Questions

Can I change the order?

Yes. Drag a file, or use its arrow buttons, before you merge.

Does merging lower the quality?

No. Pages are copied as they are, with the same text, images and markups.

Are my files uploaded?

No. The tool runs in your browser, so your files never leave your device. Nothing is sent to us or kept after you close the tab.

Is it free?

Yes. There is no sign-up, no watermark on your file and no daily limit.

Is there a file size limit?

Only what your device can hold in memory. Most phones handle files of a few hundred MB; a computer handles more.

Need to mark up the PDF too?

Survey is a full PDF app for drawings. Add pens, shapes, clouds and count markers, and keep every sheet in sync on your computer, iPad and phone.
