Supported Formats
This page lists exactly which files you can add to My Documents, how large they can be, and what you can expect once they are uploaded.
If a file type is not on this page, it will be rejected when you try to upload it.
What You Can Upload
When you click Upload in My Documents, your computer's file picker offers these types:
| Category | Formats |
|---|---|
| Documents | PDF (.pdf), Word (.doc, .docx) |
| Spreadsheets | Excel (.xls, .xlsx), CSV (.csv) |
| Presentations | PowerPoint (.ppt, .pptx) |
| Text | Plain text (.txt), Markdown (.md) |
| Images | PNG (.png), JPG/JPEG (.jpg, .jpeg), GIF (.gif), WebP (.webp) |
These are the formats My Documents is built around. If you have a choice of format, pick one from this table.
PDF is the safest choice. It keeps its layout everywhere and is read reliably. When a file is available in more than one format, upload the PDF.
Also Accepted
A few extra formats are accepted even though the file picker does not list them. You can add them by dragging the file from your computer onto the My Documents page:
| Category | Formats |
|---|---|
| OpenDocument | Text (.odt), Spreadsheet (.ods), Presentation (.odp) |
| Extra image types | TIFF (.tiff, .tif), BMP (.bmp) |
Because these types are not offered in the file picker, drag and drop is the way to add them. Everything else about them works the same as a regular upload.
Size and Upload Limits
| Limit | Value |
|---|---|
| Maximum size per file | 50 MB |
| Files in one multi-file upload | Up to 20 |
| Empty files | Not accepted — the file must have content |
| Duplicates | A file whose contents you already uploaded is rejected |
| Plan allowance | Uploads stop once your plan's document allowance is full |
| Upload frequency | There is an hourly limit on how many uploads you can start |
What you see when a limit is hit
| Message | What it means | What to do |
|---|---|---|
File too large | The file is over 50 MB | Split it into smaller files, or compress it |
Unsupported file type | The format is not on this page | Save or export the file as PDF and upload that |
Already uploaded | The exact same file content is already in your library | No action needed — the existing copy is already there |
Storage limit reached | Your plan's document allowance is full | Delete documents you no longer need, or ask your administrator about upgrading |
Maximum 20 files allowed | You selected more than 20 files at once | Upload them in smaller groups |
| "Empty files can't be uploaded. Please choose a file with content." | The file is 0 bytes | Check the file opens on your computer, then upload again |
Duplicate checking only looks at your own My Documents library. It does not compare your files against anyone else's.
See Uploading Documents for how single-file and multi-file uploads behave, including the progress modal and the Failed files list.
What's Not Supported
- Video files —
.mp4,.mov,.aviand other video formats cannot be uploaded. - Anything not listed on this page — only the formats above are accepted. Any other file is rejected with "File type not allowed."
If your upload is refused with a file-type message, converting the file usually solves it. Exporting to PDF works for almost any document, and saving an image as PNG or JPG works for almost any picture.
What Happens After Upload
Once a file lands in My Documents, its text is read automatically so that you and the AI can find and use it later.
- Small files are ready in seconds.
- Larger files finish in the background — you can keep working while they do.
- For images, the text inside the picture is read too, so scanned pages, whiteboard photos and screenshots become searchable.
Occasionally, reading the text inside an image may be skipped if that service is briefly unavailable. The upload still succeeds and the file is stored.
Preview Without Downloading
Click any document card in My Documents to open the built-in preview. Most formats can be read directly in the app, so you do not have to download the file first.
| Format | What the preview shows |
|---|---|
PDF (.pdf) | The pages, rendered as they look |
Word (.docx) | A formatted preview of the document |
Word (.doc, older files) | The text that was read from the file |
Excel (.xlsx) | A spreadsheet grid, opened in a wide window |
PowerPoint (.pptx) | A slide preview |
| Images | The picture, shown inline |
Text, Markdown, CSV (.txt, .md, .csv) | The content as text |
If a file cannot be shown, the preview says "Preview not available for this file type" and invites you to download it instead. Every preview has a Download button, and you can close it with the × or the Esc key.
For older Word files that are still being read, the preview may show a "processing text" message for a moment. Close it and reopen it shortly after.
Full details are in Managing Documents.
Audio Files
Audio does not appear in the My Documents file picker. To work with a recording, attach it to a conversation instead — see Chat Attachments.
Tips
- Prefer PDF whenever the same content is available in several formats.
- Scanned pages work, and the sharper the scan, the better the text comes out. Straight, well-lit, high-contrast pages give the best results.
- Split very large files. A 200-page report split into sections uploads more comfortably than one file near the 50 MB limit — and it also makes the AI's answers easier to trace back to the right section.
- Give files meaningful names. Search in My Documents matches file names, so
2026-Q1-sales-report.pdfis far easier to find later thandocument1.pdf. - Upload in groups of 20 or fewer when adding a lot of files at once.
