PDF Tools Directory
Everything you need to work with PDFs — mostly right in your browser.
New here? Start with Merge PDF.
It's the most common first stop — combine a few files into one PDF in seconds. You can always come back and explore the rest.
Merge PDF
Combine two or more PDFs into a single document, instantly in your browser. Your files stay on your device.
Split PDF
Pull out the pages you need or break a large PDF into separate files — all in your browser.
Compress PDF
Shrink your PDFs for email or upload with two quality presets, instantly in your browser.
Organize Pages
Drag pages to reorder, rotate, delete, duplicate, insert blank pages and add pages from another PDF, with undo and redo, right in your browser.
Crop PDF
Trim margins off one page or every page with a draggable crop rectangle or exact margin inputs, in inches or millimeters, right in your browser.
PDF to DOCX
Turn a PDF back into an editable Word file. AI reads the structure and rebuilds headings, paragraphs, lists and tables.
Image to PDF
Combine images into a single PDF, or extract every page of a PDF as PNG images.
Add Text
Drop a text box anywhere, type, resize, change color and font size, then flatten it into the page.
Fill PDF Form
Type into the PDF's own fillable fields, check boxes and pick options — all in your browser, then download a filled copy.
Add Page Numbers
Add page numbers in your preferred position and format, with a starting number of your choice.
Watermark PDF
Stamp a repeating label like DRAFT or CONFIDENTIAL across every page, with adjustable position, opacity and size.
OCR / Make Searchable
On-device OCR reads your scanned pages and adds a hidden, searchable text layer — your file never leaves your device.
Quick Sign
Draw, type, or upload a signature and initials, place them anywhere, then flatten into one downloadable PDF.
Password Protect
Encrypt a PDF with a password entirely in your browser — your file and password never leave your device.
Remove Password
Strip the password from a PDF you own or are authorized to modify, producing an unlocked copy — all in your browser.
Chat with PDF
Load a text-based PDF and ask any question — answers are grounded in your document's content.
Annotate PDF
Highlight text, draw freehand, add shapes, sticky notes and text boxes. Annotations are saved as standard PDF markup you can edit in Acrobat, Preview and browsers.
Redact PDF
Draw boxes over what to hide, or auto-find text and common patterns. Redacted pages become images so the original content is truly gone — verified before download.
Compare PDFs
See exactly what changed between two versions of a document. Added, removed and changed words are highlighted side by side, with a changes list and a PDF report — all in your browser.
PDF Metadata
Inspect everything your PDF reveals, then edit the document info or strip metadata, attachments and JavaScript, right in your browser.
Free Invoice Generator
Create a professional invoice or quote and download it as a PDF. Free, no sign-up, nothing leaves your browser.
InvoicingNew
