300 DPI Smart PDF Image Downscaler
Scanned PDFs with 600–1200 DPI resolution create 20MB–50MB files that get rejected by portals. Resample image streams to 300 DPI (the exact government OCR standard) to shrink file size while preserving text clarity.

All PDF analysis, form field flattening, and compression happen directly inside your web browser. Your sensitive documents (passports, tax IDs, visa forms) never leave your device.
