We must have an Aadhaar card PDF or similar identity documents on our phones for everyday government tasks. A lawyer must split pages of confidential court documents. A teacher may need to compress 50 students’ report PDFs in a single batch. A hospital employee needs to combine patient records.
Furthermore, a freelancer combines invoices and bills to send to a client. Moreover, they may prefer to keep their PDFs only on their devices, so no one else can see them, with no uploading, external transfer, or cloud storage at all.
Do you believe me when I say that your PDFs can be split, merged or compressed for 100% free with no file or size limits, without signing up, fully offline, and without sending them across the internet to a remote server like ILovePDF, Adobe Acrobat, etc.?

CATEGORY 1 — Edit & Annotate (20 Tools)
These tools help you modify, mark up, and improve your PDF.
1. PDF Editor
What it does: Open and edit your PDF directly. You can highlight text, add comments, draw shapes, insert images, and redact (hide) content.
Example: You received a contract PDF. You highlight the important clauses in yellow, add a comment saying “Need to review”, and sign it — all without printing.
2. Edit Bookmarks
What it does: Add, edit, or delete bookmarks inside a PDF. Bookmarks are like a table of contents that lets readers jump to specific pages quickly.
Example: You have a 200-page research PDF. You add bookmarks for Chapter 1, Chapter 2, and the appendix so readers can jump directly to any section.
3. Table of Contents
What it does: Automatically generate a Table of Contents page from the bookmarks already in your PDF.
Example: Your eBook has 10 chapters with bookmarks. This tool creates a clickable table of contents page at the beginning automatically.
4. Page Numbers
What it does: Add page numbers to the bottom or top of every page in your PDF.
Example: You have a 50-page report PDF with no page numbers. You add numbers at the bottom centre of every page before submitting it.
5. Add Page Labels
What it does: It applies custom labels to pages – like Roman numerals (i, ii, iii) for the intro pages, like the introduction, or custom prefixes, like “Appendix-A”.
Example: Your book PDF has a preface (pages i to v) and then main content (pages 1 to 100). You label them separately to match the printed book style.
6. Bates Numbering
What it does: Add a sequential identification number (called a Bates number) to every page across one or more PDF files. Used in legal and business documents.
Example: A lawyer has 5 different case documents. She adds Bates numbers (001, 002, 003…) across all files so every page has a unique ID for court reference.
7. Add Watermark
What it does: Stamp text (like “CONFIDENTIAL” or your website name) or an image logo over every page of your PDF.
Example: You create a digital product (eBook) and add your website name “PayalPedia.com” as a light watermark on every page before distributing it.
8. Header & Footer
What it does: Add any text to the top (header) or bottom (footer) of every page — like your company name, date, or document title.
Example: You add “Annual Report 2025 — ABC Company” in the header and “www.abccompany.com” in the footer of a 30-page business report.
9. Invert Colors
What it does: Flip the colours of your PDF – white becomes black, and black becomes white. This creates a dark mode version of your PDF.
Example: You have a white-background PDF that strains your eyes at night. You invert the colours to get a dark background with white text for comfortable night reading.
10. Scanner Effect
What it does: Makes your digital PDF look like it was physically scanned — adds a slightly aged, scanned paper appearance.
Example: You need to submit a digital document, but it must look like a scanned hard copy. This tool adds that authentic scanned look without any printing or scanning.
11. Adjust Colors
What it does: Change the brightness, contrast, and saturation of your PDF pages — like editing a photo.

15. Add Stamps
What it does: Add image stamps (like an official seal or logo) to your PDF pages using the annotation toolbar.
Example: A company adds its official red stamp image to every page of an outgoing contract PDF before sending it to a client.
16. Remove Annotations
What it does: Delete all comments, highlights, underlines, and links that were added to a PDF.
Example: You received a PDF with many reviewer comments and highlights. You use this tool to clean it up and produce a fresh, clean version for final printing.
17. Crop PDF

Example: A scanned document has large white margins. You crop all pages to remove the extra space and make the content fill the page properly.
18. PDF Form Filler

Example: You download a government application form as a PDF. You fill in your name, address, and other details directly online and download the completed form.
19. Create PDF Form
What it does: Build your own fillable PDF form from scratch using drag-and-drop text fields, checkboxes, and dropdowns.

Example: A government archive requires all submitted documents to be in PDF/A format. Convert your regular PDF to PDF/A before submission.
98. Fix Page Size
What it does: Standardises all pages in your PDF to a uniform size — like making all pages A4 even if some are A3 or letter size.
Example: Your PDF has pages of different sizes because you combined documents from different sources. Fix Page Size to make all pages the same A4 size.
99. Linearize PDF
What it does: Optimise the PDF file structure so it loads faster when opened in a web browser (also called “Fast Web View”).
Example: You have a large PDF on your website that takes too long to open online. Linearise it so the first pages appear immediately while the rest continue to load.

107. Sanitize PDF
What it does: Clean your PDF by removing hidden metadata, annotations, scripts, embedded files, and other hidden content that could reveal private information.
Example: Before publishing a PDF report publicly, sanitise it to remove the author’s name, internal comments, and revision history that were added automatically.
108. Decrypt PDF
What it does: Remove the password protection from a PDF (for files you have permission to unlock).
Example: You have your own password-protected PDF but want to share it without a password. Decrypt it to remove the password and make it openly accessible.
109. Flatten PDF
What it does: Make all form fields and annotations permanent and non-editable. The PDF looks the same but no one can change the form fields anymore.
Example: A filled application form PDF is ready to be submitted. Flatten it before submitting so the filled data cannot be altered by the recipient.
110. Remove Metadata
What it does: Strip all hidden metadata from your PDF — author name, software name, creation date, GPS location, and more.
Example: Before sharing a PDF publicly, remove all metadata so no one can find out who created it, when, and with which software.
111. Change Permissions
What it does: Set exactly what others can and cannot do with your PDF — allow or block printing, copying, editing, and commenting.
Example: You share a training PDF with employees. Set permissions to allow printing but block copying of text and editing — so the content cannot be stolen or modified.
112. Digital Signature
What it does: Add a cryptographic digital signature to your PDF using an X.509 certificate. This is a legally valid, tamper-proof signature.
Example: A company director adds a legally binding digital signature to an official contract PDF before sending it – far more secure than a drawn signature.

Don’t skip the below part. How good would it be if you could extend this complete professional PDF toolkit to run privately, forever free, and especially offline – in short, directly on your own computer?
Well, you can do it all definitely using Docker Desktop. Before we start, and if you are unsure about what Docker Desktop is, here are the basics.
What is Docker?
In simple words, Docker is an open-source development platform that carries a complete app virtually to build, share, and run in a small box known as the container.
Moreover, Docker Desktop offers a GUI (graphical user interface / visual interface) to take full control of these containers in a simple way with the help of menus and buttons.
BentoPDF self-hosting using Docker
To leverage the power of the BentoPDF service by default, a user dives into the free and private www.bentopdf.com, but the Docker self-hosting for it can’t be ignored, as it offers a bunch of benefits:
After one-time setup, no internet is required, and it works fully offline
It runs on a private network that can be shared with a home or an office team
A user has full control, just like their own server
No internet latency at all and faster performance
It’s 100% free without any cost at at all
Pre-requisite for BentoPDF self-hosting using Docker
A Windows, Mac, or Linux computer
Internet connection (only for the first-time setup)
About 200–300 MB of free disc space
10–15 minutes of your time
How to Setup BentoPDF Self-Hosting Using Docker Desktop
Docker Desktop, a free visual app, will be used to run BentoPDF offline.
STEP 1 — Download Docker Desktop
Docker Desktop is the free visual app we will use to run BentoPDF.
1.2 Click the big “Download Docker Desktop” button.
Here, I choose ‘Download for Windows – AMD64‘ for my computer
1.3 After downloading, open the installer file and follow the on-screen setup steps
(just click Next → Next → Finish like any normal app installation).
1.4 After installation is complete, open Docker Desktop from your Start Menu (Windows) or Applications folder (Mac).
1.5 Docker Desktop will show a welcome screen. You can skip the sign-in — a Docker account is not required for this setup.
You will see the below icon (white Docker) appear in your taskbar (Windows) or menu bar (Mac). That means Docker is running.
STEP 2 — Understand the Docker Desktop Interface
When Docker Desktop opens, you will see a left sidebar with these sections:
Section
What It Does
Containers
Shows all running and stopped apps
Images
Shows all downloaded app packages
Volumes
Storage areas for apps
Dev Environments
For developers (you can ignore this)
We will mainly use the Images section and the Containers section.
STEP 3 — Search for the BentoPDF Image
An “image” in Docker is like a ready-made app package that you download once and run anytime.
3.1 In Docker Desktop, look for the search bar at the top of the window.
It usually says “Search images, containers, volumes…”
3.2 Click on the search bar and type exactly:
ghcr.io/alam00000/bentopdf-simple:latest
This is the official, free BentoPDF self-hosted image from the BentoPDF team.
3.3 In the search results, look for bentopdf-simple and click on it.
3.4 You will see an option to Pull the image. Click Pull.
Docker will now download the BentoPDF app package to your computer. This may take 1–3 minutes depending on your internet speed. You will see a progress bar.
3.5 Once the download is complete, you will see the image appear in the Images tab on the left sidebar.
STEP 4 — Run BentoPDF as a Container
Now we will “run” the image — this starts the actual BentoPDF app on your computer.
4.1 In Docker Desktop, click on Images in the left sidebar.
4.2 Find the bentopdf-simple image in the list.
4.3 Click the Run button (▶️ play icon) next to it.
4.4 A popup window will appear with settings. You need to fill in one important field:
BentoPDF is back up instantly — no re-downloading, no re-setup needed.
STEP 7 — How to Update BentoPDF to a Newer Version
When a new version of BentoPDF is released, updating is easy:
7.1 Open Docker Desktop → click Images
7.2 Find bentopdf-simple in your images list
7.3 Click the three-dot menu (⋮) next to the image
7.4 Select Pull — this downloads the latest version
7.5 Go to Containers and stop the current bentopdf container
7.6 Delete the old container (click the trash icon 🗑️ next to it)
7.7 Go back to Images and run the new version fresh (same steps as Step 4)
STEP 8 — How to Remove BentoPDF Completely
If you ever want to fully remove BentoPDF from your computer:
8.1 Open Docker Desktop → Containers
8.2 Stop the bentopdf container, then click the Delete icon 🗑️
8.3 Go to Images
8.4 Find bentopdf-simple, click the three-dot menu (⋮) → Remove
BentoPDF is now completely removed. Clean and simple.

Troubleshooting — Common Problems and Fixes
Problem 1: Docker Desktop does not start
Solution: Make sure your computer meets the minimum requirement.
Windows: Windows 10 64-bit or newer
Mac: macOS 12 (Monterey) or newer
Also make sure you restarted your computer after installation.
Problem 2: Port 3000 already in use
Solution: During Step 4, choose a different Host Port number — like 3001 or 8090. Then access BentoPDF at http://localhost:3001 instead.
Problem 3: BentoPDF page does not open
Solution: Check the Containers tab in Docker Desktop. If the container shows “Stopped” status, click the Start (▶️) button to run it again.
Problem 4: Image pull fails
Solution: Check your internet connection. Also make sure Docker Desktop is fully running (the whale icon should be visible in your taskbar, not loading).
Problem 5: Advanced tools like Office-to-PDF not working
Solution: This is expected over plain HTTP. Advanced features need HTTPS. For personal and home use, all core tools will work fine at http://localhost:3000.
