A FRESH START FOR YOUR PAPERWORK

Everything you need for a clearer scan.

From a phone photo to a document you can confidently review and share.

Straighten crooked scans

Trace the page with four draggable corners. Real perspective correction flattens the page and crops away the surrounding desk.

Reduce paper shadows

Adjust local illumination correction to balance uneven lighting. Review faint handwriting and colored ink before sharing.

Rotate & mirror each page

Turn sideways pages in 90° steps, or flip horizontally and vertically. Each page keeps its own settings.

Color, gray or black & white

Keep color ink, use grayscale, or adjust a black & white threshold for document text. Cleanup can be switched off.

Clean up your scanned PDF: questions & answers

Useful answers. Clear next steps.

At a glance

Clean Scanned PDF turns PDF pages or document photos into a straightened, cleaner image-based PDF. Adjust four corners per page, reduce uneven paper lighting, choose original color, grayscale or black & white, and rotate or mirror each page. Processing runs locally. Up to 12 pages, 350 MB combined input and no fixed pixel or megapixel image upload cap. Browser memory and codec limits apply. PDF pages render at 150 DPI within a 24 MP / 16,000 px output budget. Searchable text, forms and digital signatures are not retained. Start with the shared 30-minute trial; paid passes retain the same limits. Registered accounts can start 30 continuous minutes of all-tools access every 3 hours, measured from the previous start. Idle time counts; unused minutes do not roll over. Paid passes provide continuous access.

Are my documents uploaded?

No. PDF pages, photos, perspective correction and cleanup are processed on your device. Account and payment requests do not contain your documents.

What files and limits are supported?

Add PDF, JPEG, PNG, WebP, HEIC/HEIF, BMP, GIF or supported AVIF files. Work with up to 12 document pages per batch and 350 MB combined source files. Image uploads have no fixed pixel or megapixel cap; browser memory and codec limits apply. PDF pages render at 150 DPI within a 24 MP / 16,000 px output budget.

How do I straighten a crooked scan?

Select a page, drag the four numbered corner handles around its edges, then clean the document. Automatic detection is a starting point; check every corner. Rotation and mirroring are separate controls.

Can I remove shadows and the background?

The four-corner crop removes the surrounding desk or background. Local illumination correction reduces uneven paper lighting inside the document. Adjust its strength and inspect the output; it cannot recover text hidden by objects, severe shadows or blur.

How do the color modes differ?

Original color retains color ink, grayscale removes color, and black & white uses an adjustable threshold for crisp text. Shadow correction is optional in every mode. Download images or an image-based PDF and compare readability with your original.

Will searchable text, forms and signatures be preserved?

No. This cleanup tool renders pages as images. The new PDF does not retain searchable text, interactive forms, links, annotations as separate objects or digital signatures. Keep the original. Use the PDF editor OCR separately if you need searchable text.

Can I compress the cleaned PDF?

Yes. Choose Send to Compress PDF after creating the PDF. The result is stored temporarily in this browser for up to 10 minutes and consumed once by the compression tool. It is never uploaded. A target size depends on page content and readability.

Is the tool free?

All tools share a 30-minute trial without registration. For continuous access, sign in and buy an available one-time access pass. Published file, page and device limits apply to every pass. Registered accounts can start 30 continuous minutes of all-tools access every 3 hours, measured from the previous start. Idle time counts; unused minutes do not roll over. Paid passes provide continuous access.
