How to Deskew Scanned PDF and TIFF Files

Scanned documents always require post-formatting due to blank pages, wrong paper sheets orientation, big scanned files size, etc. With Tiff PDF Cleaner you can deskew scanned PDF and TIFF images and do all these arrangements with ease. The program straightens crooked pages in both PDF and TIFF, and can convert scanned TIFF to PDF and vice versa.

Quick answer: To deskew a PDF or TIFF in batch, open Tiff PDF Cleaner, check the scanned PDF or TIFF files in the list, click the PDF or TIFF icon to open the options, enable deskew (plus auto crop, blank-page detector, and compression), then start processing. Every selected file is straightened and cleaned at once, with detected blank pages saved separately so no data is lost.

Processing scanned files inside Tiff Pdf Cleaner includes the following:

Merging scanned files into one
Splitting them by blank pages
Adding various tags to header and footer
Setting PDF properties or TIFF tags
Compressing scanned images
Auto crop.

A huge bonus is ability to perform all these actions in batch. This means you can process all scanned PDF or TIFF files together. In order to deskew PDF or TIFF files in batches you need to select all scanned sources for processing. Just check off scanned files in the list and press on the icon of the required format (PDF or TIFF). You will see the list of options popped up. There you need to setup all parameters for cleaning and formatting scanned images.

Please note that Tiff Pdf Cleaner has adjustable blank pages detector. You can change its sensitivity depending on the quality of scanned material. This option is necessary when you decide to split scanned files by blank pages.

Tiff Pdf Cleaner helps to avoid any data loss. For this all pages detected as blank can be saved to a separate document for further review. Additionally you can crop scanned pages to remove extra frame. The program automatically defines blank space from the sides of each scanned image. Scanned TIFF images can be compressed by one of supported methods or left uncompressed.

There is a command line support for processing scanned files from the console. You can deskew PDF or TIFF files by one command, setting all parameters in text. Try Tiff Pdf Cleaner now!

Tiff PDF Cleaner Customer Reviews 2026

Rate ItRated 4.8/5 based on customer reviews

"Our document feeders produce slightly rotated scans on about 15% of pages. Tiff PDF Cleaner's auto-deskew straightens them all in batch. We run it on every scanning session before archiving. The OCR accuracy improved noticeably after we started deskewing first."

5 Star Helen Park Digitization Coordinator, Seoul National Archives

"We process faxes stored as TIFF for corporate clients. Fax pages are almost always slightly skewed. Tiff PDF Cleaner deskews, removes blank pages, and crops borders in one pass. Three operations that used to require three different tools."

5 Star Frank Mueller Production Manager, ScanTech Document Services

"Our older scanner produces crooked pages that look unprofessional in client reports. The auto-deskew feature fixes them without any manual intervention. We just add the folder and click Start. Very straightforward."

FAQ: Deskewing Scanned TIFF Images ▼

What does deskew mean?

Deskewing straightens a scanned image that was captured at a slight angle. When paper feeds through a scanner crooked, the resulting image is tilted. Deskew detects the angle and rotates the image to align text horizontally.

Can Tiff PDF Cleaner deskew and remove blank pages at the same time?

Yes. Enable both auto-deskew and blank page detection in the settings. Both operations are applied to every page in a single batch pass.

Does deskew work on multi-page TIFF files?

Yes. Each frame in a multi-page TIFF is analyzed and straightened independently. Pages that are already straight are left unchanged.

Does deskewing affect image quality?

The rotation uses interpolation to maintain image quality. For bitonal (black-and-white) TIFF files, the process preserves sharp edges. For color or grayscale, quality loss is minimal and usually unnoticeable.

Can I deskew PDF files too?

Yes. Tiff PDF Cleaner processes both TIFF and PDF files. Scanned PDF pages are deskewed the same way as TIFF frames.

Is there a command-line option for deskewing?

Yes. The command-line interface supports all processing options including deskew, making it suitable for automated workflows and server-side batch processing.
