The 6 PDF Tools at a Glance

PDF Merger — Combine multiple PDFs into one
PDF Splitter — Extract specific pages from a PDF
PDF Compressor — Reduce file size while preserving quality
PDF to Image — Convert pages to PNG or JPG
Image to PDF — Convert images into a PDF document
PDF Page Rotator — Rotate individual pages to any angle

Each tool serves a distinct purpose, but they’re most powerful when used together. A common workflow: split a large PDF to extract the pages you need, rotate any sideways pages, merge them with other documents, compress the result, then convert to images for sharing.

PDF Merger: Combine Multiple Files

The PDF Merger joins two or more PDFs into a single document. Drag files into the order you want, and the tool combines them instantly.

💡 Tip
Always include -webkit-backdrop-filter alongside backdrop-filter for Safari support. Without the prefix, the effect is invisible to roughly 25% of mobile users.

When to use it

Pro tip: After merging, run the result through the PDF Compressor to reduce file size before emailing.

PDF Splitter: Extract Specific Pages

The PDF Splitter extracts individual pages or page ranges from a larger document. Select the pages you need and download them as a new PDF.

⚠ Warning
On iOS Safari, backdrop-filter inside a position: fixed element can cause severe scroll performance issues. Test thoroughly on real iOS devices.

When to use it

PDF Compressor: Reduce File Size

The PDF Compressor reduces PDF file size by optimizing embedded images and removing unnecessary metadata. Typical reduction: 40–70% without visible quality loss.

When to use it

PDF to Image: Convert Pages to PNG/JPG

The PDF to Image converter renders each PDF page as a high-resolution image. Choose PNG for lossless quality or JPG for smaller file sizes.

When to use it

Image to PDF: Create PDFs from Images

The Image to PDF tool converts one or more images into a single PDF document. Supports JPG, PNG, WebP, and other common formats.

When to use it

PDF Page Rotator: Fix Orientation

The PDF Page Rotator lets you rotate individual pages to any angle (90°, 180°, 270°). Essential for fixing scanned documents with mixed orientations.

When to use it
