Everything You Need to Know
Frequently asked questions and expert answers about Compress PDF to 1MB Online Free.
Is it safe to upload confidential legal, financial, or tax documents?▼
Yes. Our tools process files directly inside your browser using client-side WebAssembly. Your sensitive files never leave your local device memory, eliminating data exposure risks for bank statements, contracts, and identity documents.
What happens to my files after I finish converting or editing?▼
Because processing runs locally on your machine, your files are never retained, stored, or indexed on remote servers. Closing or refreshing the browser tab immediately purges the local memory cache.
Why do online PDF to Word converters often mess up tables and fonts?▼
Standard converters treat PDFs as raw images or disconnected text strings. Our conversion engine uses structural layout reconstruction—detecting table grids, font weights, margins, and paragraph flow—so your exported Word (.docx) file matches the original layout with editable text.
Why can't I search, select, or copy text from my scanned PDF?▼
Scanned documents save pages as flat raster images. To make the text selectable and searchable, run the document through our OCR PDF tool, which recognizes characters across 30+ languages and injects a selectable text layer beneath the image.
