Advanced: test an upload limit

Enter the byte limit above, then choose one byte below, the exact limit or one byte above. Each choice uses the same base: 26,214,400 B. Generate and download each file to test your endpoint.

What to test with this JPG fixture

  • Compare 25 MiB with the actual server cap. A decimal 25 MB limit is only 25,000,000 bytes; filename labels alone do not establish acceptance.
  • Testing what your users see when an image is too large for an email attachment.
  • Uploading through GitHub's web interface to see the browser upload limit.
  • Checking image hosting flows that advertise a 25 MB ceiling.

Limits it lands on

  • Gmail and Yahoo Mail limit attachments to 25 MB; with base64 encoding this image becomes about 35 million bytes, so Gmail offers a Drive link instead.
  • GitHub's web uploader accepts files up to 25 MB; larger files must be pushed with Git.

What is inside the file

Around 400 COM segments. The JPEG remains a single baseline image, so even old decoders handle it.

Size check: 25 × 1,048,576 = 26,214,400 bytes exactly.

Questions

Why does Gmail turn it into a Drive link?

Gmail measures the attachment after encoding. A file that is 25 MB on disk is well over 25 MB once encoded for email.

Can I upload it on GitHub in the browser?

It is right at the 25 MB browser limit; use git push for anything you need to be sure about.

Does 25 MB on this page mean 25000000 bytes?

This legacy URL selects 25 MiB: 26,214,400 bytes. A decimal 25 MB cap is 25,000,000 bytes. Select decimal MB or enter exact bytes on the JPG format page.
