How OCR Files works
A practical walkthrough of the OCR Studio tool at https://ocrfiles.online/
OCR Files converts images and PDFs into editable text in your browser. Follow the steps below from upload to export. No sign-up is required.
Step 1 — Choose your input
On the home page you can add content in two ways:
- Files tab — Click to browse, drag and drop, or paste files. Supported formats include PDF, PNG, JPEG, WebP, GIF, HEIC/HEIF (converted automatically), TIFF, AVIF, and BMP.
- Live camera tab — Point your device camera at text (signs, labels, documents) and capture a frame. On mobile, camera access requires a secure (HTTPS) connection.
You can process multiple files in one batch (up to 20 files, each up to 50 MB).
Step 2 — Configure OCR options
Before running OCR, adjust options in the toolbar:
| Option | What it does |
|---|---|
| Mode | Auto picks document or photo processing automatically. Document suits scans and PDFs; Photo suits signs, plates, and casual photos. |
| Language | Set a hint (English, Hindi, Gujarati, Tamil, Arabic, Chinese, etc.) or leave on Auto-detect when unsure. |
| Tables (PDF/docs) | Keep tables inline (default), or export them as Markdown or HTML tables in the output. |
| Structured extract | Optional presets: invoice, receipt, license plate, ID card, or business card — returns organized fields when the layout matches. |
| Pages |
For PDFs only — leave blank for all pages, or enter ranges like 1-3,
1,5,9.

Step 3 — Preprocess images (optional)
For image files (not PDFs), open the preprocessing panel to tweak contrast, brightness, and rotation. Apply a preview, then run OCR for better results on faded scans or skewed photos.
Step 4 — Run OCR
Click Extract text (or the equivalent run button). Your file is sent securely to our server, processed with Mistral OCR, and the extracted text appears in the editor. A progress indicator shows while processing; batch jobs run file by file.
When structured extraction is enabled, a separate panel shows parsed fields (e.g. invoice line items or receipt totals) alongside the raw text.
Step 5 — Edit and refine
- Edit text directly in the output area.
- Use Search & replace to fix repeated OCR mistakes.
- Review metadata such as engine type (document vs photo), page count, and confidence hints.
Step 6 — Translate (optional)
Select a target language in the translate bar and run translation. The original text is preserved so you can switch back. Translation uses the same secure API backend as OCR.
Step 7 — Read aloud (optional)
Use Read aloud to generate English speech from the current text. Play the audio in the browser or download it. Voice gender can be adjusted where supported.
Step 8 — Export or copy
Save your work in a format that fits your workflow:
- .txt — Plain text
- .md — Markdown (includes document title)
- .docx — Microsoft Word document
You can also copy text to the clipboard from the editor.
History
Recent extractions are stored in your browser’s local storage (up to 20 entries on the same device). Open History from the header to reload a past result, or clear history when you no longer need it. History does not sync across devices.
Tips for better results
- Use good lighting and a flat, in-focus photo when using the camera.
- For multi-column PDFs, try document mode and table export options.
- Set the correct language hint for non-Latin scripts (Devanagari, Arabic, CJK, etc.).
- Preprocess low-contrast scans before running OCR.
- Always proofread output — OCR can misread similar characters (0/O, 1/l, etc.).
