How the PDF page number tool works

Go to the PDF page number tool.

  1. Upload your PDF file

  2. Choose page number position (top/bottom, left/center/right)

  3. Customize format (1, 2, 3 or 1 of 10, Page 1, etc.)

  4. Choose font size and style

  5. Click Add Page Numbers

  6. Download the numbered PDF

Everything happens in your browser. No server upload, no account needed.

Common pitfalls and solutions

Pitfall 1: Page numbers on wrong pages

Adding page numbers to the wrong pages or in the wrong order.

Solution: Preview the page number placement before applying. Most tools show a preview of each page.

Pitfall 2: Page numbers cover important content

Page numbers placed over text or images can make documents hard to read.

Solution:

  • Choose margins with sufficient white space

  • Use smaller font sizes (8-10pt)

  • Position page numbers in corners or center of margins

Pitfall 3: Starting page number at wrong number

Page numbers may start at 0 or skip numbers.

Solution:

  • Check the "Start from" setting

  • Set starting number to 1 (or 0 if needed)

  • Verify the sequence in the preview

Pitfall 4: Inconsistent formatting

Different pages may have different page number styles.

Solution:

  • Apply the same format to all pages

  • Use consistent font and size

  • Check each page in the preview

Pitfall 5: Page numbers on cover page

You may not want page numbers on the cover or title page.

Solution:

  • Use "Exclude first page" option if available

  • Or add page numbers starting from page 2

  • Some tools support different numbering for different sections

How to Compress PDF Files Online for Free (Without Uploading to a Server)

  PDF files have a tendency to balloon in size. A simple resume with a few high-resolution images can easily hit 20MB. A scanned contract with multiple pages? That can reach 50MB or more. When you need to email a file, upload it to a job portal, or submit it through an online form, size limits become a real problem. The good news: compressing PDFs is easy. The bad news: most online tools force you to upload your file to their servers first — which is a privacy risk if you're dealing with contracts, resumes, or financial documents. In this guide, I'll show you how to compress PDF files for free, without ever uploading them to a third-party server. Method 1: Built-in OS Tools (No Upload, Limited Control) Windows Right-click your PDF file Select Print Choose Microsoft Print to PDF as the printer Click Print and save the new file This creates a compressed version, but you have no control over the compression level. Sometimes it works well; other times it over-compresses and blurs...

How to Convert PDF Pages to High-Quality Images

  I do this all the time. Need to put a PDF chart into a PowerPoint. Want to share a single page from a report on Slack. Or insert a contract page into a Word doc. Copy-paste from a PDF viewer? Looks terrible. Screenshots? Even worse, blurry and cropped wrong. Converting PDF pages to actual image files — PNG or JPEG — is the clean way. And you don't need Photoshop or any paid software. The Built-In Way (Mac Only) If you're on a Mac, Preview actually does this. Open the PDF in Preview. Go to File → Export. Pick a format (JPEG, PNG, TIFF). Choose a resolution. Done. The problem? It's one page at a time. For a 20-page document, you'll be there all day. And the quality control is hit or miss — sometimes the text looks soft around the edges. Still, for a single page, it's fine. The Windows Way (Kinda Clunky) Windows doesn't have a native PDF-to-image converter. Your options are: Print to PDF and then... wait, that's a loop. Copy from Edge/Chrome: Open the PDF in...

How to Merge PDF Files Online for Free (No Software, No Upload)

  I merge PDFs almost every week. A client sends three separate invoices. My bank statements come as twelve individual files. A project report is split into five chapters by different people. For years, my options were bad. Adobe Acrobat costs money. Free online tools force me to upload files to their server first. And the "print to PDF" trick? Messy, slow, and the bookmarks always break. So I built a better way: open the browser, drop the files, reorder them, download one merged PDF. Nothing uploads anywhere. Why Most PDF Merge Tools Feel Wrong Adobe Acrobat: Powerful, but $20/month. Overkill if you just need to combine a few files. Free online merge tools: Most work the same way — upload all your PDFs to their server, they combine them, you download the result. Your tax documents, your client contracts, your medical forms — all sitting on a server you don’t control. Even if they claim to delete files after an hour, the upload itself is the risk. Print to PDF: Works in a ...
