How it works

  1. 01

    Choose a file for Merge PDF. It accepts PDF. Most files stay in this tab.

  2. 02

    Set the options on the workbench — preview, crop or timeline when this tool has one — then press Run.

  3. 03

    Download the result. It is also saved in your tray so the next tool can pick it up without another upload.

About this tool

Pages are copied as objects, so text remains selectable, forms and links are preserved and image quality is untouched. Add files with the button or drag them in; remove any you added by mistake before pressing Run. Everything happens on your device.

Questions

What can I open in Merge PDF?
Merge PDF accepts PDF. Older video containers such as AVI, WMV, FLV, MPEG and 3GP are decoded by the server encoder.
Does Merge PDF upload my file?
Most MP4, WebM, images and PDF stay in this tab. Instagram/TikTok crops, DVD, GIF, iPhone presets, stabilize, hard containers (AVI, WMV, HEVC) and a failed local encode go to the server encoder. The file is processed and discarded — we do not keep a copy.
How large can the file be?
Free: 500 MB and 8 exports a day. Plus (waitlist) raises the daily cap. A pasted public file URL is also accepted.
