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.

File & Format Converters · Free tool

PDF OCR to Text

Convert scanned and handwritten PDFs to text using Tesseract.js directly in your browser. Free, instant extraction with no uploads, sign-up, or API key required.

Updated June 2026

OCR language

Each language downloads ~3-15 MB of model data the first time. Cached afterward.

Upload PDF (browser-only — never uploaded anywhere)

Upload a PDF to begin

Works on scanned PDFs and photo-based documents. Pure-browser OCR; nothing leaves your device.

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.

What it does

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.

How to use it

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.

When to use this tool

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.

When not to use it

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).

Common use cases

A developers shipping web-optimized images working through pdf ocr to text for a real decision.
A designers preparing assets for delivery working through pdf ocr to text for a real decision.
A social-media managers preparing platform-specific assets working through pdf ocr to text for a real decision.
A students and academics submitting assignments working through pdf ocr to text for a real decision.

Show the math + sources

Formula

For each PDF page: render with pdfjs-dist at 2× scale to a canvas. Pass the canvas to tesseract.js with the user-selected language model. Concatenate per-page output with '--- Page N ---' separators. All processing in-browser; no network calls after model download.

What this assumes

Tesseract OCR accuracy: 85-95% on print + clean handwriting, 50-70% on cursive or messy handwriting, lower on math notation, multi-column layouts, and complex tables. Models for each language are 3-15 MB each, downloaded once and cached in the browser. Performance is CPU-bound (typical 5-15 seconds per page on consumer hardware). For higher accuracy on scanned documents at scale, cloud OCR services with GPU acceleration outperform but require uploading.
