No signup or account is required โ€” just drop your file and convert.

Files are processed server-side using industry-standard tools (Sharp for images, FFmpeg for audio/video, LibreOffice/Pandoc for documents). Files are encrypted in transit, processed on isolated servers, and automatically deleted within 24 hours. CocoConvert never reads or shares your data.

Beyond conversion, CocoConvert also offers compression tools (JPG, PNG, WebP, GIF, etc.) and image editing tools (resize, crop, rotate, grayscale, watermark) โ€” all in the browser with batch processing support on paid plans.
