Pdf Ocr To Text
Each language downloads ~3-15 MB of model data the first time. Cached afterward.
Upload a PDF to begin
Runs entirely in your browser using tesseract.js + pdfjs-dist. No upload, no API. Print + clean handwriting OCR accuracy: 85–95%. Cursive or messy handwriting: 50–70%. Math notation, complex tables, and 2-column layouts perform worst.
Extract text from scanned or handwritten PDFs entirely in your browser. Uses Tesseract.js — no upload, no API key, supports English, Spanish, French, German. Document and image format conversions sit between you and the deliverable; the tool that converts in 3 seconds saves cumulative hours.
Wrong-format submission to a portal, application, or client is one of the most common reasons projects get bounced back. The gap between “rough estimate” and “defensible number” is exactly where good tooling earns its keep — the math is reproducible, but knowing which inputs matter and what the result means is half the work.
For batch conversions, prefer a CLI tool (ImageMagick, ffmpeg, ghostscript) to a browser; browser is for one-offs. A common pitfall: ignoring color profiles (sRGB vs Adobe RGB vs Display P3 produce different results). Treat the tool’s output as a starting point and validate against authoritative sources for any consequential decision.
Nasıl Kullanılır
- Paste or upload the input in its current format.
- Pick the target format and any options (quality, encoding).
- Run the conversion (browser-side, no upload to server in our implementation).
- Verify the output matches your expectation before downloading.
- Save with a clear filename so the conversion is reversible.
Ne Zaman Kullanılır
- Ad-hoc conversions where the file isn’t sensitive enough to require local processing.
- One-off conversions that don’t justify installing dedicated software.
- Educational demonstrations of format differences and tradeoffs.
- Quick previews of how a file would look in a different format.
Ne Zaman Kullanılmaz
- Sensitive documents (legal, medical, financial) where retention by a third-party converter is a risk.
- Production workflows requiring deterministic, repeatable output.
- Format-specific conversions requiring fine-grained control over compression, color, or metadata.
- Bulk conversions of hundreds of files (use a scriptable CLI).

Sık Sorulan Sorular
Can I batch-convert files?
Browser-based tools handle one-at-a-time efficiently. For 100+ files, a CLI tool (ImageMagick, ghostscript, ffmpeg) is dramatically faster and scriptable.
What happens to metadata?
Strip metadata by default for privacy where applicable. Photos: EXIF including GPS removed. Documents: author / edit history sanitized. Toggle if you need to preserve metadata.
Is the conversion lossy or lossless?
Depends on the source and target formats. PNG to JPG is lossy (re-encoded); PNG to WebP-lossless is lossless. The tool indicates which mode is used.
What’s the maximum file size I can convert?
Browser memory limits files to roughly 100MB-500MB depending on browser, OS, and available RAM. For larger files, use a desktop tool.
Does it preserve quality?
Yes for default settings. For maximum control, adjust quality slider or compression level. Lossy formats degrade with each re-encode — convert from the original whenever possible.
How does file size change?
Varies by format pair. JPG to WebP at same quality typically saves 25-35% file size. PNG to JPG saves 60-80% but is lossy. Lossless conversions preserve file size or grow it slightly.
