See allPDF Compressor
Trims PDF file size by stripping redundant metadata and optimizing object streams — best on text-heavy documents. Cannot recompress embedded images (the main size driver); for scan-heavy PDFs use Bulk PDF Size Reducer. Handles PDFs up to 125MB.

Turn photos and scanned images into a professional PDF document. Upload multiple images, reorder, and combine into a single PDF. Documents stay on your device — editing and conversion run locally in your browser.
PDF to Word
Extracts PDF text into a Word-readable .doc file (HTML-based), one paragraph per detected line. Tables, columns, images, and the original layout are not preserved — review complex documents after conversion.

Bulk Face Anonymizer
Detect and blur or pixelate faces across whole photo batches with on-device BlazeFace (one shared model download for the batch). Faces need confidence above 0.5 and size above 8px; faceless files are skipped with an error. Outputs PNG as <name>-anonymized.png — local processing, 2 free batches a day.
Frequently Asked Questions
How skewed is too skewed?
Feeder tilt under ~10° corrects cleanly with text detection; pages past 15° or with curved book-spread distortion need manual rotation first. Preview the worst page before batching all 30.
Does deskewing hurt OCR later?
It helps enormously — straight text lines OCR at 95%+ versus 70% tilted. Always deskew before OCR, never after.
Will margins change?
Slightly — rotation re-frames content with small edge variance. Run crop after deskew for uniform clean margins.
Are my scans uploaded?
No — deskewing runs locally in your browser. Only the final save touches the network — downloads are unlimited.
