Why Choose SimplyUtils Over iLovePDF?

iLovePDF uploads your files to their servers for processing, which means your sensitive documents leave your device. SimplyUtils processes everything locally in your browser — nothing is ever uploaded. Plus, SimplyUtils offers page-level selection, image merging, and bookmark creation for free, while iLovePDF limits free users to 25 files and lacks these advanced features entirely.

Why Choose SimplyUtils Over SmallPDF?

SmallPDF limits free users to 2 tasks per day and requires an account. SimplyUtils has no daily limits, no account requirement, and — unlike SmallPDF — never sends your files to a server. You also get features SmallPDF doesn't offer, like page-by-page selection with thumbnails and automatic bookmarks.

Why Choose SimplyUtils Over PDF24?

PDF24 is a solid free tool, but it uploads files to its servers for processing. SimplyUtils keeps everything in your browser. Additionally, SimplyUtils lets you merge images alongside PDFs, select individual pages, sort files by name or size, and add bookmarks — features PDF24's merger doesn't have.

Why Choose SimplyUtils Over Sejda?

Sejda caps free usage at 50 pages and 3 tasks per hour, and charges for bookmarks and advanced page selection. SimplyUtils gives you all of these features for free with no limits, and does it entirely in your browser for maximum privacy.

Common Use Cases

  • Document Compilation — Combine chapters, reports, or research papers into one PDF.
  • Application Packages — Merge resume, cover letter, certificates, and references.
  • Invoice Management — Combine monthly invoices into a single file for accounting.
  • Mixed Media — Merge scanned images (JPG/PNG) together with existing PDFs.
  • Double-Sided Printing — Use the blank page toggle so each document starts on a front page.
  • Organized Navigation — Enable bookmarks so readers can jump between sections in the merged PDF.

How PDF Merging Works

PDF (Portable Document Format) files contain pages, fonts, images, and metadata. When you merge PDFs, the tool copies selected pages from each source file into a new document while preserving all content, formatting, and quality. Since SimplyUtils uses pdf-lib (a JavaScript PDF library), everything runs in your browser — no server round-trips, no waiting, and no privacy concerns.

Upload your PDF and image files above, arrange them in your desired order, select the pages you want, and click merge. Your merged PDF downloads instantly — all without leaving your browser.
