PDF and image file submission checklist

1. Keep the original separately

Compression, conversion, and page editing normally create a new result, but it is still easy to choose the wrong file or lose track of versions. Keep important originals in their folder and save results in another location. If an original file name contains personal or internal information, rename the submission copy as well.

2. Check the recipient’s rules as numbers

Read requirements such as “PDF only,” “under 10MB,” or “up to five pages” before processing. A 1MB, 5MB, and 10MB limit each require a different result, and email services can have a separate total attachment limit. For images, check whether the recipient requires JPG or PNG; for documents, check whether several files must be merged into one PDF.

• Does the extension match the requested format?
• Is the final size comfortably below the limit?
• Do the page count, file count, and file-name rules match?

3. Open the actual result

A file name or size shown in an upload form cannot prove that the content is correct. Open the downloaded result and inspect the first, middle, and final pages. For PDFs, check order, rotation, small text, stamps, and signatures. For images, check orientation, cropping, color, and whether a transparent background is still present.

4. Zoom in after compression

Strong PDF compression can make small text in scanned agreements or certificates difficult to read. Very low image targets such as 100KB can blur faces, logos, and document text. Choose the smallest file that still passes the limit and remains readable, rather than automatically choosing the smallest possible result.

5. Final check before submission

1. Review the recipient’s format and size requirements once more.
2. Open the output and inspect pages, text, and images.
3. Check that the file name does not expose unnecessary personal or internal information.
4. After upload, check the form’s displayed file name, size, and preview too.

Keep the confirmation email, submission number, or a screenshot of the completion screen when available. If a technical issue happens, noting the file type and browser will make support and retrying easier.
