Why Inspect a Document Before Sending?

-
Charts are vector objects and are left alone.
Frequently Asked Questions
Answers to common questions about this tool.
My workbook has no pictures — why is it big?
Then the size is cells, formats and cached formula results. Delete empty formatted rows, clear unused ranges and save; this tool can only shrink pictures and tighten the packing.
Will formulas still calculate?
Yes. The sheet XML is copied byte-for-byte; formulas, names, validation and conditional formats are all kept.
Are the numbers uploaded?
No. The work is done in your browser tab and the file is downloaded straight back.
Does Compress Excel Workbook change my file?
The inspection tools only read the file and report what they find, so your document is untouched. Tools that split, merge or compress give you a new file and leave the original as it was.
What is PDF/A and do I need it?
PDF/A is a version of PDF made for keeping documents readable for many years. Some courts, government offices and archives ask for it. If a portal does not mention it, an ordinary PDF is fine.
Can I use Compress Excel Workbook without signing up?
Yes. No account, no email and no fee. Drop in the file and the report or result appears on the page, ready to read or download.
Why was my PDF rejected by a portal?
Common reasons are a file that is too large, the wrong PDF version, a password, missing fonts or pages of the wrong size. Checking those details here usually points to the cause.
