OCR Toolv1.0.0
Runs Tesseract.js OCR in the browser to extract plain text from JPG, PNG, GIF, WEBP, and PDF files up to 20 MB each, with no upload to a server. Renders PDF pages to images before recognition, queues up to 8 files per batch, and reports a per-file confidence score. Supports 13 languages and a fast or high-accuracy model choice.
Documentation
Run OCR in a few steps and export clean text for editing, sharing, or storage. The tool performs OCR on images directly and renders each PDF page to an image before recognition. You can select a global language and per-file language to improve accuracy. Use high-accuracy mode for cleaner results or fast mode for quick drafts. Turn on deskew and denoise to help with tilted or noisy scans, and enable auto-rotate to fix sideways photos.
- Open the upload area, then drag and drop files or click to select them. You can also press the paste button and paste from the clipboard.
- Pick the Global OCR language, then adjust Quality (Fast or High accuracy) and optional processing (Deskew/Denoise, Auto-rotate, Low-memory mode).
- For any file that needs a different language, set it in the file card before starting OCR.
- Click Start OCR and watch the live status and spinner. The tool processes files in sequence and updates progress for each one.
- Review results in the Results section. Click Copy text per file or Copy all to consolidate outputs.
- Click Download .txt per file or Download all as .zip to save everything with a manifest.
- Use Clear to reset the session, files, and results. Control settings persist to localStorage so you can keep your preferred defaults.
Limits and logic (plain text for reference): Max files per batch = 8; Max file size = 20 MB; Max combined batch size = 80 MB; Max total PDF pages = 60. PDFs are rendered to images with PDF.js, then passed to Tesseract.js for recognition. Confidence shows an approximate quality score (0 to 100). High accuracy mode uses higher-quality language models; fast mode uses lighter models that favor speed. Preserve interword spaces to maintain readable spacing in output.
Apply the OCR Tool to speed up study, research, recordkeeping, and content creation. Extract text from lecture slides, whiteboard photos, invoices, or printed forms and move the content into notes, spreadsheets, or writing apps. Improve clarity by running deskew, denoise, and auto-rotate so you can recognize text from mobile snapshots and older scans. Save time by batching files and exporting a single ZIP with consistent, plain-text outputs.
- Study and notes: Convert class handouts, textbook excerpts, and whiteboard photos into searchable notes for exam prep.
- Workplace documents: Capture text from receipts, packing slips, contracts, and reports to streamline bookkeeping and audits.
- Research and archiving: Digitize magazine clippings and historical pamphlets to create a plain text corpus for analysis.
- Content repurposing: Turn scanned articles or print designs into editable text for blogs, newsletters, and accessibility versions.
- Localization prep: Extract source text for translation workflows, then feed it to translation tools or CAT platforms.
- Developer utilities: Generate plain text from screenshots of logs or terminal output to share snippets and error messages.
- Accessibility support: Provide text alternatives for images and scanned PDFs to improve screen reader compatibility.
- Administrative efficiency: Batch scan and convert recurring forms so teams can paste clean text into CRMs or spreadsheets.
Adopt a consistent routine for scanning, naming files, and selecting languages to improve accuracy over time. Use high-accuracy mode for important documents and fast mode for quick drafts. Keep outputs in plain text to simplify QA, version control, and downstream formatting. When in doubt, re-run a single file with a different language or enable deskew and denoise to improve results without repeating the entire batch.
