Free Online PDF Tools in Your Browser
This PDF toolkit covers the common tasks people actually need: compressing oversized PDFs to fit email limits, merging multiple PDFs into one file, splitting large PDFs into smaller ones, converting between PDF and other formats (Word, images, Markdown), and extracting pages or text. Each tool runs inside your browser so your documents stay private.
That privacy matters for contracts, bank statements, tax returns, medical records, and unpublished reports. Most free PDF tools online upload your files to a third-party server — ours do not. Drop a PDF in, work with it, and download the result without anything leaving your device.
Why These PDF Tools
Documents Stay Private
PDFs are processed locally with PDF.js and client-side scripts. Nothing is uploaded, so sensitive documents remain on your device.
No Account Needed
Open any tool and start using it. No signup, no email confirmation, no usage limit, no trial period.
Preserves Document Quality
Merging, splitting, and extraction keep original quality exactly. Compression offers adjustable quality levels so you control the tradeoff.
Fast for Typical Files
Most PDFs process in seconds. No upload wait, no queue, no server delay.
Common PDF Tasks
These are the PDF jobs most users come here for:
- Compressing a scanned PDF before attaching it to an email to stay under size limits.
- Merging several signed PDFs, receipts, or chapters into a single document for submission or archiving.
- Splitting a large PDF into individual pages or smaller sections for sharing.
- Converting a Markdown document into a clean PDF for print or distribution.
- Extracting specific pages from a longer PDF without opening a full PDF editor.
How to Use the PDF Tools
Every PDF tool follows the same workflow:
- Pick a tool. Select the compressor, merger, splitter, or converter from the cards above.
- Load your PDFs. Drop one or more PDF files into the tool. Batch operations are supported where relevant.
- Download the result. Adjust settings if needed, run the tool, and save the output — fully processed in your browser.
PDF Tools FAQ
Are my PDFs uploaded anywhere?
No. Every PDF tool runs locally in your browser. Your documents never touch a server, and nothing is stored after you close the page.
Can I compress password-protected PDFs?
You need to unlock the PDF first using the owner password. Once unlocked, the file can be compressed, merged, or split like any other PDF.
Will the tools change my original PDF?
No. All tools produce a new output file. Your original PDF stays untouched on your device.
Is there a file size limit?
No server limit since nothing is uploaded. Very large PDFs are limited by your device memory — typically phones handle less than desktops.
Does compression reduce readability?
Low compression keeps images and text sharp. Aggressive compression may soften embedded images slightly but text stays crisp. You choose the quality setting.
