Frequently asked questions

Are my files uploaded?

No. With this tool, your file never leaves your device. Even with Google Drive or Dropbox, it comes straight from your cloud to you, without passing through us.

Are bookmarks and quality preserved?

The pages are taken over unchanged, so quality, fonts and vectors stay 100% intact. Document-wide bookmarks from the source files are not carried over into the merged document.

Are there limits on file size or page count?

The main limit is your device, because that is where the work happens. Files up to 100 MB work reliably. With very large files, an older smartphone needs a little patience.

Is the tool free?

Yes. All tools on Gatefrog are free to use, with no sign-up, no installation and no watermark from us.
