pdfmix

Merge PDFs and mix their pages

Combine up to 20 PDFs into one file. Every page from every file lands in a single grid, so you can interleave, reorder, and trim before you download.

Rearrange, delete, rotate, crop and censor pages — from one or many PDFs into one file.

    Draw a rectangle on the page. Drag to move it, use the handles to resize.

    Make censoring permanent?

    Censored pages are converted to images, so the hidden content is permanently removed and cannot be selected, copied, or recovered. Text on those pages will no longer be selectable.

    Edit history

    Every action is listed newest first. Click an entry to revert to that point — greyed entries were undone and can be re-applied the same way.

      3. Click export and download one merged PDF.

      Frequently asked questions

      Can I do more than glue files together?

      Yes. Unlike plain merge tools, pdfmix shows every page of every file in one grid. You can interleave pages, drop the ones you don't need, rotate, crop, and censor — then export once.

      Can I merge password-protected PDFs?

      Yes. Enter the password when you add the file. The exported PDF is unlocked.

      How many files can I merge?

      Up to 20 files in one session, with a total of 1,000 pages and up to 300 MB per file.

      Where do my files go when I merge them?

      They travel over an encrypted TLS connection to our servers, where they live for at most 2 hours. Delete now removes them instantly, and they are never used to train AI.

      Does merging change the quality of my pages?

      No. Pages are copied into the merged PDF unchanged, keeping their original quality and selectable text.
