Add Page NumbersWhat PDF Toolkit Is
PDF Toolkit is a small collection of single-purpose PDF tools that run inside your web browser. Each one solves a task that comes up when paperwork has to be sent somewhere: joining separate documents into one attachment, pulling out the two pages someone actually asked for, getting a file under an upload limit, or turning photos of a form into something a portal will accept.
It exists because these jobs normally push people towards installing desktop software they will use twice a year, or towards uploading private documents to a service in exchange for an email address. Neither is necessary for tasks a modern browser can already perform on its own hardware.
Processing happens on your device
Each tool loads a small program into the page, and that program opens your file in your browser's memory, builds the result there, and passes it to your downloads. No copy of your document is sent to a server, so there is nothing for us to store, read or delete later.
Nothing to sign up for
There is no account, no email confirmation and no free trial that expires. You open a tool, use it, and close the tab — what you did is not attached to any identity.
Works on whatever you already have
A current version of Chrome, Edge, Firefox or Safari is all that is needed, on Windows, macOS, Linux, Android or iOS. Nothing is installed and no administrator rights are required.
Free, without limits we invented
No page caps, no watermarks and no daily quota. The real limits are your device's memory and the 100 MB file ceiling some tools apply so mobile browsers stay stable.
Choose the Right PDF Tool
Find the sentence that sounds like your situation and start there. Each entry says what the tool does to your file and what it cannot do, so you can tell before uploading anything whether it is the right step.
“I have several PDFs and need to send one file.” → Merge PDF
Add the documents, drag them into the reading order you want, and download a single PDF. Pages are copied as they are, so text stays selectable and scans keep their resolution.
Open Merge PDF“I only need certain pages from a long PDF.” → Split PDF
Tick the pages you want in the thumbnail list and extract them into one new document, or break every page out into its own file. Removing pages is also the cleanest way to make a file smaller, because nothing is re-encoded.
Open Split PDF“My PDF is too large to email or upload.” → Compress PDF
Compression keeps the content and reduces the weight. A gentle pass rewrites the file structure and leaves text sharp; the strongest setting redraws pages as images, which shrinks far more but ends searchable text.
Open Compress PDF“I have photos or camera scans and need a PDF.” → JPG to PDF
Each image becomes one page at its own proportions, so nothing is cropped, and you set the order before converting. Photo pages are heavy by nature, so this pairs naturally with compression afterwards.
Open JPG to PDF“I need PDF pages as images I can paste or post.” → PDF to JPG
Choose the pages and a quality level, then download them individually or as a ZIP. The output is a picture, so text on it can no longer be selected or searched — pick a higher quality if it will be printed or zoomed.
Open PDF to JPG“I need to edit the wording inside a PDF.” → PDF to Word
The text layer is read out and rebuilt as an editable .docx with paragraphs and likely headings. It recovers wording, not a pixel-perfect layout, and a scan with no text layer cannot be converted this way.
Open PDF to Word“I need to share a Word document as a PDF.” → Word to PDF
A .docx file becomes a PDF that opens the same way for every recipient, with no risk of fonts reflowing or someone editing it by accident. Text, headings and lists carry over; complex layouts are simplified.
Open Word to PDF“My scanned pages are sideways or upside down.” → Rotate PDF
Turn individual pages or the whole document in 90° steps and see the change in the thumbnails before saving. The orientation is written into the file, so it stays corrected wherever it is opened.
Open Rotate PDF“I need numbered pages before printing or submitting.” → Add Page Numbers
Numbers are drawn into the margin in the position you choose, with your own starting number and text size — useful when a document is one section of a larger bundle.

Using Two Tools Together
Real document tasks often need two steps, and the order usually matters. These are the combinations that come up most, with the reason each sequence runs the way it does.
Photos of paperwork into one acceptable upload
JPG to PDF → Merge PDF → Compress PDF
Camera shots of receipts or a signed form become PDF pages, the pages join the rest of the file, and a final compression brings the result under the portal's size cap. Photo pages are the heaviest kind, so the last step is usually the one that matters.
An application packet from separate exports
Merge PDF → Add Page Numbers → Compress PDF
A resume, a cover letter and certificates become one ordered document, continuous numbering makes it easy to reference in an interview, and compression only comes in if the combined file is rejected for size.
Sending one section of a long report
Split PDF → PDF to JPG
Pull the pages that matter out of a long document, then turn them into images if they are going into a chat, a slide or a post rather than an attachment.
Fixing a scan before anyone else reads it
Rotate PDF → Compress PDF
Straighten pages the scanner captured sideways, then shrink the file if the scan was made at a high resolution. Rotating first means the thumbnails you check are the ones the recipient will see.
Finishing a document written in Word
Word to PDF → Add Page Numbers
Convert the finished .docx so the layout stops moving between computers, then add numbering if the original did not carry it. Doing it in this order avoids two competing sets of numbers on the page.
Reusing a PDF you no longer have the source for
PDF to Word → Word to PDF
Recover the text into an editable document, make the changes, and convert back. Expect to tidy the formatting by hand — this route restores wording, not the original design.
How It Works
PDF Toolkit performs document work directly inside your browser. Selecting a file gives the open page temporary access to read it on your device; the document is not sent to a processing server. That matters for resumes, contracts, financial records and identity documents because their contents stay on the computer or phone you are already using.
The pattern is simple: choose the files, review their previews or order, adjust the settings the tool offers, and start the task. Your browser builds the new PDF, Word file, JPG images or ZIP archive in memory and hands the finished result to its normal download function.
Processing speed depends on the file and your device. A short text PDF may finish almost immediately, while a long, image-heavy scan takes more memory and time. The selected files and temporary result disappear from the page when you reload or close the tab; your original files are never changed.

Common Use Cases
These are everyday document problems where a small, focused tool is usually faster than installing a full PDF editor.
Prepare one job-application attachment
Merge a resume, cover letter, diploma and references in the order a recruiter should read them, then download one PDF for the application portal.
Meet an email or upload limit
Compress a large scan or photo-heavy report when a mailbox or online form rejects the original file for being too large.
Turn photographed paperwork into a document
Convert phone photos of receipts, signed forms or certificates into one ordered PDF instead of sending a loose group of images.
Share only part of a long document
Split a contract, statement or report to extract the pages a recipient needs without sending unrelated or private pages.
Tips for Best Results
Work toward a real size limit
Before compressing, check the maximum accepted by the email service or form. Start with Recommended and only use stronger compression if the result is still too large.
Check order before sending
After merging, open the downloaded PDF and scan the first and last page of each document. This catches reversed scans and misplaced attachments quickly.
Use readable source files
Conversion cannot restore detail missing from a blurry photo. Photograph paper in even light, keep the camera parallel, and confirm small text is legible first.
Remove passwords before processing
Encrypted, incomplete or damaged PDFs are common reasons a tool cannot open a file. Unlock it in your usual PDF reader and save a fresh copy before trying again.
Split very large jobs
Browser processing uses your device's memory. If an older phone struggles with a long scan or many high-resolution photos, process smaller batches and merge the results.
Keep the original
Every tool creates a new download, so retain the source file until you have opened the result and checked its pages, quality and settings.

Your Documents Are Yours
All nine tools run inside your web browser. When you choose a file, the page reads it from your device, builds the result in memory and passes it straight to your downloads — no document is uploaded to a server for processing, so there is nothing for us to store, read or delete later. Reloading or closing the tab clears whatever you had selected.
It is worth separating that from ordinary website data. Loading these pages is a normal web request, so our hosting provider sees technical details such as an IP address and a browser type, and the site uses Google Analytics for anonymous visit counts and Google AdSense for the adverts that pay for hosting. None of those services receive your files, their names or their contents.

What can I do with this PDF tool?+
You can merge several PDF files into a single document and choose their order, split a PDF by extracting selected pages or turning every page into its own file, compress a PDF to reduce its size, convert between PDFs and JPG images, turn a PDF into an editable Word file or a Word file into a PDF, rotate pages and add page numbers.
Is the PDF merger free?+
Yes. The merge tool is completely free, with no account, no sign-up and no page or file limits imposed by us.
Can I merge multiple PDF files?+
Yes. Add as many PDFs as you need, reorder them with the up and down arrows, remove any you do not want, then download one combined PDF.
Can I use the tool on my phone?+
Yes. The site is responsive and the merge tool works in modern mobile browsers. Very large files depend on the memory available on your device.
Do I need to install software?+
No. Everything runs in your web browser — there is nothing to download or install.
Are my files stored?+
No. Merging happens locally in your browser, so your PDFs are never uploaded to our servers and nothing is stored. Closing the page clears the files you selected.
Why do I not need an account?+
There is nothing for an account to hold. Because the work happens on your device and no file is kept afterwards, there is no library to sign into and no history to protect, so no email address is ever requested.
Is there a limit on how many files I can process in a day?+
No daily quota is applied and there are no watermarks. The only practical limits come from your own device: most tools accept files up to 100 MB, and page previews are generated for the first 60 pages so long documents stay responsive on phones.
What happens if my internet connection drops mid-way?+
The page needs a connection to load the first time. Once the tool is open and your file is selected, processing continues locally even if the connection fails, because no data is being sent anywhere.
Can I use the tools on a work or school computer?+
Usually yes, since nothing has to be installed and no file leaves the machine. That is often the deciding factor where IT policy forbids installing desktop PDF software or uploading documents to outside services.
Will the tools work with a password-protected PDF?+
Encrypted files may refuse to open, and you will see a message rather than a broken result. Remove the password in whatever reader you normally use, then bring the file back here.
How is the site paid for if everything is free?+
The pages carry advertising, which covers hosting. That is also why no file is ever uploaded or sold — the documents you process are never seen by us in the first place.
