No subscription trap. Contenta is a one-time purchase — less than 2 months of Lightroom, and it's yours forever.
Contenta reads and writes 60+ formats including JPEG, PNG, TIFF, WebP, HEIC, AVIF, BMP, GIF, PDF, and 25+ camera RAW formats (CR2, NEF, ARW, DNG, RAF, and more).
There is no limit. Contenta uses multi-core processing to convert thousands of images in minutes. Users regularly process 10,000+ photos in a single batch.
Yes. Contenta supports 25+ RAW formats from Canon, Nikon, Sony, Fuji, Panasonic, Olympus, and more. Full white balance, denoising, and color adjustment controls are built in.
The 30-day trial includes every feature. The first 10 images you convert are saved without a watermark. That allowance is counted once across the whole trial, not per batch, so conversions after it carry a small watermark. A license removes it.
No. Contenta Converter is a one-time purchase. You pay once and own it forever, including all future updates. No monthly or yearly fees.
