Check the requirements
For example, a 200 KB limit, JPG format and a 600 × 800 px maximum are separate requirements. Check file size, dimensions and accepted formats individually.

BEFORE YOU SUBMIT
One last check before you submit
Inspect the output
Inspect small text, faces, backgrounds and page order. A converted file does not guarantee acceptance by a website or organization.
Keep your original
Keep the downloaded output separate from your original. Closing or reloading this tab clears the workspace and its results.
Common questions
How are pages ordered?
All pages from the first file come before all pages from the next file. Selecting individual pages is not supported. Check file order before merging.
Are digital signatures and forms retained?
Not guaranteed. Keep the original when signatures or form behavior matter. Download and check every page before sharing a merged document.
Can I merge encrypted PDFs?
No. This app does not unlock files or bypass security. Choose ordinary, unencrypted PDFs. Damaged files may also fail.
