Flatten a form before you send an RFI
Flatten a filled-in RFI, inspection form or daily report so the answers can't be changed and look the same for the architect, owner or inspector. Markups on drawings lock in the same way.

Questions
Why flatten a PDF?
Some apps hide markups or form answers. Flattening draws them into the page, so everyone sees and prints the same thing.
Do links still work?
Yes. Links stay clickable; everything else becomes part of the page.
Can I do several files at once?
Yes. Choose or drop several files. Each one gets the same settings, and you save them all in one ZIP.
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.
Does it work offline?
Yes. Once the page has loaded you can turn off Wi-Fi and the tool still works.
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.
