How Uploads Work

Supported formats

Accessible Notes accepts three file types:

• PDF — any PDF document, including scanned PDFs
• JPEG — photos or scanned images in JPEG format
• PNG — photos or scanned images in PNG format

The maximum file size is 20 MB per file. If a file is larger than that, you'll need to reduce its size before uploading — most PDF tools and image editors can do this.

Uploading to a note

You upload files on the note draft screen, before submitting for transcription. You can add multiple files to a single note — for example, a PDF of slides and a few photos of your handwritten notes from the same lecture session.

Files are ordered by the position you add them. When transcription runs, the content from all your files is combined into a single markdown body in that order, so it helps to upload them in the sequence you want the final document to follow.

What happens after upload

Once you upload a file, it goes through an optimization pipeline in the background:

• Compression — files are compressed to reduce storage size and speed up viewing
• Thumbnail generation — small previews are generated so your files load quickly in the interface

This optimization happens automatically and doesn't affect transcription quality — the original file content is always used when your document is transcribed. You don't need to wait for optimization to finish before submitting for transcription.

How pages are counted

Page counts are used to track your weekly usage:

• PDFs — the page count is extracted automatically from the document. A 10-page PDF counts as 10 pages.
• Images (JPEG, PNG) — each image file counts as 1 page, regardless of its dimensions or content.

See Page Counts & Limits for details on your weekly allowance and what happens when you reach it.
