Qoppa Software, which specializes in PDF tools, has updated PDF Studio (http://www.qoppa.com/psindex.html), a PDF editor, to version 6.2. The new version adds PDF review and edit functionality to Google Docs.

The software can now open, edit and save documents directly from and to Google Docs. Additionally, it provides an integrated Google Docs file manager to upload, download and share files or whole folder structures.

PDF Studio maintains full compatibility with the PDF Standard and supports the latest PDF format. In version 6.10 you can: manage digital IDs and trusted certificates for digital signatures; batch preflight to preflight to verify PDF/X compliancy for multiple documents at once; and batch crop to crop multiple documents at once and change the margins for crop box, bleed box, trim box or art box.

PDF Studio offers cloud annotation and a screenshot tool allowing users to select a page area with a lasso and copy the image to the clipboard or export the image to a file. There's also support for barcodes.

PDF Studio is available for Mac, Windows and Linux platforms. It comes in two flavors: PDF Studio Standard at $60 and PDF Studio Pro at $95.
