No subscription trap. Contenta is a one-time purchase — less than 2 months of Lightroom, and it's yours forever.
Contenta reads 100+ input formats, including JPEG, PNG, TIFF, WebP, HEIC, AVIF, BMP, GIF, PDF and 30+ camera RAW formats (CR2, NEF, ARW, DNG, RAF, and more), and writes 28 output formats.
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 30+ RAW formats from Canon, Nikon, Sony, Fuji, Panasonic, Olympus, and more. Full white balance, denoising, and color adjustment controls are built in.
Every feature, every file and no time limit. Each batch converts in full; results carry a small watermark until you pick up to 10 of them to keep clean. Those picks count once per PC, not per batch, and a batch of 500 costs none until you choose. A license ($129 once) removes the watermark from everything you convert.
No. Contenta Converter is a one-time purchase. You pay once and own it forever, including all future updates. No monthly or yearly fees.
