File Size Upload Limits
Large files may affect upload speed, processing time or extraction reliability. WordBinary supports up to 20,000 words per document for AI, plagiarism and combined checks. ZIP upload is available only for enabled institutional workflows.
Why file size matters
File size can affect how quickly a document uploads, how long processing takes and how reliably the system can extract text. Very large files may contain heavy formatting, embedded objects or other features that make them harder to process. Even where uploads are supported, larger files may require more patience during status updates.
Word and ZIP limits
AI, plagiarism and AI + plagiarism checks support up to 20,000 words per document. ZIP upload is intended for enabled Teacher, Supervisor and Admin workflows. Each supported file inside the ZIP is processed independently, so a ZIP containing many large files can take considerably longer than a single upload.
Supported document formats
Supported formats include DOC, DOCX, RTF, ODT, PDF, PPTX, PPSX, PPS, TXT, HTML, HTM, XLS and XLSX. Extraction quality may still depend on how the file was created, whether text is selectable and whether the document contains scanned images or complex embedded content.
What can make a file unusually large
A file may be large not only because of word count, but because of embedded images, charts, text boxes, comments, tracked changes or repeated formatting layers. A document with moderate text length may still be very large if it contains heavy embedded content.
How to reduce upload issues with large files
If a file seems unusually large or slow to upload, a simplified copy may help. Removing unnecessary formatting or embedded objects can improve reliability.
How large files may affect processing
Larger files may spend longer in queued or processing status. This does not automatically indicate a problem. Users should allow time for status updates before assuming the upload failed.
What to do if the file seems too large
If you suspect file size is causing issues, save a simplified version and retry. If the issue persists, contact WordBinary support and mention the approximate file size and what happened during upload.
How WordBinary support can help
If you are unsure whether file size is causing a problem, WordBinary support may help review the issue. Users can also check related guides on upload failures, text extraction and report status.
Best practice before upload
Before uploading, review whether the file contains unnecessary formatting, save a clean copy and use a stable internet connection. This can reduce upload and processing issues.
