FilePresto
Converts, compresses and redacts files entirely in your browser — nothing uploaded.
FilePresto is a free in-browser toolkit — compress, convert, sign, redact and tidy PDFs, photos, audio and video — that processes everything on your own device, so files never reach its servers. Every tool works free for single files, with on-device AI features like OCR, searchable PDFs and automatic face-blurring. Batch jobs are capped at 5 files and 10 free files a day with no watermark; a £3.99 24-hour Day Pass lifts those batch limits with no account needed. PDF signing is explicitly 'not certificate-backed' — a visible mark, not a legal signature.
What holds up
- +Processes every file on-device — nothing is uploaded to FilePresto's servers.
- +Covers 70+ conversions (PDF, image, audio, video) in one tool, not a single-purpose converter.
- +No account needed, even for the paid £3.99/24h Day Pass that lifts batch limits.
Mind the limits
- −Batch tools cap at 5 files and 10 free files a day — heavier use needs the £3.99 Day Pass.
- −PDF signing is a visible mark only, not certificate-backed — not a legally binding e-signature.
