Testing with a 50 MB PDF file
At 50 MB you are at half of Cloudflare’s 100 MB request limit for Free and Pro plans. Use the file to check chunked or resumable uploads, progress reporting and timeout settings.
Loading a file this size fully into memory is a common cause of server out-of-memory errors, so watch memory during the upload as well as the response code.
Use this size to check that a chunked or resumable upload reassembles to exactly the right byte count. This tool cannot split a file, so split it with your own client and compare the stored size with 52,428,800 bytes.

Limits closest to 50 MB
A 50 MB file is over nginx (1 MB), PHP (2 MB), AWS Lambda (6 MB), API Gateway (10 MB), Outlook with Exchange (10 MB), Outlook with internet accounts (20 MB) and Gmail (25 MB); under Cloudflare Free and Pro (100 MB). Sent as base64 text it stays on the same side of every limit.
| Limit | Size | Notes |
|---|---|---|
| Outlook attachment limit (internet accounts) | 20 MB 20,971,520 B | Per Microsoft Outlook guidance. |
| Gmail message size limit | 25 MB 26,214,400 B | Attachments grow about a third when encoded, so a 20 MB file can already be too big. |
| Cloudflare proxy request body (Free and Pro plans) | 100 MB 104,857,600 B | Larger requests return HTTP 413. |

50 MB PDF file FAQ
Is the 50 MB PDF file exactly 50 MB?
Yes: 52,428,800 bytes in binary units. For a decimal 50 MB, set the unit to B and enter 50,000,000.
How many pages does a 50 MB dummy PDF have?
10 pages of A4 text by default. The page count is an option and does not depend on the file size: choose 1 to 200 pages in Options and the file stays exactly 52,428,800 bytes. If the pages need more than 50 MB, the tool says the minimum size they need.
Is a 50 MB dummy PDF mostly filler?
With the default 10 pages, yes. The document is about 23 KB, so most of the 52,428,800 bytes is a PDF comment after the final %%EOF marker, outside the document structure. More pages mean less filler.
Will a 50 MB PDF file pass the Cloudflare proxy request body (Free and Pro plans)?
Yes, as a raw binary upload: it is 52,428,800 bytes under the 100 MB limit (104,857,600 bytes), which leaves room for the few hundred bytes of multipart headers. As base64 it is 69,905,068 characters, under the limit, and that is the size that counts in a JSON body or an email.
Is the file uploaded anywhere?
No. It is generated in your browser and never leaves your device.
