Clear, concise answers
Frequently asked questions
Is my PDF uploaded?＋
No. The document is read and rebuilt in your browser.
Are password-protected PDFs supported?＋
No. Remove protection lawfully in an application where you have the password and owner permission.
Will digital signatures remain valid?＋
Changing pages normally invalidates an existing digital signature. Verify and sign the final document again in an appropriate system.
What are the limits?＋
One PDF can be up to 30 MB and 500 pages. Merge accepts up to 20 files with a combined limit of 100 MB.
Why can a large file take longer?＋
All work uses your device memory and CPU, so speed depends on the browser, page count and embedded images.
Is page quality reduced?＋
Existing PDF pages are copied without rasterization. JPG-to-PDF embeds the source images at their actual quality.
