PDF Tools Guide

Merge PDF — Combine Multiple PDFs into One Document

Combining contracts, reports, and invoices into a single organized file saves time and prevents lost attachments. Mergio's Merge PDF tool stitches together multi-page documents directly inside your browser tab without any server uploads, preserving vector text, embedded fonts, and original image resolutions.

How to merge PDFs

  1. Click Merge PDF to open the workspace.
  2. Drop two or more PDF files into the upload zone.
  3. Drag file cards to set your preferred page order.
  4. Click Run and download your unified PDF document.
Is there a limit on how many PDFs I can merge?

There is no artificial cap. Merging happens in your device's memory using PDF-lib, easily handling dozens of documents in seconds.

Will merging reduce document quality?

No. Pages are merged as direct object streams without recompression, keeping text razor-sharp.

Pro Tip: Need to reorder specific pages inside the merged result? Use the Rearrange PDF Pages tool.

Split PDF — Extract Individual Pages into a ZIP Archive

When you only need specific sections or single sheets from a massive document, splitting breaks the file apart cleanly. This tool extracts every page into an independent PDF file and packages the collection into a convenient ZIP archive.

How to split a PDF

  1. Open the Split PDF tool.
  2. Drop in the multi-page PDF you want to separate.
  3. Click Run to extract all individual pages.
  4. Download and unzip your separated single-page PDFs.
How are split pages named?

Each page file is numbered sequentially (e.g., document_page_1.pdf, document_page_2.pdf).

Can I extract just a specific page range?

Yes, use the Extract PDF Pages tool to select custom ranges visually.

Rotate PDF — Fix Sideways or Upside-Down Pages

Scanned documents frequently end up in the wrong orientation. The Rotate PDF tool applies 90°, 180°, or 270° clockwise rotations across all pages in memory, permanently updating the orientation tag without re-encoding.

How to rotate PDF pages

  1. Upload your document to the Rotate PDF bench.
  2. Choose your rotation angle (90°, 180°, or 270°).
  3. Click Run to apply the orientation adjustment.
  4. Download the corrected, easy-to-read PDF.
Does rotating degrade text sharpness?

No, rotation modifies only viewport metadata in the PDF header without touching vector text or images.

Can I rotate individual pages?

Yes, open the Rearrange PDF Pages tool for visual page-by-page rotation.

Compress PDF — Shrink Heavy Scans & Document Files

Large scanned PDFs often exceed email size ceilings. Mergio's Compress PDF renders heavy image-based pages through an HTML5 Canvas pipeline, re-encoding graphic streams at optimized quality settings to slash file size while maintaining readability.

How to compress a PDF

  1. Select the Compress PDF tool.
  2. Drop in your oversized PDF document.
  3. Adjust the image quality slider (60%–75% is ideal for email).
  4. Click Run to download the compact document.
Which PDFs compress the most?

Scanned documents and image-heavy presentations see the largest size reductions (often 50%–80%).

Is searchable text preserved?

Scanned PDFs are optimized visually. For native digital PDFs with vector text, minimal re-encoding is needed.

PDF to JPG — Export High-Resolution Images from Pages

Turn document pages into standard JPG pictures for presentations, web posts, or photo albums. Each page is rendered via PDF.js onto a 2× high-DPI canvas and exported as a crisp JPG image inside a ZIP archive.

Numbering pages is essential for formal legal filings, academic papers, and business proposals. This tool stamps clear footer numbers (e.g. "Page 1 of 12" or "1") across all pages in standard Helvetica font.
