every page of a PDF into a single PNG or JPG — stacked, side by side or in a grid — with your own gap, background colour and resolution.

PDF Image Resolution Checker

Find every image placed in a PDF and see its effective DPI at the size it is actually printed, with low-resolution pictures flagged against your limits.

Trim White Margins From PDF

Detect the content on every page and crop away the empty white border, so scanned books and reports fill an e-reader screen instead of floating in space.

Change PDF Background Colour

Give a PDF a sepia, cream or custom paper colour for easier reading, with a vector mode that keeps text selectable and a multiply mode for scans.
