> What to do with bank statements in a zip file: unpacking on a computer or phone, password-protected archives, and checking every month is there.
Bank statements in a zip file have to be unpacked before any converter can read them, because a zip is a container, not a PDF. Extract the archive to an ordinary folder, confirm each month's PDF opens on its own, and only then convert. Converting straight from the archive preview is where files go missing.

## Why do bank statements arrive in a zip file?

Statements arrive zipped because one archive is easier to send than twelve separate PDFs. Online banking export tools, accountants and lenders often bundle a year of statements into a single download. Zipping also shrinks the transfer a little and keeps the files together, which helps when an email system limits the number of attachments.

A zip file is a compressed folder. It holds copies of the PDFs, sometimes with subfolders, in a packed form that a PDF reader cannot open directly. To a converter that expects a PDF, the archive is just an unknown file type.

Some banks name the archive after the account and date range, while the PDFs inside carry their own names. Read both. The archive name tells you what was meant to be inside; the file names tell you what actually is.

## Unzipping bank statements on a computer

On a computer, extracting the zip takes one menu choice. On Windows, right-click the zipped folder, choose Extract All and follow the prompts, as described in [Microsoft's guide to zipping and unzipping files](https://support.microsoft.com/en-us/windows/zip-and-unzip-files-8d28fa72-f2f9-712f-67df-f80cf89fd4e5). On a Mac, double-clicking the archive unpacks it into a folder beside it.

The mistake here is subtle. Windows lets you open a zipped folder and look inside it as if it were a normal folder, so it is tempting to double-click a statement right there. That works for viewing, but a file opened from inside the archive may be a temporary copy, and dragging it to an upload page can fail or send the wrong thing. Extract first, then work from the new folder.

Pick a destination you will find again, such as a folder named for the account and year. Leave the original zip where it is until the checks at the end of this post pass.

## Opening a statement zip file on a phone

Most phones can unpack a zip in their built-in files app. On an iPhone, tapping a zip in the Files app usually expands it into a folder next to the archive. On Android, the files app from the phone maker or Google typically offers an Extract option when you tap the archive.

If your files app shows the archive but offers no way to open it, save it to a computer instead of installing an unknown unzip app. Statement archives hold account numbers and transaction history, so a tool you have not vetted is a poor place to open them.

After extracting on a phone, open one of the PDFs to make sure it displays. Mail apps sometimes save only a preview of an attachment, and a preview of a zip is not the zip itself.

## What if the bank statement zip asks for a password?

A password prompt on a zip belongs to the archive, not to the statements. The bank or sender set it when they built the zip, and they normally send it separately, by text message or in a second email. It is often different from any password on the PDFs inside.

Expect two layers on some downloads. You type one password to open the archive, then the extracted PDFs may ask for another before they display. Those PDF passwords, and the copy locks that stop text from being selected, are a separate problem covered in [converting a secured PDF to Excel](/blog/secured-pdf-to-excel).

Windows' own Extract All may not get you this far. [Microsoft's zip guide](https://support.microsoft.com/en-us/windows/zip-and-unzip-files-8d28fa72-f2f9-712f-67df-f80cf89fd4e5) notes that Windows 11, version 24H2, can't open or create encrypted archives and points to third-party tools such as 7-Zip or WinRAR instead.

If the zip rejects the password, check for a capital letter, a trailing space copied from an email, or a date in a different format. Ask the sender to resend rather than guessing repeatedly.

## Checking every month made it out of the zip

Checking the extracted folder takes two minutes and saves a failed reconciliation later. Archives can hold nested zips, duplicate files with "(1)" in the name, or a month that was never included. Count and compare before you convert anything.

Run this checklist on the folder you extracted to. The example assumes a year of monthly statements.

1. **File count.** Twelve months should give twelve PDFs. A thirteenth file is often a duplicate or a cover letter.
2. **Month sequence.** Sort by name and read the periods. A gap, such as March to May, means April is missing from the archive.
3. **File names.** Look for a second zip inside the folder. Extract it too, or its months will never reach the converter.
4. **File sizes.** A PDF of a few kilobytes beside others of a few hundred is likely damaged or empty.
5. **Each PDF opens.** Open every file once. Look at page orientation as you go; sideways scans need the fix in [converting a rotated PDF to Excel](/blog/rotated-pdf-to-excel) before they read well.

Once the files pass, decide whether to send them one at a time or together. A year of statements adds up, and [PDF upload size limits](/blog/pdf-upload-size-limit) explains what to do when a converter turns a large file away.

FastBankConvert takes the unzipped statement PDF itself, dragged onto the page or picked from your phone, and tells you before download when a statement's balances do not add up. It has not opened yet; you can [sign up through Get started](/get-started) to hear when it does.
