"As a book scanner, I deal with TIFF files daily – they're huge. reaConverter compresses them to PDF or JPEG without losing any detail. I've saved terabytes of storage and still have archive‑quality images. This software paid for itself in storage costs alone."

Edward N.

Digitization Specialist

"My scanner saves everything as massive TIFF files, which are impossible to email. reaConverter lets me batch-convert them to searchable PDFs with tiny file sizes. My clients actually get their documents now!"

Ryan Park

Freelance Archivist

"I work in medical imaging, and we receive TIFFs from various sources. reaConverter converts them to DICOM‑compatible formats while preserving all pixel data. It's HIPAA‑friendly because it works offline – no data leaves our network. Essential for our lab."

Dr. Harold Kim

"I needed to convert TIFF to multi‑page PDF for an archive project. reaConverter handled it effortlessly – 2,000 pages in one batch. The output PDF was searchable (thanks to OCR) and had the same resolution as the originals. Absolutely brilliant."

Patricia O'Brien

Satisfied Customer

"I'm a graphic designer, and I often receive TIFF files from photographers. reaConverter converts them to editable PSDs with layers intact (where possible). It even keeps the colour profiles. This has streamlined my collaboration with clients tremendously."
