# 10 Essential PDF Tools Everyone Should Know
I used to pay a monthly subscription for PDF software. Then I realized my browser could do almost everything I was paying for — for free, without uploading my documents to anyone's server. Here are the ten PDF tools I genuinely use, and when each one saves the day.
1. Merge PDF
Got five separate files that need to be one document? This is the tool. I use it constantly for visa applications, where they want your passport, bank statement, and letters as a single PDF.
2. Split PDF
The opposite problem: someone sends you a 90-page PDF and you only need pages 12 to 15. Split it, take what you need, move on.
3. Compress PDF
Scanned documents are the worst offenders — a ten-page scan can easily hit 40 MB. Compression gets it under email limits without turning the text unreadable.
4. Rotate PDF
Someone scanned a document sideways. It happens more often than it should. One click fixes it permanently instead of tilting your head every time.
5. Add Page Numbers
Essential for anything long that you'll discuss with other people. "Look at page 34" beats "scroll down a bit, no, further" every single time.
6. Watermark
If you're sending a draft contract or a portfolio piece, a "DRAFT" or "CONFIDENTIAL" watermark across each page makes the status unmistakable.
7. Crop PDF
Scanned pages often come with huge white margins or a shadow of the scanner lid. Cropping cleans them up and makes the document look professionally made.
8. Images to PDF
Phone photos of receipts, handwritten notes, signed forms — select them all, get one tidy PDF. I do this for expense reports every month.
9. PDF to JPG
Sometimes you need a page as an image — for a presentation slide or a social post. This pulls each page out as a picture.
10. Repair PDF
Occasionally a PDF gets corrupted in transit and refuses to open. Before panicking, try the repair tool — it fixes more files than you'd expect.
The best part
Everything runs in your browser. Your documents never leave your device, which matters a lot when the PDF in question is a bank statement or a contract. No uploads, no accounts, no waiting in a queue behind other people's files.
