Mac users have Preview built-in for basic PDF tasks, but it lacks compression, OCR, merging, and advanced annotation. pdfeditor.onl fills all those gaps — for free, directly in your browser.
Apple's Preview handles basic PDF viewing and signature placement, but it cannot compress PDFs, run OCR on scanned documents, merge files with drag-and-drop reordering, split by custom page ranges, add watermarks, or add page numbers. For all of these, you need a more capable tool.
Open Safari or Chrome on your Mac and go to pdfeditor.onl. You get a full-featured PDF editor with compression, OCR, text editing, eraser, image overlay, watermarks, page numbers, merging, splitting, reordering, signing, and file conversion — all running locally in your browser at no cost.
Use Preview for quick signatures and PDF viewing. Use pdfeditor.onl for everything else: compressing before emailing, merging multiple PDFs, running OCR on scans, or converting formats.
Tip: On macOS, you can drag a PDF file directly from Finder and drop it onto the upload area in pdfeditor.onl in any browser for the fastest workflow.
