Why Use IKAI Converter

Every Format.
Maximum Control.

100% Browser-Based
All conversion happens locally using the Canvas API. Your files never leave your device — no uploads, no server, no privacy risk.
Per-File Format Control
Each file in your batch can have its own output format. Convert some to WebP, others to PNG — all in a single pass.
RAW & Professional Formats
Supports DNG, CR2, CR3, NEF, ARW, RAF, ORF, RW2, HEIC, PSD, and more — convert professional camera formats to web-ready images instantly.
Bulk ZIP Download
After conversion, download all files at once as a neatly packaged ZIP archive — or grab individual files with a single click.
Quality Slider
Fine-tune the quality level for lossy formats like JPG and WebP. Lossless formats like PNG and BMP are always output at full quality.

Questions

Frequently Asked

Yes, completely free. No registration, no watermarks, no file count limits, no daily caps. The tool runs entirely in your browser — IKAI Media does not process or store your files.
No. All conversion happens locally in your browser using the Canvas API. Your files never leave your device. There are no uploads, no server processing, and no data retention of any kind.
Yes. Each file has its own format selector, so you can convert different files to different formats in the same batch. You can also use the global "Convert all to" dropdown to set the same format for every file at once.
The quality slider controls the compression level for lossy formats like JPG and WebP. Higher values (closer to 100%) produce better image quality but larger file sizes. PNG and BMP are lossless and are not affected by this setting.
After conversion, a green "Download All (ZIP)" button appears. Clicking it packages all successfully converted files into a single ZIP archive. You can also download files individually using the download icon next to each file.
