Omni Scanner

Scan with a camera or import pages for free. Correct document edges, review OCR beside each image and export organized scans, searchable PDFs or receipt records.

How to use

  1. Capture or import images, PDFs, TIFF, Office, text and one-level ZIP files; check order and sources.
  2. Adjust corners for perspective correction, tune filters, rotation and shadows, or split book spreads. Add visible signatures, text or permanent pixel redaction.
  3. Run batch quality review and inspect low-resolution, dark and low-detail candidates against processed thumbnails. Recognize Chinese / English and review text beside the scan. Pixel edits clear previous OCR.
  4. Reuse recipes, classify with the first matching rule and rename. Review receipt rows and export separate currency totals. Check missing page numbers and recognize only needed pages, then export documents, save projects and back them up.

Try an example

Try the three-page sample with English OCR. The receipt should include TOTAL USD 128.50 and the card provides contact candidates. Redacting text clears previous OCR; scanned PDFs discard original hidden layers.

Limits and privacy

Up to 50 files / 150 MB per batch, 40 MB per file, 100 pages and 3000 pixels per edge. Office content is reflowed. OCR supports Simplified Chinese / English; review handwriting and complex tables. Full backups include uncropped pages and must not be shared as redacted deliverables. AI book flattening, cloud collaboration, fax, direct hardware scanning and authenticity checks require added services.

Common questions

Are scans uploaded?

No. Capture, processing, OCR and export run in your browser. Translation uses its service only after you explicitly submit text there.

Why is searchable PDF unavailable?

Every selected page needs a current OCR PDF. Pixel edits clear OCR; text corrections clear the old search layer. Recognize again.

Do recipes and ledgers run or save automatically?

Recipes reuse settings and confirm selected pages. Recognition, renaming and classification require your action. Apply ledger fields to pages before saving the project; review state belongs to this session.

How can I continue on another device?

Download a full project backup and restore it on the other device. AES-GCM encryption is optional; lost passwords cannot recover backups.

Free use and requirements

Use this tool for free without a KitNelo account. Processing runs in your browser; input limits, browser support and device memory still apply.

Searchable PDF needs current OCR on every selected page. Pixel edits clear old recognition; review OCR before export.

Free online functions: steps and checks

Scan Documents with Your Camera for Free

Capture a document with a supported camera or import an existing image, then correct its page edges. Inspect the crop for clipped characters and organize the pages before export so the saved scan contains the complete intended document.

Create a Searchable PDF from Scans for Free

Recognize text on every selected page and compare the OCR with the scan before creating a searchable PDF. Pixel edits clear earlier recognition, so run OCR again after changing an image to ensure the exported text matches the current page.

Review Receipt OCR Beside the Scan for Free

Inspect recognized receipt text and records alongside their original page images before saving the results. Correct misread digits and labels manually, especially around totals or faint print, rather than assuming readable OCR is a verified financial record.

Correct document scan perspective for free

Import a photographed document and align the detected corners with the paper edges. Apply the perspective correction and inspect all four sides for cropped content, especially when the original was photographed at a steep angle.

Enhance document scans and reduce shadows for free

Choose a scan enhancement preset and compare it with the original photograph. Adjust the result for legible text while retaining faint handwriting, stamps and colored information that strong contrast or shadow removal might obscure.

Review batch scan quality for free

Inspect the batch quality results before exporting a scan collection. Revisit pages flagged for low resolution, darkness or low detail, and compare them with their source photos. Automated checks help prioritize review but do not certify document accuracy.

Proofread OCR beside scanned pages for free

Open the recognized text beside its source scan and correct uncertain characters, names and numbers. Review reading order and line breaks before copying or exporting. The side-by-side view supports proofreading rather than guaranteeing recognition accuracy.

Read QR codes and barcodes from scans for free

Select the code-reading function and provide a clear image of the code. Inspect the decoded value before copying or opening it. A successfully decoded URL or product code does not establish the trustworthiness of its destination.

Convert business card scans to VCF for free

Review the recognized contact fields from a business card, correcting phone numbers, names and email addresses. Export a VCF only after checking the field mapping, then inspect the contact in your address book before relying on it.

Classify and rename scanned documents for free

Organize imported scans by document type and review the proposed filenames. Keep identifying fields consistent across the batch and avoid putting sensitive details into filenames that could become visible when the exported files are shared.

Save and reuse scan recipes for free

Save a repeatable scan configuration as a recipe and import it for a similar batch. Inspect the first processed page before applying the settings broadly; paper colors, lighting and document layouts can differ between captures.

Total reviewed receipt amounts by currency for free

Correct receipt dates, amounts and currency fields before using the ledger summary. Review totals within each currency and keep the source receipts. These figures organize entered data and do not replace accounting review or perform automatic currency conversion.

Arrange paired ID card scans for free

Select the front and back images and inspect their placement in the paired layout. Check orientation, margins and readable details before export. Use only documents you are authorized to handle and remove unnecessary copies after the task.

Create encrypted scan project backups for free

Export a scan project with its encryption option and retain the password separately. Test restoring a nonsensitive project before depending on the backup. Losing the password can prevent access, and encryption does not protect files after you decrypt them.
