Merge, split and shrink real PDFs, right here in your browser.

✅ Your merged PDF is ready
Step 1: add one PDF. Step 2: type the pages you want to keep.
Use page numbers and ranges, separated by commas. Pages come out in the order you list them.
✅ Your new PDF is ready
Step 1: add one PDF. We rebuild it cleanly and re-encode its photos smaller, then show you the true before and after sizes.
Honest note: text and line art are never rasterized or blurred. If a PDF is already tightly compressed, we will tell you plainly that we could not make it smaller instead of pretending.
✅ Done

How it works
Tap a tab, add your PDF, and press the big button. Merge joins files in the order shown (use the arrows to rearrange). Split extracts the pages you type, like 1-3, 5. Compress rebuilds the file cleanly and re-encodes its photos smaller, then shows the true sizes. Everything runs on your device only.
