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) |
| Audio | MP3 (.mp3), WAV (.wav), M4A (.m4a), OGG (.ogg), FLAC (.flac), WebM (.webm) |
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 |
The 50 MB limit is the same for everyone — it is not a setting your administrator can change.
What you see when a limit is hit
| Message | What it means | What to do |
|---|---|---|
| "This file cannot be used." | The file is in a format that is not on this page | Save or export the file as PDF and upload that |
| Already uploaded (in a multi-file upload) or "This file has already been uploaded." (single file) | The exact same file content is already in your library | No action needed — the existing copy is already there |
| "You have reached your plan limit. Please upgrade to continue." | 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 |
| "This file is empty." | The file is 0 bytes | Check the file opens on your computer, then upload again |
| "You have uploaded too many files. Please wait a moment and try again." | You reached the hourly upload limit | Wait a while, then continue |
A file over 50 MB is refused as well. Split it into smaller files, or compress it.
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 window 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.
If your upload is refused because of the file type, 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.
- Audio files are turned into text, so you can ask the AI about what was said in a recording.
If the text of a file could not be read, the upload still succeeds and the file is stored — but the document's card shows an amber status line such as "No readable text found — probably a scan without OCR", with a Try again link. See Reading status.
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 |
Audio, older Excel and PowerPoint files (.xls, .ppt), OpenDocument | No preview — download the file to open it |
If a file cannot be shown, the preview says "Preview not available for this file type" and "Please download the file to view it". 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 "Processing text…" for a moment. Close it and reopen it shortly after.
Full details are in Managing Documents.
Audio Files
You can upload audio recordings to My Documents — MP3, WAV, M4A, OGG, FLAC and WebM files appear in the file picker like any other type.
- The recording is turned into text after the upload, so the AI can answer questions about what was said.
- Audio cards have a pink icon. There is no audio tab above the grid — find your recordings under All.
- Audio cannot be played or previewed on the page. Download the file to listen to it.
For a one-off question about a recording, you can also 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.
