Zoho PDF Editor is a free tool for editing, organizing, and sharing PDF documents. The online editor supports rich-text formatting, text and image overlays, shapes, highlighting, white-out, QR codes, barcodes, hyperlinks, and watermarks. Page tools can combine, split, extract, rotate, and replace pages. Users can create fillable and signature fields, fill and sign PDFs, and collect data and digital signatures. Shared documents can allow viewing, commenting, editing, or further sharing. The online editor imports files from Zoho WorkDrive, Dropbox, Box, and OneDrive, and exports PDFs, fillable PDF forms, password-protected PDFs, JPEG, and PNG. A free desktop app works on the device without internet access; Zoho lists Windows and macOS apps and says PDF Editor is among its Linux desktop apps. The online editor requires a Zoho account. Its dashboard accepts PDFs up to 50 MB or 150 pages and does not accept encrypted or password-protected files. Zoho also offers cloud-based PDF editing APIs for editing, page organization, forms, compression, metadata, and password protection.
