File Editor is an online platform for editing, signing, converting, and managing PDF documents. Its browser-based tools require no downloads or extensions, offering a convenient way to work with files from a device or from Google Drive, Dropbox, or OneDrive. Users can edit text, add images and annotations, apply e-signatures, and organize pages by merging, splitting, rotating, extracting, adding, or deleting them. Other features include compressing, cropping, repairing, redacting, password-protecting, and unlocking PDFs, as well as adding watermarks and recognizing text with OCR.

File Editor also converts PDFs and other formats, including Word, Excel, PowerPoint, images, and text files. The service supports uploads up to 100 MB for PDFs and up to 20 MB for several other listed file types. Its workflow guides users through uploading a document, making changes, and downloading or sharing the result. File Editor describes its tools as fast, easy to use, and secure, and says files are processed on enterprise-grade servers. It also highlights privacy features such as password protection and encrypted storage.
