A browser-based suite for compressing, merging, splitting, converting, editing, and reorganising PDFs.

Landing page captured for the 2026-08-30 issue.

Field notes

The tool is organised around four jobs: compression, page arrangement, image conversion, and lightweight markup. Its sharpest constraint is target-size compression, which the page says can produce a file within 2% of a requested limit such as 200 KB or 1 MB. Other listed operations include extracting page ranges, setting image-PDF margins and page size, choosing JPG quality, and controlling watermark angle and strength.
